T-Platforms ReadyStorage DAS 1331/1333

 

1333ReadyStorage systems with external SAS interface are ideal for direct attachment to servers (up to six servers) and clustered (up to three servers) infrastructures.

Concurrent usage of SAS and SATA drives (3 Gb/s) in one storage enables both data processing and their backup, thus enhancing functionality and reducing total cost of ownership.

Usage of two active RAID controllers with mirrored cache, power supply and cooling redundancy, hard drive and I/O path backup capabilities make these systems a great solution for clustered infrastructures, where performance and continuous data and application availability are critical requirements.
