Unlocking the potential of NVMe-oF and Software Defined Storage thanks to programmable DPUs

Sebastien Le Duc

Abstract

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.

In parallel, a new communication protocol to interface with SSDs has been specified from the ground-up, allowing to fully exploit the levels of parallelism and performances of all-flash storage: NVMe, and NVMe-oF. NVMe-oF promises to enable the performances of direct attached all-flash storage with the flexibility an TCO savings of shared storage. To fully unlock the benefits of NVMe-oF while keeping the software defined paradigm, we believe a new kind of processor is needed: the Data Processing Unit, or DPU.

Evolution of Load-Store I/O to meet the needs of Compute and Storage Infrastructure

Dr Debendra Das Sharma

Abstract

Emerging and existing applications with cloud computing, 5G, IoT, automotive, and high-performance computing are causing an explosion of data. This data needs to be processed, moved, and stored in a secure, reliable, available, cost-effective, and power-efficient manner. Heterogeneous processing, tiered memory and storage architecture, infrastructure accelerators, and infrastructure processing units are essential to meet the demands of this evolving compute and storage landscape. These requirements are driving significant innovations across compute, memory, storage, and interconnect technologies. Compute Express Link* (CXL) with its memory and coherency semantics on top of PCI Express* (PCIe) is paving the way for the convergence of memory and storage with near memory compute capability. Pooling of compute, memory, and storage resources with CXL interconnect will lead to rack-scale efficiency with efficient low-latency access mechanisms across multiple nodes in a rack with advanced atomics, acceleration, smart NICs, and persistent memory support. In this talk we will explore how the evolution in load-store interconnects will benefit the compute and storage infrastructure of the future.  

Computational Storage: from edge to cloud, which technology for which use case?

Jerome Gaysse

Abstract

When designing a new system from the ground up, there are multiple ways to implement Computational Storage (CS) in a new architecture, depending on the form factor, the computing type (CPU or FPGA), the environment (edge, cloud).
This talk will present a review of the available CS technologies, and will explain how to evaluate which CS technology provide the best benefits for specific workloads, including storage services, database and AI. System architecture examples will be described with use case simulation results.

SMB3 over QUIC: Deep Dive and Document Updates

Obaid Farooqi 

Abstract

This talk will give an overview of what’s been added to the SMB3 protocol documentation for the latest release as well as a deep dive into the using SMB3 over the QUIC transport. The SMB3 protocol is broadly deployed in enterprise networks and contains strong protection to enable its use more broadly. However, historically port 445 is blocked and management of servers on TCP have been slow to emerge. SMB3 now is able to communicate over QUIC, a new internet standard transport which is being broadly adopted for web and other application access. In this talk, we will provided updated details on the SMB3 over QUIC protocol and explore the necessary ecosystem such as certificate provisioning, firewall and traffic management and enhancements to SMB server and client configuration. 

Learning Objectives: You will learn the details about SMB3 on QUIC; how it works, the architecture and performance comparison with SMB on TCP. Documentation updates related to SMB3 on QUIC will also be presented.

Finding the right data in an ocean of bits

Glyn Bowden

Abstract

Data science and machine learning are hugely popular topics at the moment, but those topics don’t do the actual work involved justice. Most of the time is not spent on tweaking the features of the model or pruning it to optimise for edge deployment. It's spent finding, assessing and them wrangling the data into something meaningful and useful that the algorithm can get to work on. In this talk we will explore some of the challenges facing the data hunters and look to some methods that can help speed the process along and allow for repeatable data operations.

Development of software-defined storage engine for 25 million IOPS

Dmitrii Smirnov

Abstract

Modern CPU and NVMe technologies have made a breakthrough and have opened up new horizons for Software-Defined Storage performance. However, not everyone is aware of the new SDS performance potential or considers it unreachable, so current software solutions are not ready for the new hardware capabilities. We want to share our knowledge about developing an SDS engine that achieves 25 million IOPS per one storage node. We will describe challenges we met and resolved while developing a universal engine for the Linux kernel and for the SPDK. We will show performance optimizations and CPU-friendly hints, and discuss how to avoid mistakes when developing all-flash storage, how not to waste millions of IOPS, and how to reach new hardware limits.

