SM

The Subnet Manager (SM) configures and manages routers, switches, and channel adapters.

 

Multiple subnet managers per subnet are supported.
SMPSubnet 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

The Target Channel Adapter (TCA) is the complement to HCA. It is the end node component

Adapter

of an I/O device that connects it to the fabric.

TCPTransmission 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

Any protocol residing in OSI Layers five or above. Standard ULPs supported by InfiniBand

Protocol (ULP)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.
