Features and Benefits

HGST incorporates specialized software and hardware that combine to implement Storage Class Memory (SCM) within the server. The HGST architecture has been designed to tightly integrate different kinds of flash media, hardware and software to deliver memory-class performance with storage-class capacity and persistence. HGST’s FlashMAX® II SCM devices and associated software deliver performance without compromise, along with HDD-like capacity in a very compact, universal form factor.

vFAS™

vFAS is an Adaptive Scheduling algorithm, which delivers the most efficient access to flash media for applications. In addition to providing optimized access for peak performance, vFAS also includes sophisticated techniques to ensure applications get steady sustained performance at all times. vFAS virtualizes the underlying flash media to present a standard block device interface to applications, without inefficient storage protocols or interconnects, resulting in significant gains in application performance.

FlashMAX II presents a traditional block storage volume to the host so that applications can easily access it without modification. vFAS has been designed to treat flash media more like an extension of memory, while maintaining a traditional block storage interface for applications. All of this is done without the use of storage protocols, storage controllers or storage interconnects. The result is latencies under 21 μs, which is closer to DRAM performance.

Unconditional Performance

FlashMAX II with vFAS delivers consistent performance across all application workloads, even when the device is fully utilized. FlashMAX II with vFAS delivers application performance whether it is peak small block read performance, where a single low profile card can deliver over 1.1 million IOPS, or sustained mixed read/write performance when the drive is full.

Simplified Management

Unlike many competing solutions, 100% of the capacity available on a FlashMAX II card is available as a single host volume on the server without having to leverage 3rd party software RAID products to stripe across multiple drives. With FlashMAX II you can have a single volume presented to the operating system up to the advertised formatted capacity, which can be as large as 4.8TB when using the FlashMAX II Capacity model.
