Such a configuration certainly works with D1000 arrays, as long as you
are careful to configure Solaris to only access each drive through a
single device-node at any one time.

If you can treat the A1000s as JBOD arrays (ie: don't use the SEVM software
to control them, just the normal Solaris SCSI drivers - in effect treat
them as D1000s), then all will be fine. If you need volume management
in such a configuration, then DiskSuite will do it.

As for whether you can utilise the array's on-board RAID facilities
with such a configuration, I'm not sure...there **may** be limitations
in the SEVM software that prevent it?
