A cluster is a group of storage servers that work together as a single volume. Within an individual server, you can combine drives in numerous ways to create volumes. With clustering, you install and configure cluster software on top of each server, thus combining them to create a single storage space with larger aggregate capacity, or trading off some of your raw capacity for robustness via redundancy.

Our cluster example is made up of:


Our Storinator storage server is an open storage platform that gives you the freedom to run any software you choose including GlusterFS, Ceph, and MooseFS. Our clusters are using servers that run CentOS with GlusterFS and ZFS on Linux running on top, to create one central storage platform. We have many customers using other Linux distros, such as Debian, FreeBSD, and RedHat, but in our petabyte configuration we used the following:

How to achieve petabytes of data with a cluster using GlusterFS

A cluster is a group of storage servers that work together as a single volume. Depending on how you configure your cluster, you can achieve different goals, such as large aggregate capacity or robustness via redundancy. To create a cluster, one adds a software layer on top of the OS that runs each server. A little bit of configuration, and you are up and running.
