摘要： The present disclosure describes apparatuses and methods for virtualizing isolation areas of solid-state storage media. In some aspects, a storage media accelerator determines, via a storage media interface, a geometry of solid-state storage media. The accelerator selects, based on the geometry, an area of the solid-state storage media as an isolated unit of storage. A physical address of the isolated unit of storage is then mapped to a virtual address. The accelerator exposes, via the virtual address, the isolated unit of storage through a host interface to enable host access of the isolated unit of storage. The accelerator may also remap the isolated unit of storage to other areas of the solid-state storage media without host interaction. By so doing, the accelerator may provide virtualized isolation and partitioning functionalities to a host, while efficiently handling lower-level storage media functions, such as wear leveling and load balancing, without host involvement.

摘要： A storage controller measures a RAID group (RG) operating time, which is the operating time of an RG. The storage controller then corrects the measured RG operating time, which is used to calculate the operating rate of the RG, on the basis of a correction coefficient associated with the type of the physical devices (PDEVs) constituting the RG, and on the basis of the RG backend multiplicity, which is the multiplicity of the I/O commands transmitted to the RG.

摘要： A method for managing storage and access to data files stored in a storage delivery network comprising a plurality of geographically distributed storage nodes, the method including: receiving a file request from a user, wherein the user is associated with a service level agreement (SLA) containing one or more policies governing handling of file requests from the user; determining if the SLA dictates redirecting the file request to a predetermined storage node; if the SLA dictates redirecting the file request to a predetermined storage node, redirecting the file request to the predetermined storage node; otherwise, identifying all storage nodes from the plurality of geographically distributed storage nodes that are not too busy by determining whether a number of current access requests being served by each storage node exceeds a predetermined threshold value; identifying a nearest storage node from among the not too busy storage nodes; and redirecting the user request to the nearest storage node.

摘要： An intelligent storage controller operating in conjunction with a computer running an application that uses the data managed by the intelligent storage controller, and requires data transformation operations to be performed on the data. The intelligent storage controller is adapted to directly perform the data transformation operations on the data controlled by the controller, under the direction of the computer running the application, thereby offloading this processing entirely to the intelligent storage controller. The intelligent storage controller may also provide an application programming interface for the computer running the application to use in directing commands to the intelligent storage controller. To accommodate varying workloads on the intelligent storage controller, data transformation tasks may be load balanced between the intelligent storage controller, the computer running the application, and/or other hosts.

摘要： A memory system and a method for managing the system is described. The system is configured such a plurality of system controllers, which may be RAID controllers, receive requests from the external environment and distribute the requests to a plurality of memory modules such that data may be stored in the memory modules. A global sequence number is assigned to the data of a data stripe so that the operations related to the data stripe are performed in an ordered manner so that the data remains consistent. A plurality of system controllers may comprise a domain and access a plurality of memory controllers and a plurality of domains may include at least one common memory module. A plurality of groups of controllers may communicate with a switch or with a representative controller so as to coordinate the assignment of global sequence numbers.

摘要： An I/O request directed to a portion of a storage object managed at a distributed storage service is received. A congestion control parameter value to be used to schedule a storage operation corresponding to the I/O request is determined. The congestion control parameter is based at least in part on an offset within the storage object to which the I/O request is directed. The storage operation is scheduled in accordance with the congestion control parameter at a selected physical storage device to which the portion of the storage object is mapped.

摘要： A method for load balancing includes determining a reference key within a partition key range of a partition of scalable storage, the partition key range being divided into buckets that have boundaries defining sub ranges of the partition key range. The reference key is determined based on traffic values that correspond to tracked traffic within the buckets. The traffic values are updated based on additional traffic within the buckets and the boundaries are adjusted based on the updated traffic values. A reference key speed is determined that corresponds to a rate of change of a distribution of the tracked traffic with respect to the reference key. Reference key drop-off time may be determined for reference keys. Reference keys can be utilized to determine where to split the partition and reference key speed and reference key drop-off time can be utilized to determine whether or not to split the partition.
