[ceph-users] Re: How big an OSD disk could be?

A good mix of size and performance is the Seagate 2X14 MACH.2 Dual Actor 14TB HDD. This drive reports as 2x 7TB individual block devices and you install a OSD on each.

My first thought was, wow quite nice this dual exposes itself as two drives. I was always under the impression that it was just one single drive with just more iops. But come to think of it, with such a solution you do create a failure domain that ceph does not know about. With the default host failure domain the only problem is that you have an increased risk of 2 drives failing at once. Is it possible to configure this drive whether it exposes itself as two drives or just one bigger-faster one?
