VMware Feature Recommendations

Vocera recommends that you do not use VMware vMotion, DRS, Storage vMotion, or Storage DRS features on certain Vocera Servers (VS, VCG, VSTG, or RSIP). These feature have the potential to disrupt real-time communication. VM Override rules or Affinity/Anti-Affinity rules should be used if possible, or selectively disabling some of these features, to prevent these actions. Performing vMotion on a running Vocera server is likely to cause some or all of the following:
  • Cluster failover (all active badge calls will be dropped)
  • Badges displaying the Searching For Server error and not able to make calls
  • Gateway disconnects (all active gateway calls will be dropped)
  • Interruption in communication (badge-to-server communication such as speech recognition and call setup)
