How many clients can I connect to my server?
Experience has shown us that it is recommended to allow 5 times the
number of connected sessions for any given operating system to calculate
a practical number of clients that will connect to a given server. However,
it’s possible that even if using the recommended maximum number of users
per Mirror, there will be situations when some clients might get an error
message during update. The only way to totally guarantee no connection
errors, is to set the ratio to 1:1 (operating system allowed connections :
number of clients) but we have found 1:5 is an acceptable ratio.
Client computers probably do not have their scheduled updates completely
synchronized. Automatic update occurs an hour after the last update,
so even if all clients were installed exactly at let’s say 8:00 then the first
automatic update will be scheduled for all of them at 9:00. But in the
meantime one client could hit the ‘Update Now’ button or has restarted
(and thus update occurred during logon) let’s say at 8:30. Even if there
was actually no fresh update available at that time, the next regular update
check for this client will move to 9:30 while the rest of the clients will
check it at 9:00. So as time passes and clients shut down or restart their
computers, the time interval of update spreads to the point where there is
not big risk of downloading the update with too many clients simultaneously.
Also there is the possibility to improve this further by ticking Disconnect
from server after update has completed in Advanced Mirror Setup.
By ticking this option, the update of more clients from one Mirror can be
achieved.
