Marvell to release DRAM, SSD-based accelerator card

Lucas Mearian, Computerworld | April 4, 2011
SANTA CLARA, Calif. -- Solid-state drive chip maker Marvell Technology today announced that later this year it will release an accelerator card designed to deliver a tenfold increase in storage network throughput by caching and sorting data at the server before sending it to back-end arrays.

"That's a key difference in the way the DragonFly operates. It has L1 DRAM cache that buffers the SSD so you don't hit that random-write cliff," Gole said. "You can still have SSDs in your SAN or NAS array, but you're not going to get as high I/OPS as you will with a host cache."

The DragonFly VSA is undergoing initial tests with select Marvell customers. It's expected to go into beta testing this summer and will be available about three months after that, Kung said. Pricing has yet to be set, he said, but added that the cards will sell for under $2,000.
