We have a Server in our office with an Adaptec 2820SA RAID contoller in it, and since the day we got it its been purely excellent.
However, we recently wanted to increase the size of our storage options and have bought 4 x brand new 1.5TB drives for a new RAID5 array. But when I went into the controller to configure it, The drives were not "available" to create an array.
It seems like the controller, despite having 8 SATA channels, is only capable of 1 array at a time.
I have tried googling this theory with no result. Is anyone able to confirm this for me?
