摘要： A technique is provided for managing network devices and computer systems via a remote directory environment. The remote directory environment organizes various resources, such as servers, in a directory structure and provides access rights and restrictions to the resources based on groups or roles. A user with the proper access rights is then able to access the desired resource, such as a server, and create or modify management operations, device configurations, and other tasks. The subject device may then be notified of the new or modified operation, configuration, or task. The subject device also may routinely or periodically retrieve various management tasks from the remote directory environment.

摘要： Virtual media images of actual physical media resources, such as O/S boot files and software installation disks, are provided in a remote directory structure. The remote directory structure stores the virtual media images along with access rights of multiple authorized users, such that control is provided over the retrieval of the virtual media images and use of data/programs within the images. The virtual media images may be stored in blocks, or multiple sub-blocks/children, corresponding the actual media resources. Moreover, the remote directory server may simply store virtual media pointers, or location identifiers, which point to another storage location (i.e., a remote computer) having the actual data content of the virtual media image. Accordingly, the directory server processes a user request for a desired portion of the virtual media images by evaluating whether the user is one of the plurality of authorized users and whether the access rights of the user encompass the desired portion. If the user is authenticated and the desired portion is within the user's access rights, then the user may obtain the desired portion of the virtual media images.

摘要： A method for managing disk operations for a computer having a disk array utilizing parity fault tolerant and recovery techniques. A disk READ request results in a copy of the data and its associated parity information being stored in a reserved memory cache. Subsequent WRITE requests to the same disk sectors result in the computer system checking to see if a valid copy of the old parity and data are present in the reserved memory area for the purposes of generating new parity information without having to read the old data and parity information from the disk array.

摘要： A file system technique extends the life cycle of limited read/write media. Rewrite cycles of each file and/or each region of the media may be tracked. Different regions of the media are classified as static and dynamic based on their respective number of rewrite cycles. Static files are migrated to the more worn out or dynamic regions of the media, and dynamic files are integrated to the less worn out or static regions of the media. The file system is further sensitized by allocating a new file to an available region after a most recently used region. Where multiple versions of a data region exist, the file system marks a version of the data region as unstable after a certain number of rewrite cycles to the version and directs rewrite cycles to a subsequent version of the data region.

摘要： A computer system comprising at least one processor and associated cache memory, and a plurality of registers to keep track of the number of cache memory lines associated with each process thread running in the computer system. Each process thread is assigned to one of the plurality of registers of each level of cache that is being monitored. The number of cache memory lines associated with each process thread in a particular level of the cache is stored as a number value in the assigned register and will increment as more cache memory lines are used for the process thread and will decrement as less cache memory lines are used. The number value in the register is defined as the "process thread temperature." Larger number values indicate warmer process thread temperature and smaller number values indicate cooler process thread temperature. Process thread temperatures are relative and indicate the cache memory line usage by the process threads running in the computer system at a particular level of cache. By keeping track or "score" of the number values (temperatures) in each of these registers called "scoreboard registers," the scheduler algorithm of the computer operating system may objectively determine the most advantageous order for the process threads to run and which of the processors in a multi-processor system should execute these process threads. A scoreboard register may be reassigned to a new process thread when its associated process thread has been discontinued.

摘要： An apparatus and method for performing queued or posted disk read operations. The present invention determines the range of memory addresses to which data is to be transferred from a disk to memory and sets protection for this range of addresses. The present invention will issue a read complete signal upon issuing the read command and will prevent access to the range of memory addresses until the transfer of information from disk to memory is actually complete. Upon actual completion of the data transfer, the present invention will issue a read complete confirmation which will clear address range protection. The present invention may be implemented using special circuitry and a modified device drive to store the range protection addresses. Alternately, the method of the present invention may utilize paged memory techniques present within the microprocessor.
