Claim:
1. A method to perform distributed power management for a distributed storage system accessible by a cluster in a virtualized computing environment, the method comprising: determining, by a first host from the cluster, to initiate entry of the first host into a partial suspend mode; sending, by the first host, a request message to the cluster to take control of a storage controller of the first host; receiving, by the first host, a response message from a second host from the cluster indicating availability to take control of the storage controller; transferring, by the first host, control of the storage controller to allow the second host to control the storage controller via a network controller of the first host by pausing, by the first host, pending control instructions for the storage controller and transferring, by the first host, the pending control instructions to the second host along with an identifier of the storage controller; and entering, by the first host, into the partial suspend mode to suspend operations of one or more components of the first host while the storage controller remains controllable by the second host via the network controller.
