Update Manager
318 Management Edition
One of the Management components, the Update
Manager runs on the Management Server and provides
one of three methods for updating member machines. It
can retry updates to machines that are powered off. You
can configure the number of retries and specify the
maximum number of machines to simultaneously
update, using traffic limitation. This limits traffic to and
from the Management Server, preventing it from
running out of connections or from flooding it with
file-copy requests when updating many machines.
