GST’s tape controllers provide hardware-level functions that set GST tape solutions apart.

The Big Picture

• Virtual Library Partitioning: enables backup consolidation.
• Mirrored Backup: for improved disaster recovery.
• Off-line copying with no server resources.
• Attaches to OS/400, Unix, Linux, Windows.
• Utilizes PCI-X (Ultra 160) Technology.
• Fault-tolerant capability with dual drives.
• Supports LVD and HVD SCSI connections directly.
• Supports Fibre Channel via our bridges and routers.

GST Library Controller is part of the Commander™ family and provides a variety of unique capabilities that are not commonly found in tape backup systems: Virtual Library Partitioning, Mirrored Backup, off-line copy and an LCD Display Panel for operators.

The Library Controller facilitates onsite servicing to upgrade any one-drive library to a two-drive library or to add functionality.

The Library Controller attaches to a wide variety of servers. They connect natively with LVD (low voltage differential) and HVD (high voltage differential) SCSI connections, and with Fibre Channel (FC) through our BridgeLink™ family of bridges and SanMatrix™ family of routers.

Model overview

GST’s Library Controller is available in two models. Each model corresponds to a server-to-SCSI Adapter configuration shown below:

Low Voltage Differential (LVD). Maximum SCSI negotiation of 320MB/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.

Benefits

Field Upgrade to Two Drives – The Library Controller supports easy field upgrades from a one-drive library to a two-drive library and to add key functions: Virtual Library Partitions, Mirrored Backups for greater disaster preparedness, and off-line copying/verifying without using system resources.

Utilize PCI-X (Ultra 320) Technology – Take advantage of newer, faster SCSI technologies as they become available. The Ultra 160 standard delivers a transfer rate of 160 MB/second and replaces earlier SCSI versions: Fast Wide SCSI (20 MB/sec.) and Wide Ultra SCSI (40 MB/sec.).

Hardware Investment Protection – The Library Controller permits the investment in GST’s one-drive library to be retained when it is field-upgraded to a two-drive library.

Fault-tolerant Backup and Restore – In the event of a drive failure within a two-drive library or library module, the Library Controller continues to operate the second drive, ensuring the backup is completed successfully.

Features

IBM 3580 Emulation – This provides newer Low Voltage Differential (LVD) connectivity that is needed to support the PCI-X (Ultra 160) SCSI standard; also supports High Voltage Differential (HVD) SCSI connection.

Added Tape Functions – For two-drive libraries, key tape functions are supported: Virtual Library Partitioning, dual-drive mirroring for Mirrored Backups, and off-line copying/verifying without using system resources.

LCD Display Panel – Real-time operator information is provided by the multi-function LCD Display Panel that continuously displays status of drives, robotics and state of the backup operation.

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 a built-in manufacturer’s warranty of three years.
