VDI-IOmark, A Storage Specific Benchmark For VDI, Announces First Publicly Available Results With Hitachi HNAS Platform

Tuesday, February 14th 2012

VDI-IOmark for VMware View Provides Real Workload Measurement and Cost of Ownership

Boulder, CO (PRWEB) February 14, 2012. VDI-IOmark releases the first public benchmark results with Hitachi Data Systems on their Hitachi NAS Platform (HNAS), powered by BlueArc®.  Recognizing data storage is a major success component for VDI deployments, and that there has been no easy way to validate storage performance except to build a proof of concept, the members of VDI-IOmark and Evaluator Group have worked closely to release a repeatable storage performance benchmark culminating in the first release with Hitachi Data Systems.

“This is the result of a lot of work from our clients and vendor partners, across North America and Asia,” said Russ Fellows, Senior Partner of Evaluator Group and architect of the VDI-IOmark. “This first set of many announced results will provide the end user community a standard measurement that realistic, attainable and predictable.”

“By announcing these results we are demonstrating the scale and price / performance of the Hitachi NAS Platform,” said Ravi Chalaka, vice president, Product and Solutions Marketing, Hitachi Data Systems. “Calibrated with other internal lab tests, the VDI-IOmark shows a defined cost per standard and heavy workload VDI user.”

The VDI-IOmark measures storage system performance using real VDI user workloads. It does not use simulations or synthetics to approximate.  The foundation members of VDI-IOmark have set benchmark criteria with the following performance values:

  • For the steady-state workload:
  • 80% of response times for I/O’s must not exceed 50ms
  • All storage must reside on the storage system under test
  • The value reported corresponds directly to actual users
  • For the boot workload:
    • There is no limit to maximum I/O response times
    • All boot operations must complete in less than 2 minutes
    • The value reported indicates the number of desktops able to boot

    Other reporting criteria include:

    • Storage system configuration and tested environment must be reported
    • All storage for measured VDI users must reside on the storage system tested
    • Total list price for storage system tested must be reported

    More information on Theory of Operation and the Hitachi NAS Platform results are available at the VDI-IOmark website or from Hitachi Data Systems, respectfully. VDI-IOmark for VMware View is available via license to end users, vendors and test labs.  End User license may be obtained free of charge for 30 days for internal evaluation.
