We currently have a HP DL320S 1.2TB Storage Server NAS that we are looking to replace. We purchased this NAS a year before even thinking about virtualizing and now that we have virtualized most of our corporate office we are finding the performance to be pretty crappy on this NAS as a central storage to the point that my virtual desktop users complain about delays and lag. (which I have pin pointed down to Long Physical Disk Queue's).
Right now we virtualize approx 10 servers and 10 desktops (not using View, we just have Wyse terminals that connect to XP RDP sessions directly). We have two ESX servers connecting to this NAS via NFS.
We are looking to make a change. I have a budget of around $14,000. I don't need a TON of storage space (2TB would be fine), I care more about IOPs & performance. Any suggestions? I am pretty happy with NFS and I hear that these days High End NAS's can compete with High End SAN's... any thoughts? I am not partial to any brands.
We are on ESXi 4.1
Any tips would be great. Thanks for you help.
