Don Leahy, on another website, posted this url for a pdf document
written by an academic in Germany (the pdf is in english),
discussing the future of mainframes.
It is a solidly pro-IBM Z/series document,
but includes some handy info on several sub-subjects (is that a word?).
An excellent overview of z/OS operating system and hardware with explanations of component parts.
I will use it as a response to many of the typical 'what is this?' type questions in the future.
it is an interesting read for a weekend.

Call me an old cynic but as IBM sponsors the University I would expect nothing less. Question is how objective is it |

Nah, I don't think cynic, just someone who fails to follows the old chinese proverb:
better to remain silent and thought a fool,
than to open your mouth and remove all doubt.
why don't you read it and tell us how objective you think it is.
and the Univ was around a long time before IBM.
I posted it here basically because it has a lot of good info. |

I did enjoy an occasional browse through the IBM Journals to discover how (dang) inventive the researchers there were, I mean diddling to within a nano-micrometer of pathway sizes and such....
I found myself in an IBM presentation once and just amazed how far the hardcoded/microcoded multiple CPU stuff went, I knew that 'that small boxes' would never out-class the IBM technology.
And after my introduction to DOD protocols, RACF rules!

It might be a word, but if I had uttered it, I would call it a 'Thompsonism', but feel free to call it a 'Brenholtzism'....grin.... |

I had already read it. There is nothing there that is not readily available in IBM announcements. I agree it is nice to have it one place, but it is basically the standard sales handouts reformatted.

I agree, I don't see what it has to do with discussion but it is a historical fact, just as is IBM has cooperated with the University in Tuebingen and Leipzig since 1999. |

Just wanted to add that with the introduction of the z11 hardware and internal coupling facilities several section of this document are no longer completely relevant.

nevilh,
My apologies to you (and the forum) for attempting to malign you,
instead of responding to your remarks.
you are correct, the author of the article is a strong believer in IBM.
you are also correct, that with the release of the latest IBM hardware,
some of the info in the article is out-of-date.
to the other 99.99999% of us not running on the latest IBM hardware,
the article, as you have so eloquently said:
| Quote: |
| is nice to have it one place |
which was my intent in posting the link.
again, my apologies and my own shame for not articulating my thoughts,
and instead making a personal attack.
(oh, by the way, sorry about kicking your ass on the soccer field today) |

We experienced an odd outage a week ago that makes me wonder where the whole datacenter design concept is heading.
We experienced an enterprise-wide network outage at about 4:30 EST. The switch, and its redundant backup, both failed. All traffic came to a screeching halt. The guys in the command center were scrambling to not only figure out what had happended, but what to do. Our network is outsourced, so a call was placed for support. They accessed the switches and made multiple attempts to reboot them, with no success.
Meanwhile, the command center was trying to switch the workload over to the DR site. But, since almost all applications had been up, they were literally frozen in mid-stream during attempts to write data to the backend databases. They tried to put together a conference bridge, and get everyone on it. Email was out. Internet was out. IM was out. All of their contact lists, documents, and procedures are stored on the LAN, so they were unavailable. Our on-call messaging system couldn't work since access to the call-out details stored in the database were unavailable.
Eventually, after about two hours, some hardware was replaced in those switches and they were able to be re-booted. Everything got back to normal by that evening.
I've never understood the concept of high-speed data I/O over a TCP/IP network, rather than using direct point-to-point hard-wired connections. It's always seemed like a recipe for failure in the right circumstances. |

More and more often $ wins over serviceability. . .
Thanks to the Win-based world, it is more acceptable these days to have a major outage. People have gotten used to having their pc or their network out-of-service.
When more CIO's go to jail for neglect to ensure the availablilty of the corporate data (and there is big $ lost), it may improve. . .
Ah, where will it all go. . .  |

| Dick - agreed. They spend zillions on the core then let it down with some hair-splitting for other perceived 'non-critical' elements. Kind of like wallpapering a Ferrari. |
