Speakers:
David Byte – SUSE
Matt Curley – HPE

Recorded at SUSECON 2016 as session TUT92092

The effort to characterize performance for various use cases in Ceph deployments is a continuing, but important process. This session will discuss the use cases and configuration, along with a benchmarking methodology and the results. Some scenarios covered would be object with and without journals, block with and without cache tier, and some OS tuning in relation to those.

Matt Curley – HPE

Recorded at SUSECON 2016 as session TUT92090

When implementing Ceph in the enterprise, best practices and enterprise-ready hardware are critical to success. SUSE and HPE have worked together and produced several designs that reduce risk for enterprise customers, while enabling the use of leading edge, open source software defined storage. This session will review specific attributes of HPE hardware configurations in relation to use cases to help the attendee understand design decisions made around performance, availability and supportability.

Recorded at SUSECON 2016 as session TUT91787

SUSE Enterprise Storage is based on the Ceph Software-Defined Storage technology. It enables a multitude of block, object, and even file storage use cases, and its flexibility allows it to be configured as required for many different scenarios. The hardware environment can be similarly tailored. This is a sizable decision matrix, but leads to an environment optimally tuned for the required balance between performance, functionality, and cost. Based on twenty years of experience with distributed systems, the goal of this presentation is to make you confident in your choice of Ceph for your use case and to build an architecture you can trust.

Beginning with choosing the appropriate access method for your workload, we then continue to introduce the algorithms and technologies in Ceph as they relate to resilience and High-Availability. We will discuss the considerations involved in optimizing a distributed storage system for reliability, availability, and durability of data and fault tolerance. We will look at the performance of Ceph in degraded and recovery scenarios, and how to reduce exposure. This affects the choice of hardware, the approach to feature selection, and system architecture. We will also talk about operational procedures to reduce unplanned downtime, speed-up recovery, and improve supportability.

Getting the Most Out of the ‘btrfs’ Filesystem

SUSE originally introduced the btrfs filesystem to enable snapshot/rollback for the operating system, and thus help drive the mission-critical data center. Btrfs can do more for you, though, and we will look at three technologies and their use cases:
1. Deduplication: The filesystem is able to find duplicates on the block level and thus minimize the size of your data on the storage medium. This might be especially useful when you are running many containers on your system.
2. Compression: For specific data types, compressing the data on the disk transparent to the application and the user is an efficient way to handle large amounts of data. On some architectures, this can even be accelerated via specific CPU features.
3. Send-receive: Btrfs’s send-receive is a filesystem feature that has recently reached stability and maturity and is thus ready for production use. It allows the user to export a subvolume of a filesystem in a simple and efficient manner as a single data stream. The exported subvolume can be stored and used to recreate the subvolume on the original filesystem, or to import that subvolume on another filesystem.

In addition, we may look at typical questions and answers in and around btrfs.

Speakers:
Dirk Mueller – SUSE
Adam Spiers – SUSE

Recorded at SUSECON 2016 as session TUT91720

This session provides an overview about how SUSE OpenStack Cloud’s deployment orchestration handles the OpenStack configuration and gives a technical deep dive in how to trouble shoot issues in your OpenStack Cloud environment. The focus of the talk is to give you enough information to start digging into the internals in order to learn how the individual components interact, including the latest information about SUSE OpenStack Cloud 6.

Adam Spiers and Dirk Mueller from the SUSE OpenStack Cloud engineering team will be there to interactively handle any questions you might have.

Speaker:
Klaus Kämpf – SUSE Linux

Recorded at SUSECON 2016 as session TUT91637

The combination of Elasticsearch, Logstash, and Kibana, commonly known as ‘ELK’, provide a state-of-the-art tool stack to monitor and analyze logs.

This tutorial gives a brief introduction to these tools and best practices how to deploy and use them. Special focus will be given to ELK in the context of SUSE Manager and SUSE Storage.

Stefan Schneider – Amazon Webservices

Recorded at SUSECON 2016 as session TUT91614

This case study shows how a cluster built on SUSE Linux Enterprise High Availability Extension can be used to build extremely reliable SAP HANA database failover architectures in the public AWS cloud. The audience will learn how a SUSE High Availability cluster, combined with the AWS cloud, allows customers to implement SAP architectures which:
– are hardened against any local data center failure
– are standardized and can be automated and used worldwide
– have increased security since all configuration changes of the cluster will be strictly limited to the required resources
– set new standards for auditability since all configuration changes will be tracked by the AWS cloud infrastructure.

Networking Approaches in a Container World

Recorded at SUSECON 2016 as session TUT91589

Networking has always been a complicated and delicate topic. Things get even more complicated in the world of containers, where lots of containers are continuously being created and moved over entire data centers.

Several choices are available, each one having a slightly different implementation and its own peculiarities. This leads to a lot of confusion when a networking solution has to be chosen.

This talk illustrates how the major networking solutions for Linux application containers work. We’ll address their implementation details, their positive and negative aspects and how they influence the deployment of distributed applications.

As more and more users are starting to consider Docker in production environments, people have realized that having Docker alone is not enough. Instead, the community is gearing towards orchestration solutions: tools, frameworks and practices that deal with how containers are deployed on production and how administrators can monitor all this without going crazy.

Join us for this brief journey into SUSE’s orchestration choice: Kubernetes.
