Red Hat Ceph Storage Review

Data redundancy means no data or service loss during disk/server failure

What is our primary use case?

We used Ceph as back-end storage for our internal cloud, based on OpenStack.

Our environment was a small open-source OpenStack cloud, on 10 Dell servers, each with two 1TB disks. We installed Ceph on each server to handle those disks and integrated OpenStack Cinder with Ceph to be used as cloud storage instances.

How has it helped my organization?

Scale out storage and storage redundancy.

What is most valuable?

Data redundancy, since it can survive failures (disks/servers). We didn’t lose our data or have a service interruption during server/disk failures.

What needs improvement?

Rebalancing and recovery are a bit slow.

For how long have I used the solution?

One to three years.

What do I think about the stability of the solution?

I used it for about two years. We had no service interruption and no loss of data.

Which other solutions did I evaluate?

I have used (or know) the following distributed/shared file systems: Gluster, NFS, GFS2, and Ceph. For me, Ceph is one of the best.

Disclosure: I am a real user, and this review is based on my own experience and opinions.

Yes, agree. What about capacity utilization? Can Ceph data redundancy easily achieve 80% usable?
