Every device has an associated device pool. That device pool has a CM
Group. If the server A is in that CM group, then when ccm.exe starts
on server A it retrieves all device configuration from the SQL database
and caches it in memory. More devices that can potentially register to
this server = more memory for ccm.exe. This applies to primary and
secondary CM's in the CMGroup. Tertiary server does not cache by
default. However, if server ever sees a register request from a device
it will fetch config from database and then subsequently maintain that
config in memory until ccm.exe is restarted.<br>

Just wondering if there are any known issues with running on 1GB, if I
decide to upgrade the RAM should we really see any benefit? Just
wondering what is the most affected on CallManagers with regards to
RAM?
