Content Addressable File Store
The Content Addressable File Store (CAFS) was a hardware device developed by International Computers Limited (ICL) that provided a disk storage with built-in search capability. The motivation for the device was the discrepancy between the high speed at which a disk could deliver data, and the much lower speed at which a general-purpose processor could filter the data looking for records that matched a search condition. Development of CAFS started in ICL's Research and Advanced Development Centre under Gordon Scarrott in the late 1960s following research by George Coulouris and John Evans who had completed a field study at Imperial College and Queen Mary College on database systems and applications . Their study had revealed the potential for substantial performance improvements in large-scale database applications by the inclusion of search logic in the disk controller. In its initial form, the search logic was built into the disk head. A standalone CAFS device was installed with ...
