20TB Storage System

[Max Clark]

Depends on whether you plan on crashing or not :)  According to
http://lists.freebsd.org/pipermail/freebsd-fs/2003-July/000181.html,
you may not want to create filesystems over 3TB if you want fsck to
succeed.  I don't know if that's using the default newfs settings
(which would create an insane number of inodes), though.

- This is a big problem (no pun intended), my smallest requirement is still
5TB... what would you recommend? The smallest file on the storage will be
500MB.

To sustain only 30MByte/s across the entire set?  Doesn't really
matter, since even a single disk could do that.

- What would I see better performance with ccd or vinum? So a better
question isn't if I can sustain with 30MByte/s but what would I expect to
maintain?
