I take it that would be 129+1 RAID-5 :-)
BTW have you done the maths on MTBF with that large a number of disks. A quick
calculation assuming a 5 year MTBF on the disks gives you about a 1.8% chance of
a disk failing on any given day or an MTBF for the array of 57 days - now that's
what I call reliable :-) In fact, it'd be an ideal box to put 'doze 98 on - then
you could coincide the disk replacement with the reinstallation of 'doze :-)
Kindest regards,
