heh... I haven't had a whole lot of experience with the 1U servers (from any server manufacturer), but the older Compaq DL380's are quite nice and stable... though getting the cover back on can be a pain sometimes.
Of course, a lot of our servers are sitting on shelves rather than on rails in a cabinet... silly colo facility and their lack of cabinets:)
SmartDisk (which I think either bought out VST or something) has a product called the FireWire RAID tower for Macs that allow you to setup four VST FireWire hard drives and a battery, and using FireRAID software to create a RAID array. Since the max FireWire transfer rate is 400Mbit/sec (or 50MByte/sec), performance wouldn't be too bad. Another solution is a larger IDE to FireWire RAID enclosure, like one from MacAlly that supports Windows and Mac OS.
Maybe in the near future, we will see Serial ATA RAID controllers utilizing a PC Card slot that supports say two drives in either RAID 0 or RAID 1, that would connect to drives and powered by either a battery or an external power source.
Software RAID under Windows may not be the most optimal solution due to it's processor overhead, but it's still a somewhat viable option.
The current Latitudes are use a different build than their home user oriented Inspirons... but some of the older Latitudes look, feel and act like their Inspiron counterparts. After dealing with a couple of those, we switched to IBM ThinkPads and those have lasted through a lot more abuse than the Dells.
I bought an IBM ThinkPad T21 laptop for personal use because the amount of abuse that they can go through but also that I can run FreeBSD over half the time:) The only gripe... the T21 at that point in time (P3-800, 256MB of RAM, 20GB hard drive, 14" TFT, DVD-ROM, built-in Intel NIC+Modem and Windows 2000) was quite costly.
Just trying to do whatever a poor slob like me can do... can't do much else since I don't have the bandwidth nor the space to setup an official mirror. Maybe one of these days I can:)
No ATA RAID hot-swap? Are you really sure about it since I did find information that states that ATA RAID is capable of hot-swapping... it just needs a decent ATA RAID controller (you can knock the low-end, aka cheap, Promise and Highpoint controllers off of the list) and a drive cage that supports hot swapping.
The following pages provide information about ATA RAID and hot swapping:

Knowing Microsoft's history of "secure" software, I think OpenGates would be a better name. Not only would it match the first release's security (pre-SP4 that is) but also help inflate Gate's already enormous ego. The last bit is a good thing, right?...anyone?:)

Some Firewire cards have a power connector to provide power over the bus... I've seen one or two use the floppy style power connector and a couple using the hard drive style power connector. I also think the Sound Blaster Audigy Platinum (both the regular and the eX models) use a floppy power connector to provide power for the FireWire ports...
My older computer power supplies don't have two floppy power connectors, but my newer machine does.

I believe the Pentium 4 processor does contain a couple of clockless/async components within the same die as the rest of the processor.
There is a thread going on Ace's Hardware, discussing the same article as well as other articles and references to clock-less computing.
I checked the product page for the XVR-1000 and the product page for the MAJC processor and didn't see any mentions of async on either pages.
The MAJC processor microarchitecture is VLIW-based (which is what the Tranmeta Crusoe and the Itanium processors use, along with other processors that I can't remember at the moment)... the MAJC 5200 contains two processors within the package (kind of lie the IBM POWER4 processor) and definitely has a clockrate.
If you use the media available for Volume License customers, you do not need to activate each license, product key and machine via the Internet, only the retail (and possibly Academic versions) require online activation. Instead, you get a product key and media to install on machines.
I have used the product key and media from our Select agreement to install XP Professional on about a dozen test machines without having to go online except for updates.
The results from uptime.netcraft.com seem a bit hokey (sp?) at times since it does not take load balanced web servers into consideration, network outages, etc. In my case, I had a server down for about under a day to be rebuilt and brought it back up... checked the NetCraft results a couple of days later, it didn't show that the site had gone down.
I know there are some projects/sites that will allow people to submit uptimes sent from cron jobs or agents to a server, which then stores the uptime data there. Of course, that doesn't mean that you can just generate junk data (ie: 999 day uptime with 2934 users).
Maybe we can also line up Jack Valenti and Hollings right after h.r053n... I would definitely pay to see that... so long as none of it goes back to the MPAA or the RIAA monopolies.
It looks like User Friendly has a series of strips, starting here that you may like. Forward a couple days more... the worst thing that could happen to man-kind... mini-clones of h.r053n.
5.0-CURRENT includes SMPng which is supposed to improve MP performance dramatically by knocking away that single giant lock. I have heard people running FreeBSD on a quad Intel processor setup a while ago on freebsd-questions... though I'm not sure how well performance would scale compared to a dual processor setup of the same processor speed.
I haven't been able to fully parse the boot log, so I'm not sure if it is utilizing more than one processor or not, but the thing that the write-up forgot to mention was that it was tested under the S/390 emulator (aka Hercules). I'm not sure what Hercules is and how it work per se... but it's still a huge jump forward for FreeBSD.
I was flipping through this book during my last trip to the local bookstore. I have to say that for the money involved, I really was not too impressed with it. It did not have anything there that the Postgres docs didn't already cover, and many of the examples were trivially easy. Now while the docs have the same problem, they are still free:)
The book isn't too bad, but a lot of it is stuff from the on-line documentation, mixed around, added a little spice, and published. For me, it's good enough and small enough to carry around with me along with other books to read casually or when working away from the comforts of a cube (well, compared to a server room or a colo cage).
I'm using Postgres extensively for development at work and I still use a little MySQL at home for some unrelated projects. Each one has its place, its not fair to pit the two against each other.
I definitely agree with the last sentence... the same goes for any similar items: Linux and FreeBSD, Sendmail, Postfix, Exim and qmail, Perl and Python, etc. Choose the best tool for the job.

A power supply can continue to provide acceptable power to the motherboard and the rest of the components, but depending on the load and the fan speeds (all of the case fans have temperature sensors to adjust the fan speed as necessary) the voltage may or may not fluctuate outside of the acceptable range.
In the case of the 430W power supply, the voltage captured by the monitoring software got outside of the slightly modified safe voltage range when the server was under a lot of load (all of the hard drives were cranking and both CPUs were pegged at around 90%). All of the fans that were monitored were running at full speed... The 5V rails were kind of fine and was able to provide the power needed to keep the processors crunching, but the 12V rails (which power the hard drives, fans and other items) wasn't fairing so well. Instead of spending a lot of time researching, we replaced it with an Enermax 550W power supply and it seemed to help keep the voltage within a comfortable range. The 430W power supply was not wasted but used to replace an older 330W power supply that we know couldn't handle multiple 10K RPM hard drives and dual P3's:)
Oops... One of our Unix servers is a Dell desktop that was used to run FreeBSD as a test DNS and Samba server that ended getting used in our production environment since we couldn't get another server shipped in time. It has been quite stable and it's a backup server to our Sun E450.
Pretty much it's a way for those who want to transplant older J# code (looks and breathes like Java but doesn't quite taste or smell like Java, more like 6-day old sludge in a bottom of mug) into.NET.

Personally, I think that the version 1.4 of the JDK/JRE/JVM is quite nice, peppier than it's older siblings, and is the bytecode created is a lot more portable than bytecode produced in.NET (even with the Rotor CLI, since that is only a small portion of the.NET scheme).
