I have been an avid reader of SearchStorage Storage magazine for many years now and have been downloading their free PDF copy every month. Quietly snugged at the end of January 2012′s issue, there it was, the Storage magazine 6th annual Quality Awards for NAS.
I was pleasantly surprised with the results because in the previous annual awards, it would dominated by NetApp and EMC but this time around, a dark horse has emerged. It is Oracle who took top honours in both the Enterprise and the Mid-range categories.
The awards are the result of Storage Magazine’s survey and below is an excerpt about the survey:
In both categories covering the Enterprise and the Mid-Range, the overall ratings are shown below:
Surprised? You bet because I was.
The survey does not focus on speeds and feeds or comparing scalability or performance. Rather, the survey focuses on the qualitative aspects of the NAS products. There were many storage vendors who were part of the participation lists but many did not qualify to be make a dent of what the top 6 did. Here’s a list of the vendors surveyed:
The qualitative aspects of the survey focused on 5 main areas:
- Sales force competency
- Initial Quality
- Product Features
- Product Reliability
- Technical Support
In each of the 5 main areas, customers were asked a series of questions. Here is a breakdown of those questions of each area.
Sales Force Competency
- Are the sales force knowledgeable about their products and their customer’s industries?
- How flexible are their sales effort?
- How good are they keeping the customer’s interest levels up?
Initial Product Quality
- Does the product need little or no vendor intervention?
- Ease of installation and ease of use
- Good value for money
- Reasonable requirement from Professional Service or needing little Professional Service
- Installation without defects
- Getting it right the first time
- Storage management features
- Mirroring features
- Capacity scaling features
- Interoperable with other vendor’s products
- Remote replication features
- Snapshotting features
- Vendor provide comprehensive upgrading procedures
- Ability to meet Service Level Agreement (SLA)
- Experiences very little downtime
- Patches applied non-disruptively
- Taking ownership of the customer’s problem
- Timely problem resolution and technical advice
- Vendor supplies support contractually as specified
- Vendor’s 3rd party partners are knowledgeable
- Vendor provide adequate training
These are some of the intangibles that customers are looking for when they qualify the NAS solutions from vendors. And the surprising was Oracle just became something to be reckoned with, backed by the strong legacy of customer-centric focus of Sun and StorageTek. If this is truly happening in the US, then kudos to Oracle for maximizing the Sun-Storagetek enterprise genes to put their NAS products to be best-of-breed.
However, on the local front, it seems to me that Oracle isn’t doing much justice to the human potential they have inherited from Sun. A little bird has told me that they got rid of some good customer service people in Malaysia and Singapore just last month and more could be on the way in 2012. All this for the sake of meeting some silly key performance indices (KPIs) of being measured by tasks per day.
The Sun people that I know here in Malaysia and Singapore are gurus who has gone through the fire and thrived and there is no substitute for quality. Unfortunately, in Oracle, it’s all about numbers, whether it is sales or tasks per day.
Well, back to the survey. And of course, the final question would be, “Is the product good enough that you would buy it again?” And the results are …
Good for Oracle in the US but the results do not fully reflect what’s on the ground here in Malaysia, which is more likely dominated by NetApp, HP, EMC and IBM.
I like the way Amazon is building their Cloud Computing services. Amazon Web Services (AWS) is certainly on track to become the most powerful Cloud Computing company in the world. In fact, AWS might already is. But they are certainly not resting on their laurels when they launched 2 new services in as many weeks – Amazon DynamoDB (last week) and Amazon Storage Gateway (this week).
I am particularly interested in the Amazon Storage Gateway, because it is addressing one of the biggest fears of Cloud Computing head-on. A lot of large corporations are still adamant to keep their data on-premise where it is private and secure. Many large corporations are still very skeptical about it even though Cloud Computing is changing the IT landscape in a massive way. The barrier to entry for large corporations is not something easy, but Amazon is adapting to get more IT divisions and departments to try out Cloud Computing in a less disruptive way.
The new service, is really about data storage and data backup for large corporations. This is important because large corporations have plenty of requirements for data storage and data to be backed up. And as we know, a large portion of the data stored does not need to be transactional or to be accessed frequently. This set of data is usually less frequently used, for archiving or regulatory compliance reasons, particular in the banking and healthcare industry.
