extent A unit of data that manages the mapping of data between managed disks
and virtual disks.
F
failover
In SAN Volume Controller, the function that occurs when one redundant
part of the system takes over the workload of another part of the system
that has failed.
FC See fibre channel .
fibre channel
A technology for transmitting data between computer devices at a data
rate of up to 4 Gbps. It is especially suited for attaching computer servers
to shared storage devices and for interconnecting storage controllers and
drives.
FlashCopy mapping
A relationship between two virtual disks.
G
GBIC See gigabit interface converter .
gigabit interface converter (GBIC)
An interface module that converts the light stream from a fibre-channel
cable into electronic signals for use by the network interface card.
H
HBA See host bus adapter .
host bus adapter (HBA)
In SAN Volume Controller, an interface card that connects a host bus, such
as a peripheral component interconnect (PCI) bus, to the storage area
network.
host ID
In SAN Volume Controller, a numeric identifier assigned to a group of host
fibre-channel ports for the purpose of logical unit number (LUN) mapping.
For each host ID, there is a separate mapping of Small Computer System
Interface (SCSI) IDs to virtual disks (VDisks).
host zone
A zone defined in the storage area network (SAN) fabric in which the
hosts can address the SAN Volume Controllers.
I
inconsistent
In a Global Mirror relationship, pertaining to a secondary virtual disk
(VDisk) that is being synchronized with the primary VDisk.
input/output (I/O)
Pertaining to a functional unit or communication path involved in an input
process, an output process, or both, concurrently or not, and to the data
involved in such a process.
Internet Protocol (IP)
In the Internet suite of protocols, a connectionless protocol that routes data
