Report showing the load graph, includes Memory, CPU, N-1 and N-2. Would assume that would show potential performance if you lost one server or two servers out of cluster? But N-1 shows higher perf load than N-2? So not sure if reading this correctly?

Hi andrea.meyer,

Hopefully the following will help with your questions.

This report presents statistics for the virtual enterprise as a whole, and a summary for each cluster and group. Values are provided showing month over month with growth. A reserve capacity indicator is supplied for clusters, indicating the performance tolerance of running with 1 and or 2 fewer hosts.

Therefore the n-1 and n-2 show the effect of losing 1 (n-1) or 2 (n-2) hosts in the cluster, and whether the remaining hosts can run the workload effectively and at what resource consumption.

In addition, N represents the number of hosts in the cluster -

N-1 is literally (N-1)/N. In this example since N=2., then (N-1)/N = 50%.

* This means losing a host bring you down to 50% host availability.

* The smaller the cluster the bigger the impact of losing a host.

• N-2 is literally (N-2)/N. So in this case 0% meaning you have no hosts available.
