Capacity Management of Virtual Environment

The present invention comprises a process to calculate the capacity available in a VMware Virtual Infrastructure cluster using the reporting capabilities found in VirtualCenter and builds in a method to reserve capacity for new guests. This process requires the reports on a cluster using VMware's VirtualCenter (VC). This offers an IT department the ability to establish thresholds and properly plan for adding resources (e.g. memory, storage, CPU, or additional hosts) to an existing cluster.

This process is novel because it capitalizes on the customer-specific work intake process to produce usable capacity metrics at a cluster level while reserving capacity for planned guests regardless of the underlying server infrastructure. There were no other methods found during the novelty research process that provides the customer the ability to track and reserve work intake specific to their specific needs.

To start the process, create a spreadsheet using an application that can open Microsoft Excel documents. This spreadsheet will be referred to as the Cluster Capacity spreadsheet (CCS).

In a tab of the CCS, identify each ESX host and corresponding speed of processor core in GHz, total number of cores, and total memory. It is best to put one host's information in a row with other hosts in subsequent rows to aid in totaling cluster resources. On the same tab, list the shared storage by LUN and size in the same fashion. Refer to this tab as the Summary tab.

On another tab, list out the resources required by new or planned guests commonly identified by a work intake process. The resources should be listed by total number of CPU, memory, and disk. These resources can be rolled up by project (e.g. application specific, customer-specific or general growth guests. Refer to this tab as the Reservation tab.

On another tab, copy and paste the Memory Usage and CPU Usage values collected from VC. It might be helpful to include the Time Stamp with these values as a point of reference so duplicate values are not captured. Refer to this tab as the Roll-up tab.

To gather these values, access VC using the VirtualInfrastructure Client (VIC); highlight the cluster, from the File menu select Reports and Performa...
