Re: Array with two size diferentes hard disk

What array controller?
If it is a Smart Array controller you can set up a RAID1 but this will use the smaller disk size thus you will see 36GB net

1. It is very much possible
2. However, you will not be using 36GB of the HDD with 72GB capacity
If you are keen to win, you should be willing to lose.

thank you!

One question more. When I create RAID1 with two disk, I have one logical drive of 36GB, but 36GB space free. Can I lost free space disk no used?
Sorry my english is poor.

You lose access to the 36GB space until you replace the 36GB drive with a 72GB drive.


ACU will not let you do anything with it. It will not even show in ACU.
