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.
VMware DRS
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.
vSphere SDK package
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
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.