In the data backup operations, the reason data is backed up is to provide a data recovery mechanism when a disaster strikes. Large corporations back up tons of data every day, weeks or month and this data only has value when there is a situation that requires data relevance, data immediacy or data recovery. Otherwise, it is just plenty of data taking up storage space, be it on disk or on tape.
Both data storage and data backup cost a lot of money, both CAPEX and OPEX. In CAPEX, you are constantly pressured to buy more storage to store the ever growing data. This leads to greater management and administration costs, both contributing heavily into OPEX costs. And I have not included the OPEX costs of floor space, power and cooling, people (training, salary, time and so on) typically adding up to 3-5x the operations costs relative to the capital investments. Such a model of IT operations related to storage cannot continue forever, and storage in the Cloud offers an alternative.
These 2 scenarios – data storage and data backup – are exactly the type of market AWS is targeting. In order to simplify and pacify large corporations, AWS introduced the Amazon Storage Gateway, that eases the large corporations to take some of their IT storage operations to the Cloud in the form of Amazon S3.
The video below shows the Amazon Storage Gateway:
The Amazon Storage Gateway is a piece of software “appliance” that is installed on-premise in the large corporation’s data center. It seamlessly integrates into the LAN and provides a SSL (Secure Socket Layer) connection to the Amazon S3. The data being transferred to the S3 is also encrypted with AES (Advanced Encryption Standard) 256-bit. Both SSL and AES-256 can give customers a sense of security and AWS claims that the implementation meets the data storage and data recovery standards used in the banking and healthcare industries.
The data storage and backup service regularly protects the customer’s data in snapshots, and giving the customer a rapid recovery platform should the customer experienced on-premise data corruption or data disruption. At the same time, the snapshot copies in the Amazon S3 can also be uploaded into Amazon EBS (Elastic Block Store) and testing or development environments can be evaluated and testing with Amazon EC2 (Elastic Compute Cloud). The simplicity of sharing and combining different Amazon services will no doubt, give customers a peace of mind, easing their adoption of Cloud Computing with AWS.
This new service starts with a 60-day free trial and moving on to a USD$125.00 (about Malaysian Ringgit $400.00) per gateway per month subscription fee. The data storage (inclusive of the backup service), costs only 14 cents per gigabyte per month. For 1TB of data, that is approximately MYR$450 per month. Therefore, minus the initial setup costs, that comes to a total of MYR$850 per month, slightly over MYR$10,000 per year.
At this point, I like to relate an experience I had a year ago when implementing a so-called private cloud for an oil-and-gas customers in KL. They were using the HP EVS (Electronic Vaulting Service) to an undisclosed HP data center hosting site in the Klang Valley. The HP EVS, which was an OEM of Asigra, was not an easy solution to implement but what was more perplexing was the fact that the customer had a poor understanding of what would be the objectives and their 5-year plan in keeping with the data protected.
When the first 3-4TB data storage and backup were almost used up, the customer asked for a quotation for an additional 1TB of the EVS solution. The subscription for 1TB was MYR$70,000 per year. That is 7x time more than the AWS MYR$10,000 per year cost! I have to salute the HP sales rep. It must have been a damn good convincing sell!
In the long run, the customer could be better off running their storage and backup on-premise with their HP EVA4400 and adding an additional of 1TB (and hiring another IT administrator) would have cost a whole lot less.
Amazon Web Services has already operating in Singapore for the past 2 years, and I am sure they are eyeing Malaysia as their regional market. Unless and until Malaysian companies offering Cloud Services know to use economies-of-scale to capitalize the Cloud Computing market, AWS is always going to be a big threat to CSP companies in Malaysia and a boon of any companies seeking cloud computing services anywhere in the world.
I urge customers in Malaysia to start questioning their so-called Cloud Service Providers if they can do what AWS is doing. I have low confidence of what the most local “cloud computing” companies can deliver right now. I hope they stop window dressing their service offerings and start giving real cloud computing services to customers. And for customers, you must continue to research and find out more which cloud services meet your business objectives. Don’t be flashed by the fancy jargons or technical idealism thrown at you. Always, always find out more because your business cost is at stake. Don’t be like the customer who paid MYR$70,000 for 1TB per year.
AWS is always innovating and the Amazon Storage Gateway is just another easy-to-adopt step in their quest for world domination.
