Make that one slot per 8 drives currently: 3ware wants all
drives configured as master, 1 drive per cable.
BTW, be careful if you consider using the 3ware boards in raid1(mirror)
mode,
there's a bug in the current firmware: It does not catch unclean shutdown
in case of power loss, reset, kernel crash or whatever. If a write is in
progress during such an event, you'll get inconsistent data on the disks -
one will have new data already written, the other write may not have
finished.
This is why software raid will do a complete resync of data on next startup
in
this case.
However, on next reboot the controller does _NOT_ recognice this
inconsistency. It happily uses both disks as a healty mirror. If you now do
an md5 sum of the file you were last writing to and repeatedly check the
md5sum, you'll get inconsistant results - 50% of the time, the file will
check OK and 50% there'll be a checksum error since the reads are
distributed over both disks to increase performance.
