- The
TN2211 Optical Drive has replaced the TN1656 Tape Drive in DEFINITY
ECS R8r and later systems.
-
The drive provides removable storage for software upgrades, translation
backups, announcement file backups, core dumps, etc., as did the
TN1656 Tape Drive.
- The
Optical Drive has several advantages over the TN1656 Tape Drive:
- Writing
to the optical disk is considerably shorter than writing to tape.
- A
full backup will take approximately 20 minutes, whereas the tape
drive takes up to 95 minutes.
- Writing
to the optical disk is more reliable due to: block allocation
(has several spare blocks available)
number of accesses to the media
- The
UN332C MSSNET must be used with the TN2211.
