In some examples, a computing system receives an indication of an increased workload portion to be added to a workload of a storage system, the workload comprising buckets of operations of different characteristics. The computing system computes, based on quantities of operations of the different characteristics in the workload, factor values that indicate distribution of operations of the increased workload portion to the buckets of operations of the different characteristics, and distributes, according to the factor values, the operations of the increased workload portion into the buckets of operations of the different characteristics.

A method for determining a storage location includes one or more processing modules of one or more computing devices of a storage network (SN) receiving a data object to store in a storage network (SN) and determining whether the data object is subject to a legal restriction, where a data object is subject to a legal restriction based on the data object requiring storage in a jurisdiction that subjects the data object to a retention policy. The method continues by determining one or more attributes of a first storage location of a plurality of storage locations and based on a determination that the data object is subject to a legal restriction and at least one attribute of the one or more attributes of the first storage location, transmitting a write threshold number of write requests to a plurality of SUs at the first storage location.

The present disclosure provides a method for information storage and a system thereof, which adapts to a data storage system. A monitoring unit is configured to detecting and monitoring operations of a storage node in the data storage system to generate corresponding one and more monitoring data. A recording processor is configured to receiving the one or the plurality of monitoring data, and rendering one or a plurality of logs according to the difference of content of the one or the plurality of monitoring data. The adjustment mechanism is performed according to the stored logs, thereby the amount of large data generated during monitoring is effectively reduced.

One embodiment provides a computer implemented method of estimating replication completion time. The method includes creating a historical dataset of prior replication data; determining a set of replication parameters to consider; inputting the historical dataset and the set of replication parameters to a replication completion time estimator module; generating a replication completion time prediction based on the historical dataset and the set of replication parameters; and generating a confidence prediction corresponding to the replication completion time prediction.

A technique manages data within a storage array. The technique involves forming a hybrid tier within the storage array, the hybrid tier including SSD storage and HDD storage. The technique further involves, after the hybrid tier is formed, providing hybrid ubers (or Redundant Array of Independent Disks (RAID) extents) from the SSD storage and the HDD storage of the hybrid tier. The technique further involves, after the hybrid ubers are provided, accessing the hybrid ubers to perform data storage operations.

The present invention provides a control method of a flash memory controller, wherein the flash memory controller is configured to access a flash memory module, and the control method includes the steps of: receiving a settling command from a host device to configure a portion space of the flash memory module as a zoned namespace; receiving a write command from the host device to write data corresponding a first zone into a plurality of blocks of the flash memory module, wherein an access mode chose by the flash memory controller is determined based on a size of each zone and a size of each block.

The present invention provides systems and methods for data storage. A hierarchical storage management architecture is presented to facilitate data management. The disclosed system provides methods for evaluating the state of stored data relative to enterprise needs by using weighted parameters that may be user defined. Also disclosed are systems and methods evaluating costing and risk management associated with stored data.

According to the embodiments, an external storage device switches to an interface controller for supporting only a read operation of nonvolatile memory when a shift condition for shifting to a read only mode is met. A host device switches to an interface driver for supporting only the read operation of the nonvolatile memory when determining to recognize as read only memory based on information acquired from the external storage device.

The storage system is capable of creating one or more virtual storage subsystems to which virtual resources having logically divided a processing capacity of the physical resources are allocated, and upon creating a virtual volume for receiving I/O requests from the host within the virtual storage subsystem, the virtual storage subsystem allocates the virtual resource to the virtual volume, and when an I/O request to the virtual volume is received from the host, performs processing related to the I/O request using the virtual resource having been allocated. According further to the storage system, after allocating the virtual resource to the virtual volume, the storage system raises a utilization rate of the virtual resource allocated to the virtual volume in a stepwise manner.

A computer includes an SMS module that communicates with a management server apparatus via a network, a display that displays predetermined information, and a CPU that controls an operation of the display. When the SMS module receives a control command from the management server apparatus via the network, the CPU executes processing corresponding to the control command. Furthermore, the CPU transmits a notification signal including information, which indicates a state of execution of the control program, to the management server apparatus via the network.

Furthermore, the CPU displays, on the display, a state indicator including information which indicates a state of execution of the control program when the notification signal cannot be transmitted to the management server apparatus via the network.
