Multi-streaming mechanism to optimize journal based data storage systems on SSD
Abstract:
A system and method for using multi-streaming with journal information (305) and data (325) is disclosed, when using an application (125) and/or a data storage system (120) that performs double-writes. A journal write request (310) can be sent with the journal information (305) specifying that the journal information (305) should be written to one stream (315). The data write request (320) can be sent with the data (325) specifying that the data (325) should be written to another stream (330). A controller (135) on the storage device (130) can then write the journal information (305) to a block (405, 410) associated with the first stream (315) and the data (325) to a block (415, 420) associated with the second stream (330).
