    Recommendations for Optimum Performance

    Following are recommended VMware ESXi and
    Spacevars
    0product2
    virtual machine (VM) configurations. 

    The following general recommendations apply to all platforms where SBC SWe is deployed:

    • The number of vCPUs deployed on a system should be an even number (4, 6, 8, etc.).
    • For best performance, deploy only a single instance on a single NUMA. Performance degradation occurs if you host more than one instance on a NUMA or if a single instance spans multiple NUMAs.
    • Make sure that the physical NICs associated with an instance are connected to the same NUMA/socket where the instance is hosted. In the case of a dual NUMA host, ideally two instances should be hosted, with each instance on a separate NUMA and the associated NICs of each of the instances connected to their respective NUMAs.
    • To optimize performance, configure memory card equally on both NUMA nodes. For example if a dual NUMA node server has a total of 128 GiB of RAM, configure 64 GiB of RAM on each NUMA node.

    General ESXi Recommendations

    Following The following are recommended recommendations for 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 Under BIOS settings, disconnect or disable any physical hardware devices (Floppy floppy devices, Network network interfaces, Storage storage controllers, Optical 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 when creating new VMs (available starting in ESXi 5.x). This provides additional capabilities to VMs such as supporting a VM with up to 1 TB RAM, up to 32 vCPUs, etc.

    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, but the number should be even (4, 6, 8, etc.) to avoid impacting performance.

    Keep the 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.

    WarningIn Direct I/O, if you want to notified with link detection failure using LinkMonitor, use a server with more than 4 vCPUs

    Refer to Adjusting Resource Allocations for a VM for more information on setting CPU-related parameters.

     vRAM

    Keep the Resource Allocation setting marked as 'unlimited'. Reserve the memory based on call capacity and configuration requirements. Refer to SBC SWe Performance Metrics for supported call capacities with different configuration limits.

    Virtual Hard Disk

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

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

        Info
        title
    note
      • 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
    Info
    titleNote

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


    Infonote
    titleNote

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