Spectra Logic T-Series Spectra T200 User Manual page 376

Glossary of Terms — D
CoD A capacity-on-demand feature of Spectra Logic libraries. Purchasing and
entering a key code in the library enables additional slots—chambers in the
Spectra T200, T380, and T680 library—allowing for additional storage
capacity.
Controller
Controller is another name for QIP; it is assigned to control each partition.
See also QIP.
D
DAS
Direct Attached Storage.
DBA Drive Bay Assembly. Each DBA can contain up to four drive sleds; it can
also contain one QIP for controlling the drives in that DBA. Each DBA
requires its own power supply (an N2 option is available). Each library can
hold up to three DBAs.
DHCP
Dynamic Host Configuration Protocol. A protocol for assigning dynamic
IP addresses to devices on a network. With dynamic addressing, a device
can have a different IP address every time it connects to the network. In
some systems, the device's IP address can even change while it is still
connected. DHCP also supports a mix of static and dynamic IP addresses.
E
EDU Endura Decryption Utilit. A command-line data decryption utility that can
be installed on any computer running the Linux operating system, to be
used if no Spectra library is available at time of data decryption and
restoration. To use EDU, attach the recommended two tape drives to the
Linux host running the utility, then use EDU to decrypt data from the
encrypted tape and write the decrypted data back to tape. If you have only
one tape drive, make sure that the Linux host has enough available disk
space to store the data as it's decrypted from the tape. Once the data is
decrypted and written to tape, it can then be restored using backup
software.
EE pool Entry/exit pool. A configurable number of slots (as chambers) used by
backup software for importing and exporting media.
EE port See TAP.
