The various implementations described herein include methods and systems for automatic management of data access acceleration in a computer system executing a plurality of clients. The method includes: receiving data access commands from two or more clients to access data in objects identified by the data access commands; and processing the data access commands to update access history information for portions of the objects identified by the data access commands. The method further includes: in accordance with the access history information, automatically identifying and marking for acceleration the portions of the objects identified by the data access commands that satisfy an access based data acceleration policy; and accelerating the object portions marked for acceleration, including accelerating data writes and data reads of the object portions to and from the persistent cache, where the persistent cache is shared by the two or more clients.

Automatic read and write acceleration of data accessed by virtual machines

A remote management module receives a command from a support server in response to the remote management module initiating a first secure, authenticated connection with the support server, wherein the remote management module is integrated with, and monitors a condition of, a processing system. The remote management module executes the command to generate a result that provides diagnostic data about the processing system. The remote management module reports the result to the support server upon the remote management module initiating a second secure, authenticated connection with the support server.

Remote support automation for a storage server

A support center receives an error message from a remote storage system indicating that an error, such as a kernel panic, has occurred on the remote storage system. The error message is processed to determine the type of error, whether the type of error is known and whether a solution is known for the type of error. If the type of error is unknown, a core file upload request is automatically generated and sent to the remote storage system.

Automatic core file upload

A core file that may be generated when a data storage system encounters a problem can be automatically and securely sent to a remote (e.g., offsite) support enterprise. Moreover, given the size of such files and the additional requirements associated with sending such files securely, the transmission of the core file may be monitored such that, if a problem occurs during the transmission, the pieces of the file that have been successfully transmitted are not resent, but merely those pieces that still need to be (successfully) transmitted. In this manner, the time and resources required to securely transmit such large files are more efficiently utilized.

Core file transfer

Thermal conditions within a computer unit are monitored. A system-level temperature sensor responds to intake cooling air. A subsystem-level temperature sensor responds to the temperature of a subsystem-level component, preferably a motherboard or a backplane. When the temperature sensed by of the system-level temperature sensor falls outside of a critical limit, it is determined whether the temperature sensed by the subsystem-level temperature sensor generally correlates with the temperature sensed by the system-level temperature sensor. If there is no correlation, the operation of the computer unit is continued.
