An aspect of the invention relates to a method of managing jobs in a information system (SI) on which a plurality of jobs run, the information system (SI) comprising a plurality of computer nodes (NDi) and at least a first storage tier (NS1) associated with a first performance tier and a second storage tier (NS2) associated with a second performance tier lower than the first performance tier, each job being associated with a priority level determined from a set of parameters comprising the node or nodes (NDi) on which the job is to be executed, the method comprising a step of scheduling the jobs as a function of the priority level associated with each job; the set of parameters used for determining the priority level also comprising a first parameter relating to the storage tier to be used for the data necessary for the execution of the job in question and a second parameter relating to the position of the data necessary for the execution of the job (TAi) in question.

Maintaining a synchronous replication relationship between two or more storage systems, including: receiving, by at least one of a plurality of storage systems across which a dataset will be synchronously replicated, timing information for at least one of the plurality of storage systems; and establishing, based on the timing information, a synchronous replication lease describing a period of time during which the synchronous replication relationship is valid, wherein a request to modify the dataset may only be acknowledged after a copy of the dataset has been modified on each of the storage systems.

According to one embodiment, a memory device includes a first nonvolatile memory die, a second nonvolatile memory die, a controller, and a first temperature sensor and a second temperature sensor incorporated respectively in the first nonvolatile memory die and the second nonvolatile memory die. The controller reads temperatures measured by the first and second temperature sensors, from the first and second nonvolatile memory dies. When at least one of the temperatures read from the first and second nonvolatile memory dies is equal to or higher than a threshold temperature, the controller reduces a frequency of issue of commands to the first and second nonvolatile memory dies or a seed of access to the first and second nonvolatile memory dies.

Methods and systems for a networked storage system are provided. One method includes assigning a quality of service (QOS) parameter for a storage volume of a networked storage environment having a first storage node and a second storage node, where the QOS parameter is defined by a throughput value that defines a maximum data transfer rate and a number of input/output (I/O) operations executed within a time period (IOPS); distributing the QOS parameter between the first storage node and the second storage node; determining that throughput credit is available for processing an I/O request for using the storage volume; determining that IOPS credit is available for processing the request by the first storage node; and processing the I/O request when both the throughput credit and the IOPS credit is available.

The present disclosure discloses a control device of data storage system, including a host interface, a peer interface, a storage unit interface, a processor and a local data management module. The host interface is connected and communicated with a storage server for data interaction with the storage server. The peer interface is configured for data communication connection with a storage unit of an adjacent control device in the data storage system. The storage unit interface is configured to connect a storage unit. The local data management module is configured for local data management of the data in the storage unit according to the data management instruction via the processor. The host interface is configured to send result data of local data management to the storage server.

A method for execution by a computing device of a dispersed storage network includes obtaining resource information for a subset of storage units of a storage unit pool. W available storage units of the storage unit pool are identified in response to receiving a store data request. W choose S combinations of selecting S number of storage units of the W available storage units are identified. A plurality of rating levels is calculated based on the resource information, where each of the plurality of rating levels are assigned to a corresponding combination of the W choose S combinations. One combination of the W choose S combinations is selected based on the plurality of rating levels. Storage of data of the store data request is facilitated utilizing the S number of storage units of the selected one combination.

The present disclosure involves systems and methods for managing a trie routing table for a networking device of a communication or computer network. In one implementation, the networking device may utilize a dynamic algorithm for associating hashing functions with pivot tiles of the routing table to improve hash utilization and avoid hash collisions. Further, route prefixes may be relocated from pivot tiles in an attempt to free the tiles for reallocation to other prefix base width or may be relocated to other possible pivot tiles or to a general storage space when a hash collision is detected. This provides for even distribution of pivots within tiles which have base widths in range of a pivot route. The above implementations may occur together or separately to improve the operation of the networking device and provide faster route lookup.

Commands in a command queue are received and scheduled. For each of the commands, scheduling includes determining an age of a command based on an entrance time of the command in the command queue. When the age of the command satisfies a first threshold, marking all other commands in the command queue as not issuable when the command is a deterministic command, and marking all other commands in the command queue as not issuable when the command is a non-deterministic command and the intermediate command queue is not empty. Scheduling the command further includes determining whether the command is a read command and marking the command as not issuable when the command is a non-deterministic read command and the intermediate command queue is empty.

An instruction to generate a cloud instantiation of a secondary storage system is provided. One or more secondary storage clusters are virtually rebuilt in the cloud instantiation of the secondary storage system. A new cloud instance of a user virtual machine is deployed based on at least a portion of data stored in the one or more rebuilt secondary storage clusters of the cloud instantiation of the secondary storage system. A version of at least the portion of the data of the one or more rebuilt secondary storage clusters is provided to a cloud deployment server.

According to one embodiment, a memory system is connectable to a host including a first volatile memory and includes a non-volatile memory and a controller. The controller may use a first area of the first volatile memory as a temporary storage memory of data stored in the non-volatile memory and controls the non-volatile memory. The controller generates a first parity by using first data stored in the non-volatile memory and a key value to store the first data and the generated first parity in the first area. In the case of reading the first data stored in the first area, the controller reads the first data and the first parity to verify the read first data using the read first parity and the key value.
