DescriptionIt has come to a historical point where we should
reconsider storage controller’s architecture to keep
pace with the explosive growth of big data and fast
emergence of new storage media technologies. We
introduce a storage controller with built-in
intelligence, referred to as DPU for Data-storage
Processing Unit. DPU manages, controls, analyzes, and
classifies data at the place where they are stored. The
idea is to place sufficient intelligence closest to the
storage devices that are experiencing revolutionary
changes with the emergence of storage class memories.
Machine learning logics are a major part of DPU that
learns I/O behaviors inside the storage to optimize
adaptively I/O performance, data reliability, and
availability for a variety of applications. By learning
production I/Os, page writes are clustered before they
are programmed to flash blocks, resulting in 10x
reduction of flash block erasures in flash SSD,
dramatically extending the life time of flash memories.
DPU efficiently implements in-situ data intensive
processing tasks such as string/text search and data
conversions, which alleviates I/O bus pressure. Our
results have shown over 10x performance improvements for
simple string search and data
serialization/deserialization applications compared with
traditional systems.
