Our Dual LTO Tape Subsystem is part
of GST’s SafeDR™ family. Dual drives 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
backup operations.
The Dual LTO Tape Subsystem can backup a wide variety of servers.
They connect natively with LVD (low voltage differential),
HVD (high voltage differential), and FC (Fibre Channel) interfaces.
GST’s Dual LTO Tape Subsystem is available in a variety
of models. Each LTO technology (LTO-1, LTO-2, LTO-3, LTO-4)
is available in two server-to-SCSI Adapter interfaces and
one fibre interface:
. Maximum SCSI negotiation
of 160MB/s; the total server-to-storage peripheral connectivity
is 12 meters.
. Maximum SCSI negotiation
of 40MB/s; the total server-to-storage peripheral connectivity
is 25 meters.
. 2Gbit fibre interface
LTO tape technologies supported are LTO-1, LTO-2, LTO-3 and
the newer LTO-4. Native capacities for LTO-1, LTO-2, LTO-3
and LTO-4 are 100GB, 200GB, 400GB and 800GB (200GB, 400GB,
800GB, 1.6TB compressed) with speeds of 54GB/hr, 126GB/hr,
288GB/hr and 432GB/hr (108GB/hr, 252GB/hr, 576GB/hr, 864GB/hr
compressed).
Cartridges use linear (serpentine)
tape format providing fewer moving parts, durability and reduced
maintenance costs. The version of LTO technology that GST
uses is best suited for high-capacity backup, restore and
archiving. Enhancements in the areas of timing-based servos,
hardware data compression, optimized track layouts and ECC
error correction help improve capacities, performance and
reliability.
– Mirrored backup capability produces simultaneous
sets of identical backup cartridges with no performance
penalty; this permits storage of one set off-site for better
disaster recovery and storage of the other set on-site for
rapid restore.
– Dual-drive configurations ensure
against drive failure since the second drive continues to
operate, ensuring the backup is completed successfully.
–
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
(doubling capacity).
–
The small dimensions and light weight of the configuration
facilitate the optimum use of datacenter space.
– For IT sites with an investment in LTO-1, LTO-2
and LTO-3 media, the newer LTO-4 technology is backward-read
compatible, and forward-read compatible with future generations.
– Manages mirroring, off-line
copying, cascading, and the LCD Display Panel.
– Multi-function LCD Display
Panel continuously displays key drive and backup job conditions.
– RS232 interface for updating
firmware and optimizing drive performance.
– 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.
– Purchase price includes a built-in manufacturer’s
warranty of three years.
