The battle is probably already here. It has just begun for rack mounted flash-based or DRAM-based (or both) storage systems.
We have read in the news about the launch of EMC’s Project Lightning, and I wrote about it. EMC is already stirring up the competition, aiming its guns at FusionIO. Here’s a slide from EMC comparing their VFCache with FusionIO.
Not to be outdone, NetApp set its motion to douse the razzmatazz of EMC’s Lightning, announcing the future availability of their server-side flash software (no PCIe card) but it will work with major host-based/server-side PCIe Flash cards. (FusionIO, heads up). Ah, in Sun Tsu Art of War, this is called helping your buddy fight the bigger enemy.
NetApp threw some FUDs into the battle zone, claiming that EMC VFCache only supports 300GB while the NetApp flash software will support 2TB, NetApp multiprotocol, and VMware’s VMotion, DRS and HA. (something that VFCache does not support now).
The battle of PCIe has begun.
The next battle will be for the rackmounted flash storage systems or appliance. EMC is following it up with Project Thunder (because thunder comes after lightning), which is a flash-based storage system or appliance. Here’s a look at EMC’s preliminary information on Project Thunder.
And here’s how EMC is positioning different storage tiers in the following diagram below (courtesy of VirtualGeek), being glued together by EMC FAST (Fully Automated Storage Tiering) technology.
But EMC is not alone, as there are already several prominent start-ups out there, already offering flash-based, rackmount storage systems.
In the battle ring, there is Kaminario K2 with the SPEAR (Scale-out Performance Storage Architecture), Violin Memory with Violin Switched Memory (VXM) architecture, Purestorage Purity Operating Environment and SolidFire’s Element OS, just to name a few. Of course, we should never discount the grand daddy of all flash-based storage – Texas Memory Systems RamSAN.
The whole motion of competition in this new arena is starting all over again and it’s exciting for me. There is so much to learn about newer, more innovative architecture and I intend to share more of these players in the coming blog entries. It is time to take notice because the SSDs are dropping in price, FAST! And in 2012, I strongly believe that this is the next battle of the storage players, both established and start-ups.
Let the battle begin!
The Thailand flood last year spelled disaster to the storage industry. We have already seen several big boys in the likes of HP, EMC and NetApp announcing the rise of prices because of the flood.
But the Chinese character of “crisis” (below) also spells opportunities; opportunities for Solid State Drives (SSDs) that is.
For those of us close to the ground, the market for spinning hard disk drives (HDDs) has certainly been challenging for the past few months, especially for smaller system providers like us. Without the leveraging powers of the bigger boys, we practically had to beg to buy HDDs, not to mention the fact that the price has practically doubled.
Before the Thailand flood crisis, the GB/$ of a 2TB HDD was 0.325 Malaysian ringgit per GB. That’s about 33 cents. Today, the price is about 55 cents per GB. In comparison, at least from my experience, the GB/$ of SSDs has gone down from $5.83 to $4.99.
I know some of you might pooh-pooh the price difference between a 2TB SATA/SAS and a 120GB SSD, partly because the SSD seems so expensive. But when you consider that doing the math, the SSDs is likely to be 50x faster (at worst average) and 200x faster (at best average) for applications requiring IOPS, this could mean that transactional applications are likely to be completed an average of 100x faster, with better response time, with lower latency. This will have a domino effect on other related applications, making the entire service request performing and completing faster. When we put a price to the transactional hours, for example $10/hour work, then we can see the cost savings coming from using SSDs in the storage.
Interestingly, a friend of mine asked me about the prominence of an all SSDs storage systems. I have written about all SSDs systems in the past, and also did a high overview of Pure Storage some time back. And a very interesting fact I recalled was these systems having massive amount of IOPS. Having plenty of IOPS helps because you do away with Automated Storage Tiering (AST) because you don’t have to tier your data, and you don’t have to pay for such a feature.
Yes, all-SSDs pure-play storage systems are gaining prominence and it’s time to take notice. Nimbus beat NetApp and HP 3PAR last year to win eBay with an all SSDs storage solution and other players such as Violin Memory Systems, Pure Storage, SolidFire and of course, Texas Memory Systems (aka RAMSAN). And they are attracting big names into their management portfolios and getting VC dollars of course.
The Thailand flood aftermath will probably take 6 months or more to return to its previous production capacity prior to the crisis and SSDs can take this window of opportunity in the crisis to surge ahead. And if this flood is going to be an annual thing for Thailand (God bless Thailand), HDD market is going to have a perennial problem. And SSDs is going to rise even faster.
I have been receiving a lot of email updates from Texas Memory Systems for many months now. I am a subscriber to their updates and Texas Memory System is the grand daddy of flash and DRAM-based storage systems. They are not cheap but they are blazingly fast.
Lately, more and more vendors have been coming out with all SSDs storage arrays. Startups such Pure Storage, Violin Memory and Nimbus Data Systems have been pushing the envelope selling all SSDs storage arrays. A few days ago, EMC also announced their all SSDs storage array. As quoted, the new EMC VNX5500-F utilizes 2.5-in, single-level cell (SLC) NAND flash drives to 10 times the performance of the hard-drive based VNX arrays. And that is important because EMC has just become one of the earliest big gorillas to jump into the band wagon.
But does it make sense? Can one justify to invest in an all SSDs storage array?
At this point, especially in this part of the world, I predict that not many IT managers are willing to put their head on the chopping board and invest in an all SSDs storage array. They would become guinea pigs for a very expensive exercise and the state of the economy is not helping. Therefore the automatic storage tiering (AST) might stick better than having an all SSDs storage array. The cautious and prudent approach is less risky as I have mentioned in a past blog.
I wrote about Pure Storage in a previous blog and the notion that SSDs will offer plenty of IOPS and throughput. If the performance gain translates into higher productivity and getting the job done quicker, then I am all for SSDs. In fact, given the extra performance numbers
There is no denying that the fact that the industry is moving towards SSDs and it makes sense. That day will come in the near future but not now for customers in these part of the world.
