"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.
