[lustre-discuss] zfs -- mds/mdt -- ssd model / type recommendation

I checked lustre 1.8.8 ldiskfs MDT: 106*10^6 inodes take 610GB on MDT, or 3.5 KB/inode. I've thought it is less.
So MDT size just 'factor three' more compared to old ldiskfs.
How many files do you plan to have?
Alex.

I'm presently at about 10 KB/inode which seems too high compared with ldiskfs.
