PMC-Sierra Inc. unveils the SRCv family of Raid-on-Chip (RoC) controllers, which includes the 24-port PM8015 SRCv 24x6G and the eight-port PM8020 SRCv 8x6G, that are SAS 2.1 compliant and are targeted at the volume x86 server market.

Both SRCv devices are based on PMC-Sierra's proven RoCstar architecture and multi-core processor sub-system, more than double the IOPS and throughput performance of existing solutions, and fully leverage PCIe 3.0. The devices consume 30 per cent less power than comparable solutions.

"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," said Derek Dicker, VP of marketing, enterprise storage division, PMC-Sierra. "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 per cent. These advancements support PMC-Sierra's continued pursuit of technology and product leadership in the enterprise storage semiconductor market."

PMC-Sierra's SRCv devices are based on the same multi-core processor sub-system and RoCstar architecture as the SRC 8x6G RoC controller. The architecture interconnects all device sub-systems, eliminating internal bottlenecks and resource contentions that limit competing shared-bus solutions. By enabling simultaneous access to all chip resources, RoCstar technology increases I/O throughput and lowers latency, delivering a performance increase in time-critical functions such as RAID rebuilds and data backup.

"Clients require next-generation server and storage technology leveraging high speed SAS connectivity to maximise performance of their business applications," said McLeod Glass, director of marketing, industry standard servers at HP. "By integrating HP's 6Gbit/s SAS SmartArray products with PMC-Sierra's RAID-on-Chip controller, HP delivers impressive levels of performance, reliability and power efficiency for next-generation scale-out storage platforms."

The SRCv family integrates the latest in host, drive and memory interface standards with RAID hardware acceleration and an advanced multi-core processor sub-system.

The PM8020 SRCv 8x6G and the PM8015 SRCv 24x6G are sampling now to select OEM customers.
