fault-tolerance

Our chargeback policy for virtual machines was not clearly defined. To encourage adoption, the provisioning fee for a virtual machine was $500 regardless of system requirements. In lieu of a host being added and other considerable investments being made hardware, the chargeback policy needed to be revised. Virtual Machines within our matured Virtual Infrastructure cost more to provide but add a considerable amount of value. After a bit of reading at vmMBA and watching BM15 Managing Chargeback with VMware Infrastructure 3 from VMworld 2007 we decided to go with a tiered chargeback method....

VMware ESX has three major types of traffic: VMkernel – used for vMotion, which allows host downtime without an interruption of service Service Console – initiates vMotion, serves as the primary venue of managing Virtual Machines...
