NVMe and NVMe/oF

Session A-5: Accelerating Applications for a Competitive Edge

Storage developers and IT professionals should know about the many methods that are available for accelerating their storage systems to meet the demands of larger data streams, new applications (such as artificial intelligence and IoT), and extra requirements such as cybersecurity, privacy and scalability. Such methods include Ethernet-attached SSDs to avoid protocol conversions, use of multi-level flash to provide lower-cost archiving, and the implementation of Zoned Namespaces to allow the automatic tailoring of flash storage management to suit particular applications.

How Zoned Namespaces Improve SSD Lifetime, Throughput and Latency

The NVM Express Zoned Namespace (ZNS) Command Set interface is a new command set specification that defines the zoned storage interface for NVMe SSDs, allowing the storage device and host to collaborate on data placement. Compared to a typical SSD, a ZNS SSD can expose more of the physical media and has significantly higher steady write throughput, while improving I/O access latencies. This talk introduces the NVMe ZNS Command Set, the zoned storage model and the software ecosystem, and it provides an update on each. Furthermore, we show the benefits (lifetime, throughput and latency) of ZNS SSDs using real-world workloads and comparing them to typical SSDs. Link to Presentation

Software-Enabled Flash for Hyperscale Data Centers

To obtain the greatest efficiency at scale, the hyperscale data center is redefining digital storage. Using flash effectively and efficiently for stable and predictable latency is critical to achieving this goal in ever-changing cloud workloads. Software-enabled flash is a technology that redefines digital storage in a new way that combines software flexibility, host control and flash-native semantics into a flash-native API. Together with purpose-built flash-based modules, software-enabled flash maximizes the value of flash memory for large-scale cloud providers. This combination of technologies fundamentally redefines the relationship between the host and solid-state storage in a way that bypasses the overhead of legacy HDD storage to enable the use of flash at its natural speed under host control. This approach provides a pathway to flash-native architectures that include block, ZNS, custom flash-native implementations and much more. Link to Presentation

Making NVMe Drives Handle Everything from Archiving to QoS

Zoned Namespaces (ZNS) represent the first step toward the standardization of open-channel SSD concepts in NVMe. Specifically, ZNS brings the ability to implement data placement policies in the host, thus providing a mechanism to lower the write-amplification factor, lower NAND overprovisioning and tighten tail latencies. Following its counterpart in the high-capacity HDD world -- shingled magnetic recording HDDs -- ZNS is initially targeted at archival workloads. We believe that ZNS can also address the other core concept in the open-channel SSD architecture: I/O predictability. In this talk, we cover how the existing ZNS architecture can be suited for better host data placement and scheduling than traditional block I/O. Moreover, we introduce the concept of Zone Random Write Area and how it helps ZNS target multi-tenant environments. Link to Presentation

Accelerating Flash for a Competitive Edge in the Cloud and Beyond

NVMe's Zoned Namespaces functionality has created a large array of new opportunities for end users. This radical approach to NAND SSD data placement and management enables key technologies such as QLC to become mainstream, while also giving applications and users a better method to optimize and streamline operations, resulting in higher performance and longer life for flash. This talk addresses what these changes mean for real-life applications focusing on the most popular NoSQL databases, which are largely used in the cloud and many modern applications, spanning from Cassandra to MongoDB to Heterogeneous-Memory Storage Engine. The session discusses the results of benchmarks (such as YCSB and Socialite) that most represent real-life applications and uses the benchmarks to highlight the value and new opportunities that these new storage technologies bring to the market. We also cover different topologies and configurations like NVMe-oF to provide a thorough view of what this technology means for the real world. Link to Presentation

Session D-6: Optimizing NVMe-oF Storage with EBOFs and Open Source Software

Data-driven applications such as databases, analytics and AI/ML run much faster on multi-server systems when the available flash storage is networked to maximize usage. However, an obvious problem is how to network standard NVMe drives at reasonable cost while achieving high performance levels. One emerging solution involves creating an NVMe-oF Ethernet Bunch of Flash combined with the open source Heterogenous-Memory Storage Engine software. Trial runs show good performance with multiple workloads. Link to Presentation

Session C-8: IDC Real-World Applications and Solutions for Persistent Memory

E. Burgener, A. Nadkarni, S. Sesar and T. He

Persistent memory (storage at memory speeds) seems like an obvious gain for most applications. However, progress in the area has been quite slow because of the lack of standards, suitable interfaces and systems software. Customers have bought into the latest entries from companies such as Intel in search of needed performance boosts at reasonable cost. New hardware and software should lead to even further market penetration in a variety of applications, including AI/ML, real-time analysis, high-performance computing, virtual and augmented reality, IoT and cybersecurity.

