2 Legal Notices/disclaimer Intel technologies features and benefits depend on system configuration and may require enabled hardware, software or service activation. Learn more at intel.com, or from the OEM or retailer. No computer system can be absolutely secure. Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. For more complete information visit Tests document performance of components on a particular test, in specific systems. Differences in hardware, software, or configuration will affect actual performance. Consult other sources of information to evaluate performance as you consider your purchase. For more complete information about performance and benchmark results, visit Cost reduction scenarios described are intended as examples of how a given Intel- based product, in the specified circumstances and configurations, may affect future costs and provide cost savings. Circumstances will vary. Intel does not guarantee any costs or cost reduction. Results have been estimated or simulated using internal Intel analysis or architecture simulation or modeling, and provided to you for informational purposes. Any differences in your system hardware, software or configuration may affect your actual performance.

8 What is NVM Express Over Fabrics? Industry standard definition of NVMe over Data Center Fabrics Shares the same base Architecture and NVMe Host Software as PCIe Enables NVMe scale-out and low latency operations on Data Center Fabrics Non-PCIe Transports and Data Center Fabrics NVMe over Fabrics is the most efficient Block Interface on Data Center Fabrics

9 NVMe over Fabrics Standardization and Enabling Industry-wide NVMexpress.org TWG community defined NVMe Fabrics Dozens of companies participated in the definition over last ~18 months NVMe Over Fabrics Specifications were released on June 6 th 2016 Downloadable from Linux Kernel Host and Target Drivers available Integrated and tested with Linux 4.7-RC1 Kernel, plan is to upstream with 4.8 Kernel Intel SPDK User-Level NVMe over Fabrics Target Downloadable from

10 Commonality Between NVMe on PCIe and Fabrics The vast majority of NVMe is leveraged as-is for Fabrics NVMe host interface, NVM Subsystem, Controllers, Namespaces, Commands, Registers/Properties, Power States, Asynchronous Events, Reservations, etc. Allows for use of common NVMe Host software with very thin fabric dependent layers Primary differences reside in the discovery and queuing mechanisms ~ 90% Common Between PCIe and Fabrics

11 NVMe over Fabrics NVMe Command / Completion Delivery Fabric Capsules are messages with encapsulated common NVMe content Host to NVMe Controller * NVMe Controller to Host Data Section may be sent within the Capsule (as shown) or via a fabric type dependent data transfer mechanism, example RDMA_READ/RDMA_WRITE Data Transfer to/from Host resident buffer

12 NVMe over Fabrics Capsule Exchange Example Host NVMe Host Software Driver NVM Subsystem NVMe Controller Session Namespace ID 1 Namespace ID 2 NVMe Namespace A (Identify State) NVMe Namespace B (Identify State) Send NVMe CMD Capsule 1 6 RCV NVMe RSP Capsule RCV NVMe CMD Capsule 3 4 SND NVMe RSP Capsule Fabric Dependent Transport Fabric Dependent Transport Port Port 2 NVMe CMD Capsule 5 NVMe RSP Capsule
