Not easily; it's in a separate enclosure.  It does have the standard
dual-port SAS connector on it, and we are running it dual-ported
(active/passive, not active/active, at least for the moment).

I don't have any way to confirm this.  We're just using these drives
as ZFS cache, so it doesn't make a huge difference to us one way or
the other.
