Abstract: An apparatus includes a plurality of drives configured as a redundant array of independent disks (RAID) and drive array controller logic to: calculate a first partial parity log (PPL) value for a first write operation that targets a first active stripe of the plurality of drives; store the first PPL value in a first pre-allocated portion of the plurality of drives that depends on a first number associated with the first active stripe; calculate a second PPL value for a second write operation that targets a second active stripe of the plurality of drives; and store the second PPL value in a second pre-allocated portion of the plurality of drives that depends on a second number associated with the second active stripe.

Abstract: An embodiment of a semiconductor apparatus for use with redundant storage may include technology to cache all data for a write request for at least two member persistent storage drives in a persistent cache with a write access latency at least as low as a lowest write access latency of the at least two member persistent storage drives, write the data for the write request to one member persistent storage drive of the at least two member persistent storage drives, and indicate that the write request is complete after the data for the write request is redundantly stored in the persistent cache and the one member persistent storage drive. Other embodiments are disclosed and claimed.

Abstract: Techniques to facilitate an out-of-band (OOB) management in a virtualization environment include examples of assigning an endpoint identifier to a domain mapped to physical memory addresses of one or more storage devices coupled with a computing platform. The domain may enable software or a device driver executed by a virtual machine (VM) to access, manage or control at least a portion of the one or more storage devices. Examples also include receiving or forwarding messages through an OOB communication link coupled with the computing platform to a management entity to facilitate OOB management of the software or the device driver executed by the VM.

Abstract: Embodiments of the present disclosure may relate to a data storage apparatus that may include a redundancy logic to determine recovery data based on data in a storage region buffer; and a storage region controller to schedule a first set of non-volatile memory (NVM) dies in a first solid state drive (SSD) to be in a non-deterministic (ND) state or a deterministic (D) state, schedule a second set of NVM dies in a second SSD to be in a ND state or a D state, issue a first write command to write the data to the first set of NVM dies when the first set of NVM dies are in the ND state, and issue a second write command to write the recovery data to the second of NVM dies when the second set of NVM dies are in the ND state. Other embodiments may be described and/or claimed.

Abstract: An apparatus may include a storage driver, the storage driver coupled to a processor, to a non-volatile random access memory (NVRAM), and to a redundant array of independent disks (RAID), the storage driver to: receive a memory write request from the processor for data stored in the NVRAM; calculate parity data from the data and store the parity data in the NVRAM; and write the data and the parity data to the RAID without prior storage of the data and the parity data to a journaling drive. In embodiments, the storage driver may be integrated with the RAID. In embodiments, the storage driver may write the data and the parity data to the RAID by direct memory access (DMA) of the NVRAM.

Abstract: Examples relate to a computer system, a computer system host, a first storage device, a second storage device, controllers, methods, apparatuses and computer programs. The computer system includes a first storage device and a second storage device. A storage region is distributed across the first storage device and the second storage device. The computer system further includes a computer system host. The computer system further includes a communication infrastructure configured to connect the first storage device, the second storage device and the computer system host. The computer system host is configured to transmit a request related to the storage region to the first storage device via the communication infrastructure. The first storage device is configured to issue a further request to the second storage device via the communication infrastructure to execute the request.
