The Outside View of VMs Layer
This layer represents the pSeries server's view of the resource allocation and usage levels of each of the LPARs hosted on it. Using the information reported by this test, administrators can:
- Know the quantity of resources each LPAR is configured with;
- Determine which of LPARs are taking up more resources (CPU, memory, network, or disk) than the others. This information can help with load balancing or capacity planning. For example, if one of the VMs is receiving a very high rate of requests compared to the others, this VM may be a candidate for migration to another pSeries server, so as to minimize the impact it has on the other guests on the current pSeries server.
- Track the overall status of the LPARs - how many are registered, which ones are powered on, and at what times, etc.
