In some examples, a system detects recovery, from an unavailable state, of a communication link between a first storage system that includes a first storage volume and a second storage system that includes a second storage volume that is to be a synchronized version of the first storage volume, where while the communication link is in the unavailable state the second storage volume is in an offline state and the first storage volume is in an online state. In response to detecting the recovery of the communication link, the system sends a first tracking metadata for the first storage volume from the first storage system to the second storage system, and in response to receipt of the first tracking metadata at the second storage system that maintains a second tracking metadata for the second storage volume, the system transitions the second storage volume from the offline state to a controlled online state, and initiates a synchronization process to synchronize the second storage volume with the first storage volume.

Example implementations can involve a system, which can involve a server configured to distribute role decision condition expressions created based on user input to one or more storage devices; and the one or more storage devices, which can involve a processor, configured to, for receipt of a request, determine user identification information, request source environment information and requested contents from the request; determine a role from the role decision condition expressions based on the user identification information and request source environment information; and determine whether or not the request can be executed based on the role.

A network storage volume stores first entries in a first-mode storage bucket and a second entries in a second-mode storage bucket. The first-mode storage bucket has first bucket metadata, and the second-mode storage bucket has second bucket metadata. A computer-implemented method includes comparing a utilized capacity of the network storage volume to a target capacity information of the network storage volume to obtain a comparison result. Based on the comparison result, at least one bucket is selected to be purged from the buckets of the network storage volume based at least in part on bucket metadata of the buckets. The method further includes causing a purge of the at least one selected bucket from the network storage volume.

Source database precommitted transactions are resolved in a target database of a database replication system when selected source database precommitted transactions are subsequently aborted in the source database.

Operation of a non-volatile memory (NVM) storage module may comprise receiving a plurality of commands as associated with a plurality of priority-based queues from a host-memory. A received command is evaluated in accordance with a priority associated with the queue storing the command and a size of the command. The evaluated command is split into a plurality of sub-commands, each of the sub-commands having a size determined in accordance with the evaluation. A predetermined number of hardware resources are allocated for each of the evaluated command based on at least the size of each of the sub-commands to thereby enable a processing of the evaluated command based on the allocated resources. Quality of service (QoS) for the evaluated-command may thus be augmented.

A computer storage device having a host interface, a controller, non-volatile storage media, and firmware. The firmware instructs the controller to: limit a crypto key to be used in data access requests made in a first namespace allocated on the non-volatile storage media of the computer storage device; store data in the first namespace in an encrypted form that is to be decrypted using the crypto key; free a portion of the non-volatile storage media from the first namespace, the portion storing the data; and make the portion of the non-volatile storage media available in a second namespace without erasing the data stored in the portion of the non-volatile storage media.

A system and method for logging state data from a power system control device on a computer system is disclosed. The computer system includes a power system supplying power to the computer system. The power system has a power-up sequence having a plurality of stages. The power system control device is coupled to the power system. The power system control device includes a finite state machine circuit having states corresponding to the stages of the power-up sequence. The control device also has a write controller, a storage buffer, and a communication interface. The write controller writes the state of the finite state machine circuit in the storage buffer. An external controller is coupled to the communication interface and is operable to read the stored state data.

Embodiments for a method performing data migration such as backups and restores in a network by identifying characteristics of data in a data saveset to separate the data into defined types based on respective characteristics, assigning a data label to each defined type by receiving user selection or automatically merging or selecting a priority label, from among many labels associated with a file, defining migration rules for each data label, discovering assigned labels during a migration operation; and applying respective migration rules to labeled data in the data saveset. The migration rules can dictate storage location, access rights, replication periods, retention periods, and similar parameters.

Described are methods, systems and computer readable media for dynamic updating of query result displays.

A computer-implemented method includes receiving a request to provision a set of storage volumes for a server cluster, wherein the request includes an identifier for the server cluster and generating a provisioning work ticket for each storage volume in the set of storage volumes, each provisioning work ticket including the identifier for the server cluster. The provisioning work tickets are provided to a message broker. Multiple volume provisioning instances are executed such that at least two of the volume provisioning instances operate in parallel with each other and such that each volume provisioning instance receives a respective provisioning work ticket from the message broker and attempts to provision a respective storage volume of the set of storage volumes for the server cluster in response to receiving the volume provisioning work ticket.
