Connectrix B Series XPath OS AP-7420B Hardware Reference Manual
The overall design of a storage network solution, which includes one
or more related fabrics, each of which has a topology.
The number of ports available for connection by nodes in the entire
SAN.
One of the properties of a SAN: the size to which a SAN topology can
grow port and switch counts with ease.
SCN State change notification. Used for internal state change notifications,
not external changes. This is the switch logging that the port is online
or is an Fx_port, not what is sent from the switch to the Nx_Ports.
SCR State change registration. Extended Link Service (ELS) requests the
fabric controller to add the N_Port or NL_Port to the list of N_Ports
and NL_Ports registered to receive the Registered State Change
Notification (RSCN) Extended Link Service.
SCSI Small computer systems interface. A parallel bus architecture and
protocol for transmitting large data blocks to a distance of 15-25
meters.
SCSI-2 An updated version of the SCSI bus architecture.
SCSI-3 An SCSI standard that defines transmission of SCSI protocol data
over different kinds of links.
SDRAM Synchronous dynamic random access memory. The main memory for
the switch. Used for volatile storage during switch operation. See also
Flash.
A protocol similar to Telnet but with encrypted passwords for
increased security.
A feature that provides advanced, centralized security for a fabric.
A set of rules that determine how security is implemented in a fabric.
Security policies can be customized through Secure Fabric OS or
Fabric Manager.
SEQ_ID Sequence identifier. A 1-byte field in the frame header change to
identify the frames as being part of a particular exchange sequence
between a pair of ports.
