Texas Memory Systems has acted to counter the courting of IBM's SAN Volume Controller (SVC) by Fusion-io's ioDrive flash memory by getting its RamSan-500 solid state drive certified interoperable with the SVC.
The SVC is a fabric-located controller that virtualises storage arrays in a storage area network (SAN). A demonstration, Project QuickSilver, was mounted by IBM and Fusion-io in which a lot of the latter's PCIe-connected ioDrive SSD products were hooked up to an SVC to achieve a million IOPS.
Now TMS has a ready-to-buy product that can be connected to the SVC and run at up to 100,000 IOPS. It says that its RamSan-500 is an enterprise-class, cached Flash storage system with a large RAM cache to buffer write performance, and 2TB of RAID-protected, hot-swappable single level cell (SLC) NAND flash that delivers better read performance than 300 hard drives while consuming 1/20th the power, 300 watts.
It offers 25,000 IOPS sustained random writes and 2GB/sec sustained random read or write bandwidth. The system can be SAN-attached with up to eight 4Gbit/s Fibre Channel ports. Multiple RamSan-500s can be scaled to deliver additional capacity.
The RamSan-500 can also be hooked up to NetApp's virtualising V-Series controller.
TMS introduced its own PCIe-connected SLC SSD, the RamSan-20, in March, offering 450GB of capacity and up to 120,000 random read IOPS.
Fusion-io's largest capacity ioDrive offers 320GB, uses multi-level cell (MLC) NAND technology, and provides up to 71,256 IOPS with a 4k read packet size. A 620GB ioDrive is expected later this year. ®
