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 Series uses lower cost ATA disk drives
combined with an intelligent midplane to create a
storage array with price and performance
characteristics.
The intelligent midplane contains hardware and
software which provide the proprietary ADXT, a
switched data management and data movement
technology. The storage array delivers faster sustained

ATA disk drives were known originally as Integrated
Drive Electronics (IDE), a low end disk interface. The
original IDE interface was low performance, single
threaded (no simultaneous I/O requesting), contained
minimal error detection and was unsuitable for

high reliability.
As IDE was refined and acquired important
capabilities, its name was changed to ATA, Advanced
Technology Attachment.
