Which option is good for SHA-2 in CA?

-

hi guys,

i have project provide many service public users on web. in project have many server sql server, ntp server, ca server, many dc, iis server, dns server, file server, mail server , etc.

i want supply security structure in internal communications, relation of between iis , sql, or firewall , dc , other anythings.

i think, should have ca structure 3 tier (root ca, policy ca, issuer ca). in opinion, should have policy ca, can extend ca structure in future.

for implement above structure, have big problem selection of sha config in root ca, policy ca , issuer ca. want use sha-2 project. don't know option project.

224 or 256 or 384 or 512 or 512/224 or 512/256?

note: know microsoft ca don't support sha-3 @ now, (that bad, because sha-1 , sha-2 have similar structure).
