MECHANISM TO DYNAMICALLY ALLOCATE PHYSICAL STORAGE DEVICE RESOURCES IN VIRTUALIZED ENVIRONMENTS

摘要

A storage device is disclosed. The storage device may include storage for data and at least one Input/Output (I/O) queue for requests from at least one virtual machine (VM) on a host device. The storage device may support an I/O queue creation command to request the allocation of an I/O queue for a VM. The I/O queue creation command may include an LBA range attribute for a range of Logical Block Addresses (LBAs) to be associated with the I/O queue. The storage device may map the range of LBAs to a range of Physical Block Addresses (PBAs) in the storage.
