VMware Requirements

This section describes supported VMware products and feature recommendations.

Vocera supports the following products running in a VMware virtualized environment.

Server	VMware Platform
Vocera Server	VMware vSphere 5 with ESXi 5.0 and later
Vocera SIP Telephony Gateway	VMware vSphere 5 with ESXi 5.0 and later
Vocera Rauland Integration SIP Gateway	VMware vSphere 5 with ESXi 5.0 and later
Vocera Client Gateway	VMware vSphere 5 with ESXi 5.0 and later
Vocera Report Server	VMware vSphere 5 with ESXi 5.0 and later

The ESXi hosts in this environment must be managed by a VMware vCenter Server, using a minimum of Standard licensing for both ESXi and vCenter.

Important: Vocera does not support other virtualization platforms, including VMware Workstation, Citrix XenServer, Red Hat KVM and Microsoft Hyper-V.

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)
