LUN Logical Unit Number or logical unit. A system assigned number that allows
host software to differentiate multiple logical units within the same system.
LUN mapping The process of changing the logical unit number that is presented from storage.
LUN masking The characteristic that enables an administrator to dynamically expose or hide
logical units from specific HBA ports. This provides an individual server or
multiple servers access to an individual logical unit or multiple logical units
and prohibits unwanted server access to the same logical units.
MAC address Media access control. A unique address that identifies an Ethernet device.
NTC Network terminal concentrator. A modem connection point for the Sun
StorEdge Remote Response software. The NTC facilitates a point-to-point
protocol (PPP) connection from a remote support and does not depend on the
Storage Service Processor to complete a call.
OPIE one-time passwords in everything. OPIE is a package derived from the Bellcore
S/Key Version 1 distribution that secures a system against replay attacks.
out-of-band Refers to the connections that go over Ethernet and not Fibre Channel. This
connection is not in the data path. The Storage Service Processor does not have
access to the data that is stored on the Sun StorEdge 6320 system; thus this
information is considered to be out-of-band.
N port A Fibre Channel port in a point-to-point or Fabric connection.
RAID Redundant array of independent disks. A configuration in which multiple
drives are combined into a single virtual drive to improve performance and
reliability.
RARP Reverse address resolution protocol. A protocol in the Solaris operating
environment that enables automatic assignment of the array IP address from
the host.
RU Rack unit.
SCSI Small Computer Systems Interface. An industry standard for connecting disk
and tape devices to a host.
storage array One or more trays with at least one being a controller tray. All the trays are
managed as a single unit.
storage pool A group of volumes that can be disks. From the volumes, you can create
virtual drives.
Storage Service
Processor LAN An Ethernet LAN used to perform local management and service functions on
the Storage Service Processor. It also facilitates aggregation of telemetry data
from multiple Storage Service Processors. By design, the Storage Service
Processor LAN address is configured to be 10.0.0.n.
