Abstract: Examples disclosed herein relate to systems and methods for assigning an identifier to a node-based system. For example, systems and methods may: discover the plurality of nodes; determine a node of the plurality of nodes to be a controller node: authenticate, at a management component of the controller node, a respective identifier associated with each node of the plurality of nodes; and based on the authentication, assign a complex identifier to a complex comprising the plurality of nodes, wherein the complex identifier comprises the identifier associated with the controller node.

Abstract: Systems, methodologies, media, and other embodiments associated with performing a manipulation of a persistent memory using an extensible firmware interface are described. One exemplary method embodiment includes selectively refreshing a persistent memory from an EFI level application and providing to a user level application a signal concerning the persistent memory refreshing.

Abstract: A key fragment generator accepts a key string, such as from a key string generator, and produces a plurality of key fragments that can be entered by a human with a lower likelihood of error than if the human attempted to enter the original key string. A key defragmenter accepts a plurality of entered key fragments, reconstitutes the original key string from the entered key fragments and, optionally, provides the reconstituted key string to a software package or other license manager. The key fragment generator can produce “friendly” key fragments that are easier for humans to read and enter than the arbitrary character strings that characterize typical key strings. The key fragment generator can produce “error-detectable” key fragments. If an error-detectable key fragment is entered incorrectly, the key defragmenter can generate an error message and permit a user to enter the key fragment again. The key fragment generator can produce “error-correctable” key fragments.
