Summary
Performance of the 12-port AB291A is equivalent or better than that of a single TS170 12-port line
card. This is expected, since a CLOS switch requires more switch hops than the non-CLOS AB291A
architecture.
18-node cluster
TS170 configuration
The following configuration is used to construct an18-node cluster with balanced utilization of the 12-
port line cards of the TS170. As in the previous TS170 configuration, an AB291A 12-port switch is
used as an SM for the fabric:
