Abstract
A method is used for uninterrupted data flushing in a storage system. A barrier in a page descriptor ring is determined to distinguish between a filling flushing work set (FWS) and a frozen FWS. A sequence number of an I/O request is compared to the barrier. A FWS corresponding to the I/O request is identified based on the comparison. The I/O request is committed to the identified FWS.
Claims12
A method for uninterrupted data flushing in a storage system, the method comprising:
- determining, in a page descriptor ring, a barrier to distinguish between a filling flushing work set (FWS) and a frozen FWS;
- comparing a sequence number of an I/O request to the barrier;
- identifying, based on the comparison, a FWS corresponding to the I/O request;
- and
- committing the I/O request to the identified FWS.
