I Need More Space, It's Not You It's BlueStore - Mohamad Gebai, SUSE

Users are sometimes confused when it comes to the used space reported by Ceph. This talk will help users understand the difference between expected, perceived and actually used space for an RBD on BlueStore use case. The examples shown in this talk are inspired by frequently asked questions on the Ceph mailing list by new users.

Nobody Knows What PGs are Good For, Only I Do - Danil Kipnis, 1&1 IONOS GmbH

While being a member of a team developing a distributed low-latency block-store, the author has been asked the question "why not just use ceph?" so often that he finally forced himself to understand some of the crush/rados basics.

It turned out, the block-store his team was working on was fully "declustered", while the ceph PG-indirection layer allowed to limit the level of "declustering".

PG concept is explained in various online sources but rather from a ceph configuration perspective. In this short talk, it is shown from a developer perspective on a very small example cluster what particular technical problem PG layer solves and how. Specifically, we illustrate the trade-off between cluster utilization during failure recovery and data loss probability due to coincident device failures and show how exactly PGs allow to favor the former or the latter.

Ceph BenchOps: Following DevOps Practices for Benchmarking Ceph - Ivo Jimenez, UC Santa Cruz

Benchmarking Ceph is conceptually easy: allocate compute resources, build and deploy Ceph, run benchmarks, gather and analyze results. In practice, and especially for people getting started with Ceph development and benchmarking, implementing this type of experimentation pipeline is a time-consuming effort. In this talk, Ivo Jimenez will present a community-based effort for creating and maintaining Ceph experimentation pipelines. These are used at UC Santa Cruz in research projects and classes to build, deploy and test Ceph in R&D scenarios. These pipelines follow DevOps principles (e.g. infrastructure-as-code) to allocate bare-metal resources, deploy Ceph using ceph-ansible, and run tests using CBT. Thanks to this effort, we are able to smooth the learning curve for students and others interested in starting to "get their hands dirty" with Ceph.

Ceph and NVMe/TCP - Orit Wasserman, Lightbits Labs

NVMe/TCP implements NVMe over fabric without any required changes to your network. It was ratified on Nov 18 and its implementation is part of the Linux kernel 5.0. In this talk, you will learn how Ceph can leverage its low latency and high throughput to reduce CPU load, and run applications such as RocksdDB and Apache Spark that expect storage to have those properties. You will also learn about the future plans for closer integration with Ceph to getting even more from NVMe/TCP.

Healthier Ceph Clusters with Ceph-medic - Alfredo Deza, Red Hat

ceph-medic is a small project that helps identify issues with a Ceph cluster that may be difficult to detect, even when using automation. The project lead will demonstrate how one can quickly discover issues with a running cluster, regardless of the deployment type (bare metal, containerized, or kubernetes), emphasizing on the importance of good reporting, clarifying errors or warnings for better deployments.

Using Devops Practices for Operating CEPH - Anders Bruvik, Safespring

Devops is a set of practices that aim to bring together Developers and IT Operations, and the goal is to shorten development lifecycle and bring IT in closer alignment with business goals.

So does it make sense to talk about Devops practitions when the "only" thing we do is operate a storage cluster like ceph? Yes - because modern system operation is becoming more and more about development - infrastructure as code is a term that describes how we increasingly are using development practises to configure IT systems.

In this talk, I will discuss why and how Devops matter for IT operation teams, and I will illustrate by bringing in examples from our experiences in building a distributed hybrid storage cloud in Sweden.

Brazilian Government Case - Brenno Martinez, Serpro

Developed by SERPRO, the Brazilian government IT company, the CNH Digital is a project that aims to replace traditional printed driver's license by a phone application. Ceph is responsible for storing drivers' fingerprints, signature and photo. Each license consists of 12 objects, and there are currently 600 million objects stored. There are multiple government services and systems, serving as central identification storage.

Configuring Ceph Deployments with an Easy to Use Calculator - Karl Vietmeier, Intel Corporation

When deploying a Ceph cluster, some of the most common questions include: How much RAM do I need? What is the recommended ratio of OSD storage size to the RocksDB size? Which CPU is the best? How many disks should I include per node? In this presentation, attendees will be shown, step by step, how to use an Excel template to properly answer the above questions and configure a Ceph cluster to meet end-user needs. Attendees will also be given the Excel template to use for their own deployments or in the field when working with end users.

Rapid Design and Effective Operating of a General Purpose Object Storage at RWTH Aachen University - Jonas Jansen, RWTH Aachen University

Collaborative, we started our S3 object storage design using Ceph together with four other partners (DUE, RUB, TU Dortmund, Univ. of Cologne), to build a disaster resilient storage. Since this was our first contact with this technology, our primary intention was to enable stakeholders to outline their needs in reliable metrics.

During the process, we added NAS storage resources. We did several setups, resulting in poor performance. Now are evaluating iSCSI gateway and Windows fileservers.

We developed compliance guidelines to ensure prompt delivery and availability within high-security standards and minimized costs.

These focus on:
Resiliency, by geo distributed setup
Efficiency, by erasure coding
Security, via automated testing and patching
Compliance and reduction of (human) workload, by automation and continuous delivery
High availability, by eliminating any single point of failure
