Abstract: Improved latency and throughput associated with storage functionalities are provided by an Ethernet SSD (eSSD) system and corresponding method. The eSSD system includes at least one primary SSD, at least one secondary SSD, an Ethernet switch, and a storage-offload (SoE) controller. The SoE controller may operate in a replication mode and/or an erasure-coding mode. In either mode, the SoE controller receives a first write command sent from a remote device to at least one primary SSD. In the replication mode, the SoE controller sends a second write command to the at least one secondary SSD to replicate at the at least one secondary SSD data associated with the first write command. In the erasure-coding mode, the SoE determines erasure codes associated with the first write command and manages distribution of the write data and associated erasure codes.
