Beyond Particle Physics: The Impact of Ceph and OpenStack on CERN's Multi-Datacenter Cloud Strategy - Enrico Bocchi & Jose Castro Leon, CERN

Wednesday December 4, 2024 10:55 - 11:30 CET

CERN IT operates a large-scale storage and computing infrastructure at the service of scientific research and its user community: Ceph provides block, object, and file storage at a scale of 100 PBs, while OpenStack provisions bare-metal nodes, VMs, and virtual networking managing more than 450k CPUs. With the advent of a new computing center a few kilometers away from the main campus, compute and storage resources have been re-imagined to extend the capabilities offered by the infrastructure, while putting upfront clear design choices to favor availability and ease of operations. . In this presentation we report on how the new computing center was designed to host cohesively compute and storage resources, how integration with the existing computing center was achieved, and which new capabilities have been unlocked thanks to the newly-built DC. For Ceph in particular, we share insights on achieving data locality with compute resources, deploying a multi-site object storage service, and running a CephFS service that spans across both data centers.

Keeping Ceph RGW Object Storage Consistent - Jane Zhu, Bloomberg

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

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.During the intensive usage of the Ceph RGW object storage with multi-site settings, we encountered different types of data inconsistencies, such as bucket-index and RADOS object inconsistency, unfinished transactions, and multi-site replication inconsistency, etc. These inconsistencies may potentially be caused by software bugs, race conditions, system timeout, and other reasons. Since we cannot guarantee the system is always bug-free and operating smoothly, it’s crucial that we can identify the inconsistency – should it happen – and fix or report it. While there are existing tools and code in place to help address some of these issues, their usage has limitations. As such, we are proposing a scalable and extensible bucket scrubbing approach to systematically check and identify and fix any inconsistency in the RGW object storage system at the bucket-level, if possible. This talk will discuss the design of this bucket scrubbing system and a prototype of it that we are implementing at Bloomberg.

Bringing a Ceph Based Enterprise Email System Into the Field - Danny Al-Gaaf, Deutsche Telekom AG

Wednesday December 4, 2024 13:30 - 14:05 CET

Deutsche Telekom operates a growing email system with several million accounts and billions of emails stored on traditional NFS. Six years ago we introduced librmb (librados mailbox) to the community, a universal open source library to store emails in a Ceph cluster. Librmb uses RADOS to store email directly in Ceph to achieve maximum performance through parallel access from many email gateways simultaneously, for millions of active customers. Email systems are much too complex to be simulated in a way which would allow to verify if the switch to librmb will work for a large number of users. Therefore a field test with active customers was necessary to provide an educated guess on the behavior of the final setup. This presentation will cover the results from artificial and real field tests with more than 1 million accounts/users. The results include the experience and learnings of migrating from the existing email system into Ceph, an extended time of running the system and from migrating the accounts out of the test system. We will provide an insight into our learnings, found issues, potential solutions and an outlook into our next steps towards a Ceph based email system.

The Art of Teuthology - Patrick Donnelly, IBM, Inc.

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

The Ceph project has used the Teuthology testing framework for much of its history. The custom framework is used to schedule batch jobs that perform e2e testing of Ceph. This is orchestrated using a suite of YAML fragments to alternate test modes, configurations, workloads, and other parameters. Teuthology assembles these fragments into a static matrix with potentially dozens of dimensions ultimately producing a combinatoric explosion of jobs which are evaluated, in practice, as smaller subsets for scheduling. We will explore an alternative directed graph model for constructing jobs from a suite of YAML fragments using path walks. Code adapted to this model has been constructed to produce subsets in linear time and provide Lua scriptable control of YAML fragment generation. The latter new feature empowers us to test Ceph with more rigor and completeness. For example, upgrade suites can be constructed using all possible versions of Ceph that are valid upgrade paths to a target release. We will explore this and other enhancements in depth. The audience can expect to leave with a firm and visual understanding of how QA is performed on Ceph and a vision for the future testing.

Exploring RocksDB in RGW: How We Manage Tombstones - Sungjoon Koh & Ilsoo Byun, LINE Plus Corporation

Wednesday December 4, 2024 15:00 - 15:35 CET

LINE, a global mobile messenger, has adopted Ceph as its main object storage. It is used to store different kinds of data, such as log files and application data. Thanks to its scalability, billions of objects are stored in our clusters. However, over time, object deletions lead to the accumulation of tombstones in RocksDB, resulting in delays during iteration. Slow iteration not only impacts LIST operation but also stalls subsequent requests. To address this issue, we first collected RocksDB metric called "skip count", which indicates the total number of tombstones detected during iterations. We then deployed a new job which compacts OSDs with high skip counts to prevent stalls. Additionally, we analyzed the pattern of tombstones and found out that a few prefixes account for over 80% tombstones, throughout the entire OSD. Based on this observation, we propose range-based compaction. In this presentation, we will first explain the basics of RocksDB and its role in Ceph Object Storage. Then, we will share our experience how we handled the RocksDB issue. Lastly, we will discuss our proposal for range-based compaction, which could further optimize overall system performance.

