I/O
An adapter that connects a host I/O bus to a computer's memory
system. Host bus adapter is the preferred term in SCSI contexts.
Adapter and NIC are the preferred terms in Fibre Channel contexts. The
term NIC is used in networking contexts such as Ethernet and token
ring. (SNIA)
A host-interface port on a controller module or an expansion module.
A dual-controller Fibre Channel enclosure includes host port
interconnect circuitry which can be used to connect the host ports on
the upper controller module to those on the lower controller module.
When enabled, the port interconnect gives each host access to all the
volumes assigned to both controllers and makes it possible to create a
redundant configuration without using an external FC switch. The port
interconnect should only be enabled when the system is used in direct
attach configurations. When using a switch attached configuration, the
port interconnect must be disabled.
The ability to remove and replace a FRU while the system is powered
on and operational.
Transmission of a protocol other than the primary data protocol over
the same medium as the primary data protocol. Management protocols
are a common example of in-band transmission. (SNIA)
This type of access is available through use of the Configuration API
(CAPI) to develop a programmed interface.
An operating mode in which a pair of controllers can process host I/Os
and share disk channels but cannot fail over and assume responsibilities
of a failed controller, because no mirroring of write-back cache occurs.
The process of writing a specific pattern to all data blocks on all disk
drives in a virtual disk. This process overwrites and destroys existing
data on the disk drives and the virtual disk. Initialization is required to
make the entire virtual disk consistent at the onset. Initialization
ensures that virtual-disk verifications performed in the future are
executed correctly.
