Product Overview

• High performance 2U expansion disk
• Provides Tandberg DPS1000 Series VTL with up to 9TB raw storage (up to 7.5TB useable, uncompressed)
• Scales up to 45TB raw storage (up to 37.5TB useable uncompressed)
• Supports RAID 5 configuration with hot sparing
• Allows hot swapping of any system components
• 3 years warranty, 1 year onsite service (5x8xNBD)

By using high-performance, cost-effective disk storage to emulate a traditional tape library, the DPS1000 Series VTL optimizes performance of data management operations, providing almost immediate access to data and dramatically reducing backup and recovery time. When businesses need more than 5TB storage, users can add the DPS Expansion Module. With its stand-alone storage capacity, users can easily grow the available storage space for virtual tapes created by the DPS1000 Series.

The DPS Expansion Module is a Serial Attached SCSI (SAS)-connected controller consisting of two arrays. Each each contains six (6) 750GB disks (4.5TB raw storage capacity) for a total system capacity of 9TB raw storage. The DPS Expansion Module supports RAID 5 configuration, so each array contains 3.75TB of useable, uncompressed storage capacity for a total of 7.5TB.

With built-in 2:1 data compression and accounting for file system overhead, each array has approximately 7.4TB or 14.8TB of total available storage capacity per controller.

High Performance
When rigorous data protection applications manage large volumes of data, high performance system throughput is critically important. The DPS Expansion Module combines SAS connectivity and reliable, high-capacity SATA-II disk storage devices to deliver high-speed data throughput.

Dynamic Load Balancing
To help keep systems running at peak efficiency, the DPS Expansion Module dynamically adjusts available storage capacity and provides automatic balancing across the arrays. Balancing takes place when disks are idle, so normal data protection operations are not impacted.

Scalable, Expandable Storage
Long-term data protection solutions must scale to meet growing business needs. The DPS Expansion Module offers an easy upgrade path through daisy-chaining up to four additional storage module enclosures. Potential maximum raw storage capacity is 45TB, and maximum usable, uncompressed storage capacity is 37TB. With 2:1 data compression, actual storage capacity grows to 74TB.

Reliable Data Protection
Data protection operations require reliable infrastructure for long-term viability. To achieve maximum reliability, the DPS Expansion Module uses two separate RAID 5 configurations on each of its disk arrays to provide fault tolerant, guaranteed data recovery from drive failures. In addition, the DPS Expansion Module supports the option for hot swapping of components in the system chassis.

Intuitive Web-Based Management
The DPS Expansion Module can be easily managed using an intuitive and fully-automated web-based graphical user interface (GUI). Critical system alerts, such as a disk failure, can be received via email or through the use of an SNMP server.

Service and Support
The DPS Expansion Module comes with 1 year Onsite Service (5x8xNBD) and 3 years warranty. Additional service options are available.