Just after IDC released their numbers of their worldwide Disk Storage System Tracker (Read my blog) 10 days ago, Gartner released their Worldwide External Controller Based (ECB) Disk Storage Market report for Q3 of 2011.
The storage market remains resilient (for now) and growing 10.4% in terms of revenue, despite the hard economic conditions. The table below shows the top 7 storage vendors and their relation to their Q2 numbers.
EMC remained at the top and gained a massive 3.6% jump in market share. Looks like they are firing all cylinders and chugging like an unstoppable steam train. IBM gained 0.1% in second place as its stable of DS8000, XIV and Storewize V7000 is taking shape. Even though IBM has been holding steadily, I still think that their present storage lineup is staggered and lacks that seamless upgrade path for their customers.
NetApp, which I always terms as the “little engine that could”, is slowing down. They were badly hit in the last quarter, delivering lower than expected revenue numbers according to the analysts. Their stock took a tumble too. As quoted by Gartner, “NetApp’s third-quarter results reflect an overdependence on a few large customers, limited geographic coverage in high-growth countries and increased competition from Dell, EMC, HP and IBM in the midrange modular ECB disk array market segment.“
I wrote in my recent blog, that NetApp has to start evolving from a pure-play storage vendor into a total storage and data management solution vendor. The recent rumours of NetApp’s interests in Commvault and Quantum should make a lot of sense if NetApp decides to make that move. Come on, NetApp! What are you waiting for?
HP came back strong in this report. They are in 4th place with 10.4% market share and hot on NetApp’s heels. After many months of nonsensical madness – Leo Apotheker firing, trying to ditch the PC business, the killing of WebOS tablet, the very public Oracle-HP spat – things are beginning to settle a bit under their new CEO, Meg Whitman. In a recent HP Discover conference in Vienna, it was reported that the HP storage team is gung-ho of what they have in their arsenal right now. They called it “The 4 Jewels of HP Storage Crown” which includes 3PAR, Ibrix, StoreOnce and LeftHand. They also leap-frogged over HDS and Dell in the recent Gartner Magic Quadrant (See below).
Kudos to HP and team.
HDS seems to be doing well, and so is Dell. But the Gartner numbers tell a different story. HDS, lost market share and now shares 7.8% market share with Dell. Dell, despite its strong marketing on Compellent, could not make up its loss after breaking off with EMC.
Fujitsu and Oracle completes the line up.
My conclusion: HP and IBM are coming back; EMC is well and far ahead of everyone else; NetApp has to evolve; Dell still lacking in enterprise storage savviness despite having good technology; No comments about HDS.
It’s that time of the year again where Gartner releases it Magic Quadrant for the block-access, external controller-based, mid-range and high-end modular disk arrays market. This particular is very important because it represents the mainstay of the overall storage industry, viewed from a more qualitative angle. Whereas the other charts and reports work with statistics and numbers, this is the chart that everyone in the industry flock to. Gartner Magic Quadrant (MQ) is the storage industry indicator of who’s are the leaders; who are the visionaries; who are the executive wizards and who are the laggards (also known as niche players).
So, this time around, who’s in the Leaders Quadrant?
The perennial players in the Leader’s Quadrant are EMC, IBM, NetApp, HP, Dell, and HDS. In my previous blog, I shared with you the IDC figures about market shares but the Gartner MQ shows are more subtle side, and one that perhaps carry more weight to organizations.
From the IDC numbers announced previously, we have seen Dell taking a beating. They have lost market share and similarly in this latest Gartner MQ, they have lost their significance of their influence as well. Everyone expected their Compellent solution to be robust and having EqualLogic, Ocarina and Exanet in its stable would strengthen their presence in the storage industry. Surprisingly, Dell lost on both IDC statistically charged market numbers and this Gartner MQ as well. Perhaps they were too hasty to dump EMC a few months ago?
Gartner also reported that HP has made significant leap in the Leader’s Quadrant. It has leapfrogged over HDS and IBM when comparing their position in Gartner’s MQ chart. This could be coming from their concerted effort to pitch their Converged Infrastructure, a vision that in my opinion, simplified computing. HP Malaysia shared with me their vision a few months ago, and I was impressed. What I was not very impressed then and even now, is that their storage solutions story is still staggered, lacking the gel. Perhaps it is work in progress for HP, the 3PAR, the IBRIX and the EVA. But one things for sure. They are slowly but surely getting the StoreOnce story right and that’s good news for customers. I did a review of HP StoreOnce technology a few months ago.
