soft zone A zo n e consisting of zone members that are made visible to each other through
client service requests. Typically, soft zones contain zone members that are
visibletodevicesusingNameServerexposureofzonemembers. Thefabric
does not enforce a soft zone. Note that well-known addresses are implicitly
included in every zone.
SoIP Storage over IP or SoI P is a technology for acc essing storage devices over
TCP/IP networks. Storage becomes accessible to users directly across the
network, and much of the overhead imposed by server and operating system
intervention is removed to improve performance.
SONET Synchronous optical network. A standard for optical n et works that provides
building blocks and flexible payload mappings.
special charac ter A10-bitcharacterthatdoesnothaveacorresponding8-bitvaluebutisstill
considered valid. The special character is used to indicate tha t a particular
transmission word is an ordered set. This is the only t ype of character that has
five ones or zeroes in a row.
SPLD Simple PLD. Usually, either a PLA or PAL.
SPOF Single point of failure. Any component in a SAN whose malfunction could
bring down the entire SAN.
SQ_ID Sequence ID. An identifier used to select and track all of the frames within a
sequence between a source (S_ID) and destination (D_ID) port p air.
SRM Storage resource managem ent. The managem ent of disk volumes and file
resources.
SSH Secure shell. Starting in Fabric OS 4.1, software used to support encrypted
telnet sessions to the switch. SSH encrypts all messages, including the client
sending the password at login.
SSL Secure sockets layer. A web protocol for establishing authenticated and
encrypted sessions bet ween web servers and web clients.
Standard
Translative Mode
A m ethod that allows public devices to communicate with private devices that
are directly connected to the fabric.
stealth mod e A method used in some switches to simulate HP switches using QuickLoop.
Stitch Thecodenamegiventothefirst-generation Fabric ASIC. This is the ASIC that is
used in the Fibre Channel Storage Switch 8 and Fibre Channel Storage Switch
16 switches.
storage A device used to store data, such as a disk or tape.
store-and-forward A switching technique that requires buffering an entire fram e before making a
routing decision.
striping A RAI D technique for writing a file to multiple disks on a block-by-block basis,
with or without parity .
s
witch
A
fabric device providing b andwidth and high-speed routing of data via
link-level addressing.
switch name The arbitrary name assigned to a swi tch.
switch port An access point on a switch where a link attaches. Switch ports ca n be E_Ports,
F_Por ts, or FL_Ports.
switch-to-switc

The process of aut
henticating both switches in a switch-to-switch connection
using digital ce
rtificates.
