Patent ID: 10275180

Abstract:
An Ethernet solid-state drive (Ethernet SSD or eSSD) system and corresponding method provide improved latency and throughput associated with storage functionalities. The eSSD system includes at least one primary SSD, at least one secondary SSD, an Ethernet switch, and a storage-offload engine (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 data associated with the first write command at the at least one secondary SSD. 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. The SoE controller may also receive read commands, data cloning commands and data movement commands from the remote device.
