New 12Gb/s PM5 Series Approved for vSAN 6.7 Customers; Ensures Flash
Storage Compatibility as Capacity or Caching
SAN JOSE, Calif.–(BUSINESS WIRE)–Toshiba
Memory America, Inc. (TMA), the U.S.-based subsidiary of Toshiba
Memory Corporation, today announced that its newly released PM5
Series of 12Gb/s (gigabits per second) enterprise SAS SSDs has
earned VMware vSAN™ 6.7 certification. This certification enables TMA’s
flash-based PM5 storage devices to be shared across connected hosts in a
VMware vSphere® cluster. With the vSAN 6.7 certification, users can pool
PM5 Series SSDs together in a single, distributed shared data store.
This allows users to define the storage capabilities required (such as
performance, capacity and availability) for each connected virtual
machine (VM) within the VMware vSAN cluster. These capabilities not only
further hyper-converged infrastructure (HCI) options in virtual
environments, but also ensure that storage policies are administered and
maintained within the PM5 Series with the utmost vSAN compatibility.
The certification of the PM5 Series enables VMware vSAN support for both
hybrid and all-flash configurations using a two-tier storage
architecture (capacity tier and cache tier). All write operations are
sent to the cache tier and are subsequently de-staged to the capacity
tier over time. When a PM5 Series SSD is deployed within a hybrid
configuration, its cache tier is used as both a read and write cache,
keeping hot data to improve performance. In an all-flash configuration,
100 percent of the cache tier is used for the write buffer. Given the
benefits of tiered storage, PM5 Series SSDs are capable of meeting the
demanding requirements of both enterprise and data center customers.
Built with Toshiba Memory Corporation’s 64-layer BiCS FLASH™ TLC
(3-bit-per-cell) 3D flash memory, the PM5 Series offers up to 15.36
terabyte1 (TB) capacities in a 2.5-inch form factor2,
and supports a full range of endurance and capacity ranges. It also
utilizes the industry’s first3 MultiLink SAS™ architecture,
which delivers the fastest4 SAS SSD sequential performance to
date5. In addition, PM5 Series SSDs support multi-stream
write technology – a feature that intelligently manages and groups data
types together to minimize write amplification and garbage collection.
This translates into reduced latency, improved endurance, increased
performance, and better Quality of Service (QoS).
“We are pleased to collaborate closely with Toshiba Memory America to
jointly certify flash innovations for the fast-growing hyper-converged
infrastructure market,” said Lee Caswell, vice president products,
Storage and Availability Business Unit, VMware. “Now that database
applications represent the top workload for VMware vSAN, flash
performance is critical. Customers looking for proven compatibility and
interoperability can turn to Toshiba Memory’s PM5 12Gb/s SAS SSDs.”
“Toshiba Memory enterprise SSDs are built to withstand the most
demanding performance and reliability needs of mission-critical
applications,” said Alvaro Toledo, vice president of SSD marketing and
product planning, Toshiba Memory America, Inc. “Working directly with
VMware to achieve certification for our PM5 SAS SSDs is key to providing
peace of mind to customers utilizing a vSAN solution.”
The PM5 Series of 12Gb/s SAS SSDs with VMware vSAN 6.7 and VMware ESXi™
6.7 certification is now shipping. Available options include customized
server OEM models also approved for vSAN all-flash capacity tier and
caching tier, as well as hybrid caching tier implementations.

1 Definition of capacity: Toshiba Memory Corporation defines
a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as
1,000,000,000,000 bytes. A computer operating system, however, reports
storage capacity using powers of 2 for the definition of 1GB = 230
bytes = 1,073,741,824 bytes, 1TB = 240 bytes =
1,099,511,627,776 bytes and therefore shows less storage capacity.
Available storage capacity (including examples of various media files)
will vary based on file size, formatting, settings, software and
operating system, such as Microsoft Operating System and/or
pre-installed software applications, or media content. Actual formatted
capacity may vary.
