A method and system directed to improve effectiveness and efficiency of cache and data management by differentiating data based on certain attributes associated with the data and reducing the bottleneck to storage. The data-aware cache differentiates and manages data using a state machine having certain states. The data-aware cache may use data pattern and traffic statistics to retain frequently used data in cache longer by transitioning it into Sticky or StickyDirty states. The data-aware cache may also use content or application related attributes to differentiate and retain certain data in cache longer. Further, the data-aware cache may provide cache status and statistics information to a data-aware data flow manager, thus assisting data-aware data flow manager to determine which data to cache and which data to pipe directly through, or to switch cache policies dynamically, thus avoiding some of the overhead associated with caches. The data-aware cache may also place clean and dirty data in separate states, enabling more efficient cache mirroring and flush, thus improve system reliability and performance.

Information is more efficiently distributed between master and slave information handling systems interfaced through a blocking network of switches by storing the information on switches within the blocking network and distributing the information from the switches. As an example, an application distribution module located on a leaf switch distributes an application, such as an operating system, to connected slave nodes so that the slave nodes do not have to retrieve the operating system from the master node through the blocking network. For instance, a PXE boot request from a slave node to the master node is intercepted at the leaf switch to allow the slave node to boot from an image of the operating system stored in local memory of the leaf switch.
