One tray with drives, two controllers, fans, and power supplies. The
controller tray provides the interface between a host and a storage array.
The route used for communication of system management information,
usually an out-of-band connection.
See site LAN.
See direct attached storage
Any host that uses the system for storage. A data host can be connected
directly to the array (direct attach storage, or DAS) or can be connected to an
external switch that supports multiple data hosts (storage area network, or
SAN). See also host.
Provides tools that manage the data path I/O connections between the data
host and the storage array. This includes drivers and utilities that enable
storage management hosts to connect to, monitor, and transfer data in a
storage area network (SAN).
The route taken by a data packet between a data host and the storage device.
A storage architecture in which one or two hosts that access data are
connected physically to a storage array.
A physical drive component that stores data.
A notification of something that happened on a device. There are many
types of events, and each type describes a separate occurrence. See also
alarm and alert.
A tray that does not have a RAID controller, used to expand the capacity of
an array. This type of tray must be attached to a controller tray to function.
A set of contiguous blocks with consecutive logical addresses on a physical
or virtual disk.
The process of changing the data path automatically to an alternate path.
The percentage of faults detected against all possible faults or against all
faults of a given type.
FC See Fibre Channel
A set of standards for a serial I/O bus capable of transferring data between
two ports at up to 100 megabytes/second, with standards proposals to go to
higher speeds. Fibre Channel supports point to point, arbitrated loop, and
switched topologies. Fibre Channel was completely developed through
industry cooperation, unlike SCSI, which was developed by a vendor and
submitted for standardization after the fact.
