Agent (HS-Series Agent) Command Console’s secure TCP/IP network communication
program. Agent runs on your subsystems' host computer. It is
available on several operating systems. One or more Client
programs can access the HS-Series Agent running on a host
system. Using the system's SCSI or Fibre Channel bus, the
Agent can communicate with multiple subsystems on the same
host system. You can configure the HS-Series Agent with

communicate with storage connected to the HSxxx controller.

to both controllers in a dual-redundant configuration.
