failover
The process by which the controller rebuilds data onto a spare disk
drive when a disk drive that is part of a redundant array fails.
When a storage system is in active-active mode, failover is the act
of temporarily transferring ownership of controller resources from
a failed controller to a surviving controller. The resources include
disk arrays, cache data, and host ID information.
FC device
A device that uses fibre channel (FC) communications. This
technology currently supports both copper and optical cabling
with speeds of 1 Gbps and 2 Gbps.
FC port
The connector on a router or device that provides a connection to a
fibre channel (FC) network.
fibre
A generic fibre channel (FC) term that refers to all transmission
media types specified in the FC Physical Layer standard (FC-PH),
such as optical fiber, copper twisted pair, and copper coaxial cable.
fibre channel (FC)
A bidirectional, point-to-point serial data channel, structured for
high-performance capability. In the physical sense, FC is an
interconnection of multiple communication points, called N_Ports,
by a switching network (fabric). FC transports incoming data from
devices by reading the buffer information, packaging it, and
sending the information across the fabric. Although FC is a
generalized transport mechanism that has no protocol of its own
or native I/O command set, it can transport any existing upper-
level protocol such as SCSI and IP. FC offers high-speed data
transfer rates up to 2 Gbps. FC is most commonly used to connect
clustered servers to storage systems. ANSI has developed
standards for FC.
file system
A layer of software that manages a collection of files within a
directory structure. Storage Manager Pro supports three types of
file systems on Windows NT/2000 systems: FAT, NTFS, and FAT32
(Windows 2000 only).
