Claim:
1. A method for prefilling data into a cache memory based on historical data to reduce warm up time of a flash based cache memory, the method comprising: determining in a local storage network of a plurality of servers that a first server associated with a flash based cache memory is no longer operational and requires replacement; replacing the first server with a second server; upon startup of the second server, employing a cache prefill mechanism to generate hints in a cache knowledgeable networked device for a flash based cache memory associated with the second server, wherein the hints are a form of reference to find data instead of pushing data into the flash based cache memory; and receiving the hints into the second server to know how to build the flash based cache memory associated with the second server, wherein the hints are references to frequently accessed blocks of data in the first server based on historical data, the hints including starting addresses and block lengths.
