EMC World 2015: Brocade, EMC and Mainframe

by Dr.Steve.Guendert on ‎05-01-2015 08:16 AM (5,477 Views)

Brocade and EMC have a great history of working together to provide world class FICON attached storage solutions to IBM z Systems end users all over the globe. While that history is important, the future looks even brighter! I will be delivering a presentation as part of the mainframe track at EMC World 2015 and wanted to take this opportunity to share some of the things I will be discussing in the presentation.


The Holy Grail of Extension for IBM System z: Introducing the IBM System Storage SAN42B-R

by Dr.Steve.Guendert ‎12-01-2014 02:34 PM - edited ‎12-02-2014 06:50 AM (8,900 Views)

The IBM System Storage SAN42B-R (aka Brocade 7840 Extension Switch) is a true game changer for business continuity in IBM System z environments. It is a quantum leap forward over all existing extension products in the market today in terms of performance, advanced features, management, scalability, and availability.


Cut-through the complexity of Storage Networking Management!


Complexity in the data center not only complicates your day-to-day tasks it also exacerbates the problem of maintaining high availability, impairs your ability to provide acceptable performance and efficiency, often increases your overall data center costs and too often inhibits your ability to scale and grow to meet internal demands.


Expensive, home grown expertise is often utilized in data centers to coax as much benefit and value as possible, using a maze of tools and techniques, from your growing FC fabrics and I/O interconnects. However the value actually achieved from these efforts is always variable depending upon each SAN administrator’s capabilities. And troubleshooting actual problems that occur within a SAN infrastructure can be very frustrating and time consuming.


Brocade has been delivering a Gen5 switch portfolio solution that has evolved and now offers you a smarter and more consistent answer for managing all of your storage networking fabrics. Brocade Network Advisor contains several new Fabric Vision technologies that will cut through SAN management complexity while improving your level of confidence and satisfaction in your Brocade I/O infrastructure. Monitoring and Alerting Policy Suite (MAPS) along with Flow Vision, two of those Fabric Vision technologies, deploys breakthrough capabilities that dramatically simplify open systems and mainframe SAN administration, improves the availability and performance of fibre channel SANs, reduces operational costs and can be deployed in a matter of just a few minutes.


Mainframes and Social Media

Over the weekend I realized that I have violated one of the cardinal rules of blogging.  It has been 2 months since our last blog post. That is an eternity in the era of social media where we're bombarded with tweets and Facebook updates con


I just returned to the office after two weeks in China.  I was in Shanghai and Beijing to work with my good friend, IBmer Dennis Ng.  Dennis and I, as mentioned in


I have been visiting with customers in Asia and Europe recently who are in the midst of doing infrastructure and/or storage refresh in their data centers. Typically the results from upgrading your fibre channel infrastructure is good news fo


In chapter two of this new blog series of mine I am going to tackle what I consider to be a data center FOLLIE.

Cables (multi-mode or single mode) and Optics (SFPs) go together, hand in glove. Short wave SFPs are always attached


In chapter one of this new blog series of mine I am going to discuss a FICON FABLE first.

As you know, FICON Channel Features provide the System z with Fibre Channel port connectivity for FICON storage and FCP storage. Each of t


The Performance Information Gap Paradox

Happy February??  I thought perhaps I missed two months,  I never would have thought it would be 60 degrees (Fahrenheit) in Columbus, OH on February 1st. Anyway....

I hope everyone had a wonderful holiday season, a Merry Christmas, and a Happy New Year!  This is our first blog post of 2012, and as 2012 starts we're working on several interesting things primarily focused on perfor


The 16Gbps FICON DCX 8510: It's a big deal

by Dr.Steve.Guendert on ‎11-29-2011 10:19 PM (2,781 Views)

On 29 November 2011 IBM announced support for FICON on the Brocade DCX 8510 family of 16 Gbps fibre channel directors (IBM SAN 768B-2 and SAN 384B-2).  IBM announced general availability (GA) for 2 December 2011.  The detailed IBM announceme


Mainframes have been evolving for four plus decades and with the IBM zEnterprise System, have re-established themselves as core processing facilities that contain


Happy 47th Birthday IBM Mainframe

by Dr.Steve.Guendert on ‎04-01-2011 01:10 PM (4,514 Views)

April 7th is next week and to mainframers that is a special day.  April 7th marks the 47th birthday of the IBM Mainframe. Some may argue that IBM had other "mainframes" prior to this date, such as the IBM 701 Defense Calculator


Greetings and Happy 2011.  Its a great time to be a mainframer.  IBM's new model z196 is enjoying tremendous success around the world.  IBM mainframe technology appears to be experiencing a


Load Sharing and Load Balancing for FICON

by Howard.Johnson on ‎09-22-2010 08:31 AM (2,599 Views)

Load sharing and load balancing are two functions that are often confused when discussing SAN performance.  When balancing loads, the idea is to balance the “potential” flows over the available paths.  When sharing loads, the idea is to dist


The IBM zEnterprise (z196) and SHARE Boston 2010

by Dr.Steve.Guendert on ‎08-10-2010 05:38 AM (1,738 Views)

July 22, 2010 was a significant day in the history of mainframe computing.  The new IBM zEnterprise is not merely a new mainframe.  It represents the culmination in what may very well be the shift back to the centralized model of computing.


OK, yes I know.  The title for my post sounds like a sequel for a “B” movie.   Well, in a way it is kind of a sequel.  Allow me to explain.

Let’s take a brief trip down (mainframe I/O) memory lane.  Its early 2004 and IBM has an
