Abstract
In general, embodiments of the invention relate to storing data by receiving a request to write data, in response the request, selecting a first RAID grid location in a RAID grid to write the data, determining a first physical address in persistent storage corresponding to the first RAID grid location, generating a first page comprising the data and first out-of-band (OOB), wherein the first OOB comprises a first grid geometry for the RAID grid, and a first stripe membership for the page within the RAID grid, and writing the first page to a first physical location in persistent storage corresponding to the first physical address.
