BLOCK STORAGE VIRTUALIZATION MANAGER

Described are techniques for implementing a block storage virtualization (BSV) manager. The techniques including a method comprising associating a Block Storage Virtualization (BSV) manager with a virtual machine (VM) having virtually provisioned block storage resources. The method further comprises aggregating, by the BSV manager, the virtually provisioned block storage resources into a virtual address space having a maximum capacity and an allocated capacity, wherein the allocated capacity is less than the maximum capacity. The method further comprises determining, by the BSV manager, that free space in the allocated capacity is less than a provisioning threshold. The method further comprises, in response to determining that the free space in the allocated capacity is less than the provisioning threshold, procuring, by the BSV manager, a predetermined amount of additional block storage resources for the VM.
