Texas Memory Systems launches the RamSan-6200 SSD System that offers up to 100 terabytes of Flash-based storage in a 40U rack configuration that can sustain a record 5 million input/outputs per second (IOPS) with 60 gigabytes per second throughput while using a little over 6 kilowatts of power.

To achieve the equivalent level of performance with hard disk-based storage arrays would require several thousand of the 15,000 RPM hard disk drives.

The RamSan-6200 is a scaled up system that combines twenty RamSan-620 solid state disks in a single datacenter rack and uses Texas Memory Systems’ TeraWatch software to provide unified management and monitoring from a single GUI console. The system utilizes enterprise grade Single Level Cell (SLC) Flash as well as multiple levels of RAID and advanced Flash management algorithms.

A single RamSan-620 unit provides 5TB of Single Level Cell (SLC) Flash with 250,000 sustained IOPS for random reads and random writes. Each RamSan-620 unit can support 2 to 8 Fibre Channel or up to 4 InfiniBand links.

At the chip level, TMS uses only SLC Flash memory. Each Flash chip incorporates an Error Checking and Correction (ECC) data field within the chip to check and correct single-bit errors.

At the board level, each set of Flash chips is organized as a board-level RAID, thereby eliminating any single chip failure from corrupting data.

At the system level, the RamSan-620 allows to designate one of the cards inside the system as an active-spare that works hand-in-hand with the chip level RAID on each of our boards. If one of the cards experiences a failure that degrades its RAID protection, the system will immediately migrate the data on that card to the hot-spare to return to a fully redundant state.
