Killing the Business Desktop PC Softly

Blade PCs
Next up is the blade PC. The challenge is to make sure that the blade PC and the thin client consume less energy together than a typical business desktop. The big advantage of a blade PC is that all PCs draw from the same the power supply, which allows for the use of a more efficient power supply. HP has designed an enclosure that can house up to twenty blade PCs in a single 3U rack mount chassis, all of which are powered by the same redundant 600W power supply. That means that each blade PC consumes less than 30W.
The HP BladeSystem bc2000 and bc2500 consist of:
If you only need a 1.2 GHz Athlon 64, it becomes less clear why you would allocate a blade PC for each user. You might be better off with VDI for example (see below). It might seem like nitpicking, but if you want to add a full rack of relatively modern PCs with dual core CPUs, the system administrator of the data center has to cope with another 12-14 KW (bc2500). If you chose the bc2000 blade, you are looking at only 7.6KW per rack. Clearly there is nothing magical about blade PCs: a 50W blade PC and 15W-30W thin client are not going to save much power compared to a desktop with the same (low voltage) dual core CPU.
Let's take a closer look at the blade PC.
The HP blade PC bc2000
It is a pretty elegant and slim design with a small heatsink on top of the CPU, and two SO-DIMMs for memory expansion. If you don't like your blade PC to be headless, you can add an old Lynx EM4+ video chip which supports an 800x600 resolution when you access the blade PC directly.
Adding a video chip to the blade PC
The video chip plugs into the black "IDE-like" connectors. The second generation of blade PCs still has room for improvement: why use a hard disk if your data is going to be saved on centralized network storage? Solid state drives were probably too expensive at the time of the new blade PC design, but basically the design right now has room for improvement.

well, I know the guy who claims he lowered TCO drastically by switching his business desktop PCs to MacBooks. he says the number of support calls for Macs is zero, while Windows PCs give him trouble after trouble. is this zealotry? I have no idea, maybe he is a zealot but I'd rather wait before judging himanyway, if you guys have any technical questions for him - shoot
I'll ask him, if he sees any real interesting questions - he might even appear here in person
just wanted to let you know that anandtech knows not everything about lowering TCO - there are some interesting surprises out there only a few people know about

I don't have trouble with Windows PC's. The only patches I install are Service Packs. That's it. I don't get viruses or spyware. I do run a anti-virus app and a firewall but that's it. This shit is easy! Block ALL questionable websites at your companies firewall. No pr0n and no downloading. Block all that shit. If you need to download, put in a request stating why you need it. Set up a separate computer with user accounts and passwords that's not attached to the network and let them download from there. Monitor those computers and if someone messes up, remove their access.Pirks - Thursday, July 19, 2007 - link
excuse me, but "I have antivirus", "I block everything with firewall", "I don't let my users do anything on the Net without special request" - this does not sound quite like "I have no trouble", it's more like "I avoid trouble by not letting my users do anything"this is very different from Macs where it's safe to go outside and there's no need to cut everything off. this was this Mac guy's original point - put Macs instead of Windows PCs and there's suddenly no need to babysit your users anymore, he never even bothered to cut their internet access - no need for this with Macs, he says

"put Macs instead of Windows PCs and there's suddenly no need to babysit your users anymore"Thats a great arguement except for the fact that Macs are...
1. largely incompatible with the business world and apps used. Yes some things work fine, but everyone in any office knows that dealing with the few Mac users is a pain in the ass because their shit doesn't work.
2. Expensive as hell
3. If the above 2 problems were overcome (and that IS possible) Macs would be a decent contender and hackers and Viruses would be targeted toward Macs. Right now, Macs are 3-4% global market share, and aren't enough of a contender to bother with.

Lets not forget about . . .4) Limited hardware support.
I am not a Mac fan at_all, in fact I nearly hate anything 'Apple', but if Windows were to vanish into thin air right now, and given the other options availible, I would have to say that Mac OSes are probably the next best polished. It is just too bad that OSX's limited BIOS support makes it nearly impossible to run on 100% of the PCs out there . . . as I personally would not be adverse to running OSX as an alternative to Windows. This goes back to what you said about Macs 'just not working right', this is the feeling I get from anything *NIX; ie: there is always SOMETHING that does not work.
As for your Virus comments, I could not agree more, and while *NIX based OSes may be built to be more secure from the get go, I actually hear more about Linux/BSD machines being compromised than XP/2k machines in a server capacity. My feelings here are that those people who run servers actually KNOW how to setup a Windows machine properly, and do not become complacent. They also do not frequent questionable websites, while 'clickity clickity'n' on 'yes' buttons on every website they land on. They also know the true value of keeping an OS up to date. I actually run XP Pro SP2 withuto any form of a virus scanner, but I will occationally fire up the occational LiveCD (BartPE) and scan with the root disk un-mounted; I have yet to find a virus in the past several years(on my own personal computers), and yet, people I know, who run virus software 24/7 are being constantly infected. GO figure !
Now if it werent for the fact that I get paid very well to remove viruses as a professional, I might actually 'hate' viruses ;)

