METHOD OF CHANNEL CONTENT REBUILD IN ULTRA-HIGH CAPACITY SSD |
摘要 |
A method of restoring user data in a modular solid-state drive including memory channels coupled to respective ones of non-volatile memory cards, the method including: upon physical replacement of a defunct memory card of the non-volatile memory cards with a new non-volatile memory card, and power on of the modular solid-state drive, retrieving a firmware segment and a system segment of the modular solid-state drive from unaffected memory channels of the memory channels not coupled to the new non-volatile memory card; rebuilding a firmware of the modular solid-state drive based on the retrieved firmware segment; rebuilding a data mapping table associated with the non-volatile memory cards based on the retrieved system segment; and restoring full integrity of the user data originally stored on the non-volatile memory cards based on the rebuilt data mapping table and data from the unaffected memory channels. |

1. A method of restoring user data in a modular solid-state drive comprising a plurality of memory channels coupled to respective ones of a plurality of non-volatile memory cards, the method comprising:
upon physical replacement of a defunct memory card of the plurality of non-volatile memory cards with a new non-volatile memory card, and power on of the modular solid-state drive, retrieving a firmware segment and a system segment of the modular solid-state drive from unaffected memory channels of the plurality of memory channels not coupled to the new non-volatile memory card; rebuilding a firmware of the modular solid-state drive based on the retrieved firmware segment; rebuilding a data mapping table associated with the plurality of non-volatile memory cards based on the retrieved system segment; and restoring full integrity of the user data originally stored on the plurality of non-volatile memory cards based on the rebuilt data mapping table and data from the unaffected memory channels. |
