PMC Maximizes Rack Storage Density for Open Compute Data Centers

  PMC Maximizes Rack Storage Density for Open Compute Data Centers   Adaptec by PMC’s 24-port RAID Adapter Enables New Levels of SAS/SATA Storage               Connectivity and Performance for OCP Architectures  Business Wire  SUNNYVALE, Calif. -- January 28, 2014  PMC® (Nasdaq:PMCS), the semiconductor and software solutions innovator transforming networks that connect, move and store big data, today announced high-density storage connectivity support for the Open Compute Project (OCP). With three times as many ports as other solutions, the Adaptec 78165 24-port RAID adapter enables the densest Open Rack storage capacity, connecting more Open Vault JBOD storage arrays per Winterfell server head node. A common scale-out configuration can now support connectivity for 360 drives per rack, a 33 percent increase in capacity, with fewer Winterfell servers (see infographic). This level of extreme capacity with leading performance per watt is critical for deploying storage at scale for workloads such as Hadoop Big Data Analytics or OpenStack Infrastructure as a Service (IaaS).  “By increasing the storage connectivity that an adapter can provide, PMC has redefined how a rack can be architected,” said Mike Yang, general manager of Quanta QCT. “With this level of connectivity density, we can increase storage density in the rack and deliver an efficient solution for today’s large-scale cloud data centers.”  “We have been working with PMC to benchmark the Adaptec 78165 RAID adapter in a Winterfell chassis,” said Steven Lu, senior director, Product Management, Wiwynn. “There is no better combination of performance and connectivity for high-density server environments.”  The reference architecture is based on the OCP’s Open Rack form factor that re-engineers the conventional data center rack for maximum power efficiency, serviceability and investment protection. The Adaptec 78165’s low-profile/MD2 form factor was designed for the high-density server environments that OCP Winterfell servers and Open Vault JBODs enable. It gives space-limited data centers the ability to deploy internal and external SAS and SATA connectivity and the latest PCI Express® 3.0 specification. The adapter can be used in RAID, Simple Volume or Physical Drive applications and performs at up to 6.6GB/s on sequential reads and up to 5.2GB/s on sequential writes (with RAID 0), more than doubling the performance of competing solutions.  “PMC’s high-density storage technology provides the connectivity to enable the Open Compute ecosystem, and it fits perfectly with the OCP’s mission for scalable, efficient and cost-effective storage,” said Jared Peters, vice president of Server Storage Solutions at PMC. “We’re committed to contributing to OCP work group specifications and other projects across the industry to enhance current and future data center solutions.”  Like other products in the Adaptec by PMC Series 7 family, the 78165 utilizes PMC’s 24-port RAID on Chip, mini SAS HD connectors and Zero-Maintenance Cache Protection (ZMCP), which uses flash memory to protect cached data and eliminates battery backup units. The Adaptec 78165 is available in volume production.  About Adaptec by PMC®  Adaptec by PMC storage solutions protect, accelerate, and condition data as it moves through the I/O path.
