  • Keepalived for Linux – Keepalived is a routing software written in C. The main goal of this project is to provide simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures. Loadbalancing framework relies on well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 loadbalancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage loadbalanced server pool according their health. On the other hand high-availability is achieved by VRRP protocol. VRRP is a fundamental brick for router failover. In addition, Keepalived implements a set of hooks to the VRRP finite state machine providing low-level and high-speed protocol interactions. Keepalived frameworks can be used independently or all together to provide resilient infrastructures.
  • The BIRD Internet Routing Daemon Project – BIRD is an Internet Routing Daemon designed to avoid all of these shortcomings, to support all the routing technology used in the today's Internet or planned to be used in near future and to have a clean extensible architecture allowing new routing protocols to be incorporated easily. Among other features, BIRD supports: * both IPv4 and IPv6 protocols * multiple routing tables * the Border Gateway Protocol (BGPv4) * the Routing Information Protocol (RIPv2) * the Open Shortest Path First protocol (OSPFv2, OSPFv3) * the Router Advertisements for IPv6 hosts a virtual protocol for exchange of routes between different routing tables on a single host a command-line interface allowing on-line control and inspection of status of the daemon soft reconfiguration[…]
  • How to make MaxScale High Available with Corosync/Pacemaker | MariaDB – MaxScale, an open-source database-centric router for MySQL and MariaDB makes High Availability possible by hiding the complexity of backends and masking failures. MaxScale itself however is a single application running in a Linux box between the client application and the databases – so how do we make MaxScale High Available? This blog post shows how to quickly setup a Pacemaker/Corosync environment and configure MaxScale as a managed cluster resource.

  • FhGFS Wiki: Tips and Recommendations for Storage Server Tuning – Here are some tips and recommendations on how to improve the performance of your storage servers. As usual, the optimal settings depend on your particular hardware and usage scenarios, so you should use these settings only as a starting point for your tuning efforts.
  • Linux NAS optimizations ← BAFM – […] Well, I recently had to flatten my archive NAS (well only the OS part … *wheeeh*). Since I didn’t have the chance to backup the old settings I had to do everything from scratch … And this time I decided, I wasn’t doing a script but rather the proper way. I spent a while reading through the Internetz about the various settings until I stumbled upon a Frauenhofer Wiki entry. From there I ended up writing those udev-rules and the sysctl configs…[…]
