Businesswire reports that Texas Memory Systems, Inc. (TMS) has introduced its patented Variable Stripe RAID (VSR) error mitigation technology on the RamSan-70 PCIe Flash card. This offering sets a new standard for Flash reliability through the addressing of plane and chip failures by dynamically bypassing failed Flash, reducing maintenance requirements and extending operating lifecycles. The VSR forms a core portion of the TMS enterprise SSD reliability technology suite.
“According to Dan Scheel, President of Texas Memory Systems, Variable Stripe RAID technology is another TMS innovation that maximizes return on SSD investments and minimizes maintenance downtime.’ To further understand the benefits of VSR, consider a hypothetical SSD made up of 25 individual Flash chips. If a plane failure occurs that disables an eighth of one chip, a traditional RAID system would remove a full 4% of the raw Flash capacity. TMS VSR technology bypasses the failure and only reduces the raw Flash capacity by 0.5%, an 8x improvement. TMS tests show that plane failures are the second most common kind of Flash device failures, so it is very important to be able to handle them without wasting working Flash.’”
