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 Management See SMI-S. Initiative - Specification Storage Management See SMU. Utility Storage Networking See SNIA. Industry Association 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. Glossary 183
