Microsoft Hyper-V on x3650 M5 (Type 8871)

2019-09-04, 16:01 PM

Hi

 

I set up a Hyper-V failover cluster with 6 Lenovo servers (x3650 M5 Type 8871).  All VMs (Windows and Linux) are running fine and they can Live Migrate to other hosts without a problem.  However, the VM is running very slow.  The VM performance is very bad running on these servers environment.  Any idea or suggestion?

 

Thanks!

Chris

Hello Chris. While the fix outlined at the link below is for VMware servers, it may help with Hyper-V, as well.

Chris,

 

HW resources make a different: number of CPU/cores, memory, number of drives, RAID level, drive types, RAID controller model, RAID volume policies . . . will be a factor on performance.

It's advised to update the IMM and uEFI to latest version on 8871 systems to avoid potential problems. Then check the operating mode in uEFI setting, make sure the P-state, C-state are all enabled, and the operating mode is the max performance.

The Lenovo Server firmware has been upgraded to the latest version (TCE140D / 2.90 (Feb 12, 2019).   

The CPU P-state Control and C-States are set to none by default.  

 

I just change the CPU P-state Control and C-States to "Autonomous".  Power.PlatformControlledType=Maximum Performance.  I will move some VM into this server and see if it helps the performance.

 

Will update back soon.

 

Thanks!

Chris

Chris,


16GB of RAM for a server with VMs may be on the weak side. The memory needs to be shared between VMs and the host, and there may be some copetition for that limted resource.
On the storage side, RAID 1 or 10 is usually the best alternative for virtual environments; RAID 5 will slow things down, particularly if there is no cache on the RAID controller or it is not used.
In general, more drives on a RAID volume tend to offer better performance.
