Abstract

The present invention relates to memory to memory communication and storage for hybrid systems. Under the present invention, a data stream is received on a first computing device of a hybrid system. An attempt is made to store the data stream on the first computing device up to a per stream limit and a total storage limit of the first computing device. It is then determined whether to store at least a portion of the data stream on a second computing device of the hybrid system that is in communication with the first computing device. This decision is based on the per stream limit and the total storage limit of the first computing device as well as a per stream limit and a total storage limit of the second computing device. Thereafter, the at least a portion of the data stream and a control signal are communicated to the second computing device for storage.

Claims
