Term Definition
SBB Storage Bridge Bay. A specification that standardizes physical, electrical, and enclosure-
management aspects of storage enclosure design.
SC Storage Controller. A processor (located in a controller module) that is responsible for RAID
controller functions. The SC is also referred to as the RAID controller. See also EC, MC.
secondary system The storage system that contains a replication set’s secondary volume. See also replication
set, primary system.
secondary volume The volume that is the destination for data in a replication set and that is not accessible to
hosts. The secondary volume exists in a secondary (linear storage) or pool (virtual storage) in
a secondary storage system.
secret For use with CHAP, a password that is shared between an initiator and a target to enable
authentication.
SED Self-encrypting drive. A disk drive that provides hardware-based data encryption and supports
use of the storage system’s Full Disk Encryption feature. See also FDE.
SEEPROM Serial electrically erasable programmable ROM. A type of nonvolatile (persistent if power
removed) computer memory used as FRU ID devices.
SES SCSI Enclosure Services. The protocol that allows the initiator to communicate with the
enclosure using SCSI commands.
SFCB Small Footprint CIM Broker.
SFF Small form factor.
SFTP SSH File Transfer Protocol. A secure secondary interface for installing firmware updates,
downloading logs, and installing security certificates and keys. All data sent between the client
and server will be encrypted.
SHA Secure Hash Algorithm.
shelf See enclosure.
sideplane A printed circuit board to which components connect longitudinally within an enclosure.
SLP Service Location Protocol. Enables computers and other devices to find services in a local area
network without prior configuration.
SMART Self-Monitoring Analysis and Reporting Technology. A monitoring system for disk drives that
monitors reliability indicators for the purpose of anticipating disk failures and reporting those
potential failures.
SMC Storage Management Console. The web application that is embedded in each controller
module and is the primary management interface for the storage system.
SMI-S Storage Management Initiative - Specification. The SNIA standard that enables interoperable
management of storage networks and storage devices.
The interpretation of CIM for storage. It provides a consistent definition and structure of data,
using object-oriented techniques.
SMI-S is not supported for a system with 5U84 enclosures.
snapshot A point-in-time copy of the data in a source volume that preserves the state of the data as it
existed when the snapshot was created. Data associated with a snapshot is recorded in both
the source volume and in its associated snap pool. A snapshot can be mapped and written
to. Snapshots that can be mapped to hosts are counted against the snapshot limit, whereas
transient and unmappable snapshots are not.
snapshot tree A group of virtual volumes that are interrelated due to creation of snapshots. Since snapshots
can be taken of existing snapshots, volume inter-relationships can be thought of as a “tree” of
volumes. A tree can be 254 levels deep. See also base volume, child volume, parent volume,
source volume.
