Storage

“What goes around comes around” is an old saying that’s especially true for information technology, particularly for data center management philosophies. We’ve gone from centralized to distributed and back again. As far as storage connectivity goes, we’ve gone from direct-attached to networked, and, in the mainframe space, we have a recurring question, “Do I need FICON switching technology, or should I go direct-attached?” With up to 288 FICON Express8 channels supported on a System z196, why not just direct-attach the control units?…

Archive and long-term data storage requirements are growing at a record pace. As a result, many businesses are wrestling with deciding whether to build their archive strategy on disk, tape, or a combination. According to IDC's June 2011 Digital Universe Study, the world's digital data is more than doubling every two years with approximately 1.8 zettabytes to be created and copied or replicated in 2011 and up to 7.9 zettabytes by 2015. In addition, individuals now generate up to 75 percent of all digital information. According to the study, the magnitude of 1.8 zettabytes of data is equivalent to:…

Many believe virtualization is about consolidation; it’s really about emulation and abstraction, which enables agility, flexibility, masking of underlying complexity, and consolidation. We’ve been in the virtualization efficiency era, where the focus and value proposition are around saving, reducing, and avoiding. We’re now entering the effectiveness era, where the focus and value proposition expand to enablement and productivity…

Reputation-damaging corporate scandals, such as the Enron case in 2001, have highlighted the need for stronger compliance and regulations for publicly listed companies. Compliance regulations—such as Sarbanes-Oxley, the Health Information Portability and Accountability Act (HIPAA), and the Gramm-Leach-Bliley Act—were created to ensure that financial, customer, and patient information is safeguarded and available for long periods of time…

Continuous availability and disaster recovery solutions aren’t just for disasters. System and application outages can be due to server or disk storage hardware failure, improper maintenance procedures, local building issues, human error, and, yes, disasters. IBM System z and IBM Geographically Dispersed Parallel Sysplex (GDPS) can help protect you from data loss and help ensure application availability from planned and unplanned outages…

End-to-end application management and visibility are toward the top of the list for nearly every CIO. Why is this such a pressing problem, and why has IT been unable to solve it?

One major challenge is achieving end-to-end visibility of an application that provides a single point of control and a unified view of the application, regardless of the tools that IT staff employ to check or resolve application performance. The need—and the potential—for complete application visibility is even more keenly felt with the introduction of zEnterprise-class computing, which provides firmware-level integration across the IBM Systems p, x (x86), and z platforms through the IBM zEnterprise Unified Resource Manager (zManager)…

The mainframe has most certainly defied the predictions of industry pundits; in fact, in the past 10 years, most mainframe shops have grown their MIPS capacity by 15 to 25 percent per year. This  increase reflects both more work and new kinds of work. The “new workloads” may be z/OS transactions arriving from outboard distributed servers or UNIX applications now running under Linux on System z on Integrated Facility for Linux (IFL) processors. The result is a significantly larger mainframe presence than the pundits anticipated.
