A networking device that can send packets directly to a port associated with a
given network address in a Fibre Channel storage area network (SAN). The
Fibre Channel switches are used to expand the number of servers that can
connect to a particular storage port. Each switch is managed by its own
management software.
An assembly component that is designed to be replaced on site, without the
system having to be returned to the manufacturer for repair.
See field-replaceable unit
See host bus adapter (HBA).
As a function of the Sun StorageTek 6140 Array configuration, a representation
of a data host that is mapped to initiators and volumes to create a storage
domain. See also data
An I/O adapter that connects a host I/O bus to a computer's memory
system. Abbreviated HBA. 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.
See also initiator.
A group of hosts with common storage characteristics that can be mapped to
volumes. See also host.
The drive used by a controller to replace a failed disk. See also
System management traffic that uses the data path between a host and a
storage device. See also
A system component that initiates an I/O operation over a Fibre Channel (FC)
network. If allowed by FC fabric zoning rules, each host connection within the
FC network has the ability to initiate transactions with the storage array. Each
host in the FC network represents a separate initiator, so if a host is connected
to the system through two host bus adapters (HBAs), the system identifies two
different initiators (similar to multi-homed, Ethernet-based hosts). In contrast,
when multipathing is used in round-robin mode, multiple HBAs are grouped
together, and the multipathing software identifies the group of HBAs as a
single initiator.
A measure of transaction speed, representing the number of input and output
transactions per second.
