Information in this document applies to any platform.
This note to clarify the users followed the MOS <Note 1917553.1> and but a concern raised on, "The number of coherence nodes per site must be the same, otherwise it is not possible to achieve SITE-SAFE status, as only RACK-SAFE or MACHINE-SAFE is possible." Assume a case, N machines in one data center and N-1 in the other one. There is more than enough memory in the smaller data center, why is there such a requirement that recommends maintain a homogeneous strength across the data centers?
