True, but who says Oracle is wanting to go up against the big hardware vendors on a hardware basis only? HP sells hardware but doesn't really step into the software services that Oracle offers.
You do know that HP owns EDS?? You don't think EDS doesn't run/install Oracle DB/Peoplesoft/Oracle Apps/etc. for folks for a fee? Likewise IBM Services does the same thing? What do you think Oracle's Consulting and Advanced Support do for folks?
Oracle isn't talking about adding value "on a hardware basis only". They are talking about being a "single point of contact" for some significant piece of someone's business IT operations. Either as a system integrator (it comes out of the box like an XServe but with a full application stack so perhaps more like an iPod. ) and/or as the box's operator.
So it is about becoming primary contact point for the rest of the pieces of in the puzzle.
Oracle may just want a small portion of Sun's hardware business and not develop those monstrous servers. It seems it didn't work well for Sun.
It is doubtful that the very large servers and their non linear pricing were not profitable. IMHO, where Sun screwed up was in two points mainly to do with the smaller servers and machines. Plus a 3rd which probably was more about execution.
First, they didn't do a x86 line and/or hobbled Solaris-x86 for far too long. There was a period in early 90's when if Solaris-x86 had the price point it has right now and they had widely pushed it into the universities (at the "free" price point) that Linux wouldn't have gotten as hot as it did. Sun eyeballed SGI's expensive workstations and wanted that kind of markup too. That expensive workstation market evaporated. [ At least Sun had a x86 version. There was no other large Unix vendor that had a port. ]
Over the last 2 years Sun's x86 servers have had huge growth. In part because it is so small to start so not hard to do 100% when starting from scratch but they could have been in the game sooner. While HP and Dell are going to sell some Solaris-x86 boxes... they aren't going to push them as hard as Sun will.
Sun made the mistake of not doing x86 in part to protect the more profitable lines. Long term that is doom. That's like Apple not selling iMac so as to "protect" the margin on Mac Pros. Or not doing a iPod Shuffle to protect the iPod Classic.
Second mistake was related and that was doing "embedded"/"workstation" chips like the IIi/IIe/IIIi. So not only don't do an x86 workstation but come up with a chip that only would have to compete head-to-head with an x86 on price/performance. I know IBM has PowerPC and POWER split in the 90's but they had Apple on the PowerPC wave. In terms of units sold Sun wasn't going to do anything like Macs sold in terms of volume. And now forget it. Xbox and PS3 ... yeah right. Maybe better folks on the more server based SPARC cores would have let them get better stuff out the door quicker. Instead they were somewhat habitually late with all of their chips. A bit similar to the situation now where they have Niagra and Rock in development at the same time. Two slightly different approaches which costs alot to keep going in parallel.
The third thing was they paid alot for StorageTek. Even more (relatively speaking in terms of revenues/profits) for MySQL. Sun had money to whether the storms. They have burned through alot of it without huge payoffs. [ Nothing like the bang-for-buck they got out of buying Andy B's company and jumping into the top end game of midrange x86 servers. ]
Sun had $7 B and spent $4.1 on StorageTek. Similar issue, aiming more at big flush "mainframe" like accounts when the growth in storage is more rapidly growing at the smaller end of the pool. Now they have the unified storage systems and are leveraging flash in a leading edge way.
In short, seems like Sun often seem to try to get out of trouble by trying to head to markets where the profit margins were larger instead of dealing with trying to deliver something more effective where the competition was steeper. The "we'll just be slightly cheaper mainframes" approach. That doesn't work. Don't think Oracle is going to buy into that trap, but we'll see.
To tie back in with Apple. That whole "we'll just go to higher margins", no matter where the median price of computers are going, is a very similar trap. Similar effects too. Back in early 2000's Sun had tons of money in the bank; just like Apple has tons of money now. Long term though it was a bust to blow off the lower priced competitors over protracted period of time.
