Debugging Performance Problems in FICON SANs
Project and Program: Information Management
, SHARE Atlanta 2016
Slow FICON devices ? Bad Response times during a certain workload ? Batch workload not completing during the defined window ?
The session will discuss how to determine if this is or is not related to your SAN and if it is, how to narrow down what is the bottleneck or failing/problem component. We will first discuss terminology so that you can communicate effectively with your SAN admins. Then we will highlight the performance troubleshooting tools that are available. Finally, we will look at several example issues and look thru the relevant data gathered from the host and the FICON directors to determine where the problem resides and then discuss how to fix each of the issues.-Mike Blair-Cisco Systems, Inc.
