Part I. Installation

Designed for cloud infrastructures and web-scale object storage, Red Hat® Ceph Storage is a massively scalable, open, software-defined storage platform that combines the most stable version of Ceph with a Ceph management platform, deployment tools, and support services. Providing the tools to flexibly and cost-effectively manage petabyte-scale data deployments in the enterprise, Red Hat Ceph Storage manages cloud data so enterprises can focus on managing their businesses.

This document provides procedures for installing Red Hat Ceph Storage v1.2.3 for x86_64 architecture on Red Hat Enterprise Linux (RHEL) 6 and RHEL 7.

To simplify installation and to support deployment scenarios where security measures preclude direct Internet access, Red Hat Ceph Storage v1.2.3 is installed from a single software build delivered as an ISO with the ice_setup package, which installs the ice_setup script. When you execute the ice_setup script, it will install a local repository, the Calamari monitoring and administration server and the Ceph installation scripts, including a cephdeploy.conf file pointing ceph-deploy to the local repository.

We expect that you will have a dedicated administration node that will host the local repository and the Calamari monitoring and administration server. The following instructions assume you will install (or update) the repository on the dedicated administration node.

The administration/Calamari server hardware requirements vary with the size of your cluster. A minimum recommended hardware configuration for a Calamari server includes at least 4GB of RAM, a dual core CPU on x86_64 architecture and enough network throughput to handle communication with Ceph hosts. The hardware requirements scale linearly with the number of Ceph servers, so if you intend to run a fairly large cluster, ensure that you have enough RAM, processing power and network throughput.
