Hardware Requirements

Parallels RAS is extensively tested on both physical and virtual platforms. The minimum hardware requirements approved to run Parallels RAS are outlined below.

• Physical Machines – Dual Core Processor and a minimum of 4GB RAM.
• Virtual Machines – Two Virtual Processors and a minimum of 4GB of RAM.

The server hardware requirements to install and configure Parallels RAS can vary according to end-user requirements.

Typically for an installation of 30 users or under, Parallels RAS can be installed on one high specification server and the resources published directly from it. For more than 30 users, multiple servers may be required.

The below should be considered during the planning stage of a Parallels RAS deployment:

• High specification servers should be used, consisting of multiple CPU cores, a high specification disk transfer rate and plenty of RAM.
• A hypervisor-based virtual machine can be used as long as the resources needed to serve end-users are calculated accordingly.
• It is recommended that RD Session Hosts do not exceed 50 users per RD Session Host in usage.
• It is recommended that RAS Secure Client Gateway does not exceed 1000 users per server for incoming connections using the Gateway SSL mode.
• When planning VDI Hypervisor resource requirements, extra requirements such as RAM usage per virtual machine and disk space should be taken into account.
