Re: [ceph-users] Network performance
Hi Jonas, you can create an bond over multible NICs (depends on your switch which modes are possible) to use one IP addresses but more than one NIC.

Yes, but if an OSD would listen to all IP adresses on the server and use all nics we could have more performace and high availability without bonding. ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

[ceph-users] Network performance
Hello, In the configuration I have read about "cluster network" and "cluster addr". Is it possible to make the OSDs to listens to multiple IP addresses? I want to use several network interfaces to increase performance. I hav tried [global] cluster network = 172.16.3.0/24,172.16.4.0/24 [osd.0] public addr = 0.0.0.0 #public addr = 172.16.3.1 #public addr = 172.16.4.1 But I cant get them to listen to both 172.16.3.1 and 172.16.4.1 at the same time. Any ideas? /Jonas ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

But I cant get them to listen to both 172.16.3.1 and 172.16.4.1 at the
same
time.
Any ideas?
I don't think this is currently possible, but it would be nice if Ceph
supported something like
http://www.multipath-tcp.org/
In the documentation I can read how to add multiple networks. Why is that
possible if it cant be used? :-)
cluster network
Description: The IP address and netmask of the cluster (back-side)
network (e.g., 10.0.0.0/24). Set in [global]. You may specify comma-delimited subnets.
Type: {ip-address}/{netmask} [, {ip-address}/{netmask}]
Required: No
Default:N/A
