The Sophos Community will be unavailable from 13:00 to 18:00 UTC this Saturday, October 1st for upgrades. Stay tuned to our Twitter account @SophosSupport for updates.
Sophos Update Manager (SUM) is always installed on the computer where the Enterprise Console is installed. This is the component which is responsible for getting the updates from Sophos and is the updating source for the computers on your network. In some circumstances there may be a requirement to install an additional SUM to alleviate slow network connections / bandwidth due to all clients trying to update from the same update source at the same time.
This article explains how to add one or more additional SUM's to the network. This is to reduce the load on the existing SUM that is already installed on the Enterprise Console and distribute updates more efficiently to the remote computers.
Apply to the following Sophos product(s) and version(s) Sophos Update Manager
Further information can be found on section 7.6 of the Sophos Enterprise Console Advanced Startup Guide
