IBM Leaks Details on New Mainframe 185
Mark writes "Big Blue inadvertently revealed details about its new z10 Enterprise Class mainframe set to launch on Feb. 26, as well as details on z/OS v1.10, a new version of the mainframe OS due out in September. 'According to an internal IBM document obtained by SearchDataCenter.com, the z10 Enterprise Class will come in five different models and feature 64-way chips, compared with the 54-way z9 mainframes and earlier 32-way models. In a conference call last month, IBM CFO Mark Loughridge told investors that the z10 would have 50% more capacity, which indicates that it will probably tap out at around 27,000 million instructions per second (MIPS) at the top end, compared with about 18,000 MIPS on the previous z9 Enterprise Class.'"

The things they share are not visible to the user as they are hidden behind the instruction decoder. You can see some evidence of the fact that IBM are trying to lower costs by sharing a lot of the design between the two lines though from certain new additions to the POWER instruction set, such as hardware support for Binary Coded Decimals (useful in high-throughput financial systems and present in the mainframe line since the 1401 and 700-series, which preceded System/360).

Re:Except the processor... (Score:5, Insightful)
It wouldn't surprise me if the POWER7 either implements a superset of the POWER and System Z architectures, or has switchable decoders. Considering the fact that it's already possible to hot-plug CPUs on systems at this level, I can imagine a future IBM line where the hypervisor allows you to not only partition the system, but also decide which chips run in POWER and which in System Z mode dynamically, migrating virtual machines and restarting CPUs as required. That could be very attractive for customers wanting to consolidate mainframe, AIX, and Linux systems.
One of the design goals of the PowerPC instruction set (a superset of which is implemented by the POWER6) was to easily emulate x86. It would be really interesting if IBM would enhance this emulation support into the hypervisor, allowing customers to run legacy x86 Linux, Solaris or Windows Terminal Server virtual machines on their mainframes.
By the way, this mainframe is one of the big reasons why IBM are so keen on open source. If you run Linux and (portable) open source software then IBM can sell you a mainframe running Linux VMs when you start to outgrow your current infrastructure. The reason IBM owns so much of the (small, but incredibly lucrative) mainframe market was that in the '60s they pushed the predecessors to this system - System/360. They sold cheap minicomputers and high-end mainframes that ran exactly the same applications (and, with System/370, the mainframe could even run virtual minicomputers). They got people using the cheap minis and then presented them with a clear upgrade path. With open source, they can give people a really long upgrade path starting at commodity hardware and going as far up as they want.

Sure, zLinux software can be trivially recompiled for Linux/PPC. But if you're talking about real legacy mainframe code, of course IBM doesn't want people to switch to a cheaper platform. (And I think you mean much higher reliability.)

Most PPC software is written in C, so you can just recompile it for zLinux if you want to run it slower.

They also support partitioning on the hardware level, so you can run z/OS or Linux virtual machines with almost no overhead (something you've been able to do since it was called System/370). You also have a huge amount more fault tolerance with a system like this (take a look at how many transistors on the CPUs are dedicated to error checking, and then start looking at the peripheral systems).

We use them due to ability operate in something called a sysplex. A sysplex is when multiple mainframes share data (known as DASD) and work together. When a mainframe is in a sysplex, you can do all sorts of things to the machine without having to bring your application down. These range from whole operating system upgrades to hardware maintenance and the end user will never see the impact. A sysplex literally is designed to be a 24x7 operation.
You can buy other types of machines that will be more powerful, faster or do operation x better, but it is hard to find a set of machines that are as stable and reliable as a mainframe is (and process millions of transactions per second).
Also, in terms of virtualization - a single mainframe on z/Linux can host many virtual linux servers - enough that you can save a substantial amount on power costs (my org estimated 400k a year in savings in terms of power alone - if the linux servers that are hosted individually on one of our distributed networks went to virtual on a mainframe).

You are spot on. Mainframes exist simply because throwing money and engineering efforts at the hardware/OS level is cheaper than rewriting the massive amount of legacy applications that have been built on them for the past 3 decades.
