Hi.


I'm thinking of building a NAS with the Norco 4220.
Can someone point out a RAID card (or cards if more than one is necessary/more cost effective) that has the following features.

Hot Swappable drives
Online capacity expansion
RAID 5
SAS (This only because the Norco 4220 uses SAS backplanes as far as I can tell).

Thanks

I use FreeNAS for my personal usage and my clients

I only have 8TB at home to stream the HD video/audio around the house

Where my client has 40TB raw and 32TB use-able space (2TB HDD was used)

Both systems can have more volumes, but not as ONLINE expand. Because:

1st - when you are doing ONLINE expand, the data is at mercy of expansion process it takes a LOOOOOOONNNNNG time, because there are TWO process:

a) increase the raid volume - that handles by raid card - it can be days
b) increase the partition - this handles by the system - it can be days

2nd - If you don't have the back-up, then there is a chance you will loose everything

I would not recommend you to expand the NAS volume but rather add NEW volume so you can see more...

Here is what I did.