SSDs

Session D-5: Storage Processors Accelerate Database Operations

Tony Afshary, Mark Mokryn and Edward Bortnikov

Storage processors offload legacy software to high-performance hardware. Legacy storage stacks waste flash capacity and performance, forcing users to deploy expensive, overprovisioned SSDs. For example, high write amplification limits low-cost technologies such as QLC and PLC to low-performance applications. Storage processors add value for many data-intensive applications, including basic block storage benchmarks as well as database applications. An important point is that they work with industry-standard SSDs. Link to Presentation

Session A-6: Which SSD Is Best for Your Application?

B. Berg, R. Walsh, K. Malik, M. Bjørling, M. Twitto

NVMe SSDs are now mainstream in most data center applications. But how about applications that require higher performance, lower latency, more flexibility, easier management, or more scalability? For them, a variety of choices now exist. There are Ethernet SSDs, NVMe-oF SSDs, Optane SSDs, MRAM SSDs, zoned namespace (ZNS) SSDs, key-value SSDs, computational storage SSDs, and other variations. How do storage designers determine when their applications require something other than the standard device -- and which one would do the job best? Obvious use cases have emerged for some variations, while still others are currently a solution waiting for a really good problem.

Session B-7: Ethernet-Attached SSDs Lead to Higher-Performing Storage

Ethernet-attached SSDs offer a simple way to increase storage performance and reduce cost. They are an upgrade to current designs based on PCIe switches, Ethernet NICs and compute modules used to do protocol conversions such as NVMe-oF on Ethernet to NVMe on PCIe. The new designs replace PCIe switches with cheaper Ethernet switches, and make the compute modules (a common limiting factor in performance and scalability) unnecessary. JBOFs using Ethernet-attached SSDs have been constructed, and the resulting systems show excellent throughput. The same method could be used to provide a simple, inexpensive interface for persistent memory as well.

Evolution of Ethernet-Attached NVMe-oF Devices and Platforms

As the NVMe-oF ecosystem continues to mature, storage systems now have design choices for the type of external and internal fabrics to use, as well as the various attach points. Several Ethernet-based protocols (RoCE, iWARP, TCP) have also emerged as design choices for storage fabrics and interfaces. There are unique properties and trade-offs associated with those choices, as well as different implementations, acceleration paths and management models. An industry discussion has ensued on how close to the storage the Ethernet I/F should be carried: data center, rack or even device. This presentation provides a broad view of Ethernet-attached NVMe-oF disaggregated storage systems and what it would take for successful wide deployment of those systems. Link to Presentation

Matt Hallberg

Benefits of Native NVMe-oF SSDs

NVMe over Fabrics enables large numbers of NVMe-based storage arrays to be networked, helping to improve asset utilization, increase application performance and reduce Capex and Opex. Currently the most common implementation approach being considered is at the storage array level. An alternative and more cost-effective approach is to deploy NVMe-oF natively at the SSD level. This approach can yield greater scalability, performance, reliability, availability and serviceability while helping to contain compute and memory investment costs. This approach also overcomes the limitation of PCIe by leveraging market-proven Ethernet-based networks. Link to Presentation

Session D-7: New Ways to Improve SSD Management and Performance

As NVMe becomes more entrenched in data centers, new methods have emerged for improving its management and performance. Approaches such as I/O determinism allow system software to vary underlying placement algorithms to suit particular approaches. There are also new ways to monitor the health of SSDs and to optimize their performance using AI methods.

Optimizing NVMe Drives for Your Applications

IBM's Zurich Research Laboratory developed SALSA (Software Log Structured Array), a flexible flash translation layer that aggregates and manages a group of inexpensive SSDs. It lives up to its name by adding a bit of spice to the managed SSDs. SALSA has a robust and simple LSA that allows for efficient garbage collection and reclamation, and in doing so can provide reduce write amplification to ensure higher endurance and performance. This talk explains how SALSA has evolved to work effectively with Zoned Namespaces. Link to Presentation

Jonmichael Hands

Monitoring the Health of NVMe SSDs

NVMe technology was built from the ground up for SSDs, and the original NVMe specification included a standard SMART (Self-Monitoring, Analysis and Reporting Technology) log that monitored errors, device health and endurance. Many capabilities have been built into NVMe technology since, including enhance error reporting, logging, management, debug and telemetry. These capabilities can be built into tools ranging from open source management tools to OEM management consoles to help support monitor the status and health of the SSD (such as notifying users when an SSD failure occurs). Link to Presentation

Optimizing SSD Performance With AI and Real-World Workloads

The best way to optimize SSD performance is to use real-world applications, but how should designers analyze the effects of attempts to improve wear leveling, task scheduling, pre-fetching and caching and to minimize write amplification and garbage collection? Furthermore, how can they predict I/O stream traffic? The answer is to use AI techniques to develop a model from the results obtained using the workload data. The model learns from the results presented to it during training and then optimizes performance during execution. This talk presents shows the use of these methods on advanced XL-flash SSDs in which a recurrent neural network serves as the underlying model and produces substantial performance improvements.
