5 Reasons Why All-Flash Arrays Won’t Magically Solve All Your Problems
It may feel like all-flash systems will solve all your performance issues, but the complexity of the entire infrastructure ensures that there are still plenty of problems to run into.
Mainframe Capacity “Through the Looking Glass”
When processor cache is optimized, mainframe processors remain productive by actively executing instructions rather than unproductively burning cycles.
Achieving Significant Software Cost Reduction on the IBM z13
While most mainframe shops have explored how to reduce mainframe software costs, at IntelliMagic we are finding significant latent savings opportunities still exist at even the best run sites.
This is alarming
To avoid getting overloaded with meaningless alarms, it is important to implement best practices, the first being a software solution that is intelligent.
IBM z/OS’s Microscope – GTF
With a GTF I/O summary trace, what appears innocuous at the RMF level can have some surprising characteristics when put under the GTF microscope.
Shelfware, IT’s version of Home Exercise Equipment
Unused software, or shelfware, is a pervasive problem in enterprise IT as it doesn't take other factors like personnel, processes, and skills into account.
How are my Disk Storage Systems doin’?
Disk storage systems provide hundreds of performance-related metrics but in order to identify which of the metrics are key, one first needs to know what exactly the metric represents.
Pend Time Haiku
The I/O infrastructure for IBM z Systems is second to none in the enterprise space, including the detailed metrics delineating where time is spent in I/O processing.
The Attack of the Disk Clones
While most mainframe shops have explored how to reduce mainframe software costs, we are finding significant latent savings opportunities still exist at even the best run sites.
Beneficial Use of GDPS Copy Once Facility (Experimental Evidence)
A Copy Once Facility is not expensive to implement or maintain and can save up to 50% of the bandwidth that would be required if it wasn’t available.
Performance Modeling for Disk Storage Systems
This blog demonstrates how computer system performance modeling is done, specifically for disk storage systems.
HDS Pools Hit the Target in RMF for Hitachi Dynamic Tiering
HDS created their Hitachi Dynamic Provisioning (HDP) pools which greatly increase your ability to get insight in the back-end and autotiering workload for the VSP.
