Abstract
A storage pool is shared by multiple host computers in a cluster that runs virtual machines. In one embodiment, one of the host computers in the cluster is designated to include a storage pool manager. Each host computer in the cluster monitors its storage consumption and notifies the storage pool manager of its storage consumption. Thus, storage space in the storage pool can be dynamically allocated on demand.
