HP Fabric Clustering System HP-UX Administrator's Guide, March 2008

SM The Subnet Manager (SM) configures and manages routers, switches, and channel adapters.
Multiple subnet managers per subnet are supported.
SMP Subnet Management Packet (SMP) on the fabric.
SNMP Simple Network Management Protocol (SMNP) lets a user define management information
base (MIB) extensions. SNMP agents access MIB objects when requested by an SNMP Manager.
Target Channel
Adapter
The Target Channel Adapter (TCA) is the complement to HCA. It is the end node component
of an I/O device that connects it to the fabric.
TCA See Target Channel Adapter (TCA).
TCP Transmission Control Protocol (TCP).
TFTP Trivial File Transfer Protocol (TFTP) is a simplified version of FTP that allows files to be
transferred from one computer to another over a network, usually without the use of client
authentication (for example, username and password).
Traps Unsolicted reports sent by SNMP agents to interested clients. Trap messages are used to report
significant TCP/IP events asynchronously.
UDP An Internet protocol that provides connectionless datagram delivery service to applications.
UDP over IP adds the ability to address multiple endpoints to IP within a single network node.
Unicast Analogous to PPP, unicast is a communication link between a one sender and one receiver.
Unlike multicast, unicast is the serial transmission of data between a sender and receiver.
Upper Layer
Protocol (ULP)
Any protocol residing in OSI Layers five or above. Standard ULPs supported by InfiniBand
include Internet Protocol (IPoIB) and Message Passing Interface (MPI).
VLAN Virtual LAN. Unlike conventional LANs, a VLAN uses methods other than geographic location
to map workstations. This allows the administrator to more easily manage load-balancing,
band-width allocation, and add new users.
