Red Hat Ceph Storage

Deploy a storage architecture that is massively scalable, software-defined, and ideal for the cloud

Block device storage and object gateway storage are available in a single solution. Red Hat Ceph Storage has a software-defined architecture you can integrate into your existing hardware and infrastructure for lower capital costs and more flexibility. Even better for your IT environment, Ceph Storage offers robust, multi-tenant storage for cloud and virtualization applications like Red Hat Enterprise Linux OpenStack Platform and Amazon Web Services.

Collocated containerized storage

Isolate resources for peak load and recovery situations by colocating one of the scale out daemons in each storage node, thus allowing for creation of a cluster comprised entirely of storage nodes. Because this simplified strategy reduces demand for resources and hardware costs, colocation is an ideal scenario for TCO workloads.

State of the art monitoring

Gain insight into high-level cluster health or drill-down to specific nodes to identify performance gaps with a simple, lightweight monitoring dashboard. Improve your cluster's daily operations by learning how to respond to monitoring data (in simple Q&A format) with the Ceph Management API Reference and Integration Guide.

Day one management with Ansible

Go from download to available storage quickly. Simplified deployment enables you to set up OSD, MON, and Ceph Manager nodes with an Ansible playbook on both RHEL and Ubuntu so that your cluster is immediately ready for your workloads. MDS, RGW, and the ceph client role can also be optionally deployed with Ansible.

Expanded workload reach

Migrate legacy workloads from a file-based application to an object store by using NFS v3 or v4 protocols. Platforms without a native driver (VMware and Windows) can access Ceph Storage via iSCSI, which delivers block-level access via an industry storage networking standard. Complement Ceph’s block and object storage capabilities with CephFS, which provides stability, protection from data loss, high availability, and full scale-out capabilities, such as multiple active MDS configuration.

Get Started with Red Hat Ceph Storage

To deploy Red Hat Ceph Storage 3 on Red Hat Enterprise Linux or Ubuntu, you'll need:

Installation Media

For ISO-based installations, download the ISO here.

An External Network Connection

A network connection for CDN-based installations is needed to subscribe and enable repositories hosted by Red Hat. A network connection is optional for admin nodes in ISO-based installations.

System Requirements

A minimum of six physical systems for a production system (three monitor nodes and three OSD nodes), meeting the necessary system requirements.

60 Minutes

Installing the three nodes takes about one hour.

  1. 1

    Review the Red Hat Ceph Storage 3 Hardware Selection Guide

    Avoid common hardware selection mistakes by reviewing high level guidance on selecting hardware for use with Red Hat Ceph Storage. Use the hardware guide to complete the following planning tasks:

    1. Select the performance or workload use case (high IOPS, high throughput, or low cost per TB)
    2. Select the initial scale
    3. Select the hardware
  2. 2

    Review the prerequisites

    Avoid potential deployment delays due to incomplete or insufficient environment requirements.

  3. 3

    Deploy Red Hat Ceph Storage with Ansible

    Includes all tasks needed for setting up the cluster with OSD, MON, and Ceph Manager nodes (and optionally, MDS, RGW, and the ceph client role).
  4. 4

    Verify the status of the cluster

    Run this command from a Monitor node:

    [root@monitor ~]# ceph health
