We have about 25 WAS servers running PEGA on zLinux. We created two zVM LPARS and clustered WAS across the two; this has worked really well allowing us to do maintenance on individual servers or zVM LPARS with no service interruptions. The biggest frustration we have had is reconciling zLinux memory and java heap sizes, the Heap Sizes seem to prefer to think in "intel" memory.

Our site is looking to upgrade from WebSphere 7 Base to 8.5 ND. The new Network Deployment version provides clustering and easier(?) maintenance. However I was wondering about the true advantages of WAS ND running under Linux on a single mainframe. For sure, we would be trading simplicity for a more complex environment, and am wondering about the advantages versus disadvantages that others have experienced. We have one application with one production WAS server, and several test WAS environments each running on their own Linux instance.
