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).
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 Storage 2500-M2 Arrays configuration, a
representation of a data host that is mapped to initiators and volumes to
create a storage domain. See also
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
hot-spare.
A module in the expansion tray that monitors the status of the components.
An IOM also serves as the connection point to transfer data between the
expansion tray and the controller.
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) or iSCSI Ethernet network. If so configured, each host connection
within the network has the ability to initiate transactions with the storage
array. Each host in the network represents a separate initiator, so if a host is
connected to the system through two host bus adapters (HBAs) or NICs, 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 or NICs are grouped together, and the multipathing
software identifies the group as a single initiator.
A measure of transaction speed, representing the number of input and
output transactions per second.
