If your Vocera system has multiple sites, you can install a Vocera Client Server (VCG) at each site, or install multiple VCGs at each site for redundancy.
As long as you have multiple VCGs deployed, you can take advantage of high availability features.
The following multiple site scenario shows only one VCG installed at each site. This scenario lacks VCG redundancy unless smartphones are configured to connect to the VCGs at both sites.
Note:
Vocera Voice Server version 4.4.3 and later
support site-aware VCGs.

| Summary | |
|---|---|
| Sites: | Multiple |
| High Availability: | No, unless smartphones are configured to connect to both VCGs across the WAN |
The following multiple site scenario represents the best practice for high availability support. It has arrays of VCG servers installed at each site.
