Greeting Overflowers,

What's SQL Server 2008 R2's option to Oracle 11g RAC ? How can they compare ?

I have to utilize cheap computer systems running exactly the same database for mostly read-only parallel/distributed queries.

Regards

mysql seems like an inexpensive alternative on cheap hardware. No OS certification. SQL Server is preferable to Oracle - or perhaps is it the other way round? Should you could list more needs, recommendations may be made.
