Finding Root Cause of Performance Issues in IBM SVC Environments
Just a few bad LUNs in an SVC all flash storage pool have a profound effect on the I/O experience of the entire IBM Spectrum Virtualize (SVC) environment.
Getting the Most out of zEDC Hardware Compression
z Enterprise Data Compression (zEDC) is an emerging z/OS technology that must be properly managed to get the most out of its benefits
Game Changer for z/OS Transaction Reporting
Obtaining key metrics for CICS, DB2, and IMS transactions have historically required processing massive volumes of SMF 110 records.
How to Prevent an “Epic” EMR System Outage
Application slowdowns in Electronic Medical Record (EMR) Systems or Electronic Health Record (EHR) Systems can have serious consequences.
The Circle of (Storage) Life
New storage technologies are quickly maturing and replacing legacy platforms. But will they be mature enough to meet your high availability, high performance IT infrastructure needs?
Compressing Wisely with IBM Spectrum Virtualize
Data compression in an IBM SVC Spectrum Virtualize environment may help regain capacity, but hidden performance problems can occur if compressible workloads are not first identified.
What Good is a zEDC Card?
IntelliMagic Vision for z/OS is a wonderful tool to review zEDC activity and there are likely two reports of great interest, The PCIe Card Utilization, and Compression Ratios.
How’s Your Flash Doing?
Since most storage management algorithms optimize their enterprise storage automatically, you may not have the time or tools to quantify how your Flash is performing.
Flash Performance in High-End Storage
As the price per gigabyte of flash storage is rapidly decreasing, experts predict that flash will soon be the dominant medium in high-end storage.
