This section describes the memory optimization techniques you can use for low-memory servers (64 GB). If you use any additional packages or drivers that are not part of the VMware Telco Cloud Platform RAN Bundle of Materials (BOM), the server might consume more memory and you cannot power ON the VM requiring 52 GB memory on the server. You can reduce the memory consumption in the server by using memory optimization techniques and instantiate the 52 GB VM on the 64 GB server.

Note:

Telco Cloud Platform RAN provides memory optimization in the way the latest drivers/firmware and ESXi consume memory. Ensure that you use drivers as recommended in the BOM. For information about specific driver versions that are compatible with Telco Cloud Platform RAN releases, see KB87936.

Procedure

  1. Log in to the ESXi host as a root user.
  2. Run the following commands: 
    esxcli system settings kernel set -s maxVMs -v 6
esxcli system settings advanced set -o /Mem/MemMinFreePct -i 1
esxcfg-module -d irdman
  3. Reboot the ESXi host.
