Time for Change with Kit Colbert

Change is inevitable, it’s the only constant we have in life. Growth is optional. It is not necessary to change. Survival is not mandatory~ W Edwards Demming. To be able to handle change is the great differentiator. A company/person with the agility to see the change coming can adapt the quickest, one that has the change impact thrust upon it must respond, and that which can’t adapt will not survive. Change happens gradually, gradually – then suddenly. There is always a catalyst for change. Sometimes it’s a nice to have business need, other times it’s a hurricane that wipes out your entire business. The catalyst only determines the speed. Preparedness is essential in either situation.

Fault Resilient Memory (FRM) for Cisco UCS

We can see annual incidence of uncorrectable errors is rissing. Here is one possibility – How to solved it with FRM.

ESXi supports reliable memory.

Some systems have reliable memory, which is a part of memory that is less likely to have hardware memory errors than other parts of the memory in the system. If the hardware exposes information about the different levels of reliability, ESXi might be able to achieve higher system reliability.

How to enable in Cisco UCS

Configuration is in BIOS policy / Advanced / RAS Memory

8GB Could be enough for ESXi hypervisor …

This forces the Hypervisor and some core kernel processes to be mirrored between DIMMs so ESXi itself can survive the complete and total failure of a memory DIMM.

# esxcli hardware memory get
    Physical Memory: 540800864256 Bytes
    Reliable Memory: 8589934592 Bytes
    NUMA Node Count: 2 
#  esxcli system settings kernel list | grep useReliableMem
 useReliableMem Bool TRUE TRUE TRUE System is aware of reliable memory. 

Configuring Reliable Memory in Per-virtual machine basis (2146595)

I can decided to configure more Reliable Memory for VM – not only 8GB for hypervisor.

To turn on the feature per VM:

  1. Edit the .vmx file using a text editor
  2. Add the parameter:
    sched.mem.reliable = "True"
  3. Save and close the file

Conclusion:

  • For enable Fault Resilient Memory (FRM) I had to disable ADDDC Sparing in BIOS policy / Advanced / RAS Memory / Memory RAS configuration
  • With ADDDC and Proactive HA I can save about 95% failures – Personaly I prefer to use ADDDC
  • The Best possibility is to have both in future firmware …
