Samson,
Here are a couple of links to get you started one link provides an overview another a bit more detail and the last link contains some
whitepapers specifically geared toward the VCE offering. In regard to an exact BOM that would be datacenter dependent, in regard
to competitors I think the information speaks for itself. If you wish to pursue this further the best option would be to contact your local
Cisco sales team.
