I read both articles. Intriguing. No wonder he goes under a pseudonym. Either "Paul Murphy" or myself is in fantasy land. I'm sitting at a client site with 5 IFLs on a z9 running several hundred linux servers. Most run Oracle, others WEBSPHERE, DOMINO, open source. Our users are happy. All new oracle apps are going to run on the z9 - no physical server purchases.
Our 5 IFLs have plenty of headroom. The client recouped the cost of the box within 18 months mostly around license reductions. The horizontal growth with Oracle is great. With a license reduction from a lot to just 4, the initial project was self funded, almost. All new servers for other projects benefit from this. Same will hold true for WAS. Management is happy. Techs are happy. Apps are happy. Users are happy. So what's not to like? Why compare unreliable PC hard drives to reliable SANs, etc? If physical servers are so great why is this environment rife with challenges? No rack space? Power costs? Server creep? Unmanageable server farms? Staffing issues? Backups - don't make me laugh. Disaster recovery? - don't make my cry - we solved DR, what, in 1985? His argument about false metrics is just specious. Well, back to fantasy land. Oh, I suggest that if you have the opportunity present some of the success stories in our world. I'll be happy to discuss my success stories. But I will concede one major point: linux on z series is not for everybody.

The number of misstatements and outright errors in the first Murphy blog are too numerous for me to attempt to address in this note. He makes the all to common mistake of attempting to compare wildly different system architectures by comparing the processors' Mhz ratings...and this leads him to the erroneous conclusion that a Dell 1.4 Ghz 4 way PC will have the same throughput as a z9 system....;-) However, for some *real-world* examples of consolidating Oracle onto Linux running under z/VM, please take a look at these presentations: 1) Total Cost of Ownership (TCO): Comparing System z and Distributed Platforms (http://www.linuxvm.org/present/SHARE109/S9265cfr.pdf) 2) Choose the Wrong Architecture and Waste Millions - A Customer Case Study (http://www.linuxvm.org/present/SHARE109/S9205mp.pdf) 3) How to Rise Above the Challenges of Deploying z/VM and Linux on the Mainframe and Thrive (http://www.linuxvm.org/present/SHARE108/S9230.pdf) ...pay particular attention to this one... I have some others I can send you as well, if you would like them.
