One embodiment provides a computing device. The computing device includes a processor; a chipset; a memory; and indirection logic. The indirection logic is to receive a host logical block address (LBA) associated with a first sector of data, map the host LBA from a host address space to a first device LBA in a device address space, the device address space related to a non-volatile memory (NVM) storage device physical memory address space, and provide the first sector of data and the first device LBA to the NVM storage device.

Host-managed non-volatile memory

In an embodiment, a storage device may include device processing logic. The device processing logic may acquire a command associated with a key-value pair (KVP). The command may be, for example, a get, set, or delete command. The KVP may include a hash value and an item. The hash value may be a key in the KVP and the item may be a value in the KVP. The device processing logic may translate the acquired command into one or more block-oriented commands which may be executed by the device processing logic to perform various operations on the storage device.

Provided are a computer program product, system, and method performing an atomic write operation across multiple storage devices. A determination is made of a plurality of storage devices on which to write data for a write operation. A tag is generated to uniquely identify the write operation. A write command is sent to each of the determined storage devices including the tag and write data to cause each of the storage devices to write the write data at the storage device. Each of the storage devices maintains a copy of a previous version of the data to be updated by the write operation. A revert command is sent with the tag to one of the storage devices to cause the storage device to restore the copy of the previous version of the write data at the storage device.

Techniques and mechanisms for managing resources of an aggregate device which spans multiple physical devices of a computer platform. In an embodiment, an aggregation device coupled to a host bus of the computer platform receives resource information generated by a pre-boot software process of the computer platform. In another embodiment, the aggregation device, based on the received resource information, represents a resource in a first input/output (I/O) device to a host operating system (OS) as residing in the aggregation device, the first I/O device coupled to the aggregation device via a host bus for exchanging communications referencing a shared address space.

Method, device and system for aggregation of shared address devices

Techniques and mechanisms for providing access to a function with an input/output (I/O) device. In an embodiment, a main memory of a computer system including the I/O device stores a function-context data structure associating a function with a context for an access to the function. The I/O device stores a configuration for the I/O device to provide the function. In another embodiment, the software process exchanges information with the function-context data structure for the access to the function. The I/O device performs a synchronization of the function-context data structure and the configuration data structure with respect to one another, wherein the function-context data structure operates as a register level interface which interfaces the I/O device and the software process with one another.

A disk array redundancy controller ensures integrity of a mirrored or RAID storage array supporting a host system and minimizes recovery time responsive to a storage volume failure by traversing caches of recently written blocks to identify partially flushed stripes of data and recovering the inconsistent stripes on each of the storage volumes based on a master copy derived from the scan of all pre-failure caches of the storage array. The storage array employs nonvolatile caches in conjunction with solid state drive (SSD) storage volumes, allowing post-failure recovery of recently written blocks. A cache depth at least sufficient to store the largest stripe, or set of blocks, from the host ensures recovery of the entire stripe from a collective scan of the caches of all storage volumes of the storage array.

Method and apparatus for synchronizing storage volumes

Techniques herein include systems and methods for driver-assisted BAR mapping that virtualize PCI functions, but without virtualizing the storage media itself. Such techniques make use of unused BARs (Base Address Registers) of a master (Operating system-facing) device to gain access to other PCIe logical instances, while still exposing only a single PCIe function (connection or channel) to system software. This technique provides a new concept of logical PCIe device instances through BAR mapping by making use of unused BARs to extend access to any number of PCIe instances or memory-mapped I/O devices behind a master device such that only a single PCIe function is exposed to system software. Embodiments can thus extend access to one or more additional storage devices through one level of BAR indirection. As a result, such techniques and embodiments enable the multiplication of storage capacity and performance through the aggregation of multiple, similar hardware components.

Driver-assisted base address register mapping

A computer system may comprise a plurality of cores that may process the tasks determined by the operating system. A network device may direct a first set of packets to a first core using a flow-spreading technique such as receive side scaling (RSS). However, the operating system may re-provision a task from the first core to a second core to balance the load, for example, on the computer system. The operating system may determine an identifier of the second core using a new data field in the socket calls to track the identifier of the second core. The operating system may provide the identifier of the second core to a network device. The network device may then direct a second set of packets to the second core using the identifier of the second core.
