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
