4.4.3. Chelsio Entity Settings
Description
Chelsio Entity Parameters pass control information to the Chelsio iSCSI module. The
parameters are specific to Chelsio’simplementation of the iSCSI node (target or initiator) and
are unique for each entity block. The parameters consist of information that can be put into
three categories:
1. Challenge Handshake Authentication Protocol (CHAP).
2. Target specific settings. All of the following parameters can have multiple instances in one
target entity block (i.e., they can be declared multiple times for one particular target).
