Synchronous dynamic random access memory. The main memory for
the switch. Used for volatile storage during switch operation. See also
Flash.
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.
A group of related frames transmitted in the same direction between
two N_Ports.
The N_Port that begins a new sequence and transmits frames to
another N_Port.
Serializing/deserializing circuitry. A circuit that converts a serial bit
stream into parallel characters, and vice-versa.
The transmission of data bits in sequential order over a single line.
A computer that processes end-user applications or requests.
The rate at which an entity can service requests. See also Request Rate.
SCSI Enclosure Services. A subset of the SCSI protocol used to
monitor temperature, power, and fan status for enclosed devices.
Small-form-factor. An industry term for a smaller transceiver. See
SFP.
Small-form-factor pluggable. A transceiver used on 2 GB/s switches
that replaces the GBIC.
A cable specifically designed for use with an SFP. Not compatible
with GBICs.
Source identifier/destination identifier. S_ID is a 3-byte field in the
frame header that is used to indicate the address identifier of the
N_Port from which the frame was sent.
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. Also referred to as "directory service" or "name
server."
