Does any one know how to calculate hash rate for zcash?

What i mean by that exactly is:

What specification i need to consider from CPU and GPU and other factors to calculate h/s?

Also what is calculation formula to do the calculation?

I was looking a lot and i can't find anything solid.

For example let say i would like to calculate hash power of that HPC: http://www.avadirect.com/Intel-LADMP2312KXXX44-Xeon-Phi-Processor-7210-SATA-Series-Server-System/Configure/10818352?sgd=333d333d318d313d319d308&gclid=CMzf78jYktACFcsmhgodNEQAIA

How to do it? Step by step, please?
