Hi Mike,
SUSE doesn’t normally comment on products and features that have not yet been announced.
If you visit SUSE Enterprise Storage and ask for a 60 day Free trial, you will be able to download an Evaluation copy of SUSE Enterprise Storage 4 x86-64.
The links on the above page currently point to the SUSE Enterprise Storage 3 Documentation. I’ll report that to SUSE and get it corrected. In the mean time, look here for SUSE Enterprise Storage 4 documentation.
