IBM: Yes, our zEnterprise mainframe will do Windows

By | November 6, 2011, 8:01pm PST

Summary: By melding mainframes and Microsoft Windows, IBM is looking to consolidate more data center infrastructure.

In what could be construed as one bizarre combination, IBM is planning to slap together its zEnterprise mainframe with Windows applications.

These systems—available Dec. 16—are notable on a few fronts. For starters, mainframes and Windows historically haven’t gone together. In fact, mainframes and Windows have never gone together. IBM is aiming to change that by coupling Windows apps that have to connect to mainframe data. By consolidating these moving parts onto one system, IBM is looking to consolidate more data center infrastructure.

The underlying message from IBM is also notable. By positioning the mainframe as a megaserver it’s essentially telling customers to dump those x86 servers for one tall box.

IBM has been pushing a more heterogeneous environment that melds its mainframes with distributed systems. The theory is that creative mixing and matching can cut costs. IBM’s move also reflects data center realities: Unix, Linux and Microsoft Windows Server are all at play in most enterprise infrastructure. What’s in it for IBM? IBM is looking to pitch its centralized approach over the server sprawl that can happen with distributed systems. Big Blue’s message: You can consolidate infrastructure without ripping out the stack of stuff you already have.

The mainframe-Microsoft Windows concoction will be available for both z196 and z114 systems. In July 2010, IBM kicked off its hybrid approach by combining its mainframes and System x blades. That interoperability has carried throughout IBM’s product line.

Today, IBM’s zEnterprise System can run z/OS, Linux, IBM AIX, x86 Linux and Microsoft Windows on the same hardware.

In the big picture, IBM’s mainframe and Windows combination highlights how it has been able to evolve it z systems, which have been targeted by rivals or proclaimed dead multiple times over the years.

  • Don't Expect Dimdows To Run Fast
    Don't expect Microsoft Windows to run fast on these machines. Mainframes are not known for being very grunty--their specialty is high throughput and high availability. I can see a point in running Linux tuned for mainframes, but putting Windows on them seems like an expensive waste of hardware.

    It isn't actually on the mainframe its in the zBX (blade center beside the mainframe) and will still be on x86, you can already get Linux blades for said zBX extension

    You said "mainframes and Windows have never gone together". I beg to differ, Unisys Clearpath Mainframes have been running Windows, Linux and the Unisys MCP OS on the same Big Iron since 2002 at least. http://www.computerweekly.com/Articles/2002/09/27/189956/Unisys-unveils-ClearPath-server.htm

    Windows? On an IBM mainframe?

    They're getting pretty desperate.

    Maybe it's just time to to admit the era of the mainframe is over. Get a server farm like everybody else.

    @CobraA1 And all the worries that come with that farm. Latest count here ......... 260 windows servers (thanks to VMware), but the core business is running on ONE iSeries.

    Desperate? hardly... IBM mainframes have been selling quite well over the last decade.... Take a look at their counterparts at Oracle/Sun and HP... Oracle has 7% of the server revenue market share(Sun had 30% of the server revenue market in 2000).... HP... losing support for Itanium from MS, RedHat and Oracle.

    Server farm??!! GET A CLUE, virtualization and power/cooling consumption is killing server farms... Pros understand this is a major cost issue...nowadays

    IBM's strategy is clearly aimed at HP and their x86 market lead. A majority of mainframe applications have Windows front ends on them... this is clearly an attempt to bring them specifically under IBM's brand, instead of Dell and HP.

    Since the underlying hardware for supporting Windows is the same... (x-blade HX5)... they hope to differentiate on other items... $0 hardware support costs... centralized operation/problem notification... private network to native mainframe systems....

  • RE: IBM: Yes, our zEnterprise mainframe will do Windows
    @scotth_z has hit the nail on the head. There are many shops that have dozens, hundreds, or even thousands of servers (virtualized and not) with NO mainframe. But there are virtually no shops that have a mainframe that don't also have servers. Many of the applications that run on mainframes are interconnected with those servers (either loosely or some quite tightly coupled). This kind of environment is complex and difficult to manage. The tool sets to manage such an environment have historically been divided, one set for the mainframe and one for the servers, despite several vendors trying to sell consolidated tool sets. Trying to diagnose complex problems has involved trying to get two groups that don't typically work together to collaborate "nicely" to get to the root cause. Good luck with that.

    So, along comes IBM with the new zEnterprise. First, it is a very impressive "upgrade" for the traditional mainframe side of things (z/OS, z/VM, z/Linux). But, now they show us something new, the zBX, initially announcing AIX and Linux, and now Windows. The added values of such a concept are 1) bringing the server side into a notably superior hardware scenario, 2) brining those hybrid mainframe/server workloads under the same management umbrella, 3) significantly reducing the footprint and facility costs in our data centers, and 4) subject to some reality checking, potentially reducing the costs of our server environments.

    However, there is a fly in the ointment. @ido17 demonstrates it: a virtual religious war between the mainframe and server camps. This has been brewing for decades. The reality is that the distributed organization will fight putting their instances inside any mainframe. I imagine there will be some mainframe groups that won't want windows running on their systems, either. This is a sad state of affairs. The zEnterprise is only a server, albeit one that runs multiple OSs. If the zEnterprise proves to be a solid and cost-effective solution, then IT Management will need to set a tone that encourages, right up to forcing, the two sides to work together......please!