Wednesday December 4, 2024 16:40 - 17:15 CET

Drawing from the insights gained from attending Ceph Days 2022, Customers previous talks, and my personal experience with ServiceMesh deployments, I have observed that many organizations need help implementing a cluster-wide rate limiting and metrics visibility across their RGW and Buckets. We discover a range of exciting use cases as we explore Envoy's capabilities in rate limiting, filtering, and collecting metrics on S3 activities executed against RGW. These include header-based filtering for multi-region deployments, additional OAuth token enforcement, and the ability to monitor user-to-bucket metrics without post-processing command outputs at ease. To illustrate these capabilities, I will lead a hands-on lab demonstration, showcasing Envoy's frontend role for RGW on various use cases.

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

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

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.

Supporting 3 Availability Zones Stretch Cluster - Kamoltat (Junior) Sirivadhna, IBM

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

A Ceph cluster stretched across 3 zones faces a potential scenario where data loss can occur due to unforeseeable circumstances. An example of such a scenario is when we have 6 replicas spread across 3 datacenters with a min_size of 3 and the setup is intended to prevent I/O from happening when there is only 1 datacenter available, however, there is an edge case where a placement group (PG) becomes available due to a lack of safeguarding during the process of temporary PG mappings in order ensure data availability. This scenario poses a risk when the sole surviving data center accepts writes, and then suddenly the 2 unavailable data centers come back up. At the same time, the surviving data center suddenly goes down, which means we would have a data loss situation. To prevent such a scenario from happening, we created a solution that utilizes an existing feature in stretch mode that would restrict how we choose the OSDs that would go into the acting set of a PG. This talk will take a deep dive into how this feature is implemented in the latest Ceph upstream as well as other features that improve the user experience with stretch cluster in the latest Ceph upstream release.

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.

SWITCH: Operations, Data Management and Automation - Theofilos Mouratidis, SWITCH

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

SWITCH is the national research and education network (NREN) of Switzerland, a non-profit organisation that provides services to the universities and schools of the country. In the storage circle of the cloud team at SWITCH, we maintain and procure Ceph clusters mainly for S3. We have 3 iterations that differ in terms of automation and features namely OSv1/2/3. We currently develop the latest iteration using Ansible in a GitOps way, where the code is the source of truth and changes to the code automatically deploy configuration changes to various clusters. In this session, we will talk about the OSv3 Ansible collection and configuration management repos, where from defining an inventory that looks like the `ceph orch host ls` output and a short yaml file, we can immediately bootstrap clusters that connect together and provide multisite S3, without any manual steps. Now that we deploy our new clusters using the new technologies, we are in the migration phase where we try to maintain the old dying clusters (OSv1/2) and slowly migrate S3 data to the new ones with minimal or no user intervention.

Benchmarking: Repeatable & Comparable - Trent Lloyd, Canonical (Ubuntu)

Thursday December 5, 2024 15:10 - 15:45 CET

Your goal when benchmarking should be to ensure that the results are both continuously repeatable and fairly comparable to previously attempts. This is all too easy to get wrong. Benchmarking of any kind often presents tricky business, but storage has always presented particularly difficult challenges as even the simple Hard Drive has interesting performance characteristics that vary greatly depending on the workload or even chance. You might hope that was solved by SSDs, and that is true to an extent for real workloads, but they tend to give even more misleading results during synthetic benchmarks. I'll work through many different causes of inconsistent results in benchmarking both individual components and over-all performance of a Ceph cluster, with specific examples and graphs of real attempts. Items covered include - Working set size - Bi-modal SSD performance due to flash block management - Thin provisioning - Bandwidth limitations of SSDs, Backplanes, PCIe buses, CPUs, Memory and Networks - Filesystems - Caches of all kinds - Inconsistencies from benchmarking freshly deployed Ceph clusters - Benchmarking tools (Don't use anything other than fio, aws-cli is slow) - And more

Cost-Effective, Dense, and Performant Prometheus Storage via QLC - Anthony D'Atri, Dreamsnake Productions

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

Prometheus is the metrics ecosystem of choice for modern computing, with exporters for Ceph, RAID HBAs, Redfish, time synchronization, and the panoply provided by node_exporter. Exporters are scraped multiple times per minute for effective queries, each ingesting as many as several housand metrics per system. Data may be kept locally or in external solutions including Ceph RGW. Retention of a year or more is valuable for trending and comparisons. A moderate-size deployment can easily fill tens or hundreds of terabytes. As retention and cardinality grow, so does processing. Prometheus will GC and flush its WAL every two hours, which can manifest visible yet spurious artifacts in visualization tools like Grafana and false alarms from alertmanager rules. Rotational media just don't cut it. While HDDs of capacities as large as 30TB are available, rotational + seek latencies, SATA stenosis, interminable resilvering, and SMR severely limit their viability. SSDs are increasingly viable as HDD replacements. We can improve cost and density by tailoring to the workload: intermittent sequential writes, and frequent random reads. This is a classic workload for modern QLC SSDs.

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

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

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
