This tutorial describes the installation of an ISPConfig 3 multiserver setup with dedicated web, email, database and two DNS servers all managed trough a single ISPConfig 3 control panel. The setup described below uses five servers and can be extended easily to to a higher number of servers by just adding more servers. E.g.

Have you ever had a lot of data to process? In such a moment after a while of processing we realize that it will take ages to complete. It would be faster if we could use two or three or even more computers. Let's use some computers - you think it is a lot of configuration? You are wrong. With Oropo it's easy. Let's discuss a problem of processing large number of pictures.

This tutorial shows how to combine four single storage servers (running CentOS 5.4) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution).

This tutorial shows how to set up a high-availability storage with two storage servers (Fedora 12) 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 (Fedora 12 as well) will be able to access the storage as if it was a local filesystem.

This tutorial shows how to do data striping across four single storage servers (running Ubuntu 9.10) with GlusterFS. The client system (Ubuntu 9.10 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.

Small files performance is still the Achiles heel of GlusterFS. Tuning for replication (AFR, mirroring), distributed and NUFA setups is a non-trivial task, and you must know your application behaviour, your hardware and network infrastructure.
