December 9th, 2016

Speakers:
Dan Elder – Novacoast
Daniel Harbison – Novacoast

Recorded at SUSECON 2016 as session CAS91463

While not every organization has yet embraced software defined storage, we’re going to discuss one who has. Novacoast is a SUSE customer who migrated from 3 legacy SAN environments to a single stretched Ceph cluster powered by SUSE Enterprise Storage. We’ll cover why the decision was made to migrate to Ceph, why SUSE Enterprise Storage was chosen, and lessons learned from the migration process. Future plans for the SUSE Enterprise Storage environment will also be discussed as will how the solution has enabled Novacoast to cut its storage budget in half.

Speaker:
Matthias Eckermann – SUSE

Recorded at SUSECON 2016 as session FUT92709

Linux as an operating system is ubiquituous, used everywhere, in a multitude of use cases, in various form factors and a dozen diverging deployment paths. And while the traditional way of a Linux distribution is driving most of the world’s IT, the paradigm is shifting: We all know about PaaS and CaaS, about Containers and MicroOSes, and we all “know” that those will replace the operating system – Do we know? Will they replace “the operating system”? – In any case, they are influencing how we think about “the operating system”.

This presentation will discuss how SUSE thinks about the next generation of SUSE Linux Enterprise, targeted for 2018, how SUSE’s next generation OS will answer the requirements of the IoT, Containers, PaaS, and Cloud world, without letting down traditional OS users.

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.

Speakers:
David Byte – SUSE
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.

Building Reliable Ceph Clusters with SUSE Enterprise Storage

Speaker:
Lars Marowsky-Brée – SUSE

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

Thorsten Kukuk – SUSE Linux GmbH
Jeff Mahoney – SUSE

Recorded at SUSECON 2016 as session TUT91782

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.
