Base HA - 7017 Cluster Server System Cabling
This section provides cabling information for the base HA - 7017 Cluster Server. The
two 17S/80s should be installed and operational before cabling the HA - 7017 Cluster
Server. There are four areas of cabling that you need to consider to ensure the
redundancy required for no single points of failure:
v
Cabling for server system consoles and cluster administration workstations
v
Heartbeat connections between HA - 7017 Cluster Servers
v
SSA cable connections between HA - 7017 Cluster Servers and 7133 Serial Disk
Subsystems
v
Power cable connections.
Cabling For System Consoles and Cluster Administration Workstations
The system console for an HA - 7017 Cluster Server can be either an ASCII terminal
connection to the S1 serial port or a graphics terminal connected to a graphics display
adapter with keyboard and mouse connections directly to the keyboard and mouse
ports on the server.
A cluster administration workstation is connected through a LAN connection.
This section shows the cabling requirements for these connections.
