Nutanix AHV

Nutanix AHV Turbo for Windows now available.


Not so long back in time Nutanix announces a hot new unique feature in AOS 5.5 called Frodo, I mean AHV Turbo Mode, as the name suggest which key I press to enable turbo mode..

In general AHV present the single queue VirtIO-SCSI controller for VM’s, this controller can only submit 128 request at a time regardless of vCPU or number of disks.

In VMware vSphere world to get more IO throughput we used to add additional SCSI controllers and distribute disks across them, with the implementation of AHV Turbo Nutanix had introduced Frodo on AHV Host which bypasses QEMU and processes storage IOs as multi queue based on number of vCPU of VM.

The AHV Turbo mode is not a feature, rather native capability, for Linux guest VMs make sure you have Linux kernel supports (newer kernels do that by default) the blk_mq (block multiqueue) option, add the kernel parameter “scsi_mod.use_blk_mq=1” to enable blk_mq and remove the elevator=noop option.

With introduction to Nutanix VirtIO version 1.1.4 the same enhanced Storage IO throughput is now available for Windows guest VMs. For VMs having more than 2 vCPUs higher throughput might be observed after installing VirtIO 1.1.4.
