IBM said it’s testing a 4-terabyte, high-speed solid-state drive array targeted at the enterprise, as the technology giant gives its imprimatur to flash-memory-based storage.
Under the rubric Project Quicksilver, IBM coupled solid-state drives with its storage virtualization technology to achieve a sustained data transfer rate of more than 1 million input/output per second (IOPS), with a response time of less than one millisecond in a 4.1-terabyte rack of SSD storage. SSDs are being supplied by Fusion-io.
By comparison, Intel is commercially shipping SSDs (X25-E Extreme) that individually achieve random data reads of 35,000 IOPS and random writes of 3,300 IOPS. In a 3.8-terabyte storage array using 120 SSDs, Intel claims 4.2 million IOPS.
IOPS is a crucial benchmark for large customers that process credit card information or run reservation systems, for example.
