Hello All,

I'm looking for hardware configurations to set up 1 master and 2
hot-standby slaves using 9.6 in one DC. Also, I need to have DR with the
same setup with cross-site replication enabled. I went through a lot of
docs/blogs suggesting 4cores and at least 4/8GB RAM. But I'm looking for
help on how exactly one can justify the hardware requirements, like a
formula ? Please advise.

Regards,
PK
