Storage

Use case: Red Hat Storage for on-premise private cloud

Overview

Storage that scales to the cloud and beyond

Today's IT organizations are routinely expected to react quickly to changing infrastructure demands. They're increasingly turning to private cloud technology—including OpenStack®—as a way to manage scale while preserving flexibility.

OpenStack is the largest and fastest-growing open source cloud infrastructure project. To succeed, it needs scalable, flexible, next-generation storage, like Red Hat® Ceph Storage.

Ceph is the most widely deployed technology for OpenStack® because it's engineered for modern cloud architectures. Efficient, agile, and massively scalable, Red Hat® Ceph Storage significantly lowers the cost of storing enterprise information in a private cloud and helps you manage exponential data growth using standard servers and disks.

Virtual machine storage with Openstack

A better way to store VM images

If you're deploying OpenStack, you need somewhere to store virtual machine (VM) images that won't hinder you later. If you store them on the same machine as the VMs, it makes moving the VMs from server to server more difficult. It also doesn't scale with the same flexibility as OpenStack and can prevent you from realizing your project's full potential.

Red Hat Ceph Storage integrates with OpenStack services, like Nova, Cinder, Swift, Glance, and Manila, to give you more flexibility in storing images and volumes and operating at scale.

Benefits

  • Single, efficient platform

    Red Hat Ceph Storage supports all your storage needs—block (persistent and ephemeral), object, and file storage—for tenant apps in the same cluster, all in 1 platform running on standard servers and disks.

  • Streamlined setup

    With Red Hat Ceph Storage, you can set up infrastructure for both VM storage and application storage with 1 tool. And you can connect Red Hat OpenStack Platform to Red Hat Ceph Storage quickly and easily using the Red Hat OpenStack Platform director.

  • Faster VM provisioning and data backups

    Use your data more quickly by creating a copy of the disk image in place and instantly booting 1 or hundreds of new VMs right away. No need to transfer image data between storage and compute nodes—provisioning time is virtually eliminated. Activate instant backups with seamless data migration between OpenStack component services.

  • Multisite and disaster recovery options

    Expand your reach by creating a global namespace with read and write affinity to local clusters. Benefit from multisite replication for disaster recovery or archiving.

Storage for tenant applications

Scalable object storage for apps that run within VMs

For tenant apps that need to store large amounts of unstructured data, you could use OpenStack's shared object storage. But Red Hat Ceph Storage lets tenant apps store all that data in the same cluster as the VMs, using the industry-standard S3 and Swift application programming interfaces (APIs). Red Hat Ceph Storage delivers unstructured data storage for distributed, cloud-native apps.

Benefits

  • Broad ecosystem

    Take advantage of tools and applications built for legacy and emerging protocols like S3, Swift, Network File System (NFS) v3, NFS v4, iSCSI interface, as well as the growing list of Red Hat Storage software and hardware partners.

  • Easy-to-use web interface

    Gain more insight into the activity within the Ceph Storage cluster through an easy-to-use set of more than a dozen dashboards, you can monitor and, if necessary, troubleshoot the cluster by analyzing a detailed graphical view of usage data for the cluster as a whole—or its individual components.
