Project and Program: MVS, MVS Performance

Tags: Proceedings, 2012, SHARE in Atlanta 2012

Yes- I/O does still matters. During this session Peter Enrico will present the approach he uses when performing a DASD I/O subsystem performance analysis. During this session Peter will discuss how to look at DASD I/O performance from at DASDplex level, physical control unit level, LCU level, and logical volume level. Peter will also discuss how to identify the problem logical volumes that are impacting the DASD I/O subsystem the most. Peter Enrico, Enterprise Performance Strategies Inc,
