Quantum Scalar Intelligent Libraries SMI-S Reference Guide 91
LUN (Logical Unit Number)
A unique identifier used on a SCSI bus to distinguish between devices that share the same bus. SCSI is a
parallel interface that allows up to eight devices (target IDs) to be connected along a single cable. Each of
these eight devices has access to 16 unique address spaces (LUNs). A specified intersection of target ID
and target LUN can be construed as the Assigned LUN.
Mac address
An IEEE-defined globally unique address for Ethernet controllers. Short for “Universal LAN MAC Address.”
MAP (Maintenance Action Plan)
A CLI routine that guide a user through troubleshooting system or component error.
MCB (Management Control Blade)
A PCB that passes commands to and from the robotics control unit as well as to SAN components in order
to manage the Scalar i2000 intelligent library. All control modules have an MCB. No expansion module has
an MCB.
MIB (Management Information Base)
A database of objects that can be monitored by SNMP or other database management system.
NDMP
Network Data Management Protocol
NVRAM (Non-Volatile Random Access memory)
A type of memory that retains its contents when power is turned off.
Organizationally unique identifier
A number assigned to organizations by a recognized naming authority. It is part of the world wide name.
PCB (Printed Circuit Board)
A thin plate on which chips and other electronic components are placed. A board. A blade.
PIP (Power and Identification Processor)
A chip on an I/O blade.
POST (Power On Self Test)
A diagnostic testing sequence run by the SNC or MCB BIOS (basic input/output system) when the power is
initially turned on.
Point to Point
A Fibre Channel topology.
SAN (Storage Area Network)
A SAN is a dedicated, high-performance network whose primary purpose is the transfer of data along FC
or high-speed Ethernet connections between servers, interconnect devices, and storage peripherals.
SCSI (Small Computer System Interface)
A parallel interface standard.
SCSI Host
A virtual LUN mapping scheme for SCSI-attached hosts, allowing an overall LUN total of 256 devices to be
virtually remapped. For Scalar libraries other than the Scalar i2000, called VPM.
SFM (Scalar Firewall Manager)
A virtual LUN mapping scheme for Fibre Channel hosts, allowing an overall LUN total of 2048 devices to be
virtually remapped on a SAN-wide basis.
