1.0 Diamond Storage Array-VT Product Overview

The Diamond Storage Array-VT Class offers up to 30 Virtual Tape drives and up to 60 virtual tapes in a rack mount or floor model configuration.

The Diamond-VT appears and functions to ISV (Independent Software Vender) applications as if it were a traditional tape device although it is actually an array of ATA disk drives. Virtual tape provides increased performance for restore and backup operations, RAID protection of data, and compatibility with existing software and backup procedures. Virtual Tape can be used anywhere traditional tape is used to augment and enhance existing tape drive/library investments.

With the cost effective approach of using ATA disk drives, you can add more storage capacity as your needs grow without the costs of other disk storage technologies. You can also improve the performance and capacity of the Diamond-VT cabinet as technology progresses by simply replacing disk drive sleds and host interface cards.

The Diamond-VT is operating system independent and supports all popular computer hardware platforms and network environments.

Two interface options are available: a 2-gigabit Fibre Channel interface and an Ultra160 SCSI interface.

The Diamond-VT is a fully populated, turnkey solution with drives pre-installed. It is fully supported by a highly trained customer service and engineering staff.

The Diamond-VT uses Aggregated Data Transfer Technology (ADXTJ) to merge the performance of multiple ATA drives to achieve sustained, full bandwidth data transfer rates. ADXT provides end users with the power and sophisticated data control needed to take moderately priced ATA disk drives, combine them in a disk storage array, and power them to the performance levels of SCSI or Fibre Channel disk arrays.

Diamond-VT features

•Up to 7.2 Terabytes initial configuration (expandable with future drive technology)

•Supports most major operating systems and ISV software applications

•Configurable up to 30 Virtual Tape Drives
