IOmark-VDI, a Storage Workload Specific Benchmark for VDI, Announces Results for Brocade’s 16Gb Fibre Channel Infrastructure and Nimbus Data’s Gemini Storage System

Nimbus demonstrates price performance of 4,032 VDI’s at an average cost of $39.68 per VDI running in a Brocade fibre channel environment.

Boulder, CO (PRWEB) September 25, 2013 – IOmark announces Nimbus Data benchmark results of the IOmark-VDI storage benchmark attaining 4,032 VDI’s for an average cost of $39.68 per VDI for Standard Workers. The IOmark-VDI tests real world application workloads for VMware View® with the output of audited, repeatable results. The benchmark is designed to provide comparative results for use in product selection.

The Nimbus Data benchmark was run in a Fibre Channel environment using Brocade Gen5 (16Gb), to maximize cost effectiveness. Surpassing benchmark specifications, the configuration delivered more than 90.1% of response times at less than 2ms, with 99.7% response time below 30ms.

“This is the first all Solid-State and Fibre Channel system with published results. Both the storage and Fibre Channel connectivity were important aspects in achieving performance required for this test,” said Russ Fellows, Senior Partner of Evaluator Group and architect of the IOmark. “The value of Flash coupled with 16 Gb Fibre Channel were clearly demonstrated with this real-world VDI environment.”

“By announcing these results we are demonstrating the scale and price / performance of the Nimbus Data Systems Gemini platform,” said Tom Isakovich, President, Nimbus Data. “VDI has been held back due to lack of performance and exceeding costs. With this real, repeatable benchmark, our customers can have the confidence to scale without

The IOmark-VDI measures storage system performance using real VDI user workloads. It does not use simulations or synthetics to approximate. The IOmark benchmark criteria have 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, light, standard and heavy workloads

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
