An administrator has an AHV cluster that is comprised of 4 nodes with the following configuration in each node:
CPU: 2 each 2.4GHz, 12 core -
Memory: 256GB -
Disk: 6 each 1.92 SSD -
A VM with 16 vCPUs and 96GB of RAM is being created on the cluster.
How should the administrator configure the VM to assure optimal performance?
Configuring the VM with 2 vNUMA nodes ensures that the virtual machine's CPU and memory are optimally aligned to take full advantage of the underlying physical NUMA architecture. This helps in reducing latency and improving performance by closely aligning vCPUs with the local memory nodes in each NUMA configuration. Given the size of the VM relative to the physical resources available, setting up vNUMA is crucial for achieving optimal performance.
