Each magazine has a barcode label that the scanner reads for identification and inventory. An
optional, snap-on dust cover is available for the magazines. Magazines with the dust cover have
interlocked stacking that enables easier storage of the media when they are removed from the library
for external storage.
Support for WORM
The ESL G3 library supports WORM (write once, read many) technology in LTO-4 and LTO-5 tape
drives. WORM requirements include:
• Cartridges
• Firmware
• WORM-supported LTO-4 tape drives
• WORM-supported LTO-5 tape drives
WORM allows non-erasable data to be written once and provides extra data security by prohibiting
accidental data erasure. When the library firmware and WORM-supported LTO-4 or LTO-5 tape drive
code are installed on a library with LTO-4 or LTO-5 tape drives, the WORM feature is supported
whenever the operator uses WORM cartridges.
Tape Drives
Tape drives are enclosed in a universal drive sled. You can hot swap and hot add all supported
drives, regardless of type. The library supports HP LTO-4 and LTO-5 FC Multi-mode tape drives.
The control module and expansion modules have upper and lower drive clusters. Each library must
have at least one tape drive. Each drive cluster can house up to six tape drives for a total of 12 drives.
Additional drives can be added to the first seven expansion modules in the configuration. This enables
you to have a total of 96 drives.
NOTE:
When you add drives, you lose storage slots.
