Linux Reference Architecture document
Hello all, I am finally getting to the point around here where I can actually mention Linux, especially on S/390, without getting major resistance to the idea. And there may be a major business case waiting in the wings. But I digress Does anyone have a good Reference Architecture or Best Practices document for all (or one) platform(s) that I could modify to suit my own purposes? I am already late to the party and am looking for ways to pick up speed and to set the proper strategic direction. Granted, there are a lot of variables (and opinions) in documents of this sort, but I do not even know where to start in the development of my own. Hence my request. Any assistance or pointers would be greatly appreciated.

Re: SuSE vs Red Hat
A week ago, I asked if anyone had a reference architecture. I only got two replies. One was an excellent set of installation documentation and the other pointed me to websites. I'll ask again, a little differently this time. I am looking for best of breed on all platforms for the variety of things they support. (i.e. RedHat vs. SUSE, Apache vs. Tomcat vs. WebSphere, etc.) Opinions are fine. Do the recommendations above change depending on platform? The replies to not have to be fancy. I'm just trying to provide recommended choices here without the learning curve, as Linux is about to show up here in several flavors on several platforms. I'm not looking for a free lunch, just a menu for the food for thought.

The choice of operating system should be driven by middleware you want to run and the level of support you need. The vast majority of IBM middleware, for example, is supported on RedHat and SUSE only. As you say, SUSE is ahead of the curve. RH is a bit behind them, but I expect they will catch up. (Hey, money is money and bidness is bidness.) If everything you're doing is open source, then availability of support is really the only issue. And, if your company has chosen to fund in-house support instead of commercial, then the choice is entirely yours. And don't let anyone convince you that any of the above is "free". It isn't. TANSTAAFL. There ain't no such thing as a free Linux. (Apologies to Mr. Heinlein, his heirs, and assigns.)

Re: Anybody read this book?
I have the book (won it a year ago on the zJournal Quick Quiz) and it was very interesting reading. Mind you, I do not have z/VM or Linux here yet and at the time was looking for good arguments to make a case for them. The book certainly provided enough of that. For the experienced VM/Linux types, it may be just like reading someone else's experience on installation/implementation. Can be interesting, but the reader has to decide.

It is really a normal CPU which has be somehow "crippled" so that it can only run a Java JVM. What this does for z/OS is allow one to have a CPU dedicated to Java work which does not count towards other (OEM and IBM) software costs. They are only announced for the z890 (maybe the z990 - I don't remember). Being "Java Only" IBM believes that they will therefore only be used for the new "e-workload" (to coin a phrase) such as WAS. If we get one, we will very likely convert some COBOL to Java (if applicable) just to releive the load on the "more costly" CPU engine.

Re: How do you compare workloads on the IFL's to other hardware platforms?
Try TCA (total cost of acquisition). How many midrange boxes (or processors on those boxes) does it take to achieve the workload desired? Compare the economics of that hardware acquisition versus "x" number of IFLs. Next, be very sure to determine the number of software licenses for the midrange boxes. If they are "per processor", zSeries may prove economical on that front. Add in support costs for the midrange hardware. On zSeries, it is just the IFLs. Determine *if* the cost of software licenses is the same on zSeries. For instance, Websphere is licensed "per processor". On a midrange platform, you may need 64...on a few IFLs, well, you get the idea. Any server consolidation that could take advantage of the IFLs if they were present? However, above all, benchmark/pilot the zSeries initiative to see if you can extrapolate some of the numbers. And, as always, continue asking these types of questions on this list!

Tom, Get your IBM local account exec to put you in touch with the z/Linux advocate for your area. If he scratches his head, email me directly and I'll see if I can run down someone for you. I know that I can get it on trial. They have already offered it to me for proof of concept. Bob Richards -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Tom Duerbusch Sent: Wednesday, November 15, 2006 11:31 AM To: LINUX-390@VM.MARIST.EDU Subject: Websphere trial on zLinux? I was looking at the IBM web pages for a trial of Websphere for zLinux. The only trials they had were for Windows and Linux (Intel). So, is there a trial for Websphere on zLinux? And if so, what are the procedures to get it? We have a project on the Open Systems side, JAVA based. Seems to be in house code. But then, it can't be much, because management is only looking for a trial. Anyway, they were looking at Websphere on 386, when they started looking at Oracle Application Server. Then things started getting bogged down in acquiring the hardware for the trial. Hardware? I have a z/890 with an IFL (running about 10% utilization) So I started bringing it up and decided to try it. My guess is that I can bring up a Linux machine (I already have some 17 of them), and install Websphere and hand it over to development, in a day. We can decide what platform the application should reside, later. If there isn't a trial available for zLinux, then I don't see how we will ever have Java applications on the mainframe (which, being Java, may be a good thing).

WAS on zAAP versus pSeries
Does anyone have an idea how running WebSphere Application Server on z/OS on a System z zAAP would compare to running it on "x" number of processors of a P595 at 1.9GHZ?

Re: WAS on zAAP versus pSeries
Jim, Then I am to understand that your guess is probably close to 1:1, all other things being equal and not exactly favoring the strengths of the particular platform? Your other advice is well-taken and I will suggest to the pSeries person that asked me the question in the first place that he follow-up with IBM on it.

