We intend build a new Ceph cluster with 6 Ceph OSD hosts, 10 SAS disks
every host, using 10Gbps NIC for client network, object is replicated 3.

So, how could I sizing the cluster network for best performance?
As i have read, 3x replicate means 3x bandwidth client network = 30 Gbps,
is it true? I think it is too much and make great cost

Do you give me a suggestion?

Thanks in advance.
