This article quotes the acquisition at around $6.5 billion(http://www.reuters.com/article/newsOne/idUSTRE52H1GS20090318). StorageTek acquisition was $4.1 billion(http://www.infoworld.com/article/05/09/01/HNsunstortekcomple...) and MySql AB acquisition was around $1 billion. That makes $5 billion. So is rest of the Sun worth $1.5 billion? Clearly, it seems that these acquisitions have decreased Sun's valuation, rather than increasing it. Also, I didn't see any point in buying MySql AB for $1 billion.
