Glossary 183
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.
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.
SMU Storage Management Utility. The web application that is embedded in each controller
module and is the primary management interface for the storage system.
snap pool A volume that stores data that is specific to snapshots of an associated master volume,
including copy-on-write data and data written explicitly to the snapshots. A snap pool
cannot be mapped.
snapshot A “virtual” volume that preserves the state of a master volume’s data as it existed when the
snapshot was created. Data associated with a snapshot is recorded in both the master
volume and in its associated snap pool. A snapshot can be mapped and written to. The
capability to create snapshots is a licensed feature. A base of 64 snapshots is included with
all 1040 systems without an additional license. Snapshots that can be mapped to hosts are
counted against the snapshot-license limit, whereas transient and unmappable snapshots
are not.
SNIA Storage Networking Industry Association. An association regarding storage networking
technology and applications.
SRA Storage Replication Adapter. A host-based software component that allows VMware’s Site
Recovery Manager to manage the storage-system firmware’s disaster recovery management
(DRM) features, automating disaster-recovery failover and failback tasks. The SRA uses the
CLI XML API to control the storage system. See also DRM.
SSH Secure Shell. A network protocol for secure data communication.
SSL Secure Sockets Layer. A cryptographic protocol that provides security over the internet.
Storage Controller See SC.

storage system A controller enclosure with at least one connected drive enclosure. Product documentation
and interfaces use the terms storage system and system interchangeably.
syslog A protocol for sending event messages across an IP network to a logging server.
UCS Transformation
Format - 8-bit
See UTF-8.
ULP Unified LUN Presentation. A RAID controller feature that enables a host to access mapped
volumes through any controller host port. ULP incorporates Asymmetric Logical Unit Access
(ALUA) extensions.
Unified LUN
Presentation
See ULP.
unmount To remove access to a volume from a host OS. Synonyms for this term include unpresent
and unmap.
unwritable cache data Cache data that has not been written to disk and is associated with a volume that no longer
exists or whose disks are not online. If the data is needed, the volume’s disks must be
brought online. If the data is not needed it can be cleared, in which case it will be lost and
data will differ between the host and disk. Unwritable cache data is also called orphan
data.
