Low latency communications for nodes in replication relationships

A system comprising:

• a host interface configured to connect to a host server;
• and
• a processing module configured to receive through the host interface a service request that requests modification of a target storage object in a storage platform and being configured to respond to the service request by performing a process comprising:
• using configuration information for the storage platform to identify in the storage platform a first storage node that maintains the target storage object and a second storage node that maintains a backup storage object that replicates the target storage object;
• and
• transmitting data for the modification from the first storage node to both the second node and the third node.

A storage platform, comprising:

• at least one processor;
• and
• memory storing instructions that, when executed by the at least one processor, cause the storage platform to:
• receive, at a first node in the storage platform, a service request that requests modification of a target storage object, the first node using configuration information to identify in the storage platform a second node that maintains the target storage object and a third node that maintains a backup storage object that replicates the target storage object;
• transmit data for the modification from the first node to both the second node and the third node, the second node using the data from the first node to perform the modification of the target storage object;
• cause the second node to send an update request to the third node, the update request not including the data;
• and
• in response to the update request from the second node, use the data the third node received from the first node to modify the backup storage object.
