PM5 series earns VMware vSAN 6.7 certification

Toshiba Memory Europe has announced that the newly released PM5 Series of 12Gb/s enterprise SAS SSDs has earned VMware vSAN 6.7 certification.

This certification enables these flash-based storage devices to be shared across connected hosts in a VMware vSphere cluster.

With vSAN 6.7 certification, users can pool PM5 Series SSDs together in a single, distributed, shared data store, enabling 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-converge 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 centre customers.

Built with Toshiba Memory’s 64-layer BiCS FLASH TLC (3-bit-per-cell) 3D flash memory, the PM5 Series offers up to 15.36TB capacities in a 2.5-inch form factor, and supports a full range of endurance and capacity ranges. It also utilises the industry’s first MultiLink SAS architecture delivering the fastest SAS SSD sequential performance to date.

In addition, the PM5 Series SSDs support multi-stream write technology – a feature that intelligently manages and groups data types together to minimise write amplification and garbage collection, which in turn, translates into reduced latency, improved endurance, increased performance and better Quality of Service (QoS).

The PM5 Series of 12Gb/s SAS SSDs with VMware vSAN 6.7 and VMware ESXi 6.7 certification is shipping now and includes customised server OEM models also approved for vSAN all-flash capacity tier, all-flash caching tier and hybrid caching tier implementations.
