The Fireplane backplane in a Sun Fire server is a switched crossbar architecture (I guess that's redundant.... any crossbar is a switch).
Max. throughput per address line is 9.6GBps (that's gigaBYTE), with the potential for 18 address lines (That's on a Sun Fire 15k)
Sun's benefits don't come into play really until you hit the high-end. Once you see an E10k or these days, an SF15k kick ass and take names, you understand just why scalability is so damned important!
But the network, sysadmin, and application teams each report to a different VP.
So no matter what happens, there's always 2 VP's yelling.
If it's a network problem, the sysadmin and app VP's gang up on the network team. If it's a system problem, the network & app team gangs up on the sysadmins.
One thing that all of the various "quality assurance" regimes miss entirely is the value of being able to make mistakes. Risk-averse managers love this "zero defects" kind of environment, because they like the predictability.
Right on.
I work in an environment where "zero impact" is the big buzzword. The end goal is to have our change control list at the end of the year list "Impacting changes: 0". Our "emergency" changes aren't allowed to be above 15% of our totals.
So you know what that does? That makes everyone do the tasks that _should_ be change controlled cowboy-style. Nobody wants to submit the forms to replace a failed disk drive, because you're going to get beaten up for it. So everyone just DOES IT and hope for the best. Application teams roll out new code and bugfixes all the time without change controls -- they don't want to sit on the phone with the VP's yelling at them for being over their emergency change numbers.......
That sort of management style "zero defect" does nothing but drive the business processes underground.
And for the schmuck who said "Real operating systems supports Beowolf"...:
a) It's Beowulf, not "beowolf". Check your literary history.
b) Bullpoop. Beowulf's got nothing to do with the OS, and everything to do with the applications. You show me an Oracle that uses MPI or PVM.
Of course! There's no need. Oracle already has OPS (Oracle parallel server). So yes, you can have an "8x8" cluster of Oracle nodes. Ever try to manage one of those? It's definitely a cluster ---- a cluster*uck!
SMP is a beautiful thing. It's not exactly linearly scalable, but close. And the beautiful part is that if your app is multithreaded, it'll automagically take advantage of the SMP capabilities of the system -- no need to code to the MPI or PVM API's.
Just for sheer "damn, that's cool" factor, think about this: A Solaris 8 CD will boot and install on a single-proc, 33mhz SPARCstation 10 from 1992 all the way through a 108-processor, 900mhz/each Sun Fire 15000.
John Dailey's bought out some of the best BBS doors --- BRE, FE, global wars, global backgammon, all the cool stuff!

Even if safari takes 100% of the MacOS X market (which it will not). It will be a minority browser because macs a are minority of computers.
How many people have downloaded Mozilla?
Who cares anyway? I don't think BMW or Mercedes will ever "take 100% of the market"... what's so bad about being the minority, as long as it's a quality product?
I mean, if the Apple folks were able to port KHTML to OpenStep^WMac OS X from that whole Linux-QT-KDE mess, it can't be that bad, can it?
Let's call it like it is -- Gecko, while a noble effort, is really a failure. It was YEARS late, and completely missed its goal (a lightweight, fast. cross-platform rendering engine). One bit of that (cross-platform) does not a success make.
I have to say, I'm absolutely impressed with Apple's Safari. It's FAST as all getout, and it's the first browser that really makes me think twice about having paid for OmniWeb. I've been using Safari daily since release and while, yes, it has some bugs, it's still better than Chimera, OW, & Mozilla combined. IE also has its rendering issues, and I detest lots of other things about it.
Safari's what a browser should be -- small, lightweight, and out of my face. The interface is slim & sleek, and, like the rest of Apple's software, lets me focus on the CONTENT rather than the delivery.
I really think that's why OSX is so wonderful -- it just stays out of my way and lets me do what I gotta do. And I have to admit, running a DVD authoring program alongside several terminal windows on a Mac (!) is still impressive to me.
Apple didn't buy NeXT. NeXT swallowed Apple whole.'
The mere fact that you have to link to a web site called "lifewithqmail" to point out a patch to a 5-year-old MTA to incorporate even basic LDAP functionality highlights why I use Sendmail.
Sendmail's not NEARLY the problem it used to be. It's a whole lot better than ever before, and it works out of the can without Dan Bernstein's mess all over it.
Philosophically, I couldn't use software written by such a jerk anyway.

You get what you pay for when it comes to LCD's.
I have at home an 18" Sun LCD and a 22" Apple Cinema Display. At work I have a 24" Sun LCD.
I'd take the Apple Cinema Display over the other two any day. Both Sun LCD's have both a VGA and DVI input (the 24" has c-video and s-video as well), but the Apple only has a single ADC (Apple display connector). The apple screen is the sharpest of the three.
Not to say the Sun 24" is bad, but the Apple one is just that little bit crisper. The 18" Sun LCD is crap -- the colors are all wrong, and it looks _awful_ on analog.
Well, we don't have a name for our server room, but our JumpStart server is named Frostbitefalls. (Because it's so f'n cold in there!)
Being that it jumpstarts hosts on a zillion subnets, it has other IP's (and DNS entries as appropriate, such as):
Boris Natasha Sherman Peabody Bullwinkle and, of course: Flying-Squirrel (since rocky was already taken by the west-coast guys... they have a stallone theme goin' on)
The TSM backup server is named wayback. Heh. I thought it was appropriate...
We buy equipment from Sun, HP (both the old HP and Compaq), IBM, Dell, StorageTek, EMC, LSI Logic, Hitachi, Cisco & Alcatel, among others.
I've got Sun equipment on the floor (Everything from Ultra 1's through E10k's & Starcat's), some HP SuperDomes, a few HP WildFire AlphaClusters, some IBM zSeries mainframes and pSeries Regattas, Dell rackmount Linux servers, STK tape silos, EMC disk (on the mainframe only... it bites on open systems!), LSI Logic storage, & Hitachi 9960 storage. The network core is Cisco with some Alcatel stuff on the edge (some Cisco too).
We've got lots of vendors... I just happen to be a primarily Sun sysadmin, so I get invited to the Sun holiday party. All of the above have invited various members of our teams out at some point.:)

If we all reported to the same VP, I'd agree.
But the network, sysadmin, and application teams each report to a different VP.
