EMC World 2015: Brocade, EMC and Mainframe

by Dr.Steve.Guendert on ‎05-01-2015 08:16 AM (1,171 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 (1,188 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.

Load Sharing and Load Balancing for FICON

by Howard.Johnson on ‎09-22-2010 08:31 AM (436 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
