Question about cluster and high availability

| If a cluster of two machines (WAS6) (and High availability applied) on the first installed the deployment manger and node1 , on the second machine installed node2?and the first machine went off line the machine two will be still running and serving requst
s?
In other words is this architecture serves a high availability solution or I have to have the network deployment on a separate machine?if the ND is down is the solution will be working?
And if this architecture is fine does it have more limitations than having the deployment manager on separate machine?
Thank you for explaining.

| If you refer to the Red Book sg247387 it recommends that you put the Deployment Manager on a separate node to avoid 'single point of failure'.
Installing Deployment Manager on Node 1 or Node 2 will result in you still being able to use Node 2 but only. You may need to remove it from the cluster to do so.

Yes. If the dMgr is down your application will continue to work, you are
just unable to deploy changes to it.

It's generally regarded as better to have the dMgr on a separate box or
LPAR as it makes recovery simpler.
