摘要： 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

摘要： 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.

摘要： Systems and methods for accessing data stored in a remote target using a Baseboard Management Controller (BMC) and independently of the status of the remote target's Operating System (OS). In some embodiments, a BMC of an Information Handling System (IHS) may have program instructions stored thereon that, upon execution, cause the IHS to: communicate with another BMC of another IHS over a network; and access a storage device of the other IHS through the other BMC via the network while the other IHS operates without any OS. In other embodiments, a method may include determining, by a first IHS, that a second IHS is operating without any OS; and sending, by a first BMC within the first IHS to a second BMC within the second IHS, an access request directed to a virtual drive of the second IHS.

摘要： 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.

摘要： 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.

摘要： 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.
