Patent ID: 8321521

Claim:
A method for cache optimization in a hybrid solid state drive and spinning drive cache architecture, the method comprising: receiving a content object at a content delivery network (CDN) from a customer for storage, the CDN having a plurality of points of presence (POPs) geographically distributed across the Internet; analyzing information related to the content object to determine if storage at one POP of the plurality of POPs will be on a solid state drive (SSD), where the information is from the application layer or above in the open systems interconnection (OSI) model; storing the content object on the SSD; receiving a request for the content object from an end user at the one POP, where the request corresponds to an universal resource identifier (URI); determining that the content object is stored on the SSD rather than a magnetic drive; retrieving the content object from the SSD; and delivering the content object to the end user.