My mistake. I use antivirus and firewalls at home. At work, I'm not in charge of infrastructure but I know what it takes to make it work. And you can surf legitimately and freely without the need to download and also without the need to go to questionable websites. IF IF IF you NEED to download (IT staff, software developers, etc.) setup a separate computer NOT attached to the companies LAN like I said previously and monitor the hell out it. If YOU are not grown enough to download pr0n or pirate software at home then I don't want to YOU as an employee. The "secret" to Macs is that hardly anyone writes viruses or spyware for them. It's a niche market. Using them in place of the PC at work is smart (IMO) but only serves to NOT hold your employees responsible for their actions. Like I said, I don't those types of people working for me.bpt8056 - Thursday, July 19, 2007 - link
It's the opposite at the institute where I work. While the IT guy has dealt with both IBM and Apple for support, he said that IBM was far superior. He went on to say that there were 12 PC (IBM) and 12 MAC laptops that were sent to the manufacturer for repair. The difference between the two was that all of the PC laptops worked when they were returned and only half of the MAC laptops worked after repair. At the equipment request meeting, he has encourage everyone to consider getting a PC laptop because the level of support between the two were worlds apart and the ~$1300 savings in purchasing each laptop after discounts were considered.I'm glad the switch to Mac worked out well for your guy, but not everyone has the same experience.

Compaq was the mother of the PC? They were one of the two most important companies? What????????????????????They had NOTHING to do with the creation of the PC, NOTHING. Last time I checked, mother's had a lot to do with the creation of their kids.
Compaq was a clone maker. IBM designed the PC, and pushed all the standards for the first decade. Ever hear of PS/2 ports? AT (often incorrectly called ISA) bus? VGA? XGA? Hell, even Winchester drives (Hard disks) were invented by IBM. RISC? IBM! These are things still in use, or at least the terms are. Even Windows 2K/XP were born by IBM, as they were originally known as OS/2 NT (or 3.0), not Windows NT, and perversely IBM funded a lot of the development because it was started before IBM and Microsoft broke up.
Calling Intel a father I could live with, after all they had the microprocessor that was used and eventually took over a lot of the important hardware design from IBM. Easily a more important company than Compaq. Compaq? One of the driving forces behind that great success EISA? Wow, yes, they deserve a lot of credit for that and being a clone maker.
I can't even read the rest of the article after reading that. It's one thing to try to make some seque into the rest of the article, but it's another thing when it's based on absolute nonsense that just makes people scratch their heads. Compaq, the mother of the PC. Unreal.

Uh . . . there was such a thing as an ISA bus . . . PS/2 ports are the din9 plug keyboards still to this day plug into(unless you're using USB of course) . . . Never have I ever heard anyone confuse a keyboard interface, with an expansion slot, but I guess you're living in that wierd part of the world . . . this is not like some PC newbie calling the computer case the 'CPU"; people who knew about an ISA slot, knew what it was, and what it did.
Also, before you get too comfortable calling IBM 'the creator of all', lets not forget that IBM was also the cause of PC hardware stagnation (proprietary hardware at a high cost), and that it was not until OEM vendors got tired of IBM's tactics, that IBM lost nearly all of its PC market share. Sure, IBM pioneered a lot of stuff, and they were responcable for a lot of the technology 'back in the day', but I for one am glad they are no longer 'setting the standard' now days. Now, since when was RISC considered a PC technology ? Never ? Sun ring a bell ? SGI ?
Since OS/2 Warp bore IBMs name, they are responcable for NT/Win2k/XP ?! Now whose taking the leap from reality . . . you sure seem to have an unique outlook on the computer industries past, I'll grant you that.

I am glad the Anandtech Comment box allows you to blow off some steam ... I think your colleagues should thank me now ;-).Anyway, of course, Compaq as the mother of Thé pc is an exageration. However, as we are talking about the business desktop, I do think that Compaq has played a very important role. See stmok's comment, and also, Compaq was one of the most important companies that started very early with selling business desktops, not just plain pcs. More expensive, but easier to maintain and a bit more robust.
You agree that IBM is one of the parents. I am not an historian, but a server researcher/journalist... So feel free to seriously question my history knowledge. Who was the other parent of the business desktop according to you? The main point that IBM and HP/Compaq were both two very important companies when it comes to the history of the business pc.
