Abstract
A computer system manages storage of data and associated management and/or control information. The system logically divides the storage into a plurality of address spaces with common addressing within each of the address spaces. In response to a request for a block of storage, the system allocates a block of storage at an address from one of the address spaces. The system also reserves another block of storage from another of the address spaces at the same address within the other address space to store corresponding management and/or control information. Next, data is written to the requested block of storage in the one address space, and management and/or control information is written to the other block in the other address space. Thus, the management and/or control information is not confined to the block which contains the actual data. Also, because the management and/or control information is stored at the same offset of this other address space as the offset of the data within the one address space, the management and/or control information can be readily located by using the offset of the data and an identification of this other address space.
