This course is based on Red Hat Ceph Storage 3.0, Red Hat Enterprise Linux 7.4/7.5, and Red Hat OpenStack Platform 10.0.
Red Hat Ceph Storage Architecture and Administration (CEPH125) helps you provide unified storage for enterprise servers and Red Hat® OpenStack Platform with Red Hat Ceph Storage. Learn to use a Ceph storage cluster to provide servers and cloud resources with object storage compatible with the Amazon S3 or OpenStack Swift APIs, Ceph-native or iSCSI-based block storage, and file storage using CephFS.
This course is intended for storage administrators, cloud operators, and cloud developers who want to learn how to deploy and manage Red Hat Ceph Storage for use by servers in an enterprise data center or within a Red Hat OpenStack Platform environment.
- Be certified as a Red Hat Certified System Administrator (RHCSA), or demonstrate equivalent experience
- Some experience with storage administration is recommended, but not required
Impact on the organization
This course is intended to develop the skills needed to deploy a software-defined storage system on commodity hardware, permitting distributed, scalable, fault-tolerant object, block, and file data storage. Such a deployment provides a storage infrastructure that can grow at the same pace as your compute infrastructure, allowing a gradual investment to accommodate business growth.
Impact on the individual
As a result of attending this course, you should be able to deploy and operate a Red Hat Ceph Storage cluster and configure it as backend storage for Red Hat OpenStack Platform. You should be able to demonstrate these skills:
- Explain the architecture of a Ceph cluster.
- Deploy a Red Hat Ceph Storage cluster using Ansible.
- Manage operations on a Red Hat Ceph Storage cluster.
- Provide servers with storage from the Ceph cluster using block, object, and file-based access methods.
- Integrate Red Hat Ceph Storage as backend storage for Red Hat OpenStack Platform.
- Prepare for Red Hat Ceph Storage
- Deploy Red Hat Ceph Storage
- Configure Red Hat Ceph Storage
- Provide block storage with RBD
- Provide object storage with RADOSGW
- Provide file storage with CephFS
- Configure the CRUSH map
- Manage and update the cluster maps
- Manage a Red Hat Ceph Storage cluster
- Tune and troubleshoot Red Hat Ceph Storage
- Integrate Red Hat Ceph Storage with OpenStack
Prepare for Red Hat Ceph Storage
- Identify challenges faced by traditional storage and explain how Ceph addresses them.
Deploy Red Hat Ceph Storage
- Deploy and expand the storage capacity of a new Red Hat Ceph Storage cluster.
Configure Red Hat Ceph Storage
- Manage how Ceph stores data with pools, configure Red Hat Ceph Storage using its configuration file, and configure users for Ceph clients that may access the Ceph storage cluster.
Provide block storage with RBD
- Configure Ceph to provide block storage for clients by using RADOS block devices (RBDs).
Provide object storage with RADOSGW
- Configure Ceph to provide object storage for clients by using a RADOS gateway (RADOSGW or RGW).
Provide file storage with CephFS
- Configure Ceph to provide file storage for clients using the Ceph Filesystem (CephFS).
Configure the CRUSH map
- Adjust the CRUSH map—which controls how data is stored, replicated, and distributed across OSDs in the Ceph cluster—in order to optimize resiliency and performance.
Manage and update the cluster maps
- Explain how the monitor and OSD maps are managed in order to maintain cluster operation, quorum, and consistency.
Manage a Red Hat Ceph Storage cluster
- Check Ceph cluster status, troubleshoot Ceph daemon problems, and upgrade Ceph software.
Tune and troubleshoot Red Hat Ceph Storage
- Identify the key performance metrics for a Ceph cluster and use them to help tune and troubleshoot the operating system and Ceph software for optimal performance.
Integrate Red Hat Ceph Storage with OpenStack
- Configure an OpenStack cloud to use Ceph to provide image, block, object, and file storage.
