Abstract
Disclosed herein are related to a system and a method for offloading distributed parity calculations from a server including a plurality of solid-state drives (SSDs) in communication with a host via a host interface. Each SSD includes a processor. The processor of each SSD may be configured to access a host address space via the host interface, determine parity information for data stored across a plurality of buffers in the host address space, and output the parity information to the host interface.
Claims20
A system comprising:
- a RAID device implemented by a plurality of solid-state drives (SSDs) in communication with a host, each SSD comprising a non-volatile memory device and a processor, the processor in each SSD configured to:
- access a subset of a stripe of data generated by the host;
- determine parity information for the subset of the stripe of data;
- and
- output the parity information to a parity buffer external to the SSD.
