Pull Requests and Reviews for Good - Gregory Farnum & Sam Just, IBM

Wednesday December 4, 2024 11:40 - 12:15 CET

Auditorium B

You’ve built an amazing new feature for your Ceph use case and want to share it with the world. Now what? You make a pull request! Learn how to prepare and present your new work effectively and successfully within the Ceph community, and understand what you can expect from other contributors who are reviewing it.  Conversely, you are asked to review a PR, and maybe it needs work. How do you share feedback in a way that it’s heard and handled? Which feedback is worth sharing at which stage of the process? And what are you promising to everybody else when you provide that “Reviewed-by” tag? This talk is for anybody who writes or reviews code (or wants to!) in the Ceph project. Prepared and presented by two of Ceph’s original four tech leads, hear about pitfalls and tips developed submitting PRs, mentoring new developers, and reviewing code from drive-by contributors, Ceph startups, consultancies, and future maintainers!

Conditional End2end Tracing - Yuval Lifshitz, IBM & Deepika Upadhyay, Clyso GmBH

Wednesday December 4, 2024 14:15 - 14:50 CET

Auditorium B

End to end tracing can help debug latency issues between the RGW and the OSD, giving a complete picture of request flow, but tracing itself has a performance impact on the system. When your production system runs into issues, the last thing you want is to put it under more pressure! In this session we will demonstrate how to use Lua scripting on the RGW to turn opentelemetry based tracing only for some of the incoming requests. Allowing us to focus on the problem without slowing down the entire system.

Improving Ceph Economics with QAT Hardware Offload - Philip Williams, Canonical

Wednesday December 4, 2024 17:25 - 18:00 CET

Auditorium B

Ceph, the words most popular open source software defined storage system, has offered storage efficiency features such as block device compression, object compression and server-side object encryption for a number of releases. However, enabling these features has always come as a trade-off between the additional performance required (in terms of cores/GHz) vs the raw storage cost, ultimately driving users away from these features. In this talk we will walk through several different scenarios where Intel's QAT offload is used to enable these features without significant overhead to primary processing, and still yields greater performance without causing increased cost per GB.

Migrating AI/ML Data Pipelines for Real Time Streaming Applications from HDFS to Ceph - Vahideh Alinouri, Etraveligroup

Thursday December 5, 2024 10:50 - 11:25 CET

Auditorium B

Etraveligroup’s AI/ML team has migrated data pipelines from HDFS to Ceph to ensure efficient management and performance. To achieve this, they deployed Ceph RGW with a replicated data pool on NVMe disks to meet the technical demands and automation needs. The request flow involves migrating real time streaming applications and training datasets for machine learning that assist with real time sales analytics and automated pricing. The crucial migration steps include transferring production pipelines from HDFS to in-house object storage. Precise tuning is necessary to manage c-states, power saving, and IOMMU on physical servers and preventing write locking during the dynamic resharding process. Key factors such as failure domain, co-locating RGWs with OSDs or MONs, beast thread pool size, memory profiling, mclock profile, and the number of RGW services are essential for achieving the target metrics and ensuring a successful migration.

Understanding Ceph One Performance Counter at a Time - Marcel Lauhoff, Clyso GmbH

Thursday December 5, 2024 13:40 - 14:15 CET

Auditorium B

Let’s demystify Ceph performance counters by following the journey of data through the system, from the initial client I/O request to the moment it reaches the disk. We'll introduce performance counters, explaining what they are, how they work, and how to access them effectively. Using a simple workload, we'll analyze key Ceph performance counters to illustrate how data flows through various subsystems and what these metrics reveal about system performance. By understanding these metrics, attendees will gain insights into diagnosing issues and optimizing their Ceph deployments.

Ceph Notification at Scale: Notification V2, an Enterprise-Level Feature - Krunal Chheda, Bloomberg

Thursday December 5, 2024 14:25 - 15:00 CET

Auditorium B

Data powers Bloomberg’s financial products. Ceph clusters are the backbone of Bloomberg’s internal S3 cloud storage systems, which host this data and serve billions of requests a day. Given the importance of these cloud storage systems to the company’s broader infrastructure, it is crucial that any S3 feature we enable must be an enterprise-level feature that scales, provides telemetry, is secure, and has fault-tolerant capabilities. Working together with the community, Bloomberg has enhanced the existing notification feature built into Ceph enabling it to be used by Bloomberg and other enterprise users of Ceph. This talk will discuss all the work that went into building “notification_v2,” the new enterprise-class S3 notifications platform and all of its new features.

Arming Ceph: CI Enhancement and UADK Integration - Rongqi Sun, HUAWEI TECHNOLOGIES CO., LTD.

Thursday December 5, 2024 16:05 - 16:15 CET

Auditorium B

The ARM ecosystem is becoming increasingly robust, and ensuring the stability and high performance of Ceph on the ARM platform is crucial. Due to some reasons, the ARM CI has been almost abandoned in recent years. Over the past year, Rongqi's team has been actively fixing environment and software issues to maintain Ceph's operation on ARM. The team also continuously monitors Ceph's performance on ARM. In this Lightning Talk, he will showcase the achievements on the ARM CI up to now. Additionally, in the performance section, he will discuss how Ceph's integration with UADK (User Space Accelerator Development Kit, a general-purpose user space accelerator framework that uses shared virtual address (SVA) technology to provide a unified programming interface for hardware acceleration computing cryptography and compression algorithms) enables compression under low CPU load. The T version will include this by default.

Encrypting Data in Ceph: An Overview and Opportunities - David Mohren, 45Drives

Thursday December 5, 2024 16:50 - 17:25 CET

Auditorium B

Encrypting data in large storage platforms like Ceph has become a standard practice in the industry. However, when attempting to utilize these features in Ceph, a typical user may find the process overwhelming. One reason may be the lack of a consolidated Ceph Docs document that explains and compares the various encryption solutions available in Ceph. This could assist Ceph users in identifying the optimal solution for their specific use case. My objective is to provide a foundational overview of data encryption in Ceph and clarify the various encryption solutions currently available within Ceph. At the end I will talk about that none of the Ceph encryption solutions give a storage end-user the ability to figure out if someone other than authorized parties have tampered with the data. Therefore I will present a method on how to solve the problem. Our solution is to integrate AEAD ciphers into Ceph (as done in Azure,Google Cloud,AWS) and use OMAP to store the resulting authentication tags. My goal is to initiate a dialogue within the community to ascertain whether the solution I have developed is applicable within the context of Ceph and to get guidance on how to proceed from here
