Abstract
A system and method for offloading network processes from main processors of a storage system and performing them on parallel processing modules. Embodiments of the present invention allocate resources such as memory and/or buffers to particular connections between various storage operating system processes or between storage operating system processes and a network interface. Connections are identified by a connection identifier (CID) and are assigned particular buffers according to parameters such as buffer availability, connection priority, and/or maximum allocation thresholds. A connection associated with a CID is guaranteed access to a certain number of dedicated buffers. Deadlock is avoided even when an operating system process associated with a different CID attempts to exhaust available memory and/or buffers because such processes will only have access to their own allocated resources.
