摘要： Embodiments described herein provide a method for accessing a host memory through non-volatile memory over fabric bridging with direct target access. A first memory access command encapsulated in a first network packet is received at a memory interface unit and from a remote direct memory access (RDMA) interface and via a network fabric. The first memory access command is compliant with a first non-volatile memory interface protocol and the first network packet is compliant with a second non-volatile memory interface protocol. The first network packet is unwrapped to obtain the first memory access command. The first memory access command is stored in a work queue using address bits of the work queue as a pre-set index of the first memory access command. The first memory access command is sent from the work queue based on the pre-set index to activate a first target storage device.

摘要： This disclosure describes a storage aggregator controller with metadata computation control, The storage aggregator controller communicates, via a host interface, over a computer network with one or more remote hosts, and also communicates, via a storage device interface, with a plurality of local storage devices, which are separate from the remote host(s) and which have respective non-volatile memories. The storage aggregator controller manages the local storage devices for storage or retrieval of media objects. The storage aggregator controller also governs a selective computation, at aggregator control circuitry or at a storage device controller of one or more of the storage devices, of metadata that defines content characteristics of the media objects that are retrieved from the plurality of storage devices or that are received from the one or more hosts over the computer network for storage in the plurality of storage devices.

摘要： The present disclosure describes apparatuses and techniques for tunneling transaction packets. In some aspects a packet is received from a peripheral device via a first data interface of a device. The packet includes an address for resource access and an identifier that identifies the peripheral device or a function thereof. Based on this identifier, it is determined whether the peripheral device is attempting to access an internal resource of the device or a resource of a host device connected to a second data interface of the device. If the peripheral device is attempting to access the resource of the host device, the packet is routed to the host device via the second data interface without modifying the address for resource access. By so doing, the peripheral device can exchange data with the host device without using address translation.

摘要： The present disclosure describes apparatuses and methods for automatically mapping virtual functions to storage media to enable single root input output virtualization. A storage media switch manages access to virtual functions that execute behind a storage media interface managed by the switch. The switch includes a host interface through which the switch receives host commands. The switch determines virtual function identifiers associated with the host commands and automatically selects the virtual functions of the storage media based on the virtual function identifiers. The switch executes the host commands over the storage media interface using the virtual functions, and after execution, responds via the host interface to each of the host commands. By automatically mapping virtual functions in this way, the switch automatically enables single root input output virtualization of storage media, including storage media that is without native support for input output virtualization.

摘要： A NVM switch has been designed that allows multiple hosts to simultaneously and independently access a single port NVM device. While this active-active multi-host usage configuration allows for a variety of uses of lower cost single port NVM device, an issue with one of the hosts can delay or block transactions between the other host and the NVM device. The NVM switch includes logic that isolates activity of the multiple hosts despite logic of the switch being shared across the hosts. When the switch detects an issue with one host ("error host"), the switch clears the in-flight commands of the error host and flushes data of the error host. Likewise, the NVM switch ensure proper communication of error reporting from attached NVM devices to the multiple hosts.

摘要： A non-volatile memory express (NVMe) switch is located in between a host and storage. A first storage access command is received from a host via a peripheral computer interface express (PCIe) interface to access the storage. The first storage access command conforms to NVMe and the storage comprises two or more solid-state drives (SSDs). A respective second storage access command is sent to the two or more SSDs based on the first storage access command. A respective completion is received from each of the two or more SSDs based on the respective second storage access command. A completion is sent to the host via the PCIe interface based on the received completions from each of the two or more SSDs.

摘要： The present disclosure describes apparatuses and methods for virtualizing isolation areas of solid-state storage media. In some aspects, a storage media accelerator determines, via a storage media interface, a geometry of solid-state storage media. The accelerator selects, based on the geometry, an area of the solid-state storage media as an isolated unit of storage. A physical address of the isolated unit of storage is then mapped to a virtual address. The accelerator exposes, via the virtual address, the isolated unit of storage through a host interface to enable host access of the isolated unit of storage. The accelerator may also remap the isolated unit of storage to other areas of the solid-state storage media without host interaction. By so doing, the accelerator may provide virtualized isolation and partitioning functionalities to a host, while efficiently handling lower-level storage media functions, such as wear leveling and load balancing, without host involvement.
