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.
SCSI-3 Enclosure Services
See SES.
selective presentation
The process whereby a controller presents a virtual disk only to the host computer authorized
access.
serial transmission
A method of transmission in which each bit of information is sent sequentially on a single
channel rather than simultaneously as in parallel transmission.
SES
SCSI-3 Enclosures Services. Those services that establish the mechanical environment,
electrical environment, and external indicators and controls for the proper operation and
maintenance of devices within an enclosure.

Snapclone
A virtual disk that can be manipulated while the data is being copied. Only an Active member
of a virtual disk family can be snapcloned.
The Snapclone, like a snapshot, reflects the contents of the source virtual disk at a particular
point in time. Unlike the snapshot, the Snapclone is an actual clone of the source virtual disk
and immediately becomes an independent Active member of its own virtual disk family.
