soft zone A zone consisting of zone members that are made visible to each other through
client service requests. Typically, soft zones contain zone members that are
visible to devices using Name Server exposure of zone members. The fabric
does not enforce a soft zone. Note that well-known addresses are implicitly
included in every zone.
SoIP Storage over IP or SoIP is a technology for accessing 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 networks that provides
building blocks and flexible payload mappings.
special character A 10-bit character that does not have a corresponding 8-bit value but is still
considered valid. The special character is used to indicate that a particular
transmission word is an ordered set. This is the only type 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 pair.
Storage resource management. The management of disk volumes and file
SRM
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 between web servers and web clients.
Standard A method that allows public devices to communicate with private devices that
Translative Mode are directly connected to the fabric.
stealth mode A method used in some switches to simulate HP switches using QuickLoop.
Stitch The code name given to the first-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 frame before making a
routing decision.
striping A RAID technique for writing a file to multiple disks on a block-by-block basis,
with or without parity.
switch A fabric device providing bandwidth and high-speed routing of data via
link-level addressing.
switch name The arbitrary name assigned to a switch.
switch port An access point on a switch where a link attaches. Switch ports can be E_Ports,
F_Ports, or FL_Ports.
switch-to-switch The process of authenticating both switches in a switch-to-switch connection
authentication using digital certificates.
See also authentication and digital certificate.
