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.
