SilkWorm 3800 Hardware Reference
A loop created using the Brocade QuickLoop application. A QuickLoop allows
private devices within the loop to communicate with public and private devices
across the fabric, and can contain a number of devices or looplets.
May also refer to the Brocade QuickLoop product.
Resource allocation time-out value. The maximum time a frame can be delayed in
the fabric and still be delivered. See also E_D_TOV, RR_TOV.
Redundant array of independent disks. A collection of disk drives that appear as a
single volume to the server and are fault tolerant through mirroring or parity
checking. See also JBOD.
The rate at which requests arrive at a servicing entity. See also service rate.
As applies to a fabric, the communication path between two switches. May also
apply to the specific path taken by an individual frame, from source to
destination. See also FSPF.
The assignment of frames to specific switch ports, according to frame destination.
Resource recovery time-out value. The minimum time a target device in a loop
waits after a LIP before logging out a SCSI initiator. See also E_D_TOV,
R_A_TOV.
Registered state change notification. A switch function that allows notification of
fabric changes to be sent from the switch to specified nodes.
Storage area network. A network of systems and storage devices that
communicate using fibre channel protocols. See also fabric.
The main memory for the switch.
A group of related frames transmitted in the same direction between two N_Ports.
The rate at which an entity can service requests. See also request rate.
Small form factor pluggable. A type of transceiver used to convert signals between
fiber optic cables and switches.
Sequence initiative.
The brand name for the Brocade family of switches.
The fiber optic cabling standard that corresponds to distances of up to 10 km
between devices.
Simple network management protocol. An internet management protocol that
uses either IP for network-level functions and UDP for transport-level functions,
or TCP/IP for both. Can be made available over other protocols, such as UDP/IP,
because it does not rely on the underlying communication protocols. See also
community (SNMP).
Simple name server. A switch service that stores names, addresses, and attributes
for up to 15 minutes, and provides them as required to other devices in the fabric.
SNS is defined by fibre channel standards and exists at a well-known address.
May also be referred to as directory service. See also FS.
Hardware that routes frames according to fibre channel protocol and is controlled
by software.
The arbitrary name assigned to a switch.
