You can install multiple VSTG, RSIP and VCG servers, also known as an array, to take advantage
of high availability features. Vocera recommends the following best practices for high
availability:
-
Set up 2 separate VMware ESXi servers for redundancy
-
Install VSTG on each VMware ESXi server
-
For VSTG only: Allocate the total number of SIP lines evenly between the
VSTG servers
Important: (For VSTG only) When you configure the Number of
Lines field on the Telephony > Basic Info
page of the Vocera Administration Console, enter the number of lines available to a
single VSTG server, not the total number of lines available to all
servers. For example, if you purchased a license with 6 lines and you have 2 VSTG
servers, assign 3 lines to each VSTG server.
