Abstract: To increase the availability of a non-volatile cache for use by workloads, the non-volatile cache is dynamically assigned to workloads. The non-volatile cache assigned to a workload can be reduced or increased on demand. A cache space manager ensures that the physical non-volatile cache is available to be assigned prior to assigning. A workload analyzer recognizes a sequential or random workload and requests to reduce the cache space assigned for the sequential or random workload. The workload analyzer recognizes a locality workload, waits until cache space is available in the non-volatile cache and requests an increase of cache space for the locality workload.

Abstract: Systems, apparatuses, and methods provide for a memory controller to manage a tiered memory including a zoned namespace drive memory capacity tier. For example, a memory controller includes logic to translate a standard zoned namespace drive address associated with a user write to a tiered memory address write. The tiered memory address write is associated with the tiered memory including the persistent memory cache tier and the zoned namespace drive memory capacity tier. A plurality of tiered memory address writes are collected, where the plurality of tiered memory address writes include the tiered memory address write and other tiered memory address writes in the persistent memory cache tier. The collected plurality of tiered memory address writes are transferred from the persistent memory cache tier to the zoned namespace drive memory capacity tier, via an append-type zoned namespace drive write command.

Abstract: An electronic processing system may include a device driver to provide redundant array of independent disks (RAID) functionality. The device driver may include a detector to detect whether operation as a RAID controller device is established. The device driver may also include a controller to establish operation of a device as the RAID controller device when no device has established operation as the RAID controller device. The device driver may further include a publisher to publish a block device before exposure as usable storage, wherein publication of the block device is to be understood only by the RAID controller device.
