Q

E – Glossary

SDP

For Sockets Direct Protocol. An InfiniBand-specific

 

upper layer protocol. It defines a standard wire protocol

 

to support stream sockets networking over InfiniBand.

SRP

For SCSI RDMA Protocol. The implementation of this

 

protocol is under development for utilizing block

 

storage devices over an InfiniBand fabric.

SM

For Subnet Manager. A subnet contains a master

 

Subnet Manager which is responsible for network

 

initialization (topology discovery), configuration, and

 

maintenance. The Subnet Manager discovers and

 

configures all the reachable nodes in the InfiniBand

 

fabric. It discovers them at switch startup, and

 

continues monitoring changes in the physical network

 

connectivity and topology. It is responsible for assigning

 

local identifiers, called LIDs, to the visible nodes. It also

 

handles multicast group setup. When the network

 

contains multiple managed switches, they negotiate

 

among themselves which will be the controlling Subnet

 

Manager. It communicates with the SMAs that exist on

 

all nodes in a cluster.

SMA

For Subnet Management Agent. SMAs exist on all

 

nodes, and are responsible for interacting with the

 

subnet manager to configure an individual node and

 

report node parameters and statistics.

subnet

A single InfiniBand network.

switch

Used to connect HCAs and TCAs. Packets are

 

forwarded from one port to another within the switch,

 

based on the LID of the packet. The fabric is the

 

connected group of switches.

TCA

For Target Channel Adapter. A TCA is a channel

 

adapter for I/O nodes, such as shared storage devices.

TCP

For Transmission Control Protocol. One of the core

 

protocols of the Internet protocol suite. A transport

 

mechanism that ensures that data arrives complete and

 

in order.

TID

For Token ID. A method of identifying a memory region.

 

Part of the InfiniPath hardware.

uDAPL

For user Direct Access Provider Library. uDAPL is the

 

user space implementation of the DAPL protocol.

unmanaged switch

A switch that does not have an active Subnet Manager

 

(SM).
