Toshiba Memory Achieves VMware vSAN Certification for Value SAS SSDs

New Class of 12Gb/s RM5 Series Value SAS SSDs Approved for vSAN 6.7 Customers; Verified for Flash Storage Compatibility with Dell Server Platforms

SAN JOSE, Calif., June 5, 2019 – Toshiba Memory America, Inc. (TMA), the U.S.-based subsidiary of Toshiba Memory Corporation, today announced that its newly released RM5 Series of value SAS SSDs has earned VMware vSAN™ 6.7 certification running in Dell EMC PowerEdge servers. Designed to replace enterprise SATA SSDs in server applications, the RM5 Series delivers more than twice the performance per dollar1 of SATA SSDs at a similar price point. This certification enables 12 gigabits per second (12Gb/s) RM5 Series SSDs to be shared across connected hosts in a VMware vSphere® cluster, allowing users to pool SSDs together in a single, distributed shared data store.

VMware vSAN 6.7 certification is the most current vSAN compatibility with server-side support for Dell PowerEdge servers. Users can now have high confidence that Toshiba Memory’s RM5 Series SSDs will operate optimally on leading server platforms running a vSAN solution. These SSDs deliver faster, lower latency storage performance versus enterprise SATA SSDs, as validated through benchmark testing2. The results showcase that a vSAN cluster configured with RM5 drives delivered up to 40 percent higher application performance in a TPC-C™-like workload environment.

“We are pleased to collaborate closely with Toshiba Memory America to certify a new class of SSD for the fast-growing hyper-converged infrastructure industry,” said Lee Caswell, vice president of products, Storage and Availability Business Unit, VMware. “Storage performance has never been more critical, especially now that VMware vSAN is certified for the highest-performance in-memory databases. Customers looking for higher value and better performing solutions than SATA can look to Toshiba Memory’s RM5 Series of 12Gb/s value SAS SSDs.”

“Achieving VMware certification provides our RM5 value SAS SSD customers with the value, performance and confidence they need when deploying a vSAN solution,” said Alvaro Toledo, vice president of SSD marketing and product planning, Toshiba Memory America, Inc. “Based on validation testing, our RM5 SSDs demonstrated 45 percent more orders per minute for every dollar3 than enterprise SATA SSDs – enabling customers to take advantage of this added value at a competitive price point.”

RM5 Series 12Gb/s value SAS SSDs with VMware vSAN 6.7 and VMware ESXi™ 6.7 certification are listed in the VMware Compatibility Guide4 and are now shipping through Dell EMC PowerEdge server sales.

2 System-level OLTP benchmarking conducted by Toshiba Memory America, Inc. included RM5 Series SSDs (960GB capacities) and enterprise SATA SSDS (960GB capacities), in an emulated OLTP environment. Results were based on three runs that tested average transactions per minute (tpm) and overall disk latency (microseconds). Read and write speed may vary, as well as latency, depending on the host device, read and write conditions, and benchmark programs. Toshiba Memory defines a gigabyte (GB) as 1,000,000,000 bytes. Sequential read and write performance, and latency, mentioned herein are reference data, and may vary from the RM5 product data in the datasheet.
