Abstract: Method and system are provided for recycling container storage objects at a storage controller. The method includes receiving a create operation of a new container by an orchestrator, including information indicating a purpose of the container, and associating a label with the new container, with the label indicating the orchestrator-defined information. The method includes checking labels of soft-deleted container objects for a suitable match with the label of the new container, where soft-deleted container objects are logical objects for deleted containers that are maintained for recycling. The method includes recycling metadata of a matched soft-deleted container object for the new container. The method includes checking received input/output operations for the new container against already stored data of the matched soft-deleted container to recycle data and skip writes where they match.

Abstract: The fence system attaches to an aluminum or steel rectangular base post in concrete or the ground. The inside wall of a fence column slides over the base post. The fence column also has an outside wall around the inside wall. Each of three side of the fence column has an elongated slot, which receives one end of a slat. A bracket may secure the slat to the fence column. The fence system also has a gate of the same style as the rest of the fence. A lockset housing replaces one fence column. It receives slats on one side, and the lockset's latch projects from the other side. A hollow post has a slot facing the latch when the gate is closed. A latch cover is held by the slot, and an extension of the latch cover extends along the lockset housing to block surreptitious opening the gate.

Abstract: A computer-implemented method for detecting data storage errors includes storing first data in a first block corresponding to a first virtual volume, storing second data in a second block corresponding to a second virtual volume, generating parity information for the first data and the second data, and storing the parity information in non-volatile memory at a location corresponding to the logical block address to produce stored parity information. A system and computer program product corresponding to the above method are also disclosed herein.

Abstract: Aspects of the present invention disclose a method, computer program product, and system for stale data recovery using virtual storage metadata. The method includes one or more processors generating a primary virtual storage metadata structure having virtual address areas for a data chunk. Each area includes a plurality of most recent updates of metadata for the data chunk. The metadata of each update includes a sequence number for the update and a pointer to the physical location of the data. The method further includes one or more processors generating an overflow virtual storage metadata structure for multiple virtual address areas. The overflow metadata structure includes updates that have overflowed from the virtual address areas. In addition, wherein an oldest update in a full virtual address area of the primary virtual storage metadata structure includes a link to an overflow location.

Abstract: Described are techniques for managing data locations of derived storage objects. The techniques include accessing a primary metadata tree providing a lookup path using a virtual address to locate data for a primary object in physical storage pointed to by a leaf node of the primary metadata tree and providing a sub-tree from a leaf node of the primary metadata tree associated with the primary object, the sub-tree providing lookup paths using virtual addresses for derived objects. Wherein a derived object is a view of the primary object at a specific point in time, with copy leaf nodes of the sub-tree pointing to stored data of the derived objects. The techniques further include maintaining an ancestry graph associated with the sub-tree with the ancestry graph linking derived object identifiers to provide an ancestral chain lookup to identify derived object identifiers of the closest stored physical data of a derived object.

Abstract: An analysis system includes a data retrieval module that retrieves claimline data for a period of time. The claimline data includes multiple billing codes and corresponding prices associated with a provider. An analysis module receives the claimline data from the data retrieval module, determines whether a changepoint exists in the billing codes in the claimline data, determines a statistical parameter of changepoints per day during the period of time, and identifies a chargemaster increase for the provider in response to the statistical parameter of changepoints exceeding a threshold. An alert module, in response to identification of a chargemaster increase, publishes an alert that a chargemaster increase has occurred. The alert includes the provider's identification, a chargemaster increase date, a claimline number, a changepoint number, the billing code identification, or a price of the billing code at the changepoint. The alert transforms a user interface displayed to a user.