Object Storage for Cloud Native Applications

Nicolas Trangez & Vianney Rancurel

Abstract

We are now seeing the emergence of new generation application workloads in big data analytics, AI/ML, in-memory databases - and on the edge, that are creating new demands on storage. These applications are being deployed and managed on Kubernetes, with a need for fast and agile access to storage. Automated provisioning through CSI, the Container Storage Interface for block and file volumes is already being embraced. In this session, we will discuss the fit of object storage for unstructured data generated by these applications, and the emergence of object storage provisioning operators such as COSI, the Container Object Storage Interface from CNCF and Kubernetes’ SIG-Storage, as a way for simplifying and automating object storage provisioning.

Evaluating Cache performance using cloud storage traces

Effi Ofer

Abstract

Designing a cache front end for cloud storage calls into question of the effectiveness of the popular LRU cache eviction policy versus the FIFO heuristic. Several past works have considered this question and commonly stipulated that while FIFO is much easier to implement, the improved hit ratio of LRU outweighs this. Two main trends call for a re-evaluation: the very large scales of cloud storage which makes managing cache metadata in RAM infeasible, and new workloads which possess different characteristics. We model the overall cost of running LRU and FIFO in a very large scale cache and evaluate this cost using traces taken from real world object store system. While there are lots of traces for file and block storage, to date, there has been a dearth of traces for Object Storage. To address this gap, we collected object storage traces from the IBM Public Cloud. IBM has anonymized these traces and made them available to the public at the SNIA IOTTA repository.

Ceph RGW Message Queue API for Serverless Computing

Yuval Lifshitz & Dr Huamin Chen

Abstract

A proposal to support AWS SQS API natively in Ceph RGW, for advanced Serverless computing use cases.

Bucket notification has become widespread in many applications including AI/ML and Edge Computing. We have demonstrated that Ceph Rados Gateway (RGW) bucket notifications trigger Serverless functions including Knative and AWS Lambda. Such workflows can be characterized as event push and event driven.

We’ve identified yet another workflow that allows Serverless computing frameworks to be more preemptive in auto scaling. The workflow is based on the event queue polling model, the opposite of event push, that allows Serverless computing frameworks, such as KEDA, to preemptively scale the functions based on the queue length. Such workflow is more advantageous and lightweighted in dealing with highly bursty event traffic and reducing Serverless function cold start overhead.

In order to support this workflow, we propose a new set of message queue APIs, modeled after AWS SQS, for Ceph RGW. In this talk, we’ll present the overview and planning of this technology to the community.

MASSé: A high-performance storage solution for 3D XPOINT™ and Flash SSDs

Jack Zhang

Abstract

MASSé is the Media Aware Smart Storage Engine. While Solid-State-Drives (SSDs) have become commonplace in data-center and cloud, innovative new storage media technologies such as 3D XPOINT™ media or Intel® Optane™ media and Quad-level Cell (QLC) flash have emerged to address the ever-increasing need for better performance and lower total cost of ownership (TCO). Our observation is that existing storage algorithms and data structures - from application, through kernel, and to filesystem - have not evolved to take full advantage of the high-impact capabilities of these new storage media technologies. Consequently, applications are not fully benefitting from the perfor-mance capabilities of 3D XPOINT™ media, and the mi-gration from today’s mainstream TLC (Triple-level Cell) SSDs to low-cost QLC SSDs has been slowed. MASSé includes optimizations designed to take full advantage of the latest Solid-State-Drive media innovations, allowing applications to achieve better performance with 3D XPOINT™ media, as well as speed the migration to more cost-effective QLC SSDs. MASSé is lightweight open-source software that resides in user space, independent from applications and the kernel system. It can be inte-grated as a plug-in module into any storage system, ena-bling a tiered storage architecture that is more capable of delivering on the performance capabilities of 3D XPOINT™ media and the low-cost advantages of QLC SSDs.

Challenges of building an Application-Aware Regional Disaster Recovery Solution for Kubernetes

Veera Deenadhayalan & Shyam Ranganathan

Abstract

Kubernetes does not offer a native disaster recovery solution that can handle disaster of an entire region. While Kubernetes can be deployed as a stretch cluster to tolerate failure of a data center or an availability zone, it is typically not stretched across regional boundaries due to the high latency between regions. This talk outlines the challenges of building an application-aware regional disaster recovery solution on the Kubernetes platform.

High-speed optimized SPDK implementation on a 80 cores manycore processor.

Jean-Francois Marie & Remy Gauguey

Abstract

As you know, the Storage Performance Development Kit (SPDK) provides a set of tools and 
libraries for writing high performance, scalable, user-mode storage applications. 
 
Kalray’s MPPA® manycore architecture proposes a unique 80-cores system.
 