Perhaps it’s time for HP to ditch their VLS deduplication, which to me, confuses customers. By the way, HP VLS is an OEM from Sepaton. (Sepaton is “No tapes” spelled backwards)
Here’s a glimpse of last year’s Magic Quadrant.
In the Niche Quadrant, there are a few players making waves as well. 2 companies to watch out for are Huawei (they dropped Symantec 2 weeks ago) and Nexsan. Nexsan has been beefing up its marketing of late, and I often see them in mailing lists and ads on some websites I went to.
But the one to watch will be Huawei. This is a company with deep pockets, hiring the best in the storage industry and also has a very strong domestic market in China. In the next 2-3 years, Huawei could emerge as a strong contender to the big boys. So watch out!
Gartner Magic Quadrant is indeed weaving its magic and this time around the magic is good to HP.
The storage train is still chugging hard and fast as IDC just released its Worldwide Disk Storage System Tracker for 3Q11. Despite the economic climate, the storage market posted a strong 8.5% revenue growth and a whopping 30.7% growth in terms of petabytes shipped. In total, 5,429PB were shipped in Q3.
So how did everyone do in this latest Tracker report?
In the Worldwide Total External Disk Storage Systems, EMC is still holding on to the #1 position, with 28.6%. IBM and NetApp came in at 12.7% and 12.1% respectively. The table below summarizes the percentage view of the top storage players, in terms of revenue.
From the table, everyone benefited from the strong buying of storage in the last quarter. EMC gained a strong market gain of almost 3%, while everyone else either gained or lost less than 1% market share. But the more interesting numbers are not from the market share column but the % growth column.
HDS posted the strongest growth of 22.1%, slightly higher than EMC of 22.0%. HDS is beginning to get their story right, putting the right storage solutions in place, and has been strongly focused in their services offering as well. That’s simply great news for HDS because this is a company is not known for their marketing and advertising. The Japanese “culture” within HDS probably has taught it to be prudent but to see HDS growing faster than the big boys like IBM and HP is something their competitors should respect. I believe customers are beginning to see the true potential of HDS.
As for EMC, everyone labels them as the 800-pound gorilla but they have been very nimble and strong in the storage market for many quarters. This is due to the strong management team headed by Joe Tucci and his heir-in-waiting, Pat Gelsinger. Several of their acquisitions are doing well, with the likes of Isilon, Greenplum, Data Domain, and of course VMware. Even though VMware does not contribute the EMC revenue numbers, the very fact that EMC owns more than 80% of VMware has already given EMC a lot of credibility in the storage battlefield. They are certainly going great guns.
NetApp took a hit in the last quarter, when they missed the street revenue numbers last quarter. Their stock took a beating and there were rumours in the market that NetApp might acquire Commvault and Quantum to compete with EMC. EMC has been able to leverage the list of companies and acquired solutions very well, from data protection solutions like Networker and Avamar, deduplication solutions like Data Domain and Avamar, Documentum for content management and so on, while NetApp has been, for the longest time, prefer a more “loosely-coupled” approach with their partners for a more complete solution set.
Other interesting reports from IDC are the Open SAN/NAS market, the NAS market and the iSCSI market.
The Open SAN/NAS market combination, according to IDC goes like this:
In the NAS only market, EMC and Isilon (under the one EMC umbrella) competes with NetApp and the table is like this:
The iSCSI only market is led by Dell (EqualLogic and Compellent combined), followed by EMC and IBM. Here’s the summarized table:
The strong growth is indeed good news as the storage market continues to weather the economic crisis storm. I have been saying this all along. The storage market in IT is still the growth engine as data keeps growing and growing, even though it was never the darling of the IT industry. Let’s hope the trend continues.
Europe is the worst hit region in this present economic crisis. We have seen countries such as Greece, Portugal and Ireland being some of the worst hit countries and Italy was just downgraded last week by S&P. Last week was also the release of the 2Q2011 External Disk Storage Systems figures from IDC and the poor economic sentiments are reflected in the IDC figures as well.
Overall, the factory revenue for Western Europe grew 6% compared to the year before, but declined 5% when compared to 1Q2011. As I was reading a summary of the report, 2 very interesting trends were clear.
