GST’s Midrange SAIT Library is part of our GrowthDR™ family. This mid-sized library uses sAIT-1 tape technology to provide 22TB native (57TB compressed) of automated unattended backup. It spans the gap from GST’s Single and Dual Tape Subsystems on one end to our larger enterprise-wide libraries on the other end. A variety of unique capabilities not found in other tape backup systems include: Virtual Library Partitioning, Mirrored Backup and Off-line Copy.

The Midrange sAIT Library holds up to eleven 4-cartridge magazines for a total capacity of 44 cartridges. Magazines facilitate organizing tapes for off-site storage. Magazines can be used in a 7- or 10-day tape rotation procedure, allowing a full week or more of unattended backup. Each Single-drive model of the Midrange sAIT Library is field-upgradeable to two drives and can be configured with Mirrored Backup capability for improved disaster recovery or with Virtual Library Partitioning for backup consolidation.

This library can backup a wide variety of servers. They connect natively with LVD (low voltage differential), HVD (high voltage differential), and FC (fibre channel).

Model Overview

GST’s Midrange sAIT Library is available in a wide variety of desktop and rackmount models. Library configurations for four different functions are available in three types of interfaces.

Listed below are the four different functional configurations:

Single-Drive Library. Automated unattended backup for one server. One drive; 44 cartridges.

Two-Drive Library. Designed for one server; permits separate backup jobs to run simultaneously on each drive. Two drives; 44 cartridges allocated as needed.

Mirrored Library. Designed for one server; produces identical backup sets simultaneously; supports Disaster Recovery. Two drives; 44 cartridges (22 per drive).

Virtual Library. Designed for backing up two servers. Two drives; 44 cartridges allocated as needed.

Listed below are the three types of 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.

Fibre Channel (FC). 2Gbit fibre interface.

sAIT Technology

Native cartridge capacities are 500GB (1.3TB compressed) with speeds of 108GB/hour (281GB/hour compressed). A 4-generation roadmap provides for a native capacity of 4TB per cartridge (10.4TB compressed) and a transfer rate of up to 864GB/hour (2.25TB/hour compressed).

This new sAIT tape technology platform delivers high capacity and high performance using a half-inch, single-reel tape and a 5.25-inch full-height mechanism design, dramatically improving the value proposition between conventional tape roadmaps and future hard disk drive capacity trends. As a new class of tape solution, sAIT technology leapfrogs conventional linear solutions, offering significant advantages in capacity, performance, reliability, and scalability.

Key Benefits

Improved DR – GST’s Mirrored Backup function produces simultaneous sets of identical backup cartridges with no performance degradation and no software overhead; this provides off-site storage of one set to facilitate disaster recovery and a second set kept on-site for rapid restore.

Backup Consolidation – Backups can be consolidated with GST’s Virtual Library Partitioning that partitions a multiple-drive library to back up two different hosts or LPARs within a single tape library.

WORM Enabled – sAIT-1 drives are available with Write Once Read Many (WORM) technology. WORM provides tamper-proof data protection with non-rewriteable and non-erasable data storage.

Simplified Weekly Backups – A rotating carousel holds eleven magazines with up to four cartridges per magazine, providing unattended sAIT-1 backup capacities of 22TB native (57TB compressed); fully automates backups for an entire week, to the point each week when the magazines are removed for safe storage.

Added Tape Functions – Off-line Copy/Verify is available with no processor penalty.

High Transfer Rates – sAIT-1 native transfer rates up to 216GB/hour on Virtual Library models are increased to 562GB/hour with compression reducing time required for backups.

Fault-tolerant Backup and Restore – In the event of a drive failure within a mirrored module, the second drive will continue to operate, ensuring the backup is completed successfully.

Hardware Investment Protection – Highly scalable libraries feature multiple models that permit easy upgrades from one-drive to two-drive libraries or adding Mirrored Backup or Virtual Library Partitioning.

Key features

Virtual Library Partitioning – Cartridge slots can be assigned to a particular drive so the Midrange sAIT Library is divided into two partitions. Each partition can be assigned to a host server or LPAR; permits backup consolidation of two servers/partitions using one GST library.

Compliance Ready – WORM technology supports compliance with new government data storage regulations that apply to the tamperproof safeguarding of data.

LCD Display Panel – This multi-function LCD Display Panel continuously displays key drive, robotics and backup job conditions and allows a qualified operator to perform diagnostics.

Variable I/O Port – The VIOP is a separate tape I/O slot for importing and exporting individual tape cartridges and magazines under application control.

Inventory Sentry – Offline time is minimized with Inventory Sentry ensuring that cartridges or magazines have been inserted or removed when the I/O Door is opened.

Barcode Selective Restore – Barcode reader permits cartridge scanning and supports random access for selective restore from specified cartridges.

Secure Cartridge Removal – Host-controlled lockable I/O door prevents unauthorized inserting and removing of cartridges or magazines.

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

Reliability Features – Brushless DC motors turn lead screw-driven mechanisms; closed-loop servo controls all motions to provide absolute position accuracy in robotics.

Field-Replaceable Unit (FRU) Design – Many Midrange sAIT Library components are packaged in easily-installed FRUs requiring no wiring; Quick Swap drives, power supplies, controllers and robotics are easily removed/installed simplifying field servicing.

Small Footprint – Space-efficient size and light weight provides the best rackmount density for libraries available. Size: 12”h x 17”w x 32”d; weight: 150 lbs.

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
