Introduzione a GlusterFS: uno storage scalabile e distribuito – Mia mamma usa Linux! – GlusterFS è un file system open source distribuito e scalabile orizzontalmente, la cui capacità può essere dinamicamente espansa mediante l’aggiunta di nuovi nodi. GlusterFS è in grado di arrivare a gestire fino a diversi peta byte, migliaia di client e diverse aree dati (storage) organizzandole in blocchi che rende accessibili su Infiniband RDMA (remote direct memory access, fibra ottica) o connessioni TCP/IP. Le risorse “memoria e disco” vengono rese disponibili sotto un unico punto di condivisione e tali risorse possono essere montate dai client mediante tre diversi protocolli: CIFS, NFS od il client nativo Gluster.

Debian Clusters – This site is a series of step-by-step tutorials for anyone interested in building a Debian cluster. It is geared particularly towards those interested in a Debian cluster for education or research purposes. This site is being written alongside the construction of a real Debian cluster at my institute, starting from the ground (basic networking, DHCP, DNS, authentication) up through installation a queue/scheduler and scientific software.
However, these tutorials and guides take some assumptions about users for granted, including basic Linux and Debian knowledge (see the Basic Linux Skills page for clarification and pointers to resources). This is not meant as an introduction to Debian or on how to cluster in general – thankfully, there are plenty of helpful tutorials and guides already in existence on those topics. A basic understanding of Debian and cluster technology will aid in following the tutorials.
