Mark,

That’s pretty much spot-on, although it’s a matter of semantics as to whether all the credit goes to the head node or not.

What did Microsoft get? I assume the hardware platform (EMC and Dell?), customer base and Ingres are not of much value to them. Patents, people, engineers and the glue code that optimizes queries on the head node has value.

Performance should be much faster with SQL Server on each node. Microsoft hash join is much better than Ingres (async IO, dynamic skew handling, …). Their star join optimization is better than nothing, but about 15 years behind Oracle. Informix XPS has the same optimization.
