Anyone that has seen me present in the past two years has listened to me rant about the high cost of desktop virtualization and I did not hesitate to put the blame directly where it belonged: storage vendors. We’ve seen some crazy numbers at Gartner, upwards of $1000 per desktop for storage alone! Every time I hear that number I think of Seth and Amy on SNL doing the #Really skit.
$1000 for just the storage on 1 desktop!!!
Well the good news is that so long as you don’t blindly buy the storage some sales guy tells you to buy, chances are good you can solve VDI storage woes. In fact Citrix recently created a Citrix Ready VDI Capacity Validation Program for Storage Partners that I think has valuable information if your considering a VDI deployment.
Now I know this is a Citrix thing but here’s the deal; Desktops are desktops, storage is storage, and I don’t care if you use Citrix/VMware/Microsoft/Dell/Virtual Bridges/etc, If you are deploying thousands of virtual desktops, largely the overhead is due to Windows not due to the agent these VDI vendors run inside the VM. So with that in mind, take a look at the whitepapers they share. They provide detail for each storage vendor and they show LoginVSI tests (this is pretty much the de-facto standard in scale testing VDI environments) and they give details on the IOPS used and how much it cost.
For the lazy reader I created a comparison chart below, this is all public info that you can read yourself in the link above, I just consolidated the details I care about most, mainly price and performance.
*Please note: I did my best to make this accurate but I may have made a mistake (I’m human and this is just a blog not official Gartner research). If you see one let me know and I’ll update the graph. You can check all of these facts by reading the whitepapers yourself, if the mistake is in the whitepaper, tell the vendor. I noticed a few errors in the paper myself.
*The graph is sorted from least expensive to most expensive
