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.
