Re: [ceph-users] erasure code profile

[Vincent Godin]

If you have at least 2 hosts per room, you can use a k=3 and m=3 and
place 2 shards per room (one on each host). So you'll need 3 shards to
read the data : you can loose a room and one host in the two other
rooms and still get your data.It covers a double faults which is
better.
It will take more space : your proposal uses 1,5 x Data; this one uses 2 x Data
