A computer-implemented method, according to one embodiment, is for integrating magnetic tape storage with a distributed disk file system. The computer-implemented method includes: registering for a subset of data operations that are recorded at a central location, where the central location is coupled to a plurality of distributed accessor nodes. A subset of available resources in one or more magnetic tape libraries that are coupled to the plurality of distributed accessor nodes are registered for and further managed. Moreover, a performance of the subset of data operations using the registered subset of available resources is scheduled. Supplemental data operations which correspond to the subset of data operations are also automatically received from the central location.

Magnetic tape integration with distributed disk file systems

A method includes determining dimensions of a web browser presenting a webpage, the webpage including an inner container and an outer container. The method modifies dimensions of the outer container of the webpage based upon an associated maximum height value, an associated minimum height value, and an amount of data within the outer container. Responsive to calculating a vertical height of the inner container, assigning a maximum height value and a minimum height value to the inner container. The method modifies dimensions of the inner container to a minimum height for the web browser to present the data of the webpage, based on the assigned maximum height value and minimum height value of the inner container. The method augments the web browser to include a scrollbar based on the modified dimensions of the outer container and the modified dimensions of the inner container.

Cognitive scrollbar

A method for recovering modified data lost from cache includes maintaining, in a cache of a primary storage system, a destage data structure indicating which modified data in the cache has been destaged. The method further maintains, in cache of a secondary storage system, a change recording data structure indicating which modified data has been replicated from the primary storage system to the secondary storage system. The method further merges the destage data structure with the change recording data structure to yield an updated change recording data structure. In the event modified data in the cache of the primary storage system is lost, the method utilizes the updated change recording data structure to determine which modified data in the secondary storage system is needed to restore the modified data lost from cache at the primary storage system. A corresponding system and computer program product are also disclosed.

Restoring data lost from battery-backed cache

This disclosure relates to a method, a system and a computer program product for tracking heat values. The method includes monitoring a first number of access operations to first data in each of a plurality of first source storage units during a cycle. The method further includes, for each of the plurality of first source storage units, calculating a first heat value based on the first number of access operations. Additionally, the method includes, in response to source data being moved from one of the first source storage units to a first target storage unit during the cycle, decreasing a calculated heat value of the one first source storage unit by a first value and increasing a calculated heat value of the first target storage unit by the first value.

Heat value tracking

In a storage management interface to manage host ports in a computing system having a server and one or more hosts, a user interface is provided to facilitate assigning host ports to an associated host. In one embodiment, the user interface detects unassigned host ports which have not been identified as being assigned to an associated host, and generates a graphical user interface (GUI) page indicating unassigned host ports. User selection of at least one of the unassigned host ports indicated in the GUI page is received as well as user selection of a host to assign to the selected unassigned host ports. Once the assignment is completed, data structures storing host port assignment configuration data are updated to indicate the host assigned to the selected host ports.
