Interaction Media Server Requirements

Note: If you are installing a packaged server from Genesys, also known as an Interaction Media Server appliance, do the procedures in the Interaction Media Server Appliance Installation and Configuration Guide.

Interaction Media Server hardware and network minimum requirements


Ensure that your Interaction Media Servers meet the minimum hardware requirements. Otherwise, you can experience service outages and Genesys Customer Care won't provide technical support until you meet the minimum hardware requirements.

CPU (minimum)

Intel quad-core, hyper-threaded CPU


4 GB

Local storage space

2 - 500 GB SATA hard drives


256 MB Battery Backed Write Cache (BBWC)

Power supply units (PSUs)

2 - 365 W redundant power supply units

Network interface

1 GB Ethernet with driver software that supports Receive Side Scaling (RSS)


Receive Side Scaling (RSS) is a technology that distributes the processing of received network packets across multiple physical CPU cores. For RSS to function, the operating system, the network interface card (NIC) hardware, and the NIC driver must support this feature. RSS is, however, independent of any application, such as Interaction Media Server.

You can use the Device Manager application in Windows to ensure proper RSS configuration of the NIC. Set the number of queues that the RSS feature of the NIC supports to a number that is equal to the number of physical CPU cores in the host computer. The RSS settings for NICs vary between the different brands and models of NICs. Consult the documentation for the NIC to configure the RSS queue to the appropriate value.

Domain (optional)

If you do not connect Interaction Media Server to a domain, limit the computer name of Interaction Media Server to a maximum of 15 characters. Failure to follow this restriction can result in connectivity problems.

For assistance with determining hardware requirements for various workloads, see the following:

Interaction Media Server software requirements

  • Datacenter edition

  • Enterprise edition

  • Standard edition


Microsoft .NET Framework 4.7 or later and Microsoft .NET Framework 3.5.1 or later


To enable Microsoft .NET Framework 3.5.1 or later, use Server Manager -> Features.
