STORAGE DEVICE RAID DATA WRITE INTERMEDIATE PARITY SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17716204 Titled 'STORAGE DEVICE RAID DATA WRITE INTERMEDIATE PARITY SYSTEM'
Simplified Explanation
The abstract describes a storage device system that uses RAID technology to write data. It consists of a storage subsystem and a volatile memory system. When the system receives data from a host, it first stores it in the volatile memory. Then, it stores a portion of the data in the storage system and generates parity data based on that portion. The parity data is also stored in the volatile memory. Finally, the system erases the portion of the data from the volatile memory.
Original Abstract Submitted
A storage device RAID data write intermediate parity system includes a storage device coupled to a host system and including a storage subsystem and a volatile memory system. The storage device RAID data write intermediate parity system receives first primary data from the host system, and stores the first primary data in the volatile memory system. The storage device RAID data write intermediate parity system then stores a first subset of the first primary data in the storage system, generates first intermediate parity data using the first subset of the first primary data, stores the first intermediate parity data in the volatile memory system and, in response, erases the first subset of the first primary data from the volatile memory system.
