High Performance and Hardware Acceleration – With exponential data generation rate, specifically in applications like Deep learning, AI the demand for storage with high-bandwidth and great scalability that supports unstructured data format is increasing. To fulfill this need Samsung proposes DSS storage solution, which implements object Key-Value API on top NVMeOF SSD. The support of storage remote access protocols facilitates the disaggregation. Therefore, storage can be easily scaled. Besides object storage support and scalability, our architecture can provision the bandwidth demands for each application on each client server. This paper introduces our DSS Storage systems that support high-bandwidth per capacity for object-format data with an effortlessly scale-up feature. DSS uses some methods to deterministically provide bandwidth to the client sessions to mitigate the contention and starvation. Therefore, our storage design is essential for large concurrent multi-session workloads with intensive reads such as AI training.
