High performance parity-based Redundant Array of Independent Disks (RAID) on Zoned Namespaces Solid State Drives (SSD)s with support for high queue depth write Input Output (IO) and Zone Append command is provided in a host system. The host system includes a stripe mapping table to store mappings between parity strips and data strips in stripes on the RAID member SSDs. The host system also includes a Logical to Physical (L2P) table to store data block addresses returned by the Zone Append command.

Method and apparatus to improve performance of a redundant array of independent disks that includes zoned namespaces drives

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.

Techniques to facilitate out of band management in a virtualization environment

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.

Low latency mirrored raid with persistent cache

According to various aspects, a storage system is provided, the storage system including a multiplicity of storage devices, and one or more processors configured to store user data on the multiplicity of storage devices, the stored user data being distributed among the multiplicity of storage devices together with redundancy data and with log data; generate a classification associated with the redundancy data and the log data to provide classified redundancy data and classified log data, and write the classified redundancy data and the classified log data on the respective storage device of the multiplicity of storage devices according to the classification associated therewith.

Storage system, computing system, and methods thereof

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.
