GST’s Internal sAIT Tape Subsystem is part of our InternalDR™ family. sAIT tape technology provides high-performance in a basic GST backup solution for small to mid-sized servers. These models deliver high capacity, speed and reliability at cost-effective pricing to meet basic backup needs.

The Single sAIT Tape Subsystem can backup a wide variety of servers. They connect natively with a LVD (low voltage differential) interface.

Model Overview

GST’s Internal sAIT Tape Subsystem is available in a variety of models. sAIT technology is available in one server-to-SCSI Adapter interface:

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

sAIT Technology

Native 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

Compliance Ready – WORM technology plus 30-year shelf life cartridges comply with federal regulations stating how records are to be retained.

High Capacity – 1.3TB cartridge capacity simplifies large unattended backups, containing the backup on a single cartridge.

Performance – Speeds up to 281GB/hour dramatically shorten backups and restores.

Longevity – A Roadmap commits sAIT through 2010, ensuring investment protection in the technology and continued growth.

Reliability – Highest industry reliability ensures continued backup/restore operation.

Universality – Can be used on Unix, Linux, NT or the proprietary iSeries/AS/400 server platforms to ensure widest applicability.

Key features

WORM Enabled – Write Once Read Many (WORM) technology provides tamper-proof data protection with backup data stored on indelible, non-rewriteable and non-erasable media.

Capacity – 500GB native cartridge capacity supports large unattended backups. Capacity increases to 1.3TB using 2.6-to-1 compression.

Speed Factors – A 72MB buffer, 155,000 BPI linear recording density, 5,000 RPM recording drum and 2.6 compression ratio all deliver a native speed of 30MB/sec (108GB/hour) and compressed speed of 78MB/sec (281GB/hour).

Roadmap – sAIT technology's roadmap extends out four generations to SAIT-4 in 2010 with a 4TB cartridge capacity (10.4TB compressed) and 864GB/hour native (2.2TB compressed) speed.

Engineering – Quality designed in at the beginning, building onto sAIT's 500,000 hour Mean Time Between Failure (MTBF), 50,000 hours head-to-tape life and 30,000 end-to-end tape passes.

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.
