Fabric OS 5.0 features overview 33
NS Name Server. The service provided by a fabric switch that stores names, addresses,
and attributes related to Fibre Channel objects. Can cache information for up to 15
minutes. Also known as Simple Name Server or as a directory service. See also
Simple Name Server.
out-of-band Transmission of management protocol outside of the Fibre Channel network, usually
over Ethernet.
oversubscription A situation in which more nodes could potentially contend for a resource than the
resource could simultaneously support (typically an ISL). Oversubscription could be
a desirable attribute in fabric topology, as long as it does not produce
unacceptable levels of congestion.
Performance
Monitoring
An HP StorageWorks switch feature that monitors port traffic and includes frame
counters, SCSI read monitors, SCSI write monitors, and other types of monitors.
PKI Public key infrastructure. An infrastructure that is based on public key cryptography
and CA (certificate authority) and that uses digital certificates.
PKI certification
utility
Public key infrastructure certification utility. A utility that makes it possible to collect
certificate requests from switches and to load certificates to switches. See also
digital certificate, PKI.
port In an HP StorageWorks switch environment, an SFP or GBIC receptacle on a
switch to which an optic cable for another device is attached.
port address In Fibre Channel technology, the port address is defined in hexadecimal. In the
Fabric OS, a port address can be defined by a domain and port number
combination or by area number. In an ESCON Director, an address used to specify
port connectivity parameters and to assign link addresses for attached channels
and control units.
port card A hardware component that provides a platform for field-replaceable, hot
swappable ports.
port log A record of all activity on a switch, kept in volatile memory.
port name A user-defined alphanumeric name for a port.
port_name The unique identifier assigned to a Fibre Channel port. Communicated during login
and port discovery.
port swapping Port swapping is the ability to redirect a failed port to another port. This feature is
available in Fabric OS 4.1.0 and higher.
POST Power-on self-test. A series of tests run by a switch after it is turned on.
PPP Point-to-Point Protocol.
