GST Autoloaders provide an excellent upgrade path for sDLT tape technology users and are a convenient way to capture a full week’s daily backups unattended.

The Big Picture

• Eight sDLT600 or sDLT320 cartridges in an autoloader.
• Capacity: sDLT600 is 2.4TB native (4.8TB compressed).
• Speed: sDLT600 is 130GB/hour native (260GB compressed).
• Simplified unattended weekly backup.
• Logical extension of GST’s single and dual sDLT drives.
• Supports sDLT320 and sDLT600.
• Roadmap to sDLT1200 and sDLT2400.
• LCD operator panel improves backup efficiency.
• sDLT range: single drive to enterprise-wide libraries.

GST’s Workgroup sDLT Autoloader is part of our AutoDR™ family. This Autoloader uses sDLT320 and sDLT600 tape technology and provides unattended backup capacity ranging up to 2.4TB native (4.8TB compressed). This compact autoloader spans the gap between GST’s Single and Dual Tape Subsystems on one end and GST’s tape libraries on the other end, adding considerable granularity to the GST tape product line. With the 8-cartridge configuration, total unattended backup capacity exceeds that of a single tape drive by 7 to 10 times. An LCD panel provides an advanced operator interface for visibility over backup operations.

The autoloader holds eight data cartridges, or seven data cartridges and a cleaning cartridge. The Workgroup sDLT Autoloader can be used in a 7-day tape rotation procedure, allowing a full week, or even months, of unattended and automated data protection. An integrated mailslot (IO slot) allows for importing and exporting data cartridges without the need for a cartridge re-inventory.

The Workgroup sDLT Autoloader can backup a wide variety of servers. They connect natively with LVD (low voltage differential), HVD (high voltage differential), and FC (Fibre Channel) interfaces.

Model Overview

GST’s Workgroup sDLT Autoloader is configured in two server-to-SCSI Adapter interfaces and one fibre interface:

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.

Fibre Channel (FC). 2Gbit fibre interface.

sDLT Technology

sDLT tape technologies supported are sDLT320 and the newer sDLT600. Native capacities for sDLT320 and sDLT600 are 160GB and 300GB (320GB, 600GB compressed) with speeds of 58GB/hour and 130GB/hour (115GB/hour, 260GB/hour compressed). A 4-generation roadmap provides for a native capacity of 1.2TB per cartridge (2.4TB compressed) and a transfer rate of up to 360GB/hour (720GB/hour compressed).

The sDLT is based on the technology platform that more companies trust to protect their business critical information asset than any other: DLTtape. Specifically designed for the high duty-cycle requirements of the high-end and automated environments, sDLT drives are rated at 250,000 hour Mean Time Between Failures (MTBF) at a 100% tape motion. A low-tension tape design, simple tape path and the proven reliability of linear serpentine tape recording combine to provide users with rock solid reliability and data integrity.
