PCI-E SSD
Currently our VDI setup is only used in the Library and so we very rarely max out the usage on our server, however ealier today I spotted that we had 19 of our 20 VDI clients in use, by in use thats students logged in actively engaging with their computers.
I couldn’t resist checking up on the performance stats and shall we say………WOW……….less than 0.4 on the disk que length at all times and the response time never went above 2ms during average use (about 12-36MB/s) and only hit 9ms when the IO bursted to 84MB/s!

Proving that PCI-E SSD works fine in standard servers (like the HP DL line) is a key goal of this series of posts, above you can see the PCI-E SSD churning away quite happily serving up virtual desktops.
One of the great things about VDI is the ability to create a ‘golden image’, that’s one single image that includes the OS and Software which can be accessed from any endpoint. Whatever VDI software you go with will then take that golden image and duplicate it multiple times to provide the desktops for your users.
However this masse creation of desktops can cause a bit of a IO overload…..one problem of many that a SSD can solve….
In this series I am going to be looking at how PCI-E SSDs can be used with VDI, I’ll be covering the hardware in use, the user experience and also why I believe PCI-E SSDs to be the best option to get your virtual desktops running as fast as possible. Continue reading
