    No CPU and Memory oversubscription  Cisco UC

    kopper27 Expert

      hi guys

       

      there's this project where Cisco Communications are needed and the requirements says:

      All VMs require a one to one mapping between virtual hardware and physical hardware


      Unified Communications Virtualization Sizing Guidelines - DocWiki


      so my question what is to assign let's say 2 physical cores to a VM?

      document say:

      • Must map 1 VM vCPU core to 1 physical CPU core.

      and what about VM vRAM to pRAM? using reservations or limits?

      document says:

      • Must map 1 GB of VM vRAM to 1 GB of physical RAM. Memory oversubscription is not supported for Cisco UC VMs.

       

      thanks a lot
