Storage for Virtualization on Flash? Yes.

Planning the storage arrangement for virtualization is one of the most critical steps in delivering the right performance level. Recently, I previewed a new storage solution that is a good fit for virtualization environments due to its use of flash media instead of traditional hard drives.

Nimbus Data's Sustainable Storage is a flash-storage-based storage area network. Flash-based SANs have been available for a while, but Nimbus is priced competitively with traditional disk solutions using "spinning rust." The S-class storage systems start at $25,000 for flash storage solutions accessible via 10 Gb Ethernet.

Using flash-based storage systems in a virtualized environment is not new. In fact,  Microsoft's Hyper-V news earlier in the year about achieving over one million IOPs using its iSCSI initiator was performed on a flash SAN.

The Nimbus solution offers a number of opportunities for Ethernet-based storage protocols in and out of virtualization. This includes iSCSI, CIFS and NFS support. The iSCSI support is important so VMware environments can utilize the VMware VMFS filesystem for block-based access. VMware folks will quicky run off to the  hardware compatibility guide to look up this Nimbus product. During a briefing I received on the product, that was the question I asked and the answer is that Nimbus is working on the integration with VMware to officially be a supported storage configuration. Hyper-V support is also available for the S-class flash storage systems.

The advertised performance on flash-based storage is simply mind-boggling. Nimbus is cable of delivering 1.35 Million IOPs and 41 Gb/s throughput. With competitive pricing on this storage product, does this sound interesting for your virtualization environment? Share your comments here.

Nismo:

No one other than tech companies are reporting 1 M IOPs because people aren't doing it and don't care as long as its really good.

The Microsoft test had a RAM storage via the target, it wasn't Nimbus, but I am not sure what it was. If it was a StarWinds target, that's fine, but mind you that it is possible to put the RAM of a server to use as an iSCSI target as a virtual SSD/flash. The documentation of the Microsoft report can't confirm exactly what was performed, but if it was, that's fine as it is loosely equated to flash storage.

I'm not saying anything good or bad, I am just asking if anyone is doing it. I'm not doing this and I'm not going to jump into a storage product "that no one has heard of" on a whim. Why would I?

I don't agree with your assessment that I've screwed the facts. I'm just saying what is out there and I leave it to you to take it or leave it.

Hello Rick, Thanks for helping to bring validation to solid-state storage for virtualization environments. WhipTail Technologies has the Racerunner Virtual Desktop XLR8r with over 18 months of real customer production history. We also have referenceable customers doing 6,000 VDI users on a single Racerunner appliance. Our performance numbers (150,000 IOPS read, 100,000 IOPS write) are real "over-the-fabric" numbers and can prove it through customer references, and/or "try and buy" periods. We also work over Fibre Channel and InfiniBand (in addition to CIFS, NFS, Gig E and 10 GbE), so we can plug and play in just about any environment. Customers can also run different LUNs over different protocols with our unified LUN creation architecture. Also, our proprietary software stack manages write speeds and wear so that we guarantee 7+ years of durability of our drives, even with a FULL DAILY WRITE (VDI environments are up to 98% write!). We are Citrix certified and are in production with VMware and Microsoft. And finally, we offer true, inline data deduplication and compression on the fly - which is great for server virtualization environments and for portions of a VDI architecture. If you're serious about Flash Storage for VDI and want to work with a company that has integrity around our marketing numbers and can back up our claims, please email me or give me a call and we'll help you successfully deploy this initiative. All the best, Ryan Snell Regional Sales Manager North America 615-337-0883 rsnell@whiptailtech.com

Well... This article is full of screwed facts. First of all Microsoft & Intel had used StarWind Software iSCSI target and not anything else. Nimbus or whatever. Second they used RAM (Random Access Memory) rather then SSD during their 1M IOPs test. Third Nimbus CLAIMS they can overbeat 1M but nobody ever provided any tests. You can do it? No problem! You're welcomed to run the test and share results. But no answer... In a nutshell: don't be fooled by Numbus marketing. Some guys lost their jobs in 2003 and 2004 when TrueSAN (original company name for Nimbus) went out of business. They also promoted they are about to run a revolution... So are we here for the second round?
