A server rack may include a chassis management controller (CMC), a server having a baseboard management controller (BMC) configured to communicate with the CMC, a controller stored in the server rack for interoperating with a cache memory, and a set of solid state devices (SSDs) providing data storage. The CMC may amalgamate data storage provided by the SSDs and partition the amalgamated data storage into an individual logical cache for use with or by the BMC or controller.

In accordance with embodiments of the present disclosure, a system may include a first storage controller for managing a Redundant Array of Independent Disks (RAID) comprising a plurality of disk drives and a second storage controller for managing at least one disk drive other than the plurality of disk drives. The first storage controller may be configured to: (i) in response to the RAID having a degraded state and the first storage controller not having an available hot spare disk drive local to the first storage controller, communicate a request for a hot spare disk drive of another storage controller; (ii) receive a response to the request identifying a disk drive of the second storage controller as an alternative available hot spare disk drive; and (iii) communicate with the second storage controller to use the alternative available hot spare disk drive to rebuild the RAID.

An information handling system includes a method for detecting a predictive failure indication for a predictive failure indicated physical disk of a disk group, determining an amount of used storage capacity of a lowest capacity physical disk of the disk group, and comparing a replacement storage capacity of a replacement physical disk to the used storage capacity. When the replacement storage capacity is greater than or equal to the used storage capacity even if the replacement storage capacity is less than a lowest storage capacity of the lowest capacity physical disk of the disk group, replacing the predictive failure indicated physical disk with the replacement physical disk.

A GUID partition table (GPT) based Hidden Data Store (HDS) system includes first computing systems that include networked storage devices and that are coupled to a second computing system through a network. The second computing system include local storage devices that provide a GPT having a GPT entry that identifies local HDS elements that provides an HDS and that are included on the local storage devices, and networked HDS elements that provide the HDS and that are included on the networked storage devices. The second computing system also includes an HDS engine that receives the GPT entry and authorization credentials, determines that the authorization credentials allow access to the HDS and, in response, provides access to the local HDS elements that are included on the local storage devices, and provide access to the networked HDS elements that are included on the networked storage devices.

A disclosed method for implementing a RAID-6 virtual disk includes performing data storing operations in response to receiving write data. The data storing operations include, in at least one embodiment: storing a block of the write data in D data stripes distributed across D of N storage devices, where D and N are integers greater than 0 and N is greater than D. The storage devices may correspond to disk drives, but may correspond to other types of storage devices as well

RAID-6 for storage system employing a hot spare drive

A method provides rebuilding data in a hot spare storage device when multiple storage devices fail in a storage system. The method includes a storage controller determining if a first storage device storing first data has failed within a first group of storage devices. In response to the first storage device failing, the first data is rebuilt in the hot spare storage device from a copy of the first data stored in a first mirrored storage device of the first group of storage devices. In response to a second storage device failing, third data is generated by performing a first exclusive or (XOR) operation with the first data stored on the hot spare storage device and a copy of the second data stored in a second mirrored storage device of the second group of storage devices. The third data is rebuilt in the hot spare storage device. The method recovers original data and prevents complete failure of a virtual disk.

In accordance with these and other embodiments of the present disclosure, a system may include a processor and a program of executable instructions embodied in non-transitory computer-readable media accessible to the processor. The program of executable instructions may be configured to, when read and executed by the processor, monitor for a failure of a storage resource in a pool of storage resources configured as a plurality of optimally-redundant virtual storage resources, determine if a virtual storage resource comprising the storage resource is able to rebuild the virtual storage resource, and, in response to determining that the virtual storage resource comprising the storage resource is unable to rebuild the virtual storage resource, migrate each of one or more virtual machines mapped to the virtual storage resource to another virtual storage resource in an optimal redundancy state.

An information handling system includes a method, information handling system, and redundant array of independent disks (RAID) controller. When a write request is received, data are written to a non-volatile memory write cache. When a read request is received, it is determined whether the data are available from a volatile memory read cache. When the data are available from the volatile memory read cache, the data are obtained from the volatile memory read cache and provided in response to the read request. When the data are not available from the volatile memory read cache, the data are obtained from a RAID virtual disk coupled to the RAID controller, the data are stored in the volatile memory read cache, and the data are provided in response to the read request.
