The Dual Mammoth Tape Subsystem is part of GST’s SafeDR™ family. All GST tape subsystems in this family are housed in upgradeable modular enclosures. Dual Mammoth Tape Subsystems generate identical sets of backup cartridges so that one set can be safeguarded remotely for disaster recovery while the other set is retained onsite for faster restores; other tape functions add off-line copy and cascading capabilities. An LCD panel provides an advanced operator interface for visibility over the backup operation.

Model Overview

GST’s Dual Mammoth Tape Subsystem is available in a variety models; Mammoth and Mammoth2. Each Mammoth technology is available in two server-to-SCSI Adapter interfaces:

Low Voltage Differential (LVD). Maximum SCSI negotiation of 160MB/s; the total server-to-storage peripheral connectivity is 12 meters.

High Voltage Differential (HVD). Maximum SCSI negotiation of 40MB/s; the total server-to-storage peripheral connectivity is 25 meters.

Mammoth Technology

Mammoth tape technology has evolved through two generations and provides read compatibility to existing Mammoth backups. The technology was originally created by Sony Corporation and later expanded by Exabyte Corporation.

Native cartridge capacities for Mammoth2 are 60GB (120GB compressed) with speeds of 43GB/hr (86GB/hr compressed). A 2-to-1 compression ratio is achieved with IDRC technology.

Key Benefits

Improved DR – Mirrored backup capability produces simultaneous sets of identical backup cartridges with no performance penalty; one set is stored off-site for better disaster recovery and the other set is stored on-site for rapid restore.

Fault-tolerant Backup and Restore – Dual-drive configurations ensure against drive failure since the second drive continues to operate.

Added Tape Functions – For dual-drive subsystems, key added tape functions include: dual-drive mirroring for mirrored backups, off-line copying/verifying with no processor penalty, and cascading to extend unattended backup capacity by switching from one drive to the other (doubles capacity).

Space Saver – The small dimensions and light weight of the modular configurations facilitate the optimum use of datacenter space.

Serviceability – Modularity of design permits individual drives and GST’s Dual Drive Controller to be easily replaced in building-block fashion by the user.

Key features

Stackable Enclosures – Individual modular enclosures enable each drive and controller to be handled as separate building blocks; field upgrades from single to dual drives are simple.

Dual Drive Controller – Manages mirroring, off-line copying, cascading, and the LCD Display Panel.

LCD Display Panel – Multi-function LCD Display Panel continuously displays key drive and backup job conditions.

Convenient Drive Interface – RS232 interface for updating firmware and optimizing drive performance.

Service and Support – A variety of support programs provide installation and onsite service; includes GST’s Accelerated Ship Program (GASP) to get replacement units on the scene rapidly.

Warranty – Purchase price includes built-in 3 year warranty