- The high-end market of above USD250,000 AND the lower-end market of less than USD50,000 increased while the mid-end market of between USD50,000-100,000 price range declined
- Sentiments revealed that storage buyers are increasingly looking for platforms that are quick to deploy and easy to manage.
As older systems are refreshed, larger companies are definitely consolidating into larger, higher-end systems to support the consolidation of their businesses and operations. Fundamentals such as storage consolidation, centralized data protection, disaster recovery and server virtualization are likely to be the key initiatives by larger organization to cut operational costs and maximizing of storage economics. This has translated to the EMEA market spending more on the higher-end storage solutions from EMC, IBM, HDS and HP.
NetApp, which has been always very strong in the mid-end market, did well to increase their market share and factory revenue at IBM’s and HP’s expense because their sales were flattish. Dell, while transitioning from its partnership with EMC to its Dell Compellent boxes, was the worst hit.
The lower-end storage solution market, according to IDC figures, increased between 10-25% depending on the price ranges of USD5,000 to USD10,000 to USD15,000. This could mean a few things but the obvious call would be the economic situation of most Western European SMBs/SMEs. This could also mean that the mid-end market could be on the decline as many of the lower-end systems are good enough to do the job. One thing the economic crisis can teach us is to be very prudent with our spendings and I believe the Western European companies are taking the same path to control their costs and maximizing their investments.
The second trend was more interesting to me. The quote of “quick to deploy and easy to manage” is definitely pushing the market to react to more off-the-shelf and open components. From an HP stand point of their Converged Infrastructure, the x86 strategy for their storage solutions is making good sense, because I believe there will be lesser need for proprietary hardware from traditional storage vendors like EMC, NetApp and others (HP included). Likewise, having storage solutions such as VSA (Virtual Storage Appliance) and storage appliance software that runs on the x86 platforms such as Nexenta and Gluster could spell out the next wave in the storage networking industry. To have things easy, specialized appliances which I have spoke much of lately, hits the requirement of “quick to deploy and easy to manage” right on the dot.
The overall fundamentals of the external disk storage systems market remain strong. Below is the present standings in the EMEA market as reported by IDC.
I promised last week I will look deeper into HP StoreOnce technology and I did. As I mentioned in my previous blog, HP StoreOnce technology now embedded in its D2D series of secondary, target backup devices that does the job with no fuss and no fancy bells and whistles.
Here’s the lineup of the present HP D2D solutions.
HP Malaysia has constantly reminded me that their D2D deduplication solution is much more price competitive than their competitors and this is something you, the readers, have to find out on your own. But I do believe that they are. Unfortunately they did not have the first mover’s advantage when Data Domain took the industry by storm in 2009, since HP StoreOnce was only launched with much fanfare last year in June 2010. Despite that, there still plenty of room in the IT market to grow, especially in HP’s huge set of customers.
Without the first movers advantage, HP StoreOnce has to differentiate itself from the existing competitors such as EMC Data Domain and Quantum. Labeling their deduplication technology as version 2.0 (whereas the competitors are still at “Version 1.0″?), HP StoreOnce banks on 3 key technologies. They are
- Sparse Indexing
- Intelligent Block Size Management
- Reduction in Disk Fragmentation
Out of these 3, sparse indexing is the most interesting but I will save the best from last. Let’s start with Intelligent Block Size Management.
HP StoreOnce uses a variable chunking method with a smaller granularity of 4K in size and this is managed intelligently, thus achieving a higher deduplication ratio compared to its competitors which either uses a fixed chunking method or with a variable chunking method of larger block sizes in the range of 8K to 32K. The HP Lab’s testing reveals that the space savings was significant when compared with others.
Below are a set of results for a PowerPoint presentation and you can see for yourself.
(NOTE: Please note that the savings/deduplication ratio can be very different and can range from good to bad for different types of data. Video and images files are highly encoded. Seismic and geo-mapping files are highly compressed. It is very likely that most deduplication solutions cannot achieve a high percentage with these types of files)
Point #2 talks about Reduction in Disk Fragmentation. The inherent benefits from Intelligent Block Size Management brings about the Reduction in Disk Fragmentation. The smaller chunks means lesser space wastage, especially when the block size is 4K or lower. HP StoreOnce also uses an intelligent algorithm to place the blocks that are perceived to be related close to one another. Hence this “locality” presence helps and the retrieval and restore process will be faster and more efficient.
