Question 1.
Given the following current configuration, is it possible to expand Array B with another identical 6 drives in Raid 5 and add them to the raid50 array? Effectivly expanding the array?
Question 2.
I know that having to many disks in raid5 is not good. But adding one or maybe two 600GB disk to each "Parity Group", can the entire array be expanded with the P420i?
Thanks!
