Mellanox acquires Voltaire

So I learned a few days ago that Mellanox acquired Voltaire.

This wasn't too much of a surprise, somebody was going to pick them up at some point.  The question is, will someone now go after acquiring Mellanox?  A friend of mine at work noted that Oracle already owns about 10% of Mellanox.