Sparse Indexing is where HP StoreOnce touts to be a game changer. Today’s data is already as massive as a mountain, and it’s going to get bigger and growing faster. Using “Version 1.0″ type of deduplication, the hashes created are stored in either memory or on disks. However, the massive data sets (especially unstructured data) are already producing massive amounts of hashes. Hashes are used to identify unique data blocks but the avalanche of unstructured data means that most deduplication solutions are generating more and more hashes, making most Version 1.0s hashes sluggish and difficult to retrieve.
Sparse Indexing addresses this hash problem (by the way, HP StoreOnce uses SHA-1 hash) by intelligently sampling a small chunks and creating a very fast index lookup mechanism that stays in the system’s memory all the time. As the engineers at HP Labs put it
Instead of holding every index item in RAM ready for comparison, the HP team keeps just one in every hundred or so items in RAM and puts the rest onto a hard drive. Duplicate data almost always arrives in bursts. In other words, if one chunk of the arriving stream is a duplicate, it is very likely that many following chunks are duplicates. Sparse indexing takes advantage of this phenomenon by storing the sequence of hashes of the stored chunks next to each other on disk. As a result, a ‘hit’ in the sample RAM index can direct the system to an area of the disk where many duplicates are likely to be found.
Sparse Indexing is not unique in the industry, but the engineers at HP Labs have put their thinking hats on and applied it to improve the search and looking up of the hashes in the StoreOnce deduplication technology.
Further savings are also achieved when the deduped data is compressed with the LZ (Lempel-Ziv) compression method before it is stored into the disks.
The HP StoreOnce technology is 100% fully concocted in the renown HP Labs and according to sources, this technology will indeed permeate across all HP StorageWorks (HP has since renamed it to HP Storage) line. With this strategy, HP hopes to address the “fragmented and complicated” (as quoted by HP) deduplication and data protection strategy across the enterprise. By “fragmented and complicated”, they mean that the deduplicated data constant has to be rehydrated and deduped again as the data moves across different IT devices and functions.
In a perfect world, HP wants their StoreOnce technology to be like the diagram below.
However, one very interesting fact that I found was HP does not believe that primary storage deduplication is a good idea. They claim that it complicates the whole thing. Whether HP likes it or not, NetApp has been dishing out primary storage deduplication for several years now and you don’t see their customers unhappy with NetApp about this feature.
In one of the HP Business whitepapers I read, one of the takeaways was
I was like, “Whoa! What’s this?”. I felt bemused about what was mentioned in the whitepaper. After all the best claims of the HP StoreOnce technology, I can’t help but to think that this could be a banana skin on the pavement for HP.
Compute and storage are 2 components within the IT infrastructure which are surely converging. SAN and NAS are facing their greatest adversary yet, and could be made insignificant if the cloud and virtualization game had their way. This is giving rise to the a new breed of solution, a specialized appliance where both compute and storage are ONE. Rising from the ashes of shared storage (SAN and NAS, take note), we are beginning to see things going back to way of direct, internal storage.
There were some scuffles in the bushes about 5 years, where Sun (now Oracle) was ahead of its game. The Sun Fire X4500 (aka Thumper) was one of the strong candidates to challenge the SAN/NAS duopoly in this networked storage period. X4500 integrated both the server and the storage components together, using ZFS as a file system and volume manager to deliver a very high throughput on all the JBOD disks very efficiently. ZFS acted as the RAID, so there was no need to have specialized RAID hardware. This proved that a very high performance storage solution can be easily integrated using standard off-the-shelf infrastructure components and the x86 architecture. By combining both compute and storage together, there were hints that the industry was about to rise up to Direct-Attached Storage (DAS) again, despite its perceived weakness against SAN and NAS.
Unfortunately, the applications were not ready for DAS then. Besides ZFS, applications such as databases, emails and file servers were not ready to jump into the DAS bandwagon and watch them ride into the sunset. But the fairy tale seems to be retold again, and this time, the evidence that DAS could rise again is much stronger.
The catalyst to this disruptive force? Virtualization!
I mentioned that VMware is the silent storage killer a few blogs ago. Needless to say, that ruffled a few featheres among the readers. I have no doubt that virtualization is changing how we storage guys look at SAN and NAS. In a traditional setup, the SAN or NAS is setup to provision LUNs or mount points to the data storage for VMFS volumes in the VMware environment. It will then be the storage array to provide snapshots, replications, thin provisioning and so on.