A manycore processor is characterized by an apparent grouping from a software point of view of cores 
and their portion of the memory hierarchy into computing units. This grouping can delimit the scope 
of cache consistency and inter-core synchronization operations, include explicitly addressed local working 
memories (as opposed to caches), or even specific data movement engines and other accelerators.
Computing units interact and access external memories and processor I/O through a communi¬cation device that 
can take the form of a network-on-chip (NoC).
The advantage of the manycore architecture is that a processor can scale to massive parallelism by replicating 
the computing units and extending the network on chip, whereas for a multi-core processor the replication 
applies to the core level.
 
For storage purposes, the internal processor clusters are configured with one dedicated cluster as a control 
and management plane, and the remaining four clusters as four independent data planes. 
We have implemented SPDK so that it provides a unique scalable platform that can deliver 
high performances on an 80-core system.
This presentation will explain how we have ported SPDK on our processor core, and what unique pieces of
technologies have been developed in order to coordinate with the processor internals.
We will also explain how the platform can scale.

Long Term Retention for Medical AI Applications

Simona Rabinovici-Cohen

Abstract

SNIA Self-contained Information Retention Format (SIRF) is an ISO/IEC 23681:2019 standard that defines a storage container for long term retention. SIRF enables future applications to interpret stored data regardless of the application that originally produced it. SIRF can be beneficial in domains that need to keep data for long periods and enable search, access, and analytics on that data in the far future. The standard also includes examples of SIRF serialization on the cloud and on tapes.

Artificial Intelligence (AI) in medical applications is an emerging area that aims to analyze medical big data to improve screening, diagnosis and treatment of disease. One challenge of this area is providing storage systems to efficiently store and preserve the data for future analysis within the patient lifetime and beyond. The European Union H2020 BigMedilytics project includes a pilot to analyze clinical and imaging data for early prediction of breast cancer treatment outcomes. In this talk, we’ll describe SIRF and how it can be applied in the BigMedilytics breast cancer pilot.

Ozone, the story of a billion keys

Lokesh Jain

Abstract

Object stores are known for ease of use and massive scalability. Unlike other storage solutions like file systems and block stores, object stores are capable of handling data growth without increase in complexity or developer intervention. Apache Hadoop Ozone is a highly scalable Object Store and is a spiritual successor of HDFS. It can store billions of keys and hundreds of petabytes of data. With the massive scale there is a requirement for it to have very high throughput while maintaining low latency.

This talk discusses the Ozone architecture and design decisions which were significant for achieving high throughput and low latency. With petabytes of data and billions of keys Ozone has a scalable metadata layer. The talk will detail how Ozone supports this layer without compromising throughput or latency. Such a massive scale requires Ozone to be scalable in terms of client connections and amount of data read and written to the store. The talk will discuss the challenges faced and the corresponding design solutions. Also it would touch upon Ozone’s goal of reaching trillion objects and possible challenges.

Introducing Fabric Notifications, from awareness to action

Howard Johnson & AJ Casamento

Abstract

Marginal links and congestion have plagued storage fabrics for years and many independent solutions have been tried. The Fibre Channel industry has been keenly aware of this issue and, over the course of the last two years, has created the architectural foundation for a common ecosystem solution. Fabric Notifications employs a simple message system to provide registered participants with information about key events in the fabric that are used to automatically address link integrity and congestion issues. This new technology has been embraced by the Fibre Channel community and has demonstrated a significant improvement in addressing the nagging issues. In this informative session, storage experts will discuss the evolution of this technology and how it is a step toward a truly autonomous SAN.

2-Dimensional Erasure Coded LTO Tapes with RAIL Library configuration

Turguy Goker

Abstract

Active archives enable media companies to quickly, efficiently and cost-effectively search their vast volumes of content to retrieve and process assets they need. Erasure coding can be used to protect this content, but it typically requires more resources and increases content retrieval latencies, limiting performance. This paper proposes a technology that offers higher content durability and availability with minimum latencies and less storage overhead than a two-copy scheme. INSIC Tape Roadmap forecasts 35% Areal Density and 25% Track Density CAGR, requiring future track pitches to be below 1000nm, such as a recently published 580TB tape technology demo requiring 50nm track pitch. At these dimensions, considering that tape must operate in open environmental conditions, drives and media failures will be dominated by correlated errors requiring more protection than an internal format erasure correcting code (ECC) and two-copy scheme can provide to achieve more than 11-nines durability.

