C H A P T E R 1 2 VMware ESX Server Resource Management
419
The system type indicates the hardware for your NUMA system (in this case, an IBM
x445 server). There are two NUMA nodes.
The fields in the table are defined as follows:
• Node — Node number
• ID — Hardware ID number of the NUMA node
• MachineMem — Amount of physical memory located on this NUMA node,
including memory that may be used by the service console.
• ManagedMem — Amount of physical memory located on this NUMA node,
excluding memory used by the service console and the ESX Server virtualization
layer.
• CPUs — A space-separated list of the physical processors in this node.
Physical CPUs 0, 1, 2, and 3 are in NUMA node 0, and physical CPUs 4, 5, 6, and 7
are in NUMA node 1.
Total memory tells you how much memory is physically installed on each NUMA
node. However not all of this memory may be managed by the VMkernel, as some of
the memory is used by the service console.
Determining the Amount of Memory for each NUMA Node
Type the following:
cat /proc/vmware/mem/
An example output is:
In this preceding example, the total memory managed by the VMkernel for the NUMA
nodes is listed in the Totals row. (This amount may be smaller than the total
amount of physical memory on the server machine.
Determining the Amount of Memory for a Virtual Machine on a NUMA Node
Type the following:
cat /proc/vmware/vm/<id>/mem/numa
