A server consists of two 72GB SCSI drives and four 146GB SCSI drives. All drives are attached to a RAID controller. The system administrator has decided to configure all six drives in a RAID 5 array. How much usable disk space will this array have?
A.
288GB
B.
360GB
C.
432GB
D.
728GBb
o or four processors
RAID 5 -> 1 – 1/n
72 GB * 6 = 432 GB
thus,
432 GB – (432 GB/6) =
432 – 72 = 360 GB
