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?
