For my first day here, i want to share an odd experience.

We have so far, 2 HUS 110 and one HUS 150

All of them are showing very high latency spikes under quite "regular" stress.

The HUS 150 has got 144 300G 10K drives assigned to a HDP pool (RAID 10 3+3) and we are seeing 50+ ms spikes with only 2 non I/O intensive VM on it (the vcenter server and the HCS one).

Anyone has ever come across such issues ? (Servers are DELL + Emulex on the first HUS, the others are IBM 3850 with qlogic HBAS)

Thanks for helping.
