Testing Cisco's Media-Centric Data Center

June 11, 2009 |

  • Key finding: The Nexus 7000 kept running a full traffic profile, with zero packets lost, when a linecard with an active control plane was physically removed from the switch.

    In the previously released IP Video Service Delivery Network report we detailed a series of control plane failover tests performed on Cisco's CRS-1 and ASR 9010 routers. In addition to these core and aggregation routers, Cisco asked that we run this test on the Nexus 7000 in the data center.

    To do this, we repeated the same procedure used when testing the CRS-1 and ASR 9010 as described in the previous article, consisting of running the full traffic profile under steady network conditions and physically removing the card with the active control plane.

    Throughout three full repetitions of the test we observed zero packets lost, indicating that a control plane failure in the Nexus 7000 would not induce a negative impact on the end user. That’s another useful piece of news for the service provider operating a data center. All he needs are two control planes in each Nexus 7000 switch for both control plane failure conditions and hitless software upgrade – and for that he gets many more good night sleeps.
