There is no doubt that the zEnterprise enables hybrid computing. Just attach a zBX to it and start plugging in Linux and x86 blades; presto, you’ve got hybrid computing. You can manage this entire hybrid infrastructure via the Unified Resource Manager.
The zEnterprise also has a sister hybrid computing platform, IBM PureSystems. Here, too, you can add in System x and Linux or even Power and System i and do hybrid computing. You can also manage the hybrid environment through a single console, albeit a different console—the Flex System Manager—and manage this second IBM hybrid platform as a unified environment. DancingDinosaur has noted the irony of IBM having two different, incompatible hybrid systems; IBM has reassured this blogger several times that it is trying to converge the two. Whenever it happens DancingDinosaur will be the first to report it.
The zEnterprise or even PureSystems as a hybrid computing platform, however, is not the same as a hybrid data center. Apparently there is no definition of a hybrid data center despite all the talk about hybrid computing, hybrid clouds, and hybrid systems. As best DancingDinosaur can piece it together, the hybrid data center is multiplatform like the zEnterprise, but it also is multi-location, often using co-location facilities or factory-built containerized data centers (IBM calls them Portable Modular Data Centers, PMDC). More often, however, hybrid data centers are associated with cloud computing as the third of the three flavors of cloud (private, public, hybrid).
Gartner recently described some architecture options for a hybrid data center. In one case you could have a zEnterprise acting as, say, a private cloud using a co-location facility as a DMZ between the private cloud and a public cloud like Amazon. Not sure, however, you would need the DMZ if your private cloud was running on the highly secure zEnterprise but Gartner included it. Go figure.
Hybrid showed up in numerous Enterprise 2013 sessions this past October. You can catch some video highlights from it here. The conference made frequent mention of hybrid in numerous sessions, some noted in previous DancingDinosaur posts, such as Exploring the World of zEnterprise Hybrid: How Does It Work and What’s the Point? The session introduced the Unified Resource Manager and described how it would allow an IT shop to manage a collection of one or more zEnterprise nodes including any optionally attached zBX cabinets as a single logical virtualized system through a Hardware Management Console (HMC). In short, it was about providing a single point of control through which data center personnel can deploy, configure, monitor, manage and maintain the integrated System z and zBX blades based on heterogeneous architectures in a unified manner. But it wasn’t talking about the hybrid enterprise data center described in the previous paragraph.
Similarly, Application Performance Management and Capacity Planning for the IBM zEnterprise Hybrid Workload focused on extending the Unified Resource Manager to goal-oriented performance management for both traditional System z and BladeCenter applications. It was about applying WLM, RMF, and Platform Performance Management to cross-platform hybrid applications. Again, this really wasn’t about the hybrid data center described above.
BTW, plans apparently already are underway for Enterprise 2014. Looks like it will be Oct. 6-10 at the Venetian in Las Vegas. It should be quite an event given that IBM will be celebrating the 50th anniversary of the mainframe in 2014.
And there is much more on z hybrid computing and hybrid clouds. The zEnterprise has its own page on cloud computing here, and last month the zEnterprise zBC12 won CRN Tech Innovator Award for the most Innovative cloud solution. You can also click here to see how a dozen IBM customers used various IBM platforms to build hybrid clouds.
IBM has already used the zEnterprise to consolidate over 30,000 servers around the world for an 84% improvement in data center efficiency and a 50% reduction in power and cooling. This effectively freed $1 billion to spend on innovative new projects that drive business growth across the company. And IBM is about as hybrid a data center as you can find.
