EBCDIC

Abbreviation of Extended Binary-Coded Decimal Interchange Code. Pronounced eb-sih-dik, EBCDIC is an IBM® code for representing characters as numbers. Although it is widely used on large IBM® computers, most other computers, including PCs and Macintoshes®, use ASCII codes. See also ASCII, binary, synchronous, and asynchronous.

Electronic vaulting

The transfer of data to an offsite storage facility via a communication link rather than via portable media. Typically, electronic vaulting is used for batch or journaled updates to critical files to supplement full backups that are taken periodically.

ESA/390®

Enterprise Systems Architecture/390®. Often abbreviated S/390®, ESA/390® is an IBM® architecture for mainframe computers and peripherals. Processor systems that follow this architecture include the IBM ES/9000® family. In 2000, IBM® changed the server series name to eServer zSeries.

ESCON®

Enterprise Systems Connection architecture is an IBM® mainframe ESA/390® computer peripheral interface or connection between two mainframes for data exchange. The I/O interface utilizes ESA/390® logical protocols over a serial interface that configures attached units to a communication fabric. ESCON® is based on networking technology. ESCON® provides direct channel-to-channel connections between mainframe systems over fiber-optic links at distances up to 43 kilometers or 25 miles. ESCON® also provides a way for communication controllers and other devices to share a single channel to a mainframe.

ESCON Director

An I/O interface switch that allows the interconnection of multiple ESCON® interfaces in a distributed-star topology.

Ethernet

A Local Area Network (LAN) protocol developed by Xerox® in cooperation with Digital Equipment and Intel in 1976. Ethernet supports a star or bus topology and supports a data transfer rate of 10 megabits per second or 10 Mbps. The Ethernet specification formed the basis of the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method for handling simultaneous demands and is one of the most widely implemented LAN standards. Ethernet is also known as 10BaseT. See also Fast Ethernet, Gigabit Ethernet.

Fabric

A group or network of switches arranged in such a way as to enhance scalability and connectivity.

With Hitachi LUN Manager, open systems Logical Units LUNs can be defined, configured, and maintained. There is no more waiting for the hardware vendor to come and make configuration changes. Hitachi LUN Manager includes an easy-to-use, GUI-basedinterface that allows the easy definition of paths for LUNs, the reconfiguration of LUN-to-portassignments, or the viewing of the Lightning 9900 remote service information messages. Because the Hitachi LUN Manager can assign multiple paths to a single LUN, support of alternate path failover, path load balancing, and clustered systems is possible. Running on a standard Windows-basedPC connected to the storage subsystems by a dedicated LAN, Hitachi LUN Manager can support up to eight Lightning 9900 systems Hitachi CruiseControl Hitachi Data SystemsHitachi SANtinel Storage MaximizerHitachi Data Systems Professional Services Overview Professional Services and SupportData Protection Services Cost of Risk Analysis methodology CORARemote Copy Assessment and Implementation Service Data Protection Services LabHitachi NanoCopy Implementation Service Hitachi Data SystemsContinuous Availability Service Professional Services and SupportOn-lineData Migration Service SAN servicesHitachi Data Systems Software Portfolio Review and Analysis Servicethe Performance Experiment System Configurations forThe 7700E used all 6GB drives Hitachi Data Systems10BaseT Glossary of Terms100BaseT ACP pairAvailability Hitachi Data SystemsBack end Business Continuity Planning BCPCARB GlossaryCache CHIPConsistency Groups Hitachi Data SystemsControl Frame CORA Cost of Risk AnalysisGlossary Disaster RecoveryData Duplication Data MigrationEBCDIC Hitachi Data SystemsElectronic vaulting ESA/390Failover GlossaryFast Ethernet Fast writeHitachi Data Systems File BackupFICON Front EndGlossary Hitachi FlashAccessHDmS Hitachi CruiseControlHitachi Data Systems Hitachi Multiplatform Backup/RestoreHitachi InstantSplit Hitachi LUN ManagerGlossary Hitachi Rapid RecoveryHitachi Resource Manager Hitachi SANtinelHXRC Hitachi Extended Remote Copy Hitachi Data SystemsHYPERtape JavaGlossary Logical VolumeLightning 9900 Series Logical UnitMBCP Hitachi Data SystemsMIPS Meta-dataMTBF GlossaryMTTR NanoCopyOn-linesystem Hitachi Data SystemsOpen system Operating SystemGlossary Recovery TimeRAID RAID ControllersHitachi Data Systems SwitchSCSI SnapshotVolume Virtual Logical Volume Image ManagerGlossary SynchronousWorkload Hitachi Data SystemsWarm site Corporate Headquarters Hitachi Data Systems Worldwide OfficesAsia Headquarters Australia/New Zealand Headquarters
