The reason for the zoho (and my) emails go to the spam box is because
the Apache mailing list software is messing around with the DKIM
signature and the "From:" address. I have created INFRA-21415
<https://issues.apache.org/jira/browse/INFRA-21415> for this.

There are operational advantages to having #racks == RF, however it's
by no means mandatory. Having more racks than RF doesn't cause any
availability/health/balance problems, it is only disadvantageous in
that it makes some cluster maintenance tasks more expensive/unwieldy
like repairs and DC migrations. Note that you can re-use racks across
your physical servers assuming you have more physical servers than RF,
it's not necessary to have a separate rack per physical server, as
long as there are at least RF physical servers (ideally these physical
servers should also be in the same rack/AZ in the datacenter to
protect against physical rack/datacenter outage).
FYI this went to spam on GMail. I suspect google is flexing their
monopoly muscles against zoho.

Hi,
In a article by thelastpickle [1], i noticed:
The key here is to configure the cluster so that for a given
datacenter the number of racks is the same as the replication
factor.
When using virtual machines as Cassandra nodes we have to set up
the cluster in a way that number of racks is the same as physical
servers, so by losing one physical server just one copy of any
data would be lost, right? which could be much greater than RF,
would this cause any harm on cluster health/balance/availability?
