Deploying The Cisco Nexus 1100 Series Across Data Centers - Cisco Nexus 1110-S Deployment Manual

As a best practice, back up configurations to a remote site and not on the bootflash drive of the Cisco Nexus
1000V Series VSM. The configuration can be stored on the bootflash drive, but you should have another copy
stored remotely as well.

Deploying the Cisco Nexus 1100 Series Across Data Centers

A multisite data center is commonly used for disaster avoidance and recovery, and although the data centers are in
separate physical locations, they may not be geographically far apart. This sort of deployment helps in
maintenance operations, allowing one site to be brought down for maintenance purposes by shifting network
services across the data center (Figure 21). This approach also helps in load balancing or shifting the network
service to a branch office where it is needed.

Hosting the Cisco Nexus 1000V Series VSM on the Cisco Nexus 1100 Series VSA provides additional benefits
when the VSM spans multiple data centers. Because the Cisco Nexus 1100 Series is managed and operated by
the network administrator, it provides the following benefits compared to deployment of the VSM as a virtual
machine:
●
With a VSM virtual machine deployment, the network administrator needs to engage with the server
administrator to help ensure that the VSM virtual machine has the correct settings and subsequently has no
independent way of tracking where the VSM virtual machine resides. With the Cisco Nexus 1100 Series, the
network administrator determines the exact placement of the VSM and can independently identify exactly
where the active VSM resides at any time.
●
The VMware environment may employ complex VMware vSphere Distributed Resources Scheduler (DRS)
and anti-affinity rules, which the network administrator needs to understand to help ensure correct
deployment of the VSM. The Cisco Nexus 1100 Series provides most operations through the familiar Cisco
NX-OS command-line interface (CLI).
