<div><p>When changes are made to a cluster, the overhead necessary to manage
|
||
|
|
the cluster can be affected.</p>
|
||
|
|
<p>The only resources that clustering requires are those necessary to perform
|
||
|
|
heartbeat monitoring, to manage the cluster resource groups and the cluster
|
||
|
|
nodes, and to handle any messaging taking place between cluster resource groups
|
||
|
|
and cluster nodes. Once your clustering environment is operational, the only
|
||
|
|
increase in overhead will be if you make changes to the cluster.</p>
|
||
|
|
<p>During a normal operating environment, there should be minimal impact to
|
||
|
|
your clustered systems due to clustering activity.</p>
