Abstract: Embodiments relate to policy-based, multi-scheme data reduction for a computer memory. An aspect includes receiving a plurality of policy rules by a policy engine of the computer memory, wherein a first policy rule specifies applying a first data reduction scheme to data in the computer memory based on the data matching first characteristics, wherein a second policy rule specifies applying a second data reduction scheme to data in the computer memory based on the data matching second characteristics, wherein the first data reduction scheme is different from the second data reduction scheme. Another aspect includes determining, by the policy engine, that first data in the computer memory matches the first characteristics, and that second data in the computer memory matches the second characteristics. Yet another aspect includes applying the first data reduction scheme to the first data, and applying the second data reduction scheme to the second data.

Abstract: Embodiments relate to scheduling operations to perform on objects. A method for scheduling operations to perform on objects is provided. The method identifies a plurality of operations to perform on a plurality of objects each having at least one attribute. At least one of the operations has scheduling dependency on another operation. The method generates a numeric value for each of the objects from the attribute of the object. The method schedules the operations to perform on the objects based on the numeric values of the objects and the scheduling dependency.

Abstract: A network storage system comprises data storage, one or more file system APIs, and a metadata handler. The data storage can comprise file data and associated metadata. The file system APIs can be configured to read and write file data and metadata to and from the data storage. The metadata handler can have a library of functions for handling the metadata. The library can include a metadata blob creation function and a metadata blob extraction function. The metadata blob creation function cooperates with the file system APIs to read source metadata associated with specified file data and creates and populates a metadata blob from which a substantial copy of the source metadata can be generated. The metadata blob extraction function receives at least a metadata blob, extracts information from the metadata blob, and cooperates with the file system APIs to generate destination metadata, a substantial copy of the source metadata.

Abstract: A method for secure portable operating system interface (POSIX) directory traversing for opening and accessing files by inode number. The method includes receiving, by a process executed by a processor, a request for a ticket for traversing a file system. The process generates a secure key for a unique handle object based on the request for the ticket. An authentication code is generated for the ticket using a numeric file identifier and the secure key. In response to reading a directory with POSIX x and r permissions according to directory permission bits or an access control list (ACL), the ticket is returned including ticket information including the numeric file identifier, generation information and the authentication code. In response to a request to open a directory, the ticket information is validated based on the secure key. A directory is opened for reading using the validated ticket information and the unique handle.