Current replication techniques don’t provide resource-friendly protection and can’t meet 11-nines durability unless more than two copies are used. In a typical tape archival scenario, a carefully designed multi-dimensional erasure coding mechanism can bring novel efficient resource utilization, better availability and durability, and more environment-friendly operation for distributed tape systems with less overhead than two-copy protection. To reduce repeated read cycles and I/O bandwidth requirements, increase durability, and improve local recoverability, we propose multi-dimensional, hierarchical overlay erasure coding with interleaved codewords. Its unique mathematical coding structure and special interleaving allows local repair and almost uncorrelated errors, helping maximize local tape operations - i.e. minimize the system’s tape, drive and robot requirements.

Thanks to special metadata handling, the proposed system’s byproducts are the self-describing erasure-coded tapes friendly to disaster recovery and content transportation. These combined contributions help increase the lifetime of different subsystems of tape and improve the archival storage system’s performance.

Improvements to Accessing Network Files from Linux: SMB3 client progress

Steve French

Abstract

The Linux SMB3 client continues to be the most active network/cluster filesystem on Linux over the past year, and the progress on Samba server and the Linux kernel server has helped add new features to the SMB3.1.1 client in Linux, and made these improvements even more important.

It has been a great year for SMB with the addition of many security improvements, many performance improvements including to caching and RDMA (smbdirect) as well as dramatic improvements to multichannel, and new sparse file features. Support for the Witness protocol (allowing transparent movement to a different server) has been added, as well as the new more feature rich Linux mount API. In addition support for the final piece of the optional SMB 3.1.1 POSIX protocol extensions was completed. Tooling has been improved with many new features added to tools like smbinfo, and support for easily getting and setting more auditing and security information.

This presentation will go through some of the new features added to the Linux client over the past year, and demonstrate the great progress in access various types of network storage, including the cloud (e.g. Azure), and Samba and Windows server and also the new Linux kernel server (ksmbd).

ksmbd(cifsd) status update

Namjae Jeon

Abstract

ksmbd(cifsd) is a new SMB3 kernel server which implements server-side SMB3 protocol. The target is to provide optimized performance, GPLv2 SMB server, better lease handling (distributed caching). The bigger goal is to add new features more rapidly which are easier to develop on a smaller, more tightly optimized kernel server. Many changes and improvements have been made since cifsd(ksmbd) was introduced to earlier SDC 2019. This talk will give ksmbd overview and the current status update.

Access control and ID mapping on the Linux SMB Client

Shyam Prasad

Abstract

The SMB protocol was designed long after Unix was created, and as a result supported concepts like globally unique identities and rich ACLs that are in Windows, but not in Linux. User identity and access control are very relevant to the Linux SMB3 client, as it acts as a bridge between the world of Windows-like-filesystems (including the cloud) and the world of Linux filesystems, and has the hard task of translating security information from the more complex Samba and Windows world, to the simpler Linux/POSIX model.

There are three key problems:
Id-mapping: Who the user is? And how does it map to the user that the server understands?
Authentication: Can the user prove his/her identity?
Access control: What permissions does the user have for this file?

This talk will discuss and demonstrate the different ways that the Linux client can be configured to map POSIX permissions (mode bits) to ACLs, and the implications of using these configurations. It will discuss the different authentication choices, especially how to leverage Samba’s winbind for easy to use and highly secure Kerberos authentication and key refresh. In addition it will discuss how to integrate with Samba’s winbind to map user identities (from the local Linux client’s UIDs to globally unique SIDs) and the various alternatives like “idsfromsid”. Recent improvements in cifs-utils for managing ACLs and auditing information remotely will also be discussed, which can make managing Samba server easier in some cases.

The network is the computer revisited

Christopher Hertel

Abstract

Under the raised floor tiles of data centers around the world you will find tangles of multi-colored cables and strange, other-worldly interconnects. The swill from the overflowing bitbuckets seeps its way down to this level, where even DevOps fear to venture. In the darkness of these digital depths, strange new creatures evolve. The new new breed of SmartNICs is an example. SmartNICs are similar to the familiar TOE and iSCSI cards, but the latest wave of evolution are based upon multi-core RISC-based I/O processors known as Data Processing Units, or DPUs.

This talk will cover a little project that started up just about a year ago. The Zambezi project aims to create an SMB3 Offload Engine, aimed at DPUs and SmartNICs. We will look at SMB3 message processing from the Syntactic to the Semantic layers and discuss how this processing can be broken down into layers so that much (if not all) of it can be offloaded to (general case) SmartNIC or other network infrastructure device.
