Efficient data transmissions between storage nodes in replication relationships

A process comprising:

• setting up a storage platform so that a first storage component in the storage platform is responsible for fulfilling service request targeting a volume and a second storage component in the storage platform maintains a copy of the volume;
• the second storage component receiving a service request with data for modification of the volume;
• the second storage component keeping a copy of the data and transmitting the data to the first storage component;
• the first storage component fulfilling the service request to modify the volume;
• the first storage component transmitting replication instructions to the second storage component, the replication instructions not including the data;
• and
• the second storage component using the replication instructions and the copy of the data to update the copy of the volume.
