IOPS A measure of transaction speed, representing the number of input and output
transactions per second.
LAN Local area network.
logical unit (LUN) The 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.
LUN See logical unit (LUN) .
LUN mapping Assigning volume permissions to an initiator.
LUN masking Filtering the initiators that have access to a particular volume.
MAC Address See media access control (MAC) address .
management host A host with an out-of-band network connection to the system that is used to
manage the system. A management host can have monitoring software
installed, such as a remote CLI package, Sun StorEdge Enterprise Storage
Manager or Sun Storage Automated Diagnostic Environment (Device Edition),
or a third-party monitoring program. A management host can also be used to
run management software on another machine through a network connection.
management interface
card (MIC) The card on which the management software resides. Each Data Services
Platform has two MICs, which operate in a master/alternate master mode.
master / alternate
master A design for reliability that uses redundant configuration. Array configurations
and the management interface cards (MICs) have master/alternate master
configurations: each array configuration has two controller trays but only one
IP address and name, and the MICs share one IP address and name. 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.
MIC See management interface card (MIC) .
multipathing A design for redundancy that provides at least two physical paths to a target.
network domain A LAN that is used for a special purpose such as internal communication. Each
storage system can be part of up to three LANs; that is, it can be configured in
one of three types of network domains.
NSCC Network Storage Command Center, the destination for the data collected by
the Sun Service Remote Response service about Sun systems. When this feature
is enabled for a system, the system is monitored remotely.
