A queue-based non-volatile memory (NVM) hardware assist card, information handling system, and method are disclosed herein. An embodiment of the queue-based NVM hardware assist card includes a plurality of downstream ports configured to be connected to a corresponding plurality of actual queue-based NVM storage devices, a plurality of upstream ports configured to appear as a plurality of apparent queue-based NVM storage devices, and a distinct upstream port of a different type than the plurality of upstream ports, the distinct upstream port for interacting with a host processor to receive a consolidated processing NVM command from and to return a consolidated processing NVM command completion indication, the queue-based NVM hardware assist card configured to aggregate multiple of the NVM command completion messages received via respective ones of the plurality of downstream ports from respective ones of the plurality of actual queue-based NVM storage devices and to generate the consolidated processing NVM command completion indication.

Method and apparatus for non-volatile memory array improvement using a command aggregation circuit

In accordance with embodiments of the present disclosure, an information handling system may include a processor and a plurality of physical storage resources communicatively coupled to the processor via a bus, the plurality of physical storage resources configured to, in order to facilitate booting from a virtual logical unit spanning the plurality of physical storage resources: (i) after enumeration of the plurality of physical storage resources, construct the virtual logical unit based on metadata of the plurality of physical storage resources; and (ii) prior to construction of the virtual logical unit, respond to input/output commands from an operating system of the information handling system with data associated with a dummy logical unit or with an indication that the dummy logical unit is busy.

Systems and methods for booting from virtual volume spanned across unknown number of storage devices by constructing a virtual logical unit based on metadata of the storage resources and by responding to I/O commands with data associated with a dummy logical unit

A remote secure drive access method includes receiving a first message from a second server. The message may be received by a baseboard management controller (BMC) of the first server via a PCIe switch from a second server coupled to the first server via an ExpEther connection. A payload of the message may include identification information identifying the second server. The first server may send an endpoint discover message and receive endpoint device information indicative of peripheral and/or endpoint resources of the second server, including a storage controller associated with a secure drive. Secure drive key information may be obtained from the payload of the first virtual message and sent to the second server to access the secure drive. The exchanged messages may comprise proprietary PCIe transaction layer packets enclosed within an Ethernet packet that includes an ExpEther frame within an Ethernet frame.

Remote secure drive discovery and access

An information handling system includes a first storage controller coupled to a first storage device, a second storage controller coupled to a second storage device where the first storage device and the second storage device comprise a virtual disk and a processor to initiate a first discovery of the first storage device, initiate a first discovery of the virtual disk on the first storage controller, complete the discovery of the first storage device, initiate a first discovery of the second storage device, initiate a second discovery of the virtual disk on the second storage controller, determine that a first timeout for the first discovery of the virtual disk on the first storage controller will expire prior to completing the first discovery of the second storage device, and initiate a second discovery of the first storage device in response to determining that the timeout will expire.
