MULTI-DESTINATION PROBABILISTIC DATA REPLICATION
20230033066 · 2023-02-02 ·

Disclosed embodiments provide techniques for multi-destination probabilistic data replication. Data transfer occurs over multiple time intervals. A data image to be transferred is divided into chunks. A manifest is created that lists each chunk and specifies an order, such that the data image can be reconstructed at its destination. The manifest is sent to the destination. The chunks may be sent to the destination, or to an aggregator site that then forwards the chunks to the destination. The chunks are reassembled at the destination based on information in the manifest. A probabilistic function is used to select an aggregator site based on an efficacy. The efficacy is based on a reward function that is computed for destinations for each time interval. A data transfer policy is periodically updated with a new efficacy value which is used for adjustment of the probabilistic function.

System and method for failure handling for virtual volumes across multiple storage systems

A method, computer program product, and computing system for generating a pair of protocol endpoints within each storage system of a pair of storage systems. One protocol endpoint of the pair of protocol endpoints may be dedicated to each storage system of the pair of storage systems. One or more IO requests may be processed between one or more hosts and one or more virtual volumes within the pair of storage systems via the pair of protocol endpoints.

HOT DATA MANAGEMENT IN A DATA STORAGE SYSTEM

A data storage system may store a first data block having a first data configuration generated by a host in a non-volatile memory that is connected to a data module. A data strategy may be generated with the data module in response to the storage of data with the data strategy consisting of at least one trigger associated with identifying the first data block as hot. The first data block can be replicated to a different memory location with a second data configuration as directed by the data strategy with the first data configuration being different than the second data configuration.

SHARED STORAGE MODEL FOR HIGH AVAILABILITY WITHIN CLOUD ENVIRONMENTS
20230087493 · 2023-03-23 ·

Techniques are provided for a high availability solution (e.g., a network attached storage (NAS) solution) with address preservation during switchover. A first virtual machine is deployed into a first domain and a second virtual machine is deployed into a second domain of a computing environment. The first and second virtual machines are configured as a node pair for providing clients with access to data stored within an aggregate comprising one or more storage structures within shared storage of the computing environment. A load balancer is utilized to manage logical interfaces used by clients to access the virtual machines. During switchover, the load balancer preserves an IP address used to mount and access a data share of the aggregate used by a client.

The application provides a method for data reading and writing processing, data center, disaster recovery system and storage medium. The method includes receiving, by a first data center, a data reading request including a first user identification; determining, in response to the data reading request, whether a writing user identification set stored in the first data center includes the first user identification, the writing user identification set including user identifications corresponding to data writing requests; and under a condition that the writing user identification set includes the first user identification, forwarding the data reading request to a second data center, to read, in the second data center, data to be read as indicated by the data reading request, the second data center being configured to receive and process a data writing request sent by a user terminal or forwarded by the first data center.

MANAGEMENT AND ORCHESTRATION OF MICROSERVICES

Techniques are provided for microservices management and orchestration. A chart package is selectively retrieved from a chart repository based upon the chart package corresponding to a set of services to host within a cluster and dependencies amongst the set of services. A set of container images may be retrieved from a container repository based upon the set of container images corresponding to the set of services. A cluster may be created within a computing environment. The set of services may be deployed as resources of the computing environment within the cluster and the dependencies may be configured using the chart package and the set of container images.

AUTOMATIC RECOVERY OF LOCKING FILESYSTEM SHARED BETWEEN VIRTUAL TAPE LIBRARY NODES
20220350711 · 2022-11-03 · ·

A virtual tape library system includes multiple copies of a LockFS that are mounted on all nodes. One of the LockFSs is designated as the active copy. A primary node manages recovery when a secondary node signals loss of connectivity with the active copy by posting a sync request file to at least one of the LockFSs. The primary node posts status request files to the LockFSs and the secondary nodes respond by writing status to the status request files. A LockFS that is reachable by all nodes is selected as the new active LockFS. Switchover is accomplished by the primary node posting a disable request file to the selected LockFS and waiting for all secondary nodes to acknowledge by writing to the disable request file. The primary node then posts an activate request file to the selected LockFS and waits for all secondary nodes to acknowledge by writing to the activate request file.
