BladeSystem Gen8 Severs and VMware question

VMware question from Jean-Yves:

 

***********

 

Hi Expert

 

One of my customer is facing an issue with ProLiant Gen 8 servers under Vmware ESXi. The VMs freeze from time to time

 

The solution is to deactivate in the BIOS the Energy Economy ! Is someone aware of that issue ?

 

Is there a Bios version that correct this bug?

 

Thanks for your help

Consider reading the Technical Whitepaper "Configuring and tuning HP ProLiant Servers for low-latency applications"

 

There are also various VMware guest settings that reduce the abstraction and make them closer to the hardware that could possibly lead to anomalies.

 

You could be having a problem related to changing of clock frequencies.

 

If your network adapters are high performance, there are numerous possibilities for packet skew that can hang a guest.

If you have a guest that is performing the backups of other servers, you should consider de-virtualizing it.

I seem to remember that you always wanted the BIOS settings to be set to "High Performance" and not use any power saving settings with VMware.

So..

 

How did you go with the case Chuck ?

 

Does the VMware vSphere using DPM to standby the server as well or just make all of those ESXi servers up and running using the highest performance BIOS power profile ?

 

I'm also curious to know it as well.
