    Sonus Recommendations for Optimum Performance

    Following are recommended VMware ESXi and

    Spacevars
    0product2
    virtual machine (VM) configurations. 

    General ESXi Recommendations

    Following are recommended VMware ESXi configurations:

    • Plan enough resources (RAM, CPU, NIC ports, hard disk, etc.) for all the virtual machines (VMs) to run on server platform, including resources needed by ESXi itself.
    • Allocate each VM only as much virtual hardware as that VM requires. Provisioning a VM with more resources than it requires can, in some cases, reduce the performance of that VM as well as other virtual machines sharing the same host.
    • Disconnect or disable any physical hardware devices (Floppy devices, Network interfaces, Storage controllers, Optical drives, USB controllers, etc.) under BIOS settings that you will not be using to free up interrupt/CPU resources.

    • Use virtual hardware version 8 and above while creating new VMs (available starting ESXi 5.x). This provides additional capabilities to VMs such as supporting VM with up to 1 TB RAM, up to 32 vCPUs etc.

    ...

    Use VMware vSphere client to configure the following ESXi host configuration parameters on the Advanced Settings page (see figure below) before installing the

    VM Configuration Recommendations

    Caption
    0Table
    1VM Configuration Recommendations
    SettingsRecommended Configuration
    vCPU

    Minimum 4 vCPUs required. But In case where there are only four physical cores available, you must configure the VM with only 3 vCPUs. Any number of vCPUs may be configured depending upon the call capacity requirements.

      • Keep Resource Allocation setting marked as 'unlimited' with CPU freq. set to "physical processor CPU speed multiplied by number of vCPUs assigned to VM".
    Note

    3 vCPUs configuration is supported only from SBC 4.2.4 release.

    Note

    VMDirectPath mode is only supported for PKT ports for vCPUs >=4.

    vRAM

    Keep Resource Allocation setting marked as 'unlimited'. Reserve the memory based on the VM capacity requirement. For lesser than 6K calls, the minimum reservation must be 8GB. Anything higher than 6K calls requires atleast 14 GB vRAM.

    Virtual Hard Disk

    Set Hard Disk (virtual) size as 100 GB or more (based on requirements of retaining CDRs, logs, etc. for number of days)

      • Use Thick provisioning (eager zero)
      • Hard disk size cannot be changed once SBC SWe software is installed
    vNICs

    Set number of virtual NICs as 4 (1-MGMT, 1-HA, 1-PKT0 and 1-PKT1).

    • Use only VMXNET3 driver
    • Always use automatic MAC address assignment option while creating vNICs.
    • Associate each vNIC to separate vSwitches
    • Use ESXi NIC teaming feature to achieve redundancy at physical NIC level.
    vSwitch settings
    • Use four different vSwitches for each vNICs on
      Spacevars
      0product
      VM. This ensures various traffic to be physically separated on SBC.

      • Assign 1 physical NIC port (1 Gbps) to each vSwitch if physical NIC redundancy is not needed, otherwise assign 2 physical NIC ports (in active-standby mode using NIC team feature) to each vSwitch.

        Note

        The same physical NIC port cannot be associated with different vSwitches.

    • Use four different virtual networking labels, each with different VLANs or subnets.
    • Always run active and standby
      Spacevars
      0product
      VMs on different physical servers
    • Disable VM logging
    Note

    Make sure the Processors, ESXi version and VM configuration (vCPUs, vRAMs, Virtual Hard Disk, vNICs, and vSwitch Settings) must be identical for SBC SWe HA pair.

    Note

    Make sure that the BIOS and ESXi settings and recommendations must not be changed once it is applied on the server.

    ...

    • -supported Intel processor meets the ESXi hardware requirements.
