Marvell has launched the DragonFly Virtual Storage Accelerator (VSA) powered by the company's HyperScale embedded processor technology.

In what is a first for Marvell, the DragonFly VSA, which plugs directly into all commercially available servers with a PCIe slot, combines Marvell's chip technology with its newly designed circuit boards.

The DragonFly VSA represents a new architecture in the industry, achieving the benefits of virtualization scaling and enterprise NAS/SAN/DAS storage cost reduction via turn-key hardware.

"The Marvell DragonFly VSA is a revolutionary product for enterprise-class cloud computing, offering powerful host server I/O cache acceleration to solve worsening storage I/O bottlenecks," said Pantas Sutardja, chief technology officer at Marvell.

The DragonFly VSA is a purpose-built, turn-key solution designed to provide benefits to enterprise data centers (private clouds) and hosted service providers (public clouds). Powered by HyperScale embedded technology, the DragonFly VSA enables cloud computing deployments to break through the storage I/O barrier by enabling 10x virtual server IOPS while lowering NAS/SAN/DAS storage costs by 50 percent or more. The DragonFly VSA enables the creation of a next-generation cloud-optimized data center architecture where data is automatically cached in a low-latency, high-bandwidth "host I/O cache" in application servers on its way to/from higher-latency, higher-capacity storage. The DragonFly VSA is designed to create a host I/O write and read cache that is agnostic to storage protocols and can be configured as a data cache for NAS, SAN or DAS storage arrays.

The DragonFly VSA's distributed host I/O cache employs a two-level cache for very low-latency and high burst throughput. The two levels are composed of a level-1 non-volatile random access memory (NVRAM) cache and a level-2 cache created from off-the-shelf commodity SSD drives. The two-level cache enables consistent, high-level performance to applications running on the host server.

As an industry standard PCIe adapter, the DragonFly VSA offers a turn-key "appliance-on-a-card" that fits seamlessly into all commercially available rack-mount servers and is operating system independent. By offering an add-on card to commodity servers, the DragonFly VSA enables a cost-effective distributed host cache that incrementally scales IOPS and NVRAM/SSD capacity as your application servers grow over time.

Powered by embedded HyperScale technology, Marvell DragonFly VSA is designed to offer the following high-value features for cloud computing storage deployments:

???10x write performance via flash-aware write buffering & re-ordered coalescing;
???10x read performance via intelligent block/file read caching algorithms;
???HA synchronous mirroring for SPOF protection;
???Zero-warm up cache upon power loss; and
???Multi-protocol storage caching (NFS, iSCSI, FCP, FCoE, SCSI DAS)

Beta trial sampling for the DragonFly VSA is expected in CQ3 2011.
