Purpose-built for high volume,
fail safe data storage applications, the Granite Rack Series sets
new standards in its class.
Adding external storage to your server is no longer the complicated
and daunting task is was years ago. The Granite Rack line of external
options makes increasing your overall storage requirements a simple,
time saving procedure.
The Granite Rack Series utilizes the latest technology to reduce the overall cost to you.
Until just recently SCSI Hard Drives were the only solution for external options, but now with
the emergence SCSI to SATA technology, SATA drives can also be
implemented.

Supports most operating systems,
platforms and network environments due to the unit working independently
from the OS.
|
| |
Ultra160 SCSI channel interface
to your Host computer.
|
| |
Up to 160 MBps transfer rate.
Large and complex files are handled easily.
|
| |
Selective SCSI ID 0 to 15. Each
Granite-Rack storage unit uses only one ID.
|
| |
Selective RAID levels 0, 1, 3,
5, 6 or 0+1. |

Concept of RAID |
| |
RAID (Redundant Array of Independent Disks) is an acronym first used in
a 1988 paper by Berkeley researchers Patterson, Gibson and Katz. The paper described array configuration
and applications for multiple inexpensive hard disks which in turn provided redundancy and better access rates.
When a RAID is created, accessing multiple individual disks now act as if the array were one large disk. It spreads
data access out over these multiple disks, thereby reducing the risk of losing all data if one disk fails, and improving
access time.

Why RAID? |
| |
Typically RAID is used in large file servers, transaction of application
servers, where data accessibility is critical and fault tolerance is required. Recently desktop users
started to use RAID for almost any application where massive storage or high data transfers are required.
RAID offers data production by utilizing striping, mirroring or
both.
