Abstract
A data storage device is presented that includes a plurality of storage drives each comprising an associated drive Peripheral Component Interconnect Express (PCIe) interface. The data storage device also includes a control system configured to receive, over a host PCIe link, write operations for storage of data by the data storage device. The control system is configured to process the write operations against storage allocation information to apportion the data for storage among more than one of the storage drives, and transfer corresponding portions of the data to associated storage drives over corresponding drive PCIe interfaces.

A data storage device, comprising:
- a plurality of storage drives each comprising an associated drive Peripheral Component Interconnect Express (PCIe) interface;
- and
- a control system configured to:
- receive, over a host PCIe link, write operations for storage of data by the data storage device;
- process the write operations against storage allocation information to apportion the data for storage among more than one of the storage drives;
- and
- transfer corresponding portions of the data to associated storage drives over corresponding drive PCIe interfaces.
A method comprising:
- in a control system, receiving, over a host Peripheral Component Interconnect Express (PCIe) link, write operations for storage of data by a data storage device;
- in the control system, processing the write operations against storage allocation information to apportion the data for storage among more than one of a plurality of storage drives each comprising an associated drive PCIe interface;
- and
- in the control system, transferring corresponding portions of the data to associated storage drives over corresponding drive PCIe interfaces
An apparatus, comprising:
- a host Peripheral Component Interconnect Express (PCIe) link configured to receive write operations for storage of data by a data storage device;
- control circuitry configured to process the write operations against storage allocation information to apportion the data for storage among more than one of a plurality of storage drives each comprising an associated drive PCIe interface;
- and
- a drive interface configured to transfer corresponding portions of the data to associated storage drives over corresponding drive PCIe interfaces.
