Partitioning a flash memory data storage device

A method of partitioning a data storage device, the method comprising:

• receiving, via an interface operably coupling a host with the data storage device, information indicating a number of a plurality of flash memory chips in the data storage device, a first portion of the plurality of flash memory chips being implemented in a first memory channel and a second portion of the plurality of flash memory chips being implemented in a second memory channel;
• defining, by the host, a first partition of the data storage device, the first partition including a first subset of the plurality of flash memory chips that includes one or more memory chips of the first memory channel and one or more memory chips of the second memory channel;
• and
• defining, by the host, a second partition of the data storage device, the second partition including a second subset of the plurality of flash memory chips that does not include any flash memory chips of the first subset, a boundary between the first partition and the second partition being defined by the first subset of memory chips and the second subset of memory chip.

An apparatus comprising:

• a data storage device including a plurality of memory chips, a first portion of the plurality of memory chips being implemented in a first memory channel and a second portion of the plurality of memory chips being implemented in a second memory channel;
• an interface operably coupled with the data storage device;
• and
• a host operably coupled with the data storage device via the interface, the host including:
• a configuration detection engine configured to communicate with the data storage device, via the interface, to detect a number of the plurality of memory chips in the data storage device;
• and
• a partition engine configured to define a first partition of the data storage device, the first partition including a first subset of the plurality of memory chips and to define a second partition of the data storage device, the second partition including a second subset of the plurality of memory chips,
• the first subset including one or more memory chips of the first memory channel and one or more memory chips of the second memory channel;
• the first subset not including any memory chips of the second subset;
• and
• a boundary between the first partition and second partition being defined by the first subset of memory chips and the second subset of memory chips.

A method of partitioning a data storage device, wherein the device includes a plurality of memory chips, the method comprising:

• reading, by a host via a PCIe interface operably coupling the host with the data storage device, a physical configuration of the data storage device, the physical configuration including a number of the plurality of memory chips in the data storage device, a first portion of the plurality of memory chips being implemented in a first memory channel and a second portion of the plurality of memory chips being implemented in a second memory channel;
• reading, but the host via the PCIe interface, a partitioning scheme for the data storage device;
• defining, via by the host, a first partition of the data storage device, the first partition including a first subset of the plurality of memory chips;
• allocating, by the host, a logical to physical memory map for the first partition;
• defining, by the host, a second partition of the data storage device, the second partition including a second subset of the plurality of memory chips;
• and
• allocating, by the host, a logical to physical memory map for the second partition,
• the first subset including one or more memory chips of the first memory channel and one or more memory chips of the second memory channel;
• the first subset not including any memory chips of the second subset;
• and
• a boundary between the first partition and second partition is defined by the first subset of memory chips and the second subset of memory chips.
