Quick-And-Easy Deployment of a Ceph Storage Cluster with SLES with a Look at SUSE Studio, Manager and Build Service
Quick-and-Easy Deployment of a Ceph Storage Cluster with SLES With a look at SUSE Studio, Manager and Build Service Jan Kalcic Flavio Castelli Sales Engineer Senior Software Engineer [email protected] [email protected] Agenda Ceph Introduction System Provisioning with SLES System Provisioning with SUMa 2 Agenda Ceph Introduction SUSE Studio System Provisioning with SLES SUSE Manager System Provisioning with SUMa 3 Ceph Introduction What is Ceph • Open-source software-defined storage ‒ It delivers object, block, and file storage in one unified system • It runs on commodity hardware ‒ To provide an infinitely scalable Ceph Storage Cluster ‒ Where nodes communicate with each other to replicate and redistribute data dynamically • It is based upon RADOS ‒ Reliable, Autonomic, Distributed Object Store ‒ Self-healing, self-managing, intelligent storage nodes 5 Ceph Components Monitor Ceph Storage Cluster Object Storage Device (OSD) Ceph Metadata Server (MDS) Ceph Block Device (RBD) Ceph Object Storage (RGW) Ceph Clients Ceph Filesystem Custom implementation 6 Ceph Storage Cluster • Ceph Monitor ‒ It maintains a master copy of the cluster map (i.e. cluster members, state, changes, and overall health of the cluster) • Ceph Object Storage Device (OSD) ‒ It interacts with a logical disk (e.g. LUN) to store data (i.e. handle the read/write operations on the storage disks). • Ceph Metadata Server (MDS) ‒ It provides the Ceph Filesystem service. Purpose is to store filesystem metadata (directories, file ownership, access modes, etc) in high-availability Ceph Metadata Servers 7 Architectural Overview 8 Architectural Overview 9 Deployment Overview • All Ceph clusters require: ‒ at least one monitor ‒ at least as many OSDs as copies of an object stored on the cluster • Bootstrapping the initial monitor is the first step ‒ This also sets important criteria for the cluster, (i.e. -

Technology Overview New Features Backupedge
Technology Overview - BackupEDGE™ Introduction to the New Features in BackupEDGE 3.x Technology Overview BackupEDGE has a long history of providing reliable data protection for New Features many thousands of users. As operating systems, storage devices and BackupEDGE 3.x usage needs and tendencies have changed over the years, it has continuously met the challenge of providing inexpensive, stable backup and disaster recovery on a variety of UNIX and Linux platforms. Clients routinely find new and clever ways to utilize products. Storage devices have taken on new and exciting features, and incredible capacities. Products designed years ago had built-in limits that were thought to be beyond comprehension. Today, these limits are routinely exceeded. The need for data security is even more apparent. We’re constantly asking our To continue to meet the evolving needs of our clients, we are always clients what tools our asking what features of our products they find most useful, what products need to serve them improvements we can make, and what new requirements they have. better. We’ve used this knowledge to map out new product strategies designed to anticipate the needs of the next generation of users, systems and storage products. This has resulted in the creation of BackupEDGE 3.x, with a combination of internal improvements, new features and enhanced infrastructure designed to become the backbone of a new generation of storage software. Summary of Major Changes and Additions BackupEDGE 3.x features include: • Improvements to partition sizing, UEFI table cleanup after DR, and SharpDrive debugging (03.04.01 build 3). • Support for Rocky Linux 8.4 and AlmaLinux 8.4 (03.04.01 build 2). -

Linux Distribution - a Linux OS platform information API Release 1.3.0 Nir Cohen, Andreas Maier Sep 04, 2018 Contents 1 Overview and motivation 3 2 Compatibility 5 3 Data sources 7 4 Access to the information 9 5 Consolidated accessor functions 11 6 Single source accessor functions 17 7 LinuxDistribution class 19 8 Normalization tables 23 9 Os-release file 25 10 Lsb_release command output 27 11 Distro release file 29 Python Module Index 31 i ii Linux Distribution - a Linux OS platform information API, Release 1.3.0 Official distro repository: distro official repo Contents 1 Linux Distribution - a Linux OS platform information API, Release 1.3.0 2 Contents CHAPTER 1 Overview and motivation The distro package (distro stands for Linux Distribution) provides information about the Linux distribution it runs on, such as a reliable machine-readable distro ID, or version information. It is the recommended replacement for Python’s original platform.linux_distribution() function, but it provides much more functionality. An alternative implementation became necessary because Python 3.5 deprecated this function, and Python 3.8 will remove it altogether. Its predecessor function platform.dist() was already deprecated since Python 2.6 and will also be removed in Python 3.8. Still, there are many cases in which access to OS distribution information is needed. See Python issue 1322 for more information. If you want to jump into the API description right away, read about the consolidated accessor functions. 3 Linux Distribution - a Linux OS platform information API, Release 1.3.0 4 Chapter 1. Overview and motivation CHAPTER 2 Compatibility The distro package is supported on Python 2.7, 3.4+ and PyPy, and on any Linux or *BSD distribution that provides one or more of the data sources used by this package. -
Latest on Centos
Published on Tux Machines (http://www.tuxmachines.org) Home > content > Latest on CentOS Latest on CentOS By Roy Schestowitz Created 13/12/2020 - 2:59pm Submitted by Roy Schestowitz on Sunday 13th of December 2020 02:59:47 PM Filed under Red Hat [1] Harish Pillay (IBM/Red Hat): The vibrancy of open source projects/products[2] In 2002, Red Hat, in response to customer needs for supportable Linux operating systems, Red Hat created Red Hat Advanced Server 2.1 which in 2003, was renamed as Red Hat Enterprise Linux 2.1. This change to a subscription based model of consumption of Red Hat Enterprise Linux, upset the community who have been consuming Red Hat Linux since the launch of RHL in 1994. Yes, I was part of that user community that was not happy with the change. And, yes, I did try to see what I could do to continue to benefit from what RHL used to provide in the new RHEL space. I was not alone in that pursuit. There were many efforts around the world to create a RHL-like system available at no cost to the end user but based on the RHEL code base. The code base of RHEL is available for download because Red Hat complies to and exceeds the requirements of the GNU General Public License of making available the code that goes into a product. [See here for a twitter thread on how Singtel and Aztech have failed to respect the terms of GPL license of the code running in their products] Of all those efforts, two of them stood out ?
