Techniques for memory management are described. A memory management data structure may include a tree structure of nodes each representing a free memory portion of a size used as a key value. The tree may be a modified AVL tree with nodes sorted based on key values corresponding to free memory portion sizes. The data structure may include a first list representing a memory map corresponding to different memory portions where each entry of the first list represents a memory portion with an associated memory address range that is not contiguous with respect to any other memory address range of any other memory portion represented by an entry on the first list. Each entry of the first list representing a free memory portion may be associated with a node of the tree structure.

Memory management techniques

A technique provides secure access to a set of credentials within a data storage system. The technique involves obtaining a unique identifier (e.g., a hostname which is unique to the system) and a set of stable values (e.g., machine-generated codes which are random to users of the system); and, in response to a storage request from a client application, storing a set of credentials of the client application within a data security mechanism of the data storage system. The set of credentials is in encrypted form when stored within the data security mechanism of the data storage system. The technique further involves configuring the data security mechanism of the data storage system to provide the set of credentials in non-encrypted form in response to new fingerprints matching a system fingerprint which is formed at least in part from the unique identifier and the set of stable values.

Described are techniques for processing a memory dump file. It is determined whether a memory dump file associated with a previous processor failure exists. In response to determining that the memory dump file exists, preliminary analysis of the memory dump file is performed. The determining step and the preliminary analysis are performed as part of rebooting a processor from the previous failure of the processor.
