We are looking at moving our WebSphere workload from z/OS to Linux. We have 
lots of 4way x86 Linux boxes running WebSphere - each instance capable of 
running dozens (nearly 100 in some cases) of application servers (JVMs) with 
many GB of memory.  On WebSphere for z/OS, an LPAR might have 32 application 
servers collectively collectively using 8GB of memory and 2 zAAPs - not saying 
that is the max it can run, it's just a sample size of an existing workload.

If I move this example Websphere for z/OS workload to zLinux, would it fit on 
one Linux guest with 8GB of virtual memory and 2 IFL's.

Anyone have rules of thumb to offer regarding trying to run a single virtual 
zLinux for WebSphere with something like 8GB memory and dozens of application 
servers? This WebSphere design works great for us on x86 and z/OS, so wondering 
if it holds true on zLinux.

Thanks,
