firmware
drive expansion module (DEM)
An optional library module that provide additional drive tray capacity and cartridge
storage.
dynamic World Wide Name (dWWN)
A feature that applies dynamic names to network devices rather than fixed names.
When a dWWN-named device is replaced, it is assigned the same WWN as the one
replaced, preventing reconfiguration of the network.
electronics control module (ECM)
The assembly that processes commands from a host system, coordinates the activities
of TallBots, CAPs, and tape drives, and Monitors status inputs from sensors and
switches.
Enterprise Library Software (ELS)
Enterprise Library Software (ELS) incorporates the StorageTek Nearline Control
Solutions (NCS) products, VTCS products, and provides customers with a single,
integrated software suite.
Enterprise Systems Connection (ESCON)
(1) A set of fiber-optic based products and services developed by IBM that allows
devices within a storage environment to be dynamically configured. A
channel-to-control unit I/O interface that uses optical cables as a transmission
medium.
(2) A set of IBM products and services that provide a dynamically-connected
environment within an enterprise.
Ethernet
A local-area, packet-switched network technology. See TCP/IP.
export
The action in which the library places a cartridge into the cartridge access port so that
the operator can remove the cartridge from the library. Synonymous with eject.
failover
The act of moving to a secondary or redundant path when the primary path fails.
FC-SCSI
A library connection type which uses small computer system interface over a physical
Fibre Channel interface.
Fibre Channel
A bidirectional, full-duplex, point-to-point, serial data channel structured for high
performance capacity. See FC-SCSI.
fibre connection (FICON)
An IBM S/390-based channel architecture that provides up to 256 channels in a single
connection, each having a capacity of 100 MB per second.
firmware
An ordered set of instructions and data stored in a way that is functionally
independent of main storage; for example, microprograms stored in a ROM.
