STATISTICAL POWER HANDLING IN A SCALABLE STORAGE SYSTEM

摘要

Systems, methods, apparatuses, and software for data storage systems are provided herein. In one example, a data storage assembly is provided that includes a plurality of storage drives each comprising a PCIe host interface and solid state storage media. The data storage assembly includes a PCIe switch circuit coupled to the PCIe host interfaces of the storage drives and configured to receive storage operations issued by one or more host systems over a shared PCIe interface and transfer the storage operations for delivery to the storage drives over selected ones of the PCIe host interfaces. The data storage assembly includes a control processor configured to monitor usage statistics of the storage drives, and power control circuitry configured to selectively remove the power from ones of the storage drives based at least on the usage statistics of the storage drives.

1. A data storage assembly, comprising:
a plurality of storage drives each comprising a Peripheral Component Interconnect Express (PCIe) host interface and solid state storage media, with each of the plurality of storage drives configured to store and retrieve data responsive to storage operations received over the associated PCIe host interface; a PCIe switch circuit coupled to the PCIe host interfaces of the plurality of storage drives and configured to receive the storage operations issued by one or more host systems over a shared PCIe interface and transfer the storage operations for delivery to the plurality of storage drives over selected ones of the PCIe host interfaces; a control processor configured to monitor usage statistics of the plurality of storage drives; and power control circuitry configured to provide power to the plurality of storage drives and selectively remove the power from ones of the plurality of storage drives based at least on the usage statistics of the plurality of storage drives.
