Virtualization configuration

  • This solution implements the following Dell EMC and VMware best practices to provide optimal performance for all Splunk Enterprise virtual machines running on VxRail:

    • Creates a vSphere HA cluster to provide a virtualized, high-availability Splunk Enterprise environment that is easy to use and is cost-effective
    • Uses a VMware Paravirtual SCSI controller to increase throughput with significant CPU utilization reduction
    • Uses a VMware VMXNET3 network adapter to optimize network performance
    • Installs VMware Tools in the guest operating system to improve VM performance
    • Sets VM advance parameters numa.vcpu.preferHT to true for enabling hyperthreading with NUMA in ESXi
