Open Blade Servers?
Greg Smith points to this ZDNet story on new Intel chips aimed at blade servers, writing "Proprietary blade servers are coming on strong from IBM, Dell and HP. Where are the open blade servers? How did Google roll out 10,000 servers at such a low cost?"
Imagine a beowulf cluster of those...
Really, though, the fact that this blade server consumes so much less electricity would be very meaningful to me. The server room at our school was not intended to be a server room. The wiring also is lacking, and every once in a while the breakers go pop!
BTW, is it possible to use this in a laptop? Just imagine the power (or less consumption thereof) if you packed two processors in parallel on a laptop...
I'm the Devil the Windows users warned you about.
The usage of Pentium IIIs for these monsters of serious computing only goes to show how much of a badly designed marketing ploy the Pentium IV is.
Well, I am sure free advertising has a lot do with the Google roll out.
The <insert powered by DELL,COMPAQ/YOMAMA) tags will start appearing all over google.
I also reckon they were free or at pretty much close to cost. Companies know what there doing. Cost on that kinda margin is probably at 200 bucks a pop straight outta the factory when you consider markup is about 500 percent on computer parts. Remember buying in bulk is power.
Example, you can get a pc on pricewatch with a 20 gig drive, 256 megs of ram, and a giga or more processor for, 250, so think about it.

The Revolution Will Not Be Televised
Yes, and RISC processors will outperform comparable speeds of Intel and AMD chips.....But anyways, Intel's are pipelined as well, goofball. AMD just seems to do it slightly better. However why Intel outperms AMD is because they are able to jack the clock speed up better than AMD seems to be able to. I'd bet they're purposefully decreasing the effectiveness of their pipeline to boost the clock speed. Anyways, the point of the article is that Intel is making Lower Power chips. So their main counterpart would be Transmeta, or say Motorola for PPCs, or SUN, et cetera, anyone of those are players in this particular arena.
Karma: Not Particularly Funny.
I'm currently involved in a server consolidation project where the customer has dictated that they want to see some blade. Our primary platforms are some kickin' Intel servers (8-way 1.6GHz, 8GB RAM, max 16-way 64GB) running VMWare ESX, but the customer is insisting on seeing some blade. I am personally unimpressed by them. You need to make sure that your apps can and are built to either cluster or failover cleanly when you get blade involved. Or just not run any mission critical stuff on it.
I prefer the VMWare ESX on our nearly-non-stop Intel hardware, the x440.

Server blades also share a power supply, cables and memory
Normally, redundancy is a high priority. Is the savings in hardware and electricity worth the risk of losing (say) 10 machines because one power supply failed?
Well, I cannot believe that there are no pictures of those 10,000 x86 boxes that Google has. C'mon I bet there are at least 50% of those Google employees that check /. regularly.
Anyone?
The really interesting thing is that as it is used it appears to be faster than the same clock speed pentium. What? you say. How can this be, since transmeta has a rep for being slow.
Well it truns out that for scientific applications, ones where you tend to sit in tight loops a lot the thing is faster. It's meta chips compile the intel instruructions into its internal processor code. Once the overhead of compiling is over its faster internally than a pentium 3
The reason it got a bad rep for being slow is that for GUI type applications where the code is running all over the place and never doing the same thing for very long, it loses out.
given the incredible stability (120 days no reboot), the increacing speed of the transmeta chips (1.2 Ghz), and the extreme low power, high density and no need for special cooling these things may revolutionize scientific and industrial computuing. But they may not dent the desktop market for raw power in GUI applications.
Some drink at the fountain of knowledge. Others just gargle.
I don't have any data to support this, but part of the excitement about PICMG 2.16 was that it (in principle) should allow much higher throughput than CompactPCI. I've heard vendors talk about 20+ Gb/s speeds. With potential speeds like that, I don't think anyone in this sector of the industry thinks performance will be an issue.
Each blade vendor has to build the proper magnetics onto their board. Essentially the entire blade will have a single I/O device driver: to the ethernet backplane. There are opportunities for increased reliability and performance gains because of this simplified design.
The company that designed CompactPCI and the company that designed this ethernet backplane have recently merged into one (http://www.pt.com). Also, every bigtime telco chassis manufacturer (eg. Motorola, Sun, Lucent, Intel, etc.) have bought into this technology.
So my question is... who's gonna bring this to the PC world?
Applications?
1. Citrix farm. They're NOT disk intensive. You can do load balancing on them. If one goes down the ICA client only has to hit reconnect. .. back up no biggy, nobody sees or knows the difference.
2. Web service farm. One server goes down (MS), kernel panics for some reason...remote reboot
3. Novell (or NT) clusters. Exchange or Groupwise. Box dies / need to upgrade..
4. Home control system..Building control system. have 2-6 blades controlling different things..
there's a lot of benefit from cheap blade dual proc boxes..
= Grow a brain...
The notion of "open" makes sense for hardware, although it is slightly different than from software. "Open" hardware that is documented, hardware that conforms to standards, hardware that has well-defined interfaces for software, hardware that is at least licensed under reasonable and non-discriminatory terms. RS232C, parallel ports, PC104, PCI, ISA, USB, IDE, etc., all can be considered reasonably open. Stuff that comes only from a single company, requires proprietary drivers, etc., is not open.
An "open" standard for blade servers would be nice. And, in fact, there are such standards: passive PCI backplanes, networking backplanes, and EuroBoards. Look around the web--there are plenty of systems to build open blade servers on--servers that are open in terms of both hardware and software.
