A Solid History of Mainframe Innovation Continues Through Storage and Networking Technologies

An Interview With Lloyd Carney, CEO of Brocade

By Denny Yost

FICON, its relationship with IBM and growth opportunities in the mainframe market. Carney: It parallels the history with mainframe technology I just mentioned. We have a close working partnership with Enterprise Executive: Lloyd, please tell us a little about IBM System z in Poughkeepsie and IBM’s storage team in Brocade. Tucson. We hold multiple technical-interlock meetings with IBM each year. During these interlocks, we exchange Lloyd Carney: Brocade is a company forged out of the data product roadmaps and development ideas. We have a Joint center that has delivered networking technologies in the Development Agreement (JDA) with IBM that has led to most mission-critical IT environments throughout our some innovative technologies for our mutual customers,

It allows our mutual generation technologies, including the Brocade Gen 5 Fibre customers to reach unlimited distances between their data Channel/FICON solutions, that will provide them the most center sites and achieve the recovery time objectives of one state-of-the-art capabilities and features. minute or less, previously only available in a metro area solution.

Carney: The IBM mainframe has always been at the forefront in the evolution of IT trends. Let’s look at EE: What key technological advancements has Brocade virtualization for a moment. IBM pioneered the concept of introduced recently for the mainframe market? virtual storage on S/370 in the early ’70s. The famous August 1972 IBM System/370 Advanced Function announcement Carney: We’ve introduced several enhancements in introduced four new IBM mainframe operating systems: our Fibre Channel operating system known as FOS, or DOS/VS (DOS with virtual storage), OS/VS1 (OS/MFT with Fabric OS. There are several more currently undergoing virtual storage), OS/VS2 (OS/MVT with virtual storage, qualification at IBM Poughkeepsie with our latest operating which would grow into SVS and MVS) and VM/370. system release (FOS 7.1). For example, we’ve added some Multiple Virtual Storage (MVS) is still with us in the form of enhanced diagnostics features to FICON CUP that will z/OS. The concept of virtual machines has been around for allow for integration of our FICON directors with the IBM more than 40 years now, thanks to the IBM mainframe. As z/OS Health Check functionality. We made some significant far as cloud computing goes, thanks to that pioneering work enhancements to our FOS Extended Fabrics feature that will in virtualization, the IBM mainframe and today’s System z simplify buffer credit management for applications such as were clouds before cloud was a word. Few people realize that multisite Disaster Recovery (DR). We’ve also recently the first Storage Area Network (SAN) was ESCON. And as introduced some exciting, new technologies that will allow far as SDN goes, I think the modern System z led the way customers to more efficiently utilize their cross-site with the z/OS Communications Server. bandwidth, as bandwidth between sites is the most expensive cost in any DR architecture. Anything Brocade EE: What is Brocade’s current R&D strategy for the can do to enable our customers to improve performance mainframe market? and reduce costs over those DR networks is a win-win for the customer and for Brocade. Carney: Brocade is a customer-centric company. We take very seriously our customers’ input and suggestions for EE: How much longer will Brocade continue to invest in the feature enhancements and new capabilities. Many of these mainframe market? recommendations still come from our mainframe/FICON customers.
