Chapter 4 Configuring the CDS
Array Level Configuration
The thin pipes configured in Table 4-28 ensures that the bandwidth for SHE1 never exceeds the
maximum bandwidth available for SHE1, which is 5 Gbps. This means that even if all remote sites were
requesting cache fills from SHE1, which would be a maximum throughput of 9 Gbps, the actual
maximum bandwidth of cache-fill traffic coming from SHE1 would never exceed 5 Gbps.
One server in the site is elected as the bandwidth manager for all servers in the site. The bandwidth
manager controls the traffic leaving the site to any other site and queries all the CDS servers in the site
for the thin pipe mapping configuration of each CDS server. For more information about the bandwidth
manager, see the “Bandwidth Manager for Thin Pipe” section on page 2-8.
Note Before you can configure thin pipes, you must define the sites. For more information, see the
“Configuring Sites” section on page 4-73.
To configure a Thin Pipe Map, do the following:
Step 1 Choose Configure > Array Level > Thin Pipe Map. The Thin Pipe Map page is displayed.
Step 2 From the Configured Pipes drop-down list, choose Create New Pipe and click Select.
To edit a Pipe Map, choose the Pipe Map from the drop-down list and click Select.
Step 3 From the Local Site drop-down list, choose the site you want to use as the local site for this thin pipe
map.
Step 4 In the Pipe Name field, enter the name for the pipe map.
Step 5 In the Max Transmit Bandwidth field and the Max Receive Bandwidth field, enter the maximum
transmit and receive megabits per second (Mbps) for this pipe.
