RSS: Different # CPUs?

IDS 12.10.FC12 Oracle T4-1 Solaris 10 1/13 We are contemplating new hardware purchase. Specifically, several Oracle/Fujitsu M12-1's. Initial purchase would be with 3 cores activated (out of 6 available on machine) for our production server. Wondering about using one of them for RSS, but with only one or two cores activated. Will an RSS work, if configured with fewer CPUs than the primary? Thank you. DG

RSS need less CPU then primary unless you are using extensively for read operations like running complex reports. You can run using single core but more resources may be required if promote it to primary(RSS is an HA node)

Those were my thought exactly. But, was uncertain whether RSS required identical settings in ONCONFIG as the primary. Thank you. DG
