Minimum requirements for application servers

Web CRS

A typical installation consists of CRS being installed on a Web server (Web CRS). In this instance, processing is done on the server. The
number of planned concurrent coders should be multiplied by 1.5 for sizing and configuration purposes, up to a maximum of 675 on a
single server. Using this configuration, you must provide:
• Memory—A minimum of 4GB of RAM for the operating system, plus 1GB for every 40 concurrent users
• CPU Cores—A minimum of two CPU cores with a base clock of 2+ GHz each, plus one additional core for every 40 concurrent
users
• Disk space—20GB for coding system install

Windows CRS (USA only)

Customers in the United States also have the option to install CRS without a Web server (Windows CRS). In this configuration,
processing is done on the client machine, so there are no additional memory or CPU requirements for the server. The maximum number
of clients per application server is 35.
• Disk space—20GB for coding system install
