A few notes:
slide 1. striping (aka RAID-0) is not reliable.
slide 3. I'm not sure why you say this would be available in "late
2008/early 2009"
since it is in fact available today with Solaris Cluster, in some form.
But ultimately, your architecture could be described as this:
disk -- server -<iSCSI>- server -<iSCSI>- client
or
disk -- server -<iSCSI>- server -<NFS>- client
or
disk -- server -<iSCSI>- server -<CIFS>- client
This really doesn't make sense as it is far more complicated than a simpler,
and more reliable, architecture which is widely adopted:
disk -- server -<NFS/iSCSI/CIFS>- client
As we've been watching people attempt to implement these sorts of
things, they enter into a new set of failure domains and often do not
consider the implications. If you *really* want Enterprise levels of
availability, you simplify rather than complicate the architecture, and
you reduce the number of failure domains whenever you can.
