Hello everybody, I'm looking at Ceph as an alternative for my current storage solution, but I'm wondering if it is the right choice for me. I'm hoping you guys can help me decide. The current setup is a FreeBSD 10.1 machine running entirely on ZFS. The function of the machine is offsite backup for important data. For some (fairly rapidly changing) data this server is the only backup of it. But because the data is changing fairly quickly (every day at least) I'm looking to get this server more HA then it is now.
I think that last sentence is the key bit -- you're looking for an HA solution for your filer. While Ceph is highly available, it's probably huge overkill if you're just looking to add an additional server to make your storage HA.
At two-node scale, you'll get better and more consistent performance from a local filesystem (like ZFS) on a dual ported direct attached storage array, than you would from *any* distributed filesystem. If the array is out of the question then look to DRBD.
All that said, you should definitely play with ceph anyway, even if you don't need it for this project, it's awesome :-)
