RamSan-620

The RamSan-620 offers scalable performance and affordable high capacity that is space and power efficient as well. A single unit provides from 2 to 5TB of reliable Single Level Cell (SLC) Flash, making the RamSan-620 the highest capacity SLC Flash SSD on the market. It also leads the industry in performance with 250,000 sustained I/Os per second (IOPS) for random reads and random writes. Throughput is 3GB per second and latency ranges from 80 to 200 microseconds, 25 times less than high performance hard disk drives. The RamSan-620 is a green IT choice, occupying only 2U of rack space and requiring only 325 Watts of power. In order to achieve similar performance, hard disk solutions would require as many as 500 drives, occupy 36 disk enclosures requiring nearly three full racks, consume over 7,000 Watts, and cost upwards of half a million dollars by the time the enclosures and controllers were included.

Each RamSan-620 unit can support 2 to 8 Fibre Channel (FC-140) or up to 4 InfiniBand (IB-140) links. Installation and management are simple, with embedded management capabilities and clear displays. One or more RamSan-620s can easily be integrated into a mixed storage infrastructure and monitored and managed through a common management framework.

Automatic Error Checking

Storage data integrity is provided by the use of SLC Flash chips with two independent methods of ECC. Each Flash chip incorporates an ECC data field within the chip for initial checking.  Additionally, each set of Flash chips is organized as a board-level RAID; thereby eliminating any single chip failure from corrupting data.
