complex programmable logic device See CPLD. Configuration See CAPI. Application Programming Interface controller A (or B) A short way of referring to controller module A (or B). controller enclosure An enclosure that contains one or two controller modules. controller module A FRU that contains the following subsystems and devices: an SC processor; an MC processor; a SAS expander and an EC processor; management interfaces; cache protected by a supercapacitor pack and nonvolatile memory (CompactFlash); host, expansion, network, and service ports; and midplane connectivity. In a controller enclosure, the upper controller module is designated A and the lower one is designated B. converged network controller A controller module whose host ports can be set to operate in FC or iSCSI mode. Changing the host-port mode is also known as changing the ports' personality. Coordinated Universal See UTC. Time CPLD Complex programmable logic device. An electronic component used to build reconfigurable digital circuits. It can replace large numbers of logic gates. CQL CIM Query Language. CRC Cyclic Redundancy Check. A mathematical algorithm that, when implemented in software or hardware, can be used to detect errors in data. CSV Comma separated values. A format to store tabular data in plain-text form. Cyclic Redundancy Check See CRC. DAS Direct Attached Storage. A dedicated storage device that connects directly to a host without the use of a switch. Data Encryption Standard See DES. dedicated spare A disk that is reserved for use by a specific vdisk to replace a failed disk. See also available disk, compatible disk, dynamic spare, and global spare. default mapping Host-access settings that are configured when a volume is created, and that apply to all hosts that are not explicitly mapped to that volume using different settings. See also explicit mapping and masking. DES Data Encryption Standard. An algorithm for the encryption of electronic data. DHCP Dynamic Host Configuration Protocol. A network configuration protocol for hosts on IP networks. Direct Attached Storage See DAS. Distributed Management Task Force See DMTF. DMTF Distributed Management Task Force. An industry organization that develops and maintains standards for system management. drive enclosure An enclosure that contains one or two expansion modules. Drive enclosures can be connected to a controller enclosure to provide additional storage capacity. drive spin down See DSD. DRM Disaster recovery management. Storage-system firmware features that, when the Site Replication Adapter (SRA) feature is enabled, support the use of VMware's Site Recovery Manager to automate disaster-recovery failover and failback tasks. See also SRA. 74 Glossary
