WHAT IS IBM’S ENTERPRISE WORKLOAD MANAGER AND IBM’S SASP PROTOCOL?
IBM’s Enterprise Workload Manager Enterprise Workload Manager (EWLM) is a product in the IBM Virtualization Engine Suite for Servers. EWLM dynamically monitor server resources and provides input on load balancing decisions. The Workload Manager takes into account a server’s CPU, storage capacity, and network traffic in any final weighting decisions. The Workload Manager uses an implementation of the SASP protocol to perform this task. IBM’s WLM software allows you to specify end-to-end performance goals for distributed requests. WLM runs on an entity responsible for reporting or managing a group of members. This entity is known as the Domain Manager (DM). DM recommends a weight for each application/server in the group. This weight recommendation is based on the business importance, topology and ability of the system to meet its business goals. This recommended weight helps the application switch make intelligent server load balancing decisions.
