"If Oracle is trying to convince Sun customers that it is committed to the Sparc platform, perhaps it is not trying hard enough."
You are seeing it from the wrong angle. The SPARC comparison will be done on Oct. 14. Wait until then for any announcement regarding SPARC. Up until now, there wasn't any pitch about the Galaxy server line and many were doubting about it's future, but now, here it is... Also, OTOH, using Intel technology, Oracle assures continuity to he first Exadata generation. Same idea, many upgrades.
"Interestingly, as Ellison started off his presentation, I could have sworn I heard him refer to "Sun Computer," not Sun Microsystems"
Yes, he did... but since it's soon to be owned by him, I think it's fair that he calls Sun in whatever way he wants to, heh...
"While this may be technically true, there is no reason why the new storage servers embedded in the Exadata V2 product can't be hooked up to other x64 or RISC/Unix servers running the Oracle database and RAC extensions."
Lame. Why hasn't it been done before as a product by someone then, if it was so obvious?
"Right up until the minute that HP starts partnering with IBM and Microsoft to do similar optimizations to take advantage of flash with their databases."
Funny. Let's see how/if that plays out. My take: it won't.
"The storage server portion of this setup consists not of the F5100 flash array that Sun has been working on"
True, not the array, but the flash technology inside the array is relatively the same.
"It is interesting that Sun and Oracle didn't choose the top-end 648-port switch."
What for?
"The base setup includes a rack, one database server, one storage server, and one switch. "
No, there's no rack in the standalone version!... only the systems, racks only begin from the quarter rack configuration.
