Mainframe Solutions

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 (268 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

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