Perhaps VMware is nit picking that managing storage arrays for VMFS volumes is difficult. From the VMware administrators view, they are right. They don’t want to know what’s going on below the VM-level. All they want is storage, any kind of storage and VMware will manage the volumes, snapshots, replication and thin provisioning. Indeed they were already doing that since vStorage API was introduced. In the new release of VMware version 5.0, the ante has been upped even higher, making networked storage less and less significant.
If you want to know about vStorage API and stuff, below is a diagram of the integration of the various components at the VMware API level.
VMware can now use direct, internal storage look like shared storage. The Virtual Storage Appliance (VSA) does just that. VMware already has a thriving market from the community and hobbists for VMware Appliances.
The appliance market has now evolved into new infrastructure too. Using x86 architecture, off-the-shelf infrastructure components (sounds familiar?), companies such as Nutanix and Tintri are taking advantage of this booming trend to introduce specialized VMware appliances as shown in their advertisements on their respective web sites.
Here’s the Nutanix Ad:
Here’s the Tintri Ad:
Both Tintri and Nutanix are a new breed of appliances – specialized appliances for VMware.
At the same time, other applications are building these specialized appliances as well. I have mentioned Oracle Exadata many times in the past and Oracle Exadata is the perfect example an a fine-tuned, hardcore database engine to make the Oracle run at the best performance possible.
Likewise HP has announced their E5000 Messaging System for Microsoft Exchange. The E5000 is a specialized appliance optimized and well-tuned for the Microsoft Exchange Server 2010. From the words of HP,
“HP E5000 Messaging System is the industry’s first fully self-contained platform built for the next-generation of Microsoft Exchange to deliver enterprise-class messaging to businesses of all sizes. Built as a turnkey solution that can be up and running in a few hours vs. days, the HP E5000 Messaging System gives business users the experience they want most: large mailboxes, centralized archiving of mailboxes files and 24×7 access from any device. IT staffs benefit the solutions simplicity to setup, scale and manage and to meet new demands affordably. Ideal for multi-site enterprises as well as branch office and remote office environments, each HP Messaging System delivers greater simplicity and accelerates deployment with preconfigured solutions starting at 500 mailboxes up to 3000 mailboxes, while delivering large, 1 to 2.5GB mailbox sizes. Clients can grow by adding storage capacity or more appliances within the environment up from hundreds to thousands of mailboxes.”
What are the specs of this E5000 box, you say? Here you go:
And look at Row#2 in the table above … Direct, Internal Disks! Look at Row #4, Xeon CPUs! Both Compute and Storage in the same appliance!
While the HP E5000 announcement was recently, Hitachi Data Systems were already in the game early with their Unified Compute Platform and their Converged Platform for Microsoft Exchange with relatively the same idea – specialized appliances.
Perhaps the HDS solutions aren’t exactly direct, internal storage but the concept is still the same – specialized appliance. HDS Unified Compute Platform (UCP) has these components.
HDS Converged Platform for MS Exchange provides their specialized “appliance” with Reference Architectures that can support up to 68,000 Microsoft Exchange mailboxes. Here’s an architecture diagram of their “appliance”
There’s no denying that the networked storage landscape is changing. So are the computing platforms. We are already seeing the compute and storage components being integrated together, tighter than ever. The wave is rising for specialized appliances and it can only get more intense from now on.
No wonder HP’s Converged Infrastructure vision is betting on x86 architecture, simple storage platforms with SAS/SATA disks and Virtualization. Other vendors are doing the same as well – Cisco, NetApp and VMware with their FlexPod solution and EMC with their VBlocks of VMware, Cisco and EMC Storage.
Hail to the Rise of the Specialized Appliance!
It is past midnight and I can’t sleep. I haven’t been sleeping well lately, so I thought I catch up with some US news. And lo and behold, another big one showed up on Google News.
HP has fired Leo Apotheker and appointed Meg Whitman, the former boss of EBay, to become the new CEO and President of HP. Leo Apotheker was on the job for about 10 months (Damn!). Such actions shake investors confidence and not good for the image of the company. If Leo Apotheker wasn’t the right guy, why take him in the first place?
Leo is responsible for HP’s purchase of Autonomous just a month ago and now, the HP vision and direction have to be realigned again.
