StorageTek® T9940 Tape Drive
The StorageTek T9940 "capacity-centric"
tape drive offers exceptional storage capacity for business applications
such as growing archive, backup, record-retention and disaster recovery
needs. The ultra-reliable T9940 offers a superior combination of
capacity, speed and robustness, in a compact and economical package.
- A massive 60 gigabyte (native) capacity per
cartridge. With compression this typically means 120 to 240 or
more gigabytes on a
- single piece of media. Store a petabyte (1000
terabytes) in a single StorageTek automated tape library.
- 10 megabytes per second native (up to 37 megabytes
compressed)
- Heterogeneous attachment via ESCON, SCSI and
native Fibre Channel connectivity - provides SAN readiness.
- Advanced engineering componentry and packaging
provide the best in data reliability and availability, together
with robustness for exceptionally high duty-cycles.

| Individual compression achieved
is a function of many variables, including the data characteristics.
For example, scientific data usually compresses less than
general business data. As a practical guide, mainframe
(MVS/ESCON) compression rates are typically 4:1, while
client server operating systems (UNIX/NT on SCSI or Fibre)
usually achieve in the 2:1 to 2.5:1 range. In all instances,
slightly lower or significantly higher numbers may be
achieved. |
