currently we are running ECC on HP-UX (hardware HP DL 380). The machine has 24 GB of RAM and 4 dual core CPUs. It gives us the performance we need. Soon we plan to move to a Solaris OS on SUN T5440. My question is - would we require same 24 GB of RAM and same 8 core power on this ? Or would it be more or less ? any kind of comparison matrix ?
Please dont tell me to run a quicksizer and look at benchmarks etc etc, I dont have time and I just need a ball park comparison for now. Your inputs from your experiences would help. thanks
