The Promise 450GB SAS Drive Module with first-generation design is a hot-pluggable upgrade or replacement hard drive for VTrak subsystems.
SAS (Serial Attach SCSI) hard drives
SAS drives deliver higher sequential performance and outstanding random access performance for the most demanding applications. They also provide best-in-class mean time between failure (MTBF: 1,400,000 hours). SAS drives are ideal for applications requiring the highest performance, fastest random access times, and highest reliability available.
Tiered storage in a single RAID box
The Promise VTrak E-Class drive modules can be mixed inside a single RAID subsystem or in the expansion chassis allowing for flexible tiered storage configurations. 15,000-rpm SAS drives are best utilized for mission-critical applications requiring maximum random read/write performance.
Promise SAS drive module compatibility
These SAS drive modules are qualified for use with Promise VTrak E-Class RAID subsystems and VTrak expansion chassis only. The 450GB drive can substitute for a 300GB drive as a replacement or spare in an existing RAID set although the extra capacity will not be utilized.
