I have a C1100 with the following config:
- 2x L5520
- 72GB RAM
- 3 SSDs
- 1 HDD
Firmware Version 1.82.53138
BIOS Version S99C3B22
The system is surprisingly quiet and idles at 100 watts in ESXi low power profile and 150 watts in balanced power profile.
For my light VM usage, the low power profile make more sense, and that's what I am trying to use.
However, I have issues with ESXi freezing from time to time in that mode.
The error I get from IPMI every time it happens is: "PROC_IERR_STATUS: Processor sensor, IERR was asserted".
I don't get the issue in balanced power profile from testing over several days, but I might need to test further to confirm.
I have load tested the box by running several instance of y-cruncher - A Multi-Threaded Pi Program in a few VMs and maxing out the memory for hours.
The temps under load stay below 85C and stability is fine.
I have noticed the issue to arise in all cases thus far when the system is idle for a while and I execute a CPU intensive task in a VM thereafter.
It does not happen every time, but when it happens the above is the typical case that leads to it.
Right now, I have set ACPI to C2 and disabled C6 in the bios and currently waiting to see if it happens again.
Is anyone having similar experience under ESXi in low power profile or do I just have a faulty system?
Thanks.
