DISK_C2 is still invalid (this was our former Hot Fix drive), since the rebuild process is not

yet completed.

Now, after having demonstrated with examples 3 and 4 how RAID disk arrays are created

with RAIDYNE (we hope you enjoyed it), we would like to return to the questions set down

at the beginning of this chapter. When planning a disk array it is essential that you have

precise ideas on how you intend to configure the disk array.

To answer this question let us have a look at the delimiting parameters, that is, the maxi-

mum and minimum number of drives. The

maximum number

of physical drives in a disk

array is determined by the number of physical drives the ICP Controller can control (with a

two-channel ICP Controller this number amounts to 14, with a three channel ICP Controller

to 21). In this context, we cannot analyze the many various factors which influence the de-

cision of whether to integrate all Host Drives into one single RAID Host Drive, or rather

create a number of smaller RAID Host Drives instead. The

minimum number

of necessary

hard disks depends on the RAID level you wish to realize.