Here’s one of the news from Reuters.
Wait! There’s more confidence shattering news. Excerpt from one of the online news:
HP has laid off hundreds of employees in its ill-fated foray into the mobile ecosystem. HP is trying to spin off its PC unit and, at the same time, find a home for its fast deteriorating mobile assets, having spent billions of dollars trying to break into phones and tablets ($1 billion+ to buy Palm, investments in the business and write off of inventory) and then yanking the cord approximately 60 days into the adventure.
It is not hard to write not so good news about HP. They keep making such discouraging news on their own.
When VMware 5.0 was launched last month, I heard the feature called Virtual Storage Appliance (VSA) was finally out and is now being offered as an SMB/SME “storage” solution. In my mind, alarm bells were ringing because in its own stealthy manner, VMware had just become a storage player.
What VMware is offering is “Hey! If you don’t have money to buy your enterprise storage array, don’t worry. Make your own shared storage with our very own VMware VSA“. VSA utilizes the internal disks of the ESX/ESXi host as its shared storage.
VSA is nothing new. For years, LeftHand Networks had one for its engineers to do demo and show the functionality of their solution. EMC had it too, and recently I found out that NetApp has its own VSA, but only resell through its partner, Fujitsu. I am not 100% sure about the NetApp thing and I need a NetApp guy to verify this.
Smaller players, but not insignificant, such as Nutanix, Nexenta and Tintri are already offering their own versions and implementation of VSA to their customers, each with its own uniqueness and differences. With the release of the VMware VSA into the open, we shall see all the big storage players offering their VSAs to VMware, like natives offering sacrifices to VMware God. Or perhaps, it has already begun. It is ala-Nexus 1000v all over again.
VMware has become a huge juggernaut and it is merely using its advantage to consolidate the storage component under its control. When VMware version 4.0 came out, vStorage API was introduced along with VAAI (vStorage API for Array Integration). VAAI was created to enhance the storage experience by offloading specific storage operations to the native features of that supported storage platform. That’s all I know about VAAI at this moment, but with this feature, the storage array is tightly integrating its platform to VMware, or should I say … quietly ensnared by VMware tentacles of doom! (Evil laugh in the background! Mua ha ha ha ….!)
In the recently past VMworld, this storage story is slowly being unfurled even more to the world. VASA (vStorage API for Storage Awareness) was recently announced and EMC’s COO Pat Gelsinger spoke about the tighter integration (that word again!) that blurs the administration domain of the VMware admin and the storage admin. Below is a video of Pat Gelsinger talking about VASA below (this is long 55 minute video – Click only if you have the time).
Mind you, the entire vStorage API is still evolving as VMware 5.0 rolls out but here’s the thing. VMware has come out and say that the storage world about LUNs, RAID groups and mount points are a level below what the VMware admin should be concerned about. VMware admins handles their storage at the VM level or as VMDK and therefore, anything below it is of little significance to them. Again, you can see that VMware is using its muscle to say “If you guys want to play, you have to play by my rules“.
So, some new announcements came out from VMworld for storage such as Capacity Pools, I/O Multiplexer, and Storage DRS (Storage Distributed Resource Management) and also an enhanced version (probably more storage resilient) SRM (Site Recovery Manager). All these are being managed at a level above the traditional storage admin level and VMware has said that the VMware admin would be able to carve out a VM volume with its own set of default storage properties, defined snapshot retentions, replication and perhaps even compression and deduplication. But all these will be happening at the VM volume or VMDK level, not a level below that.
Details are still sketchy at this point in time and we probably won’t see these GA until probably VMware version 6.0. But the inertia has been rocked quietly and the VMware storage momentum will gain strength as time passes by. We could see that VMware would just need JBOD (just a bunch of disks) because it has its own enterprise storage features through its vStorage APIs or its future storage specifications. We have seen it happening in VSA with VMware offering its own storage.
From the similar news, what surprised me was what was quoted as shown below.
The presenters said VMware developed the APIs with EMC, NetApp, Dell, IBM and Hewlett-Packard,but they began the session with a disclaimer that none of those vendors has committed to support the APIs in their arrays.
Why the hell would EMC, NetApp, Dell, IBM and HP do something like that?!! Don’t they know that this could contribute to their insignificance in the future?
I am still perplexed but as the whole thing is still evolving, VMware seems to be only obvious winner here.
