I will be starting with production setup including one Admin server and 4 managed servers in one single domain.
I am thinking of creating a single node environment(no clusters) as the machine has following configuration
OS : Windows Server 2008 R2 Datacenter
RAM : 48 GB
System Type : 64 bit
Processor : Intel(Xenon) 4 processors X5627@3.6GHz
Can you please let me know if this configuration would suffice for the 4 managed servers if i assign Xmx and Xms as 4096 and Heap Space as 1024 to all the Managed Servers.
It is very urgent and i need to convey to the Infrastructure team if harware procurement is required.
We are looking at somewhere around 300 concurrent users(maximum load) and 100(minimum load) at a given point of time.
Please reply ASAP.
Thanks in advance

Heap size must be calculated according to the applications that are been deployed on each JVM.
With no deployments, you dont need more than 256k for managed servers heap size and 512k for adminserver. As biggest its your heap size, longer will take your garbage collection. And if you can prevent it, better do it.
