With a VSM virtual machine deployment, the network administrator can lack control over disaster avoidance
and recovery operations. The VMware vSphere DRS rules apply for all hosts regardless of whether they are
hosting a virtual machine or specific network services. The Cisco Nexus 1100 Series VSA helps the network
administrator concurrently perform disaster avoidance and recovery operations for the specific network
services that it hosts.
The configuration and setup processes for the Cisco Nexus 1100 Series across data centers are no different from
those for the deployment in a single data center. To help ensure high availability, the Cisco Nexus 1100 Series pair
must be Layer 2 adjacent, similar to the Cisco Nexus 1000V Series VSM, and it must have a round-trip latency of
less than 10 milliseconds (ms).
Appendix: Quick Configuration Guide
This appendix provides a quick configuration guide for instantiating a VSM on a Cisco Nexus 1100 Series VSA.
The example uses network connectivity option 3 and shows how to bring up a VSM in Layer 3 mode, register the
VSM with VMware vCenter, and add a VMware ESX or ESXi server as a VEM (Figure 22). The steps for
registering the VSM with VMware vCenter and adding a VEM are standard in configuring the Cisco Nexus 1000V
Series and are independent of the platform for which the VSM is installed (either a virtual machine or the Cisco
Nexus 1100 Series).
