I've got a new install of ESXi 4.1 on an HP Proliant DL180 G6. I've spun up a few VM's, but I am seeing absurd latency in the disks, the read latency stays around 30 ms, and the write stays around 60 ms with Spikes into the 400-500+ range whenever one of these VM's are doing anything related to writing or reading anything but the smallest amount of data.
The storage is local and these are 7200 RPM SATA drives, and to make it worse, they're in a RAID 5, so, I was expecting to see some latency, but I believe what I'm experiencing is way higher than it should be. Is what I'm experiencing to be expected considering the disks I'm using or is there something I need to look at?
