12Gb/s SAS Flash manager enables high-performance SSDs for cloud servers
June 11, 2012 // Julien Happich
PMC has announced a 12Gb/s SAS Flash manager (SFM-12G) for the next wave of enterprise solid state drives (SSDs), claimed to be the first end-to-end 12Gb/s SAS solution from the protocol controller to the SSD controller.
The PM8304 SFM-12G enables more than 300,000 I/Os per second (IOPS) in a 2.5” SAS SSD, more than double the performance of today's 6Gb/s SAS SSDs. When paired with the industry’s highest performing protocol controller, the SPCv 12G, cloud server and big data storage manufacturers can deliver a stunning 2.4 million IOPS in an eight-drive, enterprise-class flash subsystem.
The PM8304 SFM-12G combines the manufacturer's proven 12Gb/s SAS technology with the industry’s lowest latency and innovative maxLIFE adaptive error correction, enabling storage equipment and drive manufacturers to deliver true enterprise-class SSDs. Historically, SSD controllers had to trade off latency, a key benefit of NAND, against life expectancy, a key requirement for enterprise systems. PMC’s maxLIFE technology solves this dilemma by extending the usable life of SSDs and maintaining the lowest error-correction latency over the life of the drive. This new technology allows OEMs to take advantage of the substantial economic benefits of MLC flash without compromising enterprise-class durability.
