virtualization and high performance compared to older technologies. Married to a zEnterprise server, these technologies allow the end user to have the ultimate in performance and energy efficiency. The z196 is a high-performance, highly virtualized, energy-efficient platform that will be the core of many next-generation green and virtual data centers. Many end users will purchase new storage as well. Newer models of DASD arrays with relatively new technologies such as extended address volumes (EAVs), Hy per Parallel Access Volumes (HyperPAVs), support for System zHigh Performance FICON (zHPF), and solid state drives (SSD) should be considered for implementation with a z196. All of these technologies enable either better performance or reduced energy consumption, and better virtualization technologies lead to smaller footprints.

What About Connectivity?
What’s often the “forgotten stepchild” is the connectivity (i.e., the data-center network and the FICON or ESCON* storage network, which will be attached to that shiny new mainframe and storage). The z196 is sold with FICON Express 8 or ESCON channels for storage connectivity and Open System Adapter-Express (OSA-Express 3) 10 Gbps channels for IP connectivity.

On the storage side, many end users still have a few isolated devices requiring ESCON connectivity, so they need to buy ESCON channels for their z196 and have a plan in place to move to FICON for those devices. Ideally, end users who purchase a new z196 and storage, and have ESCON as their primary storage connectivity, will migrate to FICON. Many end users are also running older-generation FICON directors, which have performed well, been extremely reliable and done the job as intended. However, they’re essentially outdated technology in terms of internal architecture, and this impacts performance. They’re also not as dense in terms of ports and floor space, and they are less energy efficient. The same is true of 90 percent of the IP connectivity devices attached to mainframes today, and their technology is even older. An analogy that describes this scenario is the purchase of a highperformance car. Many years ago I owned a Chevy Cavalier. When it was time for an upgrade, I bought a certified pre-owned 1998 BMW 328i. It had much better acceleration, cornering, etc. The BMW needed tires. Did I take the Cavalier tires and use them on the BMW (saving me some upfront costs and sacrificing performance)? No, I bought tires designed for the 328i. So why would anyone buy a z196 with FICON Express 8 chan-

RED HAT

ON THE MAINFRAME
THE REASONS ARE COMPELLING
When deployed on IBM System z, Red Hat® Enterprise Linux® provides flexibility, performance, and scalability for server consolidation or mainframe reliability. Built on more than a decade of industry collaboration, Red Hat Enterprise Linux for IBM System z brings Linux applications to the mainframe and delivers efficient management for your Linux workloads.

Virtualization for virtualization’s sake
and implementing countless virtual SANs when you could just use zoning merely adds management complexity.
