Abstract
A method, system and computer program product for data replication comprising receiving an IO at a first storage processor (SP), sending metadata corresponding to the IO to a second SP, receiving an acknowledgement from the second SP indicating the second SP received the metadata and send the IO down an IO stack.
Claims18
A system for data replication, the system comprising:
- a storage system, the storage system comprising a storage medium, a first storage processor (SP) having a first splitter, a second SP having a second splitter;
- and
- computer-executable logic operating in memory, wherein the computer-executable program logic is configured for execution of:
- receiving an IO at the first SP;
- sending metadata corresponding to the IO to the second SP;
- receiving an acknowledgement from the second SP indicating the second SP received the metadata;
- and
- send the IO down an IO stack of the storage system.
5 more elements
A computer program product for use in replication comprising:
- a non-transitory computer readable medium encoded with computer executable program code for data replication, the code configured to enable the execution of:
- receiving an IO at a first storage processor (SP) of a storage system, wherein the storage system has a second SP;
- sending metadata corresponding to the IO to the second SP;
- receiving an acknowledgement from the second SP indicating the second SP received the metadata;
- and
- send the IO down an IO stack of the storage system.
3 more elements
A computer implemented method for data replication, the method comprising:
- receiving an IO at a first storage processor (SP) of a storage system, wherein the storage system has a second SP;
- sending metadata corresponding to the IO to the second SP;
- receiving an acknowledgement from the second SP indicating the second SP received the metadata;
- and
- send the IO down an IO stack of the storage system.
