474 Glossary
picker
The robotic hand that handles cartridges.
point to point
A Fibre Channel topology that consists of a dedicated connection between two devices: a sending device
and a receiving device.
rackmount
An industry standard communication and computer equipment rack cabinet.
RAS (reliability, availability, and serviceability)
Three key attributes of computing system quality design. See reliability
, availability, and serviceability. An
infrastructure to support serviceability in order to identify, diagnose, and fix problems within the system. This
approach is designed to address the ability of service personnel and customers to diagnose and resolve
problems identified within the system. Additionally, configuration is addressed to support detection of
hardware configuration compatibility issues and persistence across FRUs.
RAS ticket
A ticket that alerts service personnel and customers of an issue with the library. RAS tickets identify which
library components are most likely causing the issue. When possible, a RAS ticket provides instructions for
resolving the issue.
reliability
A RAS attribute that is designed to prevent failure of a storage solution. See RAS
.
SAM (SCSI Architecture Model)
An ANSI standard that defines the generic requirements and overall framework in which other SCSI
standards are defined. New generations of this standard are identified by a numeric suffix; for example, the
second generation standard is SAM2.
SAN (storage area network)
A dedicated network that connects storage devices and servers in a pool, providing consolidated storage
and storage management. Storage interconnects between many initiators and target devices. The SAN
allows for sharing resources (target devices) among multiple servers (initiators).
SCSI (Small Computer System Interface)
A set of standards for a high-speed, parallel interface that connects processing devices to peripheral
devices, such as storage subsystems. The acronym is pronounced "scuzzy."
SCSI ID (Small Computer Systems Interface Address)
An address on a SCSI BUS. Typically there are 16 addresses on a single channel SCSI BUS.
server
A powerful, centralized computer (or program) designed to provide information to clients (smaller computers
or programs) upon request.
serviceability
A RAS attribute that refers to a component that is designed to accurately diagnose and report failures, as
well as minimize downtime in a storage solution. See RAS
.
setup wizard
A tool for initially configuring the library. It appears the first time the user starts the library. However, it can
be used to modify configurable items anytime after the initial configuration.
sled
See UDS
.
SMI-S (Storage Management Initiative Specification)
An industry standard SMI-S application programming interface (API) developed by SNIA that facilitates the
management of multi-vendor devices in a storage area networks (SANs) environment.
