Data migration between a raid memory and a dispersed storage network memory
First Claim

1. A method comprises:
- determining whether to convert data between a redundant array of independent disks (RAID) format and a dispersed storage network (DSN) format;
when the data is to be converted from the RAID format to the DSN format, retrieving the data from a RAID memory to produce retrieved RAID data;
converting stripe-block data of the retrieved RAID data into a plurality of sets of encoded data slices; and
outputting the plurality of sets of encoded data slices to at least one of the RAID memory and a DSN memory for storage therein.

Abstract
A method begins by a processing module determining whether to convert data between a redundant array of independent disks (RAID) format and a dispersed storage network (DSN) format. The method continues with the processing module retrieving the data from a RAID memory to produce retrieved RAID data when the data is to be converted from the RAID format to the DSN format. The method continues with the processing module converting stripe-block data of the retrieved RAID data into a plurality of sets of encoded data slices and outputting the plurality of sets of encoded data slices to at least one of the RAID memory and a DSN memory for storage therein.

8. A computer comprises:
-
an interface; a memory; and a processing module operable to; determine whether to convert data between a redundant array of independent disks (RAID) format and a dispersed storage network (DSN) format; retrieve, via the interface, the data from a RAID memory to produce retrieved RAID data when the data is to be converted from the RAID format to the DSN format; convert stripe-block data of the retrieved RAID data into a plurality of sets of encoded data slices; and output, via the interface, the plurality of sets of encoded data slices to at least one of the RAID memory and a DSN memory for storage therein. - View Dependent Claims (9, 10, 11, 12, 13, 14)
