IOMARK Releases Virtual Machine Data Storage Benchmark Results for COHO DATASTREAM ALL-FLASH 2000f

Coho DataStream 2000f outperforms existing IOmark-VM results at 960 VMs at a cost of $302.08 per VM.

Boulder, CO (PRWEB) May 20, 2015. IOmark announces benchmark results for Coho Data DataStream 2000f, an addition to their family of web-scale storage solutions. IOmark-VM determined that a single chassis Coho Data 2000f system was able to support 448 virtual application workloads at a cost of $357.14 per VM and a two chassis 2000f was able to support 960 virtual applications at a cost of $302.08 per VM.

“The Coho DataStream All-Flash 2000f system delivered excellent performance, achieving an IOmark-VM level of 960. These are the highest certified results of any system we’ve tested to date,” said Russ Fellows, Senior Analyst at Evaluator Group. “Additionally, the scalability of the Coho architecture was evident with the 2 node system delivering more than 2X the performance of a single node system.”

The IOmark-VM tests real world workloads, measuring a standard set of applications running in a virtual environment. The results are audited to ensure uniform testing and reporting of results, enabling IT users the ability to compare products using metrics that matter, price, capacity and application performance. The application mix of IOmark-VM includes databases, webservers and Exchange mail servers, plus additional Hypervisor operations. Per the benchmark specifications, both the 1 and 2-node Coho DataStream 2000f configurations achieved these results with over 70% of response times below 20ms for all applications.

“Our mission at Coho Data has always been to build fast, flexible scale-out solutions that grow along with the needs of our customers, allowing them to focus on the demands of their business and not their datacenter solutions,” said Ramana Jonnala, Coho Data CEO and co-founder. “The 2000f DataStream solution allows Coho customers to add acceleration to their storage systems, without compromising the ease of use that comes with web-scale computing.”

Coho Data’s new all-flash 2000f DataStream combines Intel P3600 NVMe flash and conventional solid state drives to achieve performance results. DataStream 2000f can be deployed on its own or incorporated into existing Coho DataStream storage clusters while being managed from a single pane of glass.

The IOmark-VM workload measures storage system performance by recreating multiple instances of a standard set of virtual application, driving actual I/O streams rather than simulations or synthetic workloads. The IOmark-VM benchmark requires the following to achieve passing results:

For the steady-state workload:

  • Total test time is 1 hour, with a measured interval of 30 minutes
  • Seventy percent of response times for I/O’s must not exceed 20ms
  • A minimum number of storage vMotion and VM clone operations must also be completed during a 1 hour test

Other reporting criteria include:

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

Evaluator Group is the developer of IOmark which is available to end users or free to Evaluator Group IT end user premium subscribers Vendors, performance testing labs and channel partners may purchase to use the tool in their lab and for publishing audited results. Free evaluation licenses are available.

Coho results are available at the IOmark website. For more information on IOmark-VM see the IOmark Products.
