Traditional Storage Node consists of Compute, Networking and Storage elements. In this case, the entire node is a single failure domain and as such both data and meta data are maintained in storage. Emergence of CXL allows us to re-think the traditional storage node architecture. In future, the storage (behind CXL IO) and metadata memory (behind a CXL memory) can be disaggregated locally or across a bunch of storage nodes to improve the availability of the data. Further, memory persistence can be achieved at a granular level using CXL memory devices.

Computational Storage continues to gain interest and momentum as standards that underpin the technology mature. Developers are realizing that moving compute closer to the data is a logical solution to the ever-increasing storage capacities. Data-driven applications that benefit from database searches, data manipulation, and machine learning can perform better and be more scalable if developers add computation directly to storage.

Two veterans of the storage industry discuss the impact of hardware innovation to the common deployment methods used in SDS.

At scale, embedded storage solutions fall away in favor of distributed approaches that encapsulate and aggregate the many previous steps taken, bringing us to the common SDS methods we use today. The session speakers were present for many of these baby-steps and major milestones, providing a unique perspective to our current “state of the art.”

During the last two decades, the data center world has been moving to a “Software Defined Everything” paradigm. This has been taken care of mostly by hypervisors running on the x86 up to recently.

Applications desire for higher IOPS & bandwidth is driving innovations at the hardware level. This requires software stack awareness to harness the benefits. Multi-actuator drives represent the next big innovation in performance.

Security, unlike most technologies, is driven by changes to the threat landscape as well as the legal/regulatory responses. This BoF provides a forum to explore recent and anticipated developments. It may also serve as a forum to further explore details from the various SDC security and data protection sessions.
