VMware ESXi

Each SANsymphony instance runs in a dedicated Windows guest virtual machine on the ESXi Host.

ESXi Host Settings

Host Server BIOS

Turbo Boost = Disabled

Although VMware recommend enabling this feature when tuning for ‘latency sensitive’ workloads, DataCore’s recommendation to disable will prevent disruption on the CPUs used by the SANsymphony virtual machine.

VMkernel

ISCSI VHMBA

‘Delayed ACK’ = ‘Disabled’

Via ‘vSphere Client → Advanced Settings → Delayed Ack’

Then uncheck both ‘inherit from parent’ and ‘DelayedAck’

 

A reboot of the ESXi host will be needed.
