Chapter 2 Installing and Configuring the Server Switch
Connecting Beyond BladeCenter
Connecting Beyond BladeCenter
To extend your InfiniBand fabric beyond your BladeCenter cluster, you must configure the priority of the subnet manager on your Server Switch Module, then connect one or more of the external interfaces on your Server Switch Module to an outside InfiniBand fabric.
The device with the highest subnet manager priority becomes the master subnet manager in the InfiniBand network. To configure subnet manager priority, follow these steps:
Step 1 Switch to Privileged Exec mode by entering the enable command.
Cisco BladeCenterH> enable
Cisco BladeCenterH#
Step 2 Switch to Global Configuration mode by entering the configure command.
Cisco BladeCenterH# configure
Cisco BladeCenterH(config)#
Step 3 Configure the priority of the subnet manager by entering the ib sm command with this information:
•subnet-prefix keyword
•Subnet prefix of the InfiniBand network to which the Server Switch belongs
•priority keyword
•Priority integer value of the subnet manager (1 is the lowest the priority)
Cisco BladeCenterH(config)# ib sm
Step 4 Exit Global Configuration mode.
Cisco BladeCenterH(config)#exit
Cisco BladeCenterH#
Step 5 Save the configuration by entering the copy
Cisco BladeCenterH# copy
Cisco BladeCenterH#
After you configure your subnet manager priority, connect your Server Switch Module to the outside InfiniBand fabric. By default, the external interfaces on your Server Switch Module
Connecting InfiniBand Cables
To plug in an InfiniBand cable, push the connector into the interface until you hear/feel a click.
To remove a cable with a pull connector, grasp the connector with one hand and push it toward the port, then pull the latch away from the port with your other hand and gently wiggle the connector away from the port.
