Glossary

A

ACSLS See Automated Cartridge System Library

Software.

agent A software entity that runs on endpoints

and provides management capability for other

hardware or software. An example is an Simple

Network Mail Protocol (SNMP) agent. An agent has

the ability to spawn other processes.

AL See arbitrated loop.

allocated storage The space that is allocated to

volumes, but not assigned.

allocation The process of obtaining a volume and

unit of external storage, and setting aside space on

that storage for a data set.

arbitrated loop (AL) A Fibre Channel

interconnection technology that allows up to 126

participating node ports and one participating fabric

port to communicate. See also Fibre Channel

Arbitrated Loop and loop topology.

array An arrangement of related disk drive

modules that have been assigned to a group.

Automated Cartridge System Library Software

(ACSLS) Functions as a central service provider

for StorageTek library operations in heterogeneous

environments. It allows you to collapse disparate,

application-dedicated libraries to one centralized

library or string of libraries accessed via a single

point of control.

B

bandwidth A measure of the data transfer rate of

a transmission channel.

bridge Facilitates communication with LANs,

SANs, and networks with dissimilar protocols.

C

CIM See Common Information Model.

CIM agent The code that is comprised of common

building blocks that can be used instead of

proprietary software or device-specific

programming interfaces to manage Common

Information Model (CIM)-compliant devices. A CIM

agent is made up of agent code, a CIM object

manager (CIMOM), client application device, device

provider, and Service Location Protocol.

CIM object manager (CIMOM) The common

conceptual framework for data management that

receives, validates, and authenticates the CIM

requests from the client application. It then directs

the requests to the appropriate component or

service provider.

CIMOM See CIM object manager.

client A function that requests services from a

server and makes them available to the user. A

term used in an environment to identify a machine

that uses the resources of the network.

client application A storage management

program that initiates CIM requests to the CIM

agent for the device.

client authentication The verification of a client

in secure communications where the identity of a

server or browser (client) with whom you want to

communicate is discovered. A sender’s authenticity

is demonstrated by the digital certificate issued to

the sender.

client-server relationship Any process that

provides resources to other processes on a

network is a

server. Any process that employs

these resources is a

client. A machine can run

client and server processes at the same time.

Client System Component (CSC) A term used in

a STK ACSLS environment. It provides a seamless

connection between backup applications and

ACSLS manager software.

Client System Interface (CSI) A term used in a

STK ACSLS environment. The interface to the CSC

on an ACSLS server.
