This video demonstrates reporting into the interrelationships between several key metrics when group capping (LPAR based capping / soft capping) is in effect. These metrics include 4 hour rolling average, cap values, interval CPU consumption, MSUs available relative to the cap, and percentage of the interval WLM capping was in effect.
Reports demonstrated include:
- Available Capacity for LPAR Groups (MSU)
- Capacity Group MSU
- Captured CP Use by WLM Importance Level (MSU)
- Capacity Limit (Soft Cap) (MSU)
- LPAR Capping and Usage (MSU)
Conserving MSUs – Déjà vu All Over Again
In the past, you probably only focused on MSU usage during your peak 4HRA. Now, thanks to IBM's Software Consumption, paying more attention to MSUs at non-peak times literally “pays” in terms of saving real money.
Mainframe Cost Savings Part 3: Address Space Opportunities
This final blog in the mainframe cost reduction series will cover potential CPU reduction opportunities that produce benefits applicable to a specific address space or application.
Mainframe Cost Savings Part 2: 4HRA, zIIP Overflow, XCF, and Db2 Memory
This blog covers several CPU reduction areas, including, moving work outside the monthly peak R4HA interval, reducing zIIP overflow, reducing XCF volumes, and leveraging Db2 memory to reduce I/Os.
