Abstract: The present disclosure provides systems and methods for utilizing a blockchain network configured to receive threat intelligence requests and validate or invalidate such threat intelligence requests based on a consensus response from a series of nodes on the blockchain network. According to the present disclosure, the method includes receiving a threat intelligence request at one or more smart contracts of a blockchain network. The method includes broadcasting, via the one or more smart contracts, the threat intelligence request to one or more oracles. The one or more oracles may broadcast the threat intelligence request to one or more nodes. The one or more nodes may gather threat intelligence data based on the threat intelligence request. The one or more oracles may determine if consensus is reached by the one or more nodes. If consensus is reached, then a threat entry may be submitted to the one or more smart contracts.

Abstract: A method, computer program product, and computer system for full allocation volume to deduplication volume migration in a storage system. The method includes moving a physical allocation of stored data associated with a full allocation volume into a virtual address range in a deduplication domain and setting up the deduplication metadata to be a passthrough. The method then performs a background deduplication process on the virtual address range once populated with the physical allocations using a drive query hash interface to perform hash calculations on physical drives at which the data is stored.

Abstract: Method and system for partitioning of deduplication domains in storage systems. The method includes constructing a data structure having multiple nodes representing data chunks and edges between the nodes representing a weighting of deduplication references between the data chunks, and performing clustering of the nodes of the data structure to split the nodes into clusters of tightly related nodes based on the weightings of the edges. The data chunks represented by a cluster of nodes are migrated to a deduplication domain to restrict deduplication to between only the data chunks in the deduplication domain.

Abstract: A data recovery method recovers corrupted data after a disaster event in a storage facility operating with deduplication in which copies of data are maintained between volumes through a copy services relationship. The deduplication operates with referencing domains, each having a source grain containing a reference pointing to a location where data is stored and referrers pointing to the source. The data recovery method identifies any source that is pointing to data which is corrupt and then establishes whether a copy services relationship exists between the referencing domain of the source with corrupted data and another referencing domain, in which case the other referencing domain will have a copy of the corrupted data. Provided that the copy is valid, it is written across to replace the corrupted data. The method allows corrupted source data to be recovered without having to perform a full resync or restore.

Abstract: Concepts for remote storage of data are presented. Once such concept is a system comprising: a primary storage controller; and a secondary storage controller of a remote data storage system. The primary storage controller is configured to determine a service characteristic of data storage to or data retrieval from the remote data storage system and to communicate service performance signals to the secondary storage controller based on the determined service characteristic. The secondary storage controller is configured to receive service performance signals from the primary storage controller, to compare the received service performance signals with a service requirement so as to determine a service comparison result, and to control data storage to or data retrieval from the remote data storage system based on the service comparison result.

Abstract: Method and system are provided for managing capacity in a storage system using copy services. The method is a computer-implemented method that predicts an imminent event due to a constrained resource and identifies one or more copy service relationship that will mitigate the imminent event. The method orchestrates a partial or full invalidation of a copy service relationship to reclaim some of the constrained resource to prevent the imminent event, including updating the copy service relationship metadata to indicate the invalidation.

Abstract: The invention features methods, devices, and kits for predicting the responsiveness of a cancer patient (e.g., a breast cancer patient, such as a grade 1, 2, or 3 breast cancer patient) to anthracycline treatment by determining the expression levels of four chromosomal instability (CIN) genes including HDGF, KIAA0286, RFC4, and MSH6, collectively referred to as CIN4. Patients that have a low CIN4 score benefit from anthracycline treatment compared patients with a high CIN4 score.

Abstract: Methods, systems, devices and computer implemented methods of prognosing or classifying patients using a biomarker comprising a plurality of subnetwork modules are disclosed. In some embodiments, the method comprises determining an activity of a plurality of genes in a test sample of a patient, wherein the plurality of genes are associated with the plurality of subnetwork modules. An expression profile is constructed using the activity of the plurality of genes. The dysregulation of each of the plurality of subnetwork modules is determined by calculating a score proportional to a degree of dysregulation in each of the plurality of subnetwork modules from the expression profile. The patient is prognosed or classified by inputting each dysregulation score into a model for predicting patient outcomes for patients having a disease, and inputting a clinical indicator of the patient into the model, to obtain a risk associated with the disease.

Abstract: Input/output (I/O) I/O target selection is achieved within a data storage system having clustered nodes of initiators, I/O targets, and grouped storage logical units. A state definition component defines access states for each combination of one or more combinations of a node, an I/O target, and a storage logical unit. A profiler component produces an access state profile for each I/O target. A rank criteria compiler compiles rank criteria as a basis for best-fit identification of I/O targets for a logical unit (LU) group. A best-fit identifier is responsive to the profile component and the rank criteria compiler and identifies a ranked best-fit order of I/O targets for an LU group. A target selector selects an I/O target for an LU group from the ranked best-fit order.
