  The controller has a limit of 32GB per logical unit.  You can create
one large RAID5 set, but you have to create multiple 32GB logical drives.
(And there is also a limit of 8 logical drives.)

  The ES40 I'm using has 6 18GB drives configured as a single RAID5
drive, but I have 8 logical drives defined.

  I don't know of any other raid controller that would be supported by
the alpha SRM.  The ES40 I have does support a DPT raid controller, but
I was not able to get it to work with NetBSD (and it's not supported by
OpenVMS, which is what the ES40 will be running).
