Glossary array bandwidth CHAP data migration DMS EVA fabric FC FCIP FCoE Fibre Channel A storage system that contains multiple disk or tape drives. A disk array, for example, is differentiated from a disk enclosure, in that the array has cache memory and advanced functionality, like RAID and virtualization. Components of a typical disk array include disk array controllers, cache memories, disk enclosures, and power supplies. A measure of the volume of data that can be transmitted at a specified transmission rate. A 1-Gbps/2-Gbps Fibre Channel port can transmit or receive at nominal rates of 1- or 2-Gbps, depending on the device to which it is connected. This corresponds to actual bandwidth values of 106 MB and 212 MB, respectively. Challenge Handshake Authentication Protocol. A protocol that defines a methodology for authenticating initiators and targets. The process of transferring data between storage types, formats, or computer systems. Data migration is usually performed programmatically to achieve an automated migration, freeing up human resources from tedious tasks. Migration is a necessary action for retaining the integrity of the data and for allowing users to search, retrieve, and make use of data in the face of constantly changing technology. Data migration service. A technology that simplifies data migration jobs with minimum downtime while providing protection against common user errors. Enterprise Virtual Array. The EVA Cluster aggregates multiple EVA subsystems into a single system image and a single point of management. It allows for the pooling and sharing of storage resources to improve efficiency, simplify operations, and improve availability over individual storage subsystems. A fabric consists of cross-connected Fibre Channel devices and switches. Fibre Channel. High-speed serial interface technology that supports other higher layer protocols such as SCSI and IP, and is primarily used in SANs. Standardized under ANSI in 1994. Fibre Channel over Internet Protocol. An Internet Protocol-level storage networking technology. FCIP mechanisms enable the transmission of Fibre Channel information by tunneling data between SAN facilities over IP networks. This facilitates data sharing over a geographically distributed enterprise. Fibre Channel over Ethernet. An encapsulation of Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks while preserving the Fibre Channel protocol. For more information, visit www.fcoe.com. See FC. MPX200 Multifunction Router User Guide 273