Bob: This is a hard question to answer. A z9 EC processor runs at 1.75GHz but you can't really compare z9 GHz to p5 GHz (totally different chip designs). An IFL, a zAAP, and a CP run at the same speed (unless you have a "sub-capacity" CP). Of course it really depends on the total application. If you are doing a lot of I/O (say a database back-end), then a z9 will probably outperform a p5 with the same number of processors. If the application is compute bound (not likely), the a p5 will probably outperform at z9. z9 virtualizes (in the general sense of running multiple concurrent workloads) better than any other platform so if you are running lots of WAS images z9 will probably perform better. You really need to get IBM WAS people involved who can look at your workload and give you specific advise. Of course, talking to other customers who are running WAS on z9 is a great way to get an idea. There are lots of customers running WAS on both z9 and p5 so talk to your IBM rep to set up some calls with other customers!

Re: WAS on zAAP versus pSeries
Jim, Thanks for clearing that up for Tom as I already understood the points. All of what has been posted, however, missed the point of my original question, which was "all things being equal (meaning the same amount and type of JVM utilization on pSeries, IFLs, or zAAPs), how many pSeries 595 1.9GHz processors does it take to match the capacity or either the IFLs or the zAAPs executing the Java code"? Are they 1:1, 2:1, 5:1, etc.?

However that is up to the Workload Manager (WLM) which may decide that running some of the Java code on a CP will give better performance. However, for zIIPs WLM will ensure that no more than 40% of the DB2 workload gets offloaded to the zIIP. DB2 on z/OS is of course priced on capacity so IBM SWG wants to make at least 60% of what they were making without a zIIP.

Re: OK - a really stupid question.
Here is another consideration for this discussion: Until recently, deploying WAS on z/OS was very cost prohibitive, especially with the OTC and S&S costs. However, with the zNALC pricing announcement providing LPAR pricing, the playing field changed. Now you can create and control a WAS-only lpar and how many MSUs you want it to consume. z/OS, its features and some other charges for that lpar possibly drop to single digits (in the thousands of $$$ and are separate from normal z/OS WLC charges). Of course, some good reasons for this setup could assume your backstore (DB2) is on the same platform, zAAPs can be available and other synergies can be achieved (high availability, GDPS, etc.). What is nice about z/Linux and ZNALC is that you now have application, business and infrastructural *choices* that won't break the bank based strictly on processor license cost issues we all have observed on Unix platforms and full capacity-based IPLA product charges under z/OS.

And I hadn't thought about it much, but it would be likely that enabling the zAAP would require a change to z/Linux dispatching as it did to z/OS as well as a modified JVM. Modifying the JVM might be OK. But to modify the z/Linux dispatcher would likely put out "too much" information about how the zAAP is enabled. Right now, that information is rather restricted so that some "hot shot" would not be as likely to try to "fake out" the z/OS dispatcher to get his own non-Java code to run on a zAAP. Of course, this later is just speculation on my part. -- John McKown LEGAL DISCLAIMER The information transmitted is intended solely for the individual or entity to which it is addressed and may contain confidential and/or privileged material.

Re: GDPS/XRC for z/VM and Linux volumes
Ingo, My setup won't exist for a few weeks yet. What I am trying to find out is how GDPS and XRC can provide failover capability to a z/VM - Linux environment. Based on what you are telling me, in an XRC/SDM pull operation, the timestamps for all Linux volumes should be reassembled just fine on the secondary DASD, same as for z/OS volumes. What I really need to understand then is what are my exposures if I XRC the VM and Linux volumes. What is different/lost when compared to a z/OS setup?

David, After reading your reply, feel free to pass yourself off as me anytime! :-) Extremely well stated! And it is exactly where I was going with this thread.

Do you have problems with these > limitations? Other? While I'm not Bob, an observation: The problem here is a common one when having conversations with IBM about virtualization on Z at any real scale. The solution that is offered supports only part of the problem. You've addressed the Linux and z/OS layers, but the z/VM layer -- which is just as important, as it controls the resource allocation to the Linux layer and is directly critical to the cost and ROI cases for having Linux on Z in the first place, is completely left out of the management picture of the solution. If you're trying for a completely managed solution (which is what GDPS is supposed to provide), then omitting a major portion of the solution from the management integration pretty much torpedoes the argument for creating the solution in the first place. If I have to create exceptions to the IBM management infrastructure to *deal with a strategic product made by IBM*, then there is a fundamental design problem here. Having VM be unmanaged in that environment blows the whole premise of completely controllable failover. The same argument applies to EWLM, IRD, and many other things -- GDPS and the tools required to implement really highly-available managed solutions need to be actively cognizant of the presence of VM in scenarios like GDPS, and not treat it as a poor stepchild who can be ignored as a helpless invalid. Treat it as a client, but treat it you must, because it's a critical piece of the plumbing. LPAR isn't an acceptable alternative.

Re: GDPS/XRC for z/VM and Linux volumes
Robert, I do not understand your last sentence. Why would your z/VM systems crash? Is it because they are on DASD that is under XRC? Bob Richards -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of RPN01 Sent: Friday, June 29, 2007 10:53 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: GDPS/XRC for z/VM and Linux volumes It should be noted that, as far as we've been able to find out (and there are still IBM'ers working on it, so this may not be true shortly), z/VM cannot participate in GDPS if you are running CSE, or if you have any DASD shared between two z/VM LPARs. As I understand it currently, if our z/OS systems go with GDPS, and if and when they test the fail-over (which they want to do at least twice a year), both of my z/VM systems will crash. -- .~.Robert P.
