Hi Strahil,

Thanks for your reply, I have 16 nodes for now but more on the way.

The reason why Ceph appeals me over Gluster because of the following reasons.

1. I have more experience with Ceph than Gluster.

2. I heard in Managed Block Storage presentation that it leverages storage software to offload storage related tasks.

3. Adding Gluster storage limits to 3 hosts at a time.

4. I read that there is a limit of maximum 12 hosts in Gluster setup. No such limitation if I go via Ceph.

In my initial testing I was able to enable Centos repositories in Node Ng but if I remember correctly, there were some librbd versions present in Node Ng which clashed with the version I was trying to install.

Does Ceph hyperconverge still make sense?

Regards

Shantur

Hi Shantur,

the main question is how many nodes you have.
Ceph integration is still in development/experimental and it should be wise to consider Gluster also. It has a great integration and it's quite easy to work with).

There are users reporting using CEPH with their oVirt , but I can't tell how good it is.
I doubt that oVirt nodes come with CEPH components , so you most probably will need to use a full-blown distro. In general, using extra software on oVirt nodes is quite hard .

With such setup, you will need much more nodes than a Gluster setup due to CEPH's requirements.

Hi all,

I am planning my new oVirt cluster on Apple hosts. These hosts can only have one disk which I plan to partition and use for hyper converged setup. As this is my first oVirt cluster I need help in understanding few bits.

1. Is Hyper converged setup possible with Ceph using cinderlib?
2. Can this hyper converged setup be on oVirt Node Next hosts or only Centos?
3. Can I install cinderlib on oVirt Node Next hosts?
4. Are there any pit falls in such a setup?

Thanks for your help

Regards,
Shantur
