4. If you don't mind, can you please give me a bit of insight on cluster
network, what it is and how i can configure one for my ceph cluster ?
Will there be a significant performance improvement with this ?
When a client submits a write to Ceph, it needs to be replicated
(usually to two replicas). If all the ceph servers have two network
interfaces, and you have two separate networks you connect the servers
to, you can make the replication traffic go over the second interface,
and thus you'll have more available bandwidth between the cluster and
the clients in the first one.
That sounds really interesting, any pointers on how that can be configured?
You should take a look at:
* public_addr
* cluster_addr
* public_network
* cluster_network
(From: src/common/config_opts.h)
[osd]
cluster network = 192.168.0.0/16
public network = 172.16.0.0/16
[osd.1]
cluster addr = 192.168.0.1
public addr = 172.16.0.1
I haven't played with those options, but that should do it (I think)
Wido
As far as I can see, this is going to me I will have to assign to IP addresses
to each node, one for internal traffic, one for external...
Regards,
Guido
