Storage Spaces can be used to virtualize storage and allow customers to deploy highly available, cost-effective and resilient storage solutions for all workloads.

Storage Spaces is capable of scaling to multi-million IOPS while satisfying the need for different workload types that will shape the behavior and configuration of a storage solution. Storage Spaces has parameters that can be fine-tuned toward workload needs in order to achieve optimal performance for a wide range of different applications, allowing customization toward specific business needs.

Microsoft has been able to achieve test lab performance results that deliver very compelling results. Below you will notice the Storage Spaces Certified hardware utilized to perform the Storage Spaces performance testing results.

  • 3x Intel Romley server nodes with Intel Xeon E5-2670 (2.9GHz) Processors
  • 2x DataON Storage DNS-1640 2U 24-bay JBODs
  • 4x LSI 9207-8e 6Gb/s SAS HBA per server node
  • 48x STEC 6Gb/s SAS MLC 400GB  SSD drives (9.6TB per JBOD)

The recent test-bed solution consisting  of three clustered server nodes with a single DNS-1640 2U 24-bay SSD JBOD achieved  1.45 million IOPS (Input/Output Operations per Second) with a sustained throughput over 12.6GB/s.

When adding a second DataON Storage DNS-1640 JBOD (48 STEC SAS SSDs total) to the storage pool Microsoft was able to achieve maximum performance of 2.7 Million IOPS and 20GB/s sustained throughput using a cost efficient storage solution in a fault tolerant configuration.

Microsoft test labs, Matt Garson discusses the performance testing achieved using the DataON Storage Microsoft-certified JBOD storage enclosures.


Storage Spaces, as a Software-defined Storage solution, significantly reduces the cost of highly-available, resilient, and scalable storage because it breaks free from the legacy storage concept of requiring a storage network and external SAN storage subsystem. Spaces is designed to work with cost efficient, industry standard commodity servers and integrate with certified OS-agnostic storage enclosures such as DataON Storage.  Storage Spaces integrates with other capabilities part of Windows Server 2012 to provide an incredibly cost-effective storage platform, at scale, and out-performs the performance needs of mission-critical deployments.

Your current web browser must be updated to version 7 of Internet Explorer (IE7) to take advantage of all of template's capabilities.

Why should I upgrade to Internet Explorer 7? Microsoft has redesigned Internet Explorer from the ground up, with better security, new capabilities, and a whole new interface. Many changes resulted from the feedback of millions of users who tested prerelease versions of the new browser. The most compelling reason to upgrade is the improved security. The Internet of today is not the Internet of five years ago. There are dangers that simply didn't exist back in 2001, when Internet Explorer 6 was released to the world. Internet Explorer 7 makes surfing the web fundamentally safer by offering greater protection against viruses, spyware, and other online risks.
