An example method to provide fault tolerance in a virtualized computing environment with a first host in a first fault domain and a second host in a second fault domain may include determining whether a primary virtualized computing instance and a secondary virtualized computing instance are both in the first fault domain. The secondary virtualized computing instance may be configured as a backup for the primary virtualized computing instance and supported by the first host. The method may further include: in response to determination that the primary virtualized computing instance and secondary virtualized computing instance are both in the first fault domain, selecting, from the second fault domain, the second host based on comparing a resource availability of each of a plurality of hosts that include the first host and the second host; and migrating the secondary virtualized computing instance from the first fault domain to the second fault domain.

Providing fault tolerance in a virtualized computing environment through a swapping approach

Example methods are provided to perform power management for a distributed storage system accessible by a cluster in a virtualized computing environment. The method may comprise determining that a power-off requirement is satisfied for a first host from the cluster. The power-off requirement may be satisfied based on multiple second hosts from the cluster complying with a data placement policy configured for the cluster after the first host is powered off. The method may also comprise based on the data placement policy, placing virtual machine data stored on the first host onto one or more of the multiple second hosts. The method may further comprise migrating one or more virtual machines supported by the first host to one or more of the multiple second hosts; and powering off the first host.

Power management for distributed storage systems

An example method to manage a virtual appliance in a virtualized computing environment may comprise obtaining, by a computing system, data relating to the virtual appliance that specifies a virtual machine implementing a software application. The method may also comprise configuring, by the computing system, an operational mode for the virtual machine to customize the virtual appliance for deployment. The method may further comprise deploying, by the computing system, the virtual appliance with the virtual machine operating in the operational mode.

Virtual appliance management in a virtualized computing environment based on operational modes associated with virtual appliance

An example method is described to provide fault tolerance in a virtualized computing environment with a first fault domain and a second fault domain. The method may comprise determining whether a first primary virtualized computing instance and a first secondary virtualized computing instance are both in the first fault domain. The method may comprise: in response to determination that the first primary virtualized computing instance and first secondary virtualized computing instance are both in the first fault domain, selecting a second secondary virtualized computing instance from the second fault domain; migrating the first secondary virtualized computing instance from a first host to a second host; and migrating the second secondary virtualized computing instance from the second host to the first host, thereby swapping the first secondary virtualized computing instance in the first fault domain with the second secondary virtualized computing instance in the second fault domain.

Providing fault tolerance in a virtualized computing environment through a migration approach based on resource availability

Exemplary methods, apparatuses, and systems determine that a first physical network interface controller of a first host computer has lost a client traffic network connection. At least one data compute node running on the first host computer has client traffic transmitted via the client traffic network connection. In response to the loss of the client traffic network connection, one or more host computers each having a physical network interface controller with a functioning network connection for the client traffic are identified. Further in response to the loss of the client traffic network connection, the data compute node is moved to one of the identified host computers. The first host computer utilizes a second physical network interface controller to move data compute node.
