An information processing apparatus includes a memory; and a processor coupled to the memory and the processor configured to: generate first information including configuration information and/or interface information of a first program of an old version based on code of the first program of the old version, and generate second information including configuration information and/or interface information of the first program of a new version based on code of the first program of the new version; and generate information on compatibility between the first program of the old version and the first program of the new version based on whether there is a difference between the first information and the second information generated by the processor.

A configuration for a component of a primary node is synchronized with a configuration for a component of a partner node in a different cluster by replicating the primary node configuration with the partner node. A baseline configuration replication comprises a snapshot of a component configuration on the primary. The baseline configuration can be generated by traversing through the configuration objects, capturing their attributes and encapsulating them in a package. The baseline package can then be transferred to the partner node. The configuration objects can be applied on the partner node in the order in which they were captured on the primary node. Attributes of the configuration objects are identified that are to be transformed. Values for the identified attributes are transformed from a name space in the primary node to a name space in the partner node.

Staging data on a storage element integrating fast durable storage and bulk durable storage, including: receiving, at a storage element integrating fast durable storage and bulk durable storage, a data storage operation from a host computer; storing data corresponding to the data storage operation within fast durable storage in accordance with a first data resiliency technique; and responsive to detecting a condition for transferring data between fast durable storage and bulk durable storage, transferring the data from fast durable storage to bulk durable storage in accordance with a second data resiliency technique.

A storage system has zones in solid-state storage memory, with power loss protection. The system identifies portions of data for processes that utilize power loss protection. The system determines to activate or deactivate power loss protection for the portions of data for the processes. The system tracks activation and deactivation of power loss protection in zones in the solid-state storage memory, in accordance with the portions of data having power loss protection activated or deactivated.

A method for protecting data in a storage system is disclosed. In one embodiment, such a method includes detecting, by a first hardware management console, first battery-on status associated with a first uninterruptible power supply. The method further detects, by a second hardware management console, second battery-on status associated with a second uninterruptible power supply. The method communicates, from the first hardware management console to the second hardware management console, the first battery-on status. The method then triggers, by the second hardware management console, a dump of modified data from memory to more persistent storage upon detecting both the first battery-on status and the second battery-on status. A corresponding system and computer program product are also disclosed.

Assessing protection for storage resources, including: identifying a set of active data protection features for one or more storage resources; generating a data protection assessment based on the set of active data protection features; and reporting the data protection assessment.

There are provided an information processing system that operates virtual machines and storage controllers on a processor, and an information processing method executed by the information processing system. A storage controller group capable of taking over processing between the storage controllers arranged in different nodes is provided. The virtual machine is movable between the different nodes by deploy. The virtual machine and the storage controller that processes data input and output by the virtual machine are arranged in the same node. A combination of the virtual machines that cannot be arranged in the same node is defined by a restriction. A management unit arranges one of the virtual machines that cannot be arranged in the same node in the node in which the storage controller included in the storage controller group to which the storage controller used by the other virtual machine belongs is not arranged.

Methods and systems for a networked storage system are provided. One method includes: receiving, by a first storage node, a request to modify data stored using a logical storage object presented by the first storage node, the first storage node communicating with a second storage node configured as a failover partner of the first storage node; transmitting, by the first storage node, an invalidation request to the second storage node to invalidate an entry in a storage location cache of the second storage node, the entry indicating a storage location where data is stored by the first storage node, before modification; and responding, by the first storage node, to the request after modifying the data and upon receiving a response from the second storage node indicating successful invalidation of the entry.

Generating datasets using approximate baselines including receiving, by a source storage system, an instruction to create, on a target storage system, a current snapshot for a source dataset stored on the source storage system, wherein no snapshots for the source dataset exist on the target storage system; selecting, as a baseline dataset, a similar dataset from a plurality of datasets on the source storage system with an existing snapshot on the target storage system, wherein the similar dataset comprises at least a portion of the source dataset; instructing the target storage system to generate a baseline snapshot for the source dataset using a copy of the existing snapshot of the baseline dataset; and transferring, from the source storage system to the target storage system, only a difference between the baseline dataset and the source dataset.

Various embodiments are directed to techniques for coordinating at least partially parallel performance and cancellation of data access commands between nodes of a storage cluster system. An apparatus may include a processor component of a first node coupled to a first storage device storing client device data; an access component to perform replica data access commands of replica command sets on the client device data, each replica command set assigned a set ID; a communications component to analyze a set ID included in a network packet to determine whether a portion of a replica command set in the network packet is redundant, and to reassemble the replica command set from the portion based if the portion is not redundant; and an ordering component to provide the communications component with set IDs of replica command sets of which the access component has fully performed the set of replica data access commands.
