High-Availability Storage with GlusterFS on CentOS 7 - Mirror across two storage servers
Author: Till Brehm •
Tags: centos, high-availability, linux, storage •
Comments: 16 This tutorial shows how to set up a high-availability storage with two storage servers (CentOS 7.2) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (CentOS 7.2 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes.

Using ATA Over Ethernet (AoE) on CentOS 7 (Initiator and Target)
Author: Till Brehm •
Tags: centos, linux, storage •
Comments: 0 This guide explains how you can set up an AoE target and an AoE initiator (client), both running CentOS 7. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.

Scientific Audio Processing, Part I - How to read and write Audio files with Octave 4.0.0 on Ubuntu
Author: David Duarte •
Tags: linux, server, ubuntu •
Comments: 2 Octave, the equivalent software to Matlab in Linux, has a number of functions and commands that allow the acquisition, recording, playback and digital processing of audio signals for entertainment applications, research, medical, or any other science areas. In this tutorial, we will use Octave V4.0.0 in Ubuntu and will start reading from audio files through writing and playing signals to emulate sounds used in a wide range of activities.
