PrimeStor - Ultra3 LVD RAID Array



Key Benefits
PrimeStor RAID array is offered in single and dual SCSI RAID controller configurations. Fiber Channel RAID controller is also available as an option. PrimeStor RAID delivers improved performance through the use of an Ultra3 SCSI host interface or a Fiber Channel interface, and is operating system and platform independent. Ultra3 SCSI delivers burst transfer rate of up to 160MB/sec for Ultra3/Wide (LVD) interface. Data transfer rates of up to 200 MB/sec are possible with the Fiber Channel option.

Each PrimeStor RAID supports up to thirty-two half-height 3.5" disk drives in hot-swappable canisters.

Low service and integration costs are guaranteed by the PrimeStor's cableless design and redundant, hot-swappable power supplies, cooling fans, and embedded RAID controller.

Data integrity is assured by an internal battery that provides protection against data loss due to extended AC power failure (embedded RAID controller version only)




Drive Capacity
Drive capacities of 9.1GB (7,200 / 10,000 rpm), 18GB (7,200 / 10,000 / 15,000 rpm), 36GB (7,200 /10,000 rpm), 73GB (10,000 rpm), 146GB (10,000rpm), and 180GB (7,200 rpm)

Maximum capacity 5760GB when using 180GB drives.

Scaleable to multiple terabytes.




Graphical User Interface
PrimeStor RAID ships with GUI software. This software enables system administrators to monitor and control their RAID systems by displaying the status of many RAID components, including RAID set status. It also allows the administrator to perform such actions as creating a RAID set, creating hot and/or warm spares, and rebuilding RAID sets. Some versions of the software also support remote notification using a variety of user configurable mechanisms, such as e-mail, fax, or pager.
