Lab Insight: IOmark-VM-HC Benchmark Report for Intel Servers and VMware vSAN Storage Software

Published August 16th, 2016. IOmark-VM-HC Benchmark Report for Intel Servers and VMware vSAN Storage Software.

This document is the official benchmark report for the tested configuration using Intel® S2600WT server platforms together with VMware Virtual SAN (vSAN) storage software as a hyper-converged system.

IOmark is a storage specific workload and benchmark designed to test storage systems performance using a variety of real world, application centric workloads. The IOmark-VM benchmark is a specific workload, which measures Server Virtualization workloads (VMs) run against storage systems. Results are published after audit and certified approval by IOmark authorized auditors.

IOmark-VM-HC is a benchmark that certifies Hyper-Converged systems for virtual server results. The measurement criteria are storage performance, with the restriction that all storage workloads must be supported by the tested Hyper-Converged system. Although there are CPU and memory considerations, these aspects are not tested by the IOmark-VM workload.

The results achieved by Intel hardware with VSAN SW running IOmark-VM are as follows:

  • A four-node cluster supported 320 IOmark-VM’s at a cost of $645.62 per VM
  • A six-node cluster supported 480 IOmark-VM’s at a cost of $545.27 per VM

A full description of the configurations tested along with pricing information is provided in this document. The criteria and performance requirements are as follows:

  • For all application workloads:
    • All workloads must reside entirely on the tested hyper-converged system
    • Workloads are scaled in sets of 8 workloads
    • 70% of response times for I/Os must not exceed 20ms
    • The average response time for each application type must not exceed 20ms
    • The execution time must complete within 1 hour and 15 seconds for each workload
  • For hypervisor operations:
    • Clone, deploy, boot, software upgrade, VM deletion
    • Storage migration (aka Storage vMotion) between storage volumes
  • For IOmark-HC benchmarks
    • The system CPU and memory must be sufficient to run the equivalent applications
    • The storage subsystem is measured by IOmark, with system CPU and memory compared to relevant published performance metrics
