Hardware System Requirements for Extra Large Deployment of Aternity on-premise (up to 150,000 devices)

The extra large Aternity deployment supports up to 150,000 monitored devices or virtual desktops, where up to 10% of them (15,000) are virtual application sessions from up to 900 virtual application servers. It supports 10 concurrent Aternity users, and assumes up to 10 monitored managed application per device which monitor the application's resource usage.

Sizing for a Extra Large Deployment

Contact Customer Services to help you estimate the size of your deployment, by calculating the following values:

Deployment Max # devices and VDIs # virtual sessions # virtual servers PRC WPM AR/min Non-WPM AR/min Discovery AR/min Aternity users

Extra Large Aternity deployment (see hardware requirements)










  • # devices and VDIs is the maximum number of monitored physical devices and virtual desktop VDIs (not their hypervisors) which report their performance to Aternity at the same time.

  • # virtual sessions is the maximum number of monitored virtual application sessions reporting their performance to Aternity at the same time.

    # virtual servers is the maximum number of virtual application servers (like Citrix XenApp) or RDP servers, which generate the monitored virtual sessions.

  • PRC is the average number of PRC monitors per device, averaged over 24 hours. By default, devices report PRC once an hour.

  • AR/min is the maximum number of activity response times reported per device per minute at peak times. There are two types:

  • Discovery AR/min The average number of applications which are actively in use simultaneously on a device per minute, which report discovery data (like usage time, wait time and UXI).

  • Aternity users The number of simultaneous users accessing the dashboards and administration features of Aternity.
