Mate,
Long cpu waits time indicate:
- enabled power managemwnt of cpu/server in bios and in esxi
- some updates to server needed (hp maintenance cd) for whole server and p410
also recommend:
- for safety reason dont enable disk write cache for production env (if really bad things happens your whole VMFS datastores will crash)
- change chunk/cluster size of raid groups to 64kB (more iops, also hp p4xx series likes it, also vmware esxi like it)
- Check parameters in the bios, especially power management features like grater than c3 states (c3 is a max really working and supported by vmware for most cpu/servers)
- update vmware esxi to the newest
- update hp p410 drivers on vmware esxi
- maitain read/write ratio on p410 25/75% (in most cases works better)
