Evaluator Group Benchmark of Dot Hill AssuredSAN Pro 5000

Evaluator Group’s IOmark
announces Dot Hill Systems Corp
results of the IOmark-VM
storage benchmark (registration needed) supporting 240
simultaneous virtual applications, with an average cost of $509.42
per application instance.

It 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 such as capacity and application performance.

The system was run using the IOmark-VM
workload to measure performance and cost effectiveness of storage
systems. Per the benchmark specifications, the AssuredSAN Pro 5000
supported 240 applications, with a mean response time of 8.92ms.

"We have tested systems in our
labs with IOmark -VM, and this is an excellent price – performance
result, achieved due to the automated tiering capabilities of the Dot
Hill storage system," said Russ Fellows, senior partner,
Evaluator Group and
architect of the IOmark. "The AssuredSAN Pro 5000 well while
running the standard IOmark-VM application workload.  The Dot
Hill system automated tiering used a mixture of solid state and HDDs,
which contributed to the excellent price/ performance results."

"By announcing these results we
are demonstrating the scale and price / performance of the Dot Hill
Systems AssuredSAN platform," said Mike Jensen, principal
storage architect, Dot Hill. "In many cases, deployments of
virtual applications have been hampered by the fear of how
virtualization can impact application performance with traditional
storage systems.  The real-world results IOmark-VM provides,
enable IT users to architect virtual infrastructure and cloud
deployments with clarity of real-world price and performance levels."

IOmark-VM is designed for end user and
vendor test labs. The Dot Hill benchmark was accomplished utilizing a
server infrastructure that was 90% smaller than the equivalent
application workload running on leading servers.

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 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

• 70% of response times for I/O’s must
  not exceed 30ms

• 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
