PMC-Sierra has unveiled the SRCv family of 6Gb/s SAS RAID-on-Chip (RoC) Controllers, including the 24-port RoC, which enables the highest levels of server performance and connectivity, along with an eight-port RoC targeted at the volume x86 server market.
The company claims that SRCv family of 6Gb/s SAS RAID-on-Chip (RoC) Controllers has more than double the IOPS and throughput performance of existing offerings, and fully leverage PCI Express(R) 3.0. The devices are SAS 2.1 compliant and consume 30% less power than comparable offerings.
According to PMC-Sierra, the SRCv family integrates the latest in host, drive and memory interface standards with RAID hardware acceleration and an advanced multi-core processor subsystem. RoCstar technology improves system performance by increasing I/O throughput and lowering latency.
In addition, it also includes DDR3-1600 Memory Controller; RoCstar contention-free architecture; single-root IO virtualisation (SR-IOV) support; high performance MIPS-based(TM) multi-processor subsystem; block DMA engine; and hardware XOR and Reed-Solomon Engines for RAID 5 and 6 acceleration.
Derek Dicker, vice president of marketing, enterprise storage Division at PMC-Sierra, said: "PMC-Sierra’s SRCv family represents a major advancement in RAID-on-Chip technology that will help our customers deliver storage solutions to address the increasing system performance demands driven by virtualisation and enabled by SSDs.
"Compared to our first-generation SRC device, the SRCv delivers a stunning doubling in performance in a similar power envelope, and simultaneously shrinks the package size of the device by roughly 20%. These advancements support PMC-Sierra’s continued pursuit of technology and product leadership in the enterprise storage semiconductor market."
