    Abstract: Provided are an apparatus, computer program product, system, and method for managing multiple regions of a non-volatile memory device. A first group of logical bands is assigned to a first memory region in which metadata will be stored and a second group of logical bands is assigned to a second memory region to which host data is written, wherein the second group of logical bands is larger than the first group of logical bands. Physical bands are mapped to the first number of logical bands and the second number of logical bands. Indication is returned to the host system of the first and second groups of logical bands assigned to the first and second memory regions, respectively. The host system directs requests for metadata to logical addresses in the first group of logical bands and directs request for file data to logical addresses in the second group of logical bands

    Abstract: A mass storage device controller is described. The controller is to process first and second read requests received at an I/O interface of a mass storage device. The first read request includes a first logical block address. The first read request is to provide a first block stored within non volatile storage media of the mass storage device at the I/O interface. The first block is identified by the first logical block address. The second read request includes a second logical block address and specifies one or more bytes within a second block identified by the second block address and stored within the non volatile storage media. The second read request is to provide the one or more bytes at the I/O interface.

    Abstract: An operating system of a computational device manages access of a plurality of applications to a solid state drive. Separate bands are maintained in the solid state drive for storing writes of at least two different applications of the plurality of applications. Additionally, in other embodiments, a virtual machine manager of a computational device manages access of a plurality of virtual machines to a solid state drive. Separate bands are maintained in the solid state drive for storing writes of at least two different virtual machines of the plurality of virtual machines.

    Abstract: On-SSD-copy using Copy-On-Write (COW) techniques track indirection updates to the copied data without duplicating the data. In one example, a method involves receiving a copy command to copy data from a source LBA to a destination LBA. An entry in a logical-to-physical (L2P) table corresponding to the destination LBA is updated to refer to the same physical address as the source LBA's entry in the L2P table. Flags in the L2P table are updated to indicate that more than one LBA refers to the same physical address. After updating the L2P table and before copying the data, a token is stored to the storage device. After storing the token, but before copying the data, an acknowledgement can be sent to the host to indicate the copy command is complete. A subsequent write to either the source or destination LBAs trigger a copy of the data.
