Ceph cluster production

As mentioned throughout this book, Ceph is a very resilient distributed storage system that pairs well with Proxmox to store virtual disk images. There are a few key factors that make a Ceph cluster a good choice for a production-level virtual environment.

Forget about hardware RAID

When it comes to Ceph nodes and clusters, we can forget about hardware-based RAID. Instead, we have to think multi-node or clustered RAID. That is because of the distributed nature of Ceph and how data is dispersed in all the drives in the cluster regardless of which node the drive is in. With Ceph, we no longer need to worry about a device failure in a particular node. Ceph performs best when it is given access to each...
