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:

Edit the .vmx file using a text editor
Add the parameter:
sched.mem.reliable = "True"
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 …

Upgrading NSX-T 3.1.2 Data Center

After you finish the prerequisites for upgrading, your next step is to update the upgrade coordinator to initiate the upgrade process.

Trending support issues in VMware NSX (2131154) – This article provides information regarding trending issues and important Knowledge Base articles regarding VMware NSX Data Center for vSphere 6.x and VMware NSX-T Data Center 3.x.

NSX-T 3.1.2 – Upgrade the Upgrade Coordinator – 1/4

The upgrade coordinator runs in the NSX Manager. It is a self-contained web application that orchestrates the upgrade process of hosts, NSX Edge cluster, NSX Controller cluster, and Management plane.

NSX-T 3.1.2 – Upgrade NSX Edge Cluster – 2/4

After the upgrade coordinator has been upgraded, based on your input, the upgrade coordinator updates the NSX Edge cluster, hosts, and the Management plane. Edge upgrade unit groups consist of NSX Edge nodes that are part of the same NSX Edge cluster. You can reorder Edge upgrade unit groups and enable or disable an Edge upgrade unit group from the upgrade sequence.

NSX-T 3.1.2 – Configuring and Upgrading Hosts 3/4

You can upgrade your hosts using the upgrade coordinator.

NSX-T 3.1.2 – Upgrade Management Plane – 4/4

The upgrade sequence upgrades the Management Plane at the end. When the Management Plane upgrade is in progress, avoid any configuration changes from any of the nodes.
