RAM Requirements for Vocera Voice Server

The following table lists the Vocera Voice Server hardware (RAM) requirements for small, medium, and large Vocera Analytics servers.

Requirement	Extra Small	Small	Medium	Large
RAM Additions for Voice Server	1 GB	2 GB	2 GB	4 GB

Note: For Voice Servers in cluster mode, ensure additional RAMs are added on all nodes.

Note: Vocera Analytics does not support memory oversubscription.

Note: Each Vocera Analytics server configuration supports 1 Active Directory at a time.

Note: Each Vocera Analytics server configuration supports 1 Vocera Voice Server.

Note: To run properly, the Vocera Analytics Agent running on a Vocera Voice Server (VS) will require 2 GB of RAM when interacting with a small or medium Vocera Analytics Server database and 4 GB of RAM when interacting with a large Vocera Analytics Server database. If the VS does not have sufficient memory to meet the mandated minimum memory for the VS plus the needs of the Vocera Analytics Agent, memory will need to be added to the VS. For example, a VS running version 5.2.3 requires a minimum of 8 GB of RAM. If the Vocera Analytics Agent will be interacting with a large Vocera Analytics Server database requiring 4 GB of RAM, the server running the VS and the Vocera Analytics Agent must have a minimum of 8 + 4 or 12 GB of RAM installed. If it does not, sufficient RAM to meet or exceed the 12 GB requirement should be added. If the VS is running in a virtual environment, Memory Over Subscription is not supported and the Host Server should have sufficient physical RAM to support the memory allocated to the Guest Servers plus the Hypervisor.

Disk Space Requirements for Vocera Voice Server

As Vocera Analytics recommends you to retain Voice Server log files for 7 days, ensure that you increase the disk space accordingly. For example, within a day, if 5 GB Voice Server logs are generated, then you must have at least an additional 35 GB disk space.

Note: Ensure that you add the additional disk space on all nodes of the Voice Server.
