2.0 Diamond Storage Array Technical Overview
The Diamond Storage Array uses Aggregated Data Transfer Technology (ADXT) to achieve the high
data transfer performance you need. ADXT
merges the performance of multiple ATA drives together to
achieve sustained, full bandwidth Fibre Channel data transfer rates.
Unlike other storage arrays which use expensive
SCSI or Fibre Channel disk drives to achieve
performance, the Diamond Storage Array uses
lower cost ATA disk drives combined with an
intelligent midplane to create a storage array with
exceptional price and performance
characteristics.
The intelligent midplane contains hardware and
software which provide the proprietary ADXT
, a
switched data management and data movement
technology, to create a higher performance
storage solution.
The Diamond Storage Array is made up of dual
SCSI or Fibre Channel Host Interface Cards, the
intelligent midplane, a system management card,
and 12 independent disk drive sleds containing up
to 24 ATA disk drives.

The original notion of RAID was to build high
capacity, reliable storage subsystems using large
numbers of inexpensive disk drives. Thus its
original definition:
Redundant Array of
Inexpensive Drives
. Over time that definition
became
Redundant Array of Independent Drives
and the inherent cost advantage in a RAID system
was lost. The Diamond Series provides a high
capacity, high performance and highly reliable
