dual-redundant configuration
A controller configuration consisting of two active controllers operating as a single controller.
If one controller fails, the other controller assumes control of the failing controller devices.
Ethernet
A standard network protocol that operates mostly on a physical level, using network
interface cards and cabling to transmit data between computers. Transfer rates are normally
10 or 100 megabits per second.
fabric
Multiple Fibre Channel switches interconnected and using Fibre Channel methodology for
linking nodes and routing frames in a Fibre Channel network.
failback
1. The process that takes place when a previously failed controller is repaired or replaced and
reassumes the workload from a companion controller.
2. The process that takes place when the operation of a previously failed cluster group moves
from one cluster node back to its primary node.
failover
1. The process that takes place when one controller in a dual-redundant configuration
assumes the workload of a failed companion controller. Failover continues until the failed
controller is repaired or replaced.
2. The process that takes place when the operation of a cluster group moves from one cluster
node to another node in the same cluster.
FC-AL
The Fibre Channel Arbitrated Loop standard. See arbitrated loop. See Fibre Channel.
FC-SW
Fibre Channel Switched Topology and Switch Controls.
Fibre Channel
An IEEE standard for providing high-speed data transfer among workstations, mainframes,
supercomputers, desktop computers, storage devices, and display devices.
