Paragraph Number

81

Each packet is associated with one container. In a preferred embodiment, containers are limited to an erase block so that at or near the beginning of each erase block a container packet can be found. This helps limit data loss to an erase block with a corrupted packet header. In this embodiment, if the object index is unavailable and a packet header within the erase block is corrupted, the contents from the corrupted packet header to the end of the erase block may be lost because there is possibly no reliable mechanism to determine the location of subsequent packets. In another embodiment, a more reliable approach is to have a container limited to a page boundary. This embodiment requires more header overhead. In another embodiment, containers can flow across page and erase block boundaries. This requires less header overhead but a larger portion of data may be lost if a packet header is corrupted. For these several embodiments it is expected that some type of RAID is used to further ensure data integrity.
