HP Embraces Linux for its Toughest Servers

Colmao writes "Investor's Business Daily wrote up an article interviewing Martin Fink, the head of HP's NonStop Unit. From the article'In a move that suggests Linux is finally ready for prime time, Hewlett-Packard is giving the free software a bigger role on some of its toughest servers.' NonStop servers are HP's most costly machines. They are designed to be always on, mission critical appliances. They are used to run some of the world's stock markets. Linux is making big moves in the datacenter and getting some much needed exposure."

Re:Is that "NonStop", as in Tandem?

I would be very apprehensive about trying to graft the NonStop technology into the Linx kernel. Running Linux as a process under Guardian, just like IBM runs Linux under VM, makes a lot more sense.

HP Needs Linux to Survive

[reporter]

HP Unix was distinctly inferior to IBM's AIX, and moving to Linux is a way for HP to (1) jettison its own inferior product and (2) avoid the R&D costs of developing a superior operating system (OS). As for #2, there are 2 aspects: (1) feature development and (2) reliability. The vast army of open-source developers have made Linux a feature-rich OS that rivals (and likely now exceeds) IBM's AIX.

Further, IBM has spent enormous sums of money to ensure that Linux is reliable. IBM will soon discover that this aspect of Linux is the Achille's heel of open source. By using Linux, HP essentially gets a free ride from IBM and need not spend the money to ensure that Linux is reliable. IBM has already done the work.

I can already hear the grinding of the reduction-in-force axe at the OS department of HP.

First, I have worked for both HP and IBM.

Even though I am a die-hard Linux coder, I would say that HP-UX is NOT inferior to AIX. I have worked on both, and I would say they are the same. What really matters is the support that the company offers. Can you count on the company to provide patches quickly? Is the hardware solid. Once again, I think that both companies make good equipment (but on the lower-end, I would only buy from one of them).

As to the achilles heel of open source, IBM is much brighter than you about this. Several things:

1. Other than MS, ALL actively supported OS are money losing operations. Even for Apple, they lose money. Once active support stops (i.e. about 6 developers), then the company makes money (HP has made millions off HP-3000 once they stopped active support). The OS exists to sell hardware.
2. HP has been contributing to the OSS world for some time. They may get a bit of a free ride, but they will also have to contribute more or will be unable to say that they offer the best support. IOW, IBM and the other companies will be having "free" rides.
3. It is EXPENSIVE to create an OS and then run in on only one platform. That is how MVS/CICS/etc is on the mainframe. Or how OS-400 on the as-400. Or AIX on power-pc systems. Linux is on all of their systems (and their competitiors). Soon, Linux will be #1 for IBM due to ability to scale across the hardware. If an Intel does not cut it, then Power-PC it. If needing more, that AS-400, followed by the big boy.

Yes, HP will get some free software, but IBM is getting 10s of millions of support from everybody else.

As to the axe, well it will fall in all the major tech. companies. They are all pulling a fast one. In the past, they would lay-off in the states or in EU, and openly hire in India/China at the same time. Now, they are going through fast up and downs. Well if you watch carefully, the up is hiring in India/China, and then 6-9 months later, they announce a slow-down and lay off. You are simply looking at the shifting of ALL tech companies to overseas. IBM and Sun will soon announce another round of layoffs. While the American economy is still lousy, so you will not notice.

Re:correct link

[FireAtWill]

Thanks for the correct link.

Having found the correct article, I'll be interested to see if this ever sees the light of day. I did spend a bit of time working on Tandem Non-Stop systems (since acquired by Compaq, and hence, by HP).

Working on Tandems was kind of like visiting another planet and seeing how an alien race might do operating systems. Hardware-wise, everything is redundant - from the CPUs, to the power supplies, to the system bus. Supposedly, a failure in any one component couldn't bring the system down. Everything was designed to survive a failure. Creating a fault tolerant system was supposed to be easy - except that all the software had to be designed to respond appropriately to a failure event.

The system could definitely use an upgrade using Linux. It was limited to eight character file names (no filename extensions) and you could use directories and subdirectories - only. There was no such thing as a subdirectory of a subdirectory. Just two levels.

The operating system was built around a messaging system that was fast enough for ATM transactions, but was useless for batch type data crunching operations (unfortunate, since somebody at this shop had selected it to do exactly that task.)

If they're thinking about this on the same lines as the original vision of the NonStop operating system, the version of Linux that comes of this will be completely non-applicable to any hardware but HP's. Everything will need to be rewritten/tweaked. Starting with Linux will help their other deficiencies, but will result in a really weird Linux derivative.

But in the end, IMHO, the whole concept is flawed because, while interesting, it only addressed component failure and not disasters such as fires or tornados, etc. At the same time I was working on this system, I read a story about a mass transit system in Denmark automatically (and successfully) failing over to another system in another city as a result of a fire. That seemed far more robust. And those systems were running OpenVMS.

What is Non-Stop

[minniger]

These are systems that are really pretty cool. And really freaking expensive.

They have nothing to do with HP-UX or Unix of any kind. They are Tadem machines (feel free to look that up).

These are rather slow but super reliable machines with a bizzare OS that has had features for decades that mainstream os's still don't have. Take the current clustering and grid tech and meld it all together and you get something like the tandem. The company I work for came out of the tandem space. The typical intro to the machines for new hires is to note that you can smash one with a sledge hammer and you won't lose any transactions.

Who uses these things? Banks, Banks, Banks, Airlines, Governement, Dell, etc...

They (HP) have been working on a unixy layer to run on top of the tandem os for a number of years now. Apparently this hasn't been going too well. Sounds like Linux might help them do something similar to IBM and the VMs on the mainframe.

Re:NotStop != non-stop

[frodo from middle ea]

Originally The System was called Tandem, which ran an OS (or rather kernel )called "NonStop Kernel", they even have a database called NonStopSQL.

Later in S-series servers, the System got renamed to NonStop, the kernel got renamed to Guardian.

About loosing CPU,Memory/System Bus you are not even scratching the surface....With 2 systems operating in Tandem (hence the name),, you can even loose an entire system, and the other one takes over, and these 2 systems can have 2 geographically remote systems in tandem, giving you complete fault tolerence.

These systems talk to eachother over a proprietory network stack (defi. not TCP/IP) and do health monitoring. And uptime is measured in years, not months...
