Compaq Array 221 and U2

[naturalgen]

I have a fairly old system. I have Smart Array 221 with an external scsi connection. The internal is connected to a series of scsi drives.

I recently got a u2 storage - can I connect this to the external scsi connection? Do I need to by another controller board for this?

What used controller do you recommend buying - another 221?

You can use it on the external port, but the 221 is a single channel controller. This means you can't use both the inside and outside at the same time.

Look at getting a 3200 so you can use both channels and will not have to lose any date during the upgrade.

I am sorta in the same boat, wondering does the 3200 use the same cables as the 221 for the internal drive cage hookup? Or do I also have to get a new cable for that? The 3200's I have seen on Ebay look like different connectors than the 221..

Looks like they are both LVD to me!
3200

221

Wide Ultra2 SCSI

Yeah, just found out the ones I was looking at didn't have the daughterboard needed to attach internal drives. Now just researching on whether the 2-port daughter card disables both external ports.
