logical unit number (LUN)
The SCSI identifier for a volume as it is recognized by a particular host. The same
volume can be represented by a different LUN to a different host.

MAC address
See media access control (MAC) address.
management host
A Solaris host serving the configuration, management, and monitoring software for
the Sun StorageTek 2500 Series array. The software on the station can be accessed
with a browser to run the browser interface or with a remote scripting command-line
interface (CLI) client to access the SSCS CLI commands.
master / alternate master
A design for reliability that uses redundant configuration. Array configurations share
master/alternate master configurations: each array configuration has two controller
trays that are grouped as one host. In each case, the master component uses the IP
address and name. If the master fails, the alternate master assumes the IP address
and name and takes over the master’s functions.
media access control (MAC) address
The physical address identifying an Ethernet controller board. The MAC address,
also called an Ethernet address, is set at the factory and must be mapped to the IP
address of the device.
mirroring
A form of storage – also called RAID Level 1, independent copy, and real-time copy –
whereby two or more independent, identical copies of data are maintained on separate
media. Typical mirroring technologies enable the cloning of data sets to provide
redundancy for a storage system.
multipathing
A design for redundancy that provides at least two physical paths to a target.
out-of-band traffic
System management traffic outside of the primary data path that uses an Ethernet
network. See also in-band traffic.
PDU
See power distribution unit (PDU).
