So, I've updated all my storage for my ESXi server to SSD storage. I fitted it saturday afternoon and moved my 3 VMs to the new datastore on the SSD disk, just check out the looooooooooow disk latency.
Happy bunny?
... yes I am

Nice.
I've been using SSD on my PC at home, and it's made a huge difference, but I haven't had a chance to play with them in a server environment yet.

It is amazingly faster. It's just not the same at all.

Care to give any more information on the datastore? RAID level, HBAs, interconnects? Also, specifically what make and model of SSDs here? I'd think you're using something different from what GSquared has at home
Also, what's the link between the VMware server at the datastore, iSCSI target or something else?
Edit: Forgot the obvious... Thanks for sharing!

No RAID, no HBAs, no nuttink!
My VMFS datastore which sits under my 3 VMs is a single 240GB Corsair Force SATA3 disk.
The disk is a local SSD not iSCSI, but just look at the drop in latency

Wow, just freaking wow. All that with direct attached storage. You are a lucky son of a gun.

Just goes to show how performance is actually available. I'm sure there would still be increased latency if it were an iSCSI datastore, you have so much more in between that affects the performance.
Imagine a bunch of these sitting under your sql server files, it possibly wouldn't even matter too much if all files were on the same disks, latency is so low.
At SQLBits earlier this year i had a demo of the Fusion IO kit, amazing performance

Just make sure you have good backups. When SSDs fail, they can fail quickly with no warning.

I was wondering about this. Is there a RAID equivalent for SSD's?
