Chapter 1 vSphere Components VMware DRS vSphere SDK package VMware Data Recovery When you enable the cluster for HA, you specify the number of hosts you would like to be able to recover. If you specify the number of host failures allowed as 1, HA maintains enough capacity across the cluster to tolerate the failure of one host. All running virtual machines on that host can be restarted on remaining hosts. By default, you cannot power on a virtual machine if doing so violates required failover capacity. See the VMware Availability Guide for more information. A feature that helps improve resource allocation and power consumption across all hosts and resource pools. VMware DRS collects resource usage information for all hosts and virtual machines in the cluster and gives recommendations (or migrates virtual machines) in one of two situations: n Initial placement - When you first power on a virtual machine in the cluster, DRS either places the virtual machine or makes a recommendation. n Load balancing - DRS tries to improve resource utilization across the cluster by performing automatic migrations of virtual machines (VMotion) or by providing a recommendation for virtual machine migrations. VMware DRS includes distributed power management (DPM) capabilities. When DPM is enabled, the system compares cluster- and host-level capacity to the demands of virtual machines running in the cluster. Based on the results of the comparison, DPM recommends (or automatically implements) actions that can reduce the power consumption of the cluster. APIs for managing virtual infrastructure and documentation describing those APIs. The SDK also includes the vCenter Server Web Service interface, Web Services Description Language (WSDL), and example files. This is available through an external link. You can download the SDK package from the VMware APIs and SDKs Documentation page on the VMware Web site. VMware Data Recovery is a disk-based backup and recovery solution that provides complete data protection for virtual machines. VMware Data Recovery is fully integrated with VMware vCenter Server to enable centralized and efficient management of backup jobs and includes data de-duplication to minimize disk usage.
