EqualLogic, a provider of enterprise-class iSCSI storage area network (San) solutions, has announced a range of storage arrays featuring high-performance Serial Attached SCSI (SAS) disk drives.
Combined with PS Series Version 3.0 firmware, the PS3000 Series allows the company’s Sans to be configured with multiple performance tiers under a single management interface. With the new solution, EqualLogic believes that IT managers will be able to match the specific performance, capacity and cost characteristics of each tier of storage to applications that serve the needs of different business objectives.
Extending the PS Series family beyond EqualLogic’s core SATA-based product line, the series is claimed to provide high-performance storage that can cope with demanding database and online transaction processing applications. The PS3000 Series includes two SAS-based storage arrays: the PS3800XV with 15,000 rpm 146 gigabyte drives offering 2.4 terabytes of storage and the PS3600X with 10,000 rpm 300 gigabyte drives and 4.8 terabytes of capacity. Both arrays are fully compatible with all installed EqualLogic SANs.
Among the features of the PS Series family is the ability to have multiple tiers of storage in a single San, allowing IT managers to optimise the performance and capacity of each tier according to application demands.
Data placement can be continuously optimised according to application behaviour. This includes automatic load balancing data across disks, RAID levels and network connections that yield optimal application performance within each tier. Online data movement between tiers allows application data to move without any business disruption, as application behaviour and business priorities evolve.
