EMC under the name of VFCache is a pci-e card announced that 300GB of nand memory is available. The flash memory is meant to be in a server to be placed and is used for caching of frequently used data.
The half-length x8 pci-e cards in the VFCache series feature 34nm slc flash memory chips from Micron. The cards will have a total of 300GB of nand flash are placed. EMC states that a VFCache card is 750,000 iops random 4K-leesacties and 91.000 iops at random 4K writes. The sequential read and write speeds would be 3 and 0.8 GBps amounts to 128K-blocks, while the latency would be lower than 50µs. A VFCache card verstookt 25W.
According to EMC the VFCache hardware by direct access via the pci-express bus to the cpu for a considerable speedups compared to ssds and hard drives. The cards serve as cachinglaag in servers with EMC a driver represents to determine which data is suitable for the ‘flash cache’. Also, is a link possible with the Fully Automated Storage Tiering platform from EMC. How much the VFCache card is going to cost, is not yet known.
