SCSI
■ Small Computer System Interface. An American National Standards Institute (ANSI)
interface which defines the physical and electrical parameters of a parallel I/O bus used
to connect computers and a maximum of 16 bus elements.
■ The communication protocol used between a controller pair and the hosts. Specifically,
the protocol is FC-AL or SCSI on a Fibre Channel. SCSI is the higher command-level
protocol and Fibre Channel is the low-level transmission protocol. The controllers have
full support for SCSI-2; additionally, they support some elements of SCSI-3.
SCSI-3
The ANSI standard that defines the operation and function of Fibre Channel systems.

SMART
Self-Monitoring, Analysis, and Reporting Technology. An industry standard for running
internal diagnostics on disk drives and making predictive failure analysis. If a physical disk
drive reports an imminent failure, the controllers redistribute data to other drives. The
SMART message is reported and should trigger the immediate corrective action to replace
the drive.
snapshot
A temporary virtual disk (VD) that reflects the contents of another virtual disk at a
particular point in time. A snapshot operation is done only on an active virtual disk. Only
one snapshot of an active virtual disk can exist at any point. The active disk and its snapshot
constitute a virtual family.
See also active virtual disk, virtual disk copy, and virtual disk family.
SSN
Storage System Name. A Command View EVA-assigned, unique 20-character name that
identifies a specific storage system.
storage pool
The aggregated blocks of available storage in the total physical disk array.
storage system
The controllers, storage devices, enclosures, cables, and power supplies and their software.
Storage System Scripting Utility (SSSU)
A command-line application supplied in the host operating system kits that allows for
control of the Enterprise Virtual Array.
