Linux On Big Iron
panker writes "eWeek is running an article about a company who converted their IBM mainframe into a Linux email server. "The technical support manager at Winnebago Industries Inc. recently oversaw the deployment of Version 7 of SuSE Linux AG's Linux operating system on an IBM zSeries mainframe to run his company's e-mail server supporting 700 users."

By the way, if you are thinking of taking the RHCE course 300 (fast track for UNIX proficient people), I really enjoyed it.

It's frequently said that Linux is not stable enough for mainframe systems. It's also frequently said that mainframes have been obsoleted by smaller, more powerful computers.
I am quite relieved to see that Winnebago has challenged the "norms" and put Linux to use on a mainframe. Linux is commonly used for mission-critical software, like the Linux server sitting next to me that handles our company's mail, but to see it doing something mission-critical on a mainframe is quite impressive.
Good work, Winnebago.
In the end you have a couple of boxes that runs E2K.
Yes, that was a full stop.What these guys are doing is running Linux under a single VM instance. It will cost them serious money because Linux for these boxes isn't cheap. However, they pay only for the first instance at their shop.
I have gone through the price options on W2K Enterprise Server, Advanced Server and Professional with Exchange Server and so on. There is *no* way that we are not talking serious cash here and that is for s/w alone. MS recommends that you dedicate particular systems for certain functionality like E2K - which is great but this costs.
The end result here is that you say that your company is planning to purchase. Come back when everything is working and tell us how much it really cost.
IBM has consistently given me the best support I've found anywhere. They're patient, competent, and skilled.
The CE's I've dealt with have all been very professional; and have displayed none of the behavior you saw.
In one case, I even had a tech from supportline call me back weeks after he'd already solved a problem for me, to tell me about an alternate method he'd picked up from one of the more senior people. He'd used it on another customer's problem, and called me back to let me know it was an option that I might prefer if it came up again. Now that's service.
Hot Damn! It's the Soggy Bottom Boys!

Same here, last June. And when I took my Linux on S/390 training in December, I was in class with people from a major online bill payment company, a major auto insurer, Canada's DOD, and many others. Most had already deployed it and wanted to see what they hadn't figured out for themselves yet.
In August, 2000, I sat next to an IBM'er by coincidence on a flight. He saw I was reading the "Linux for S/390" RedBook. He said I'd become a "demigod" if I get into that. I've already gone thru one consolidation project, starting a second one on Monday in NYC, and have a third one queued up, waiting for me to finish up in NY. It seems we recently gave a customer a server upgrade plan, and they replied, "what, no Linux?" So we're redoing it as a consolidation plan for Linux on S/390.
I'd say Linux on S/390 is picking up steam big time. When I spoke to a friend about this setup, he replied, "Wow, you finally sound like one of those mainframe IBM'ers we used to make fun of!" Of course, he still has no reply to the argument that I can reduce just about any single data center to a couple of 48U racks, and give all the servers five nines.
