ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
2.0 Diamond-VT Technical Overview
The Diamond-VT 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
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.
Using this technology, we are able to provide a
storage array that delivers faster sustained data
transfer rates as well as impressive I/Os per
second at a new price point in the storage market.
The Diamond 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.
