3PAR Adds 500 Gigabyte Nearline Disk Drives
3PAR, a provider of utility storage, has announced that 500 gigabyte Nearline drives are now available, extending 3PAR Utility Storage across both Fibre Channel and Nearline storage tiers. These high-capacity drives target a variety of applications, including archiving, backup caching, and data replication.
Unlike traditional ATA-class drives, which would require distinct drive enclosures, 3PAR Nearline drives embed a Fibre Channel interface and are supported within the same enclosure as the 3PAR InServ Storage Server's Fibre Channel disk drives. 3PAR Nearline disk drives offer an alternative to Fibre Channel drives for select applications and address some of the drawbacks associated with similarly inexpensive ATA drives. Some benefits of Nearline drives over ATA include the following:
Higher reliability: Nearline drives are rated for higher mean time between failure and for more rigorous duty cycles with near-continuous 24x7 workloads.
Higher availability: Nearline drives include dual-ported Fibre Channel paths and control logic for monitoring, analyzing, and reporting on disk drive health.
Higher performance: Nearline drives include several performance enhancing features, including optimized command queuing and full duplex access.
When combined with 3PAR Utility Storage -- a scalable fully-tiered storage array -- the advantages of Nearline drives are leveraged. The 3PAR InServ Storage Server can provide a variety of data service levels (performance, availability, cost) by application volume and, with 3PAR Dynamic Optimization, can dynamically move these volumes across tiers.
"The addition of Nearline drives to 3PAR's InServ Storage Server is the latest in an impressive build-out of 3PAR's utility computing vision," said Anne MacFarland, Director of Infrastructure Architectures and Solutions at The Clipper Group. "Now, 3PAR InServ users can consolidate the stored data of more applications in a single environment-and, for some enterprises, in a single enclosure."
"Customers quickly realize that they can enjoy tremendous cost benefits by consolidating storage tiers with 3PAR Utility Storage," said David Scott. "With Dynamic Optimization, Thin Provisioning, fast RAID 5, and now Nearline drives, 3PAR lets enterprise customers stretch their capacity budgets farther than anyone."
