Simplify system management

Wish you could manage tens, hundreds, even thousands of Red Hat® Enterprise Linux® servers as easily as 1?

Red Hat Satellite is built on open standards and based on functional modules that let you enhance management capabilities for Red Hat Enterprise Linux on virtualized or bare-metal deployments.

Questions and answers

General product

While you can do basic administrative tasks with the Red Hat services included with your Red Hat Enterprise Linux subscription, Red Hat Satellite adds extensive life-cycle management capabilities, including:

  • Patching
  • Subscription management
  • Provisioning
  • Configuration management

From a single console you can easily manage thousands of systems as easily as 1, which can help increase system availability, reliability, and auditability. These management capabilities are often needed by organizations with growing Red Hat Enterprise Linux environments.

Red Hat Satellite is a systems management solution that makes Red Hat infrastructure easier to deploy, scale, and manage across physical, virtual, and cloud environments. Satellite enables users to provision, configure, and update systems to help ensure that they are running efficiently, securely, and compliant with various standards. By automating most tasks related to maintaining systems, Satellite helps organizations increase efficiency, reduces operational costs, and enables IT to better respond to strategic business needs.

The Red Hat Satellite Capsule Server is used to extend the management of Red Hat Satellite to remote datacenters. Typically a Red Hat Satellite Capsule Server instance is deployed in each remote datacenter to federate services like provisioning so they can be performed locally. It’s focused on providing a local repository of certified content for Red Hat Enterprise Linux. This model extends Red Hat Satellite to deliver updates, errata, and software in a highly scalable fashion while using less network bandwidth. Red Hat Satellite Capsule Server replaces Red Hat Satellite Proxy.

Red Hat Satellite is now available for download on the Red Hat Customer Portal as part of your Red Hat Satellite subscription.

This documentation is available in the Red Hat Customer Portal, along with the documentation for all Red Hat Satellite releases.

Bare metal, Red Hat Enterprise Virtualization, Red Hat Enterprise Linux OpenStack® Platform, VMWare, and Amazon EC2.

Key projects include Foreman, Puppet, Katello, Pulp, and Candlepin.

The product architectures between Red Hat Satellite 5 and Red Hat Satellite 6 are very different. Red Hat Satellite 6.x requires a fresh install, so upgrading in place from Red Hat Satellite 5.x to Red Hat Satellite 6.x is not possible. Current Red Hat Satellite 5 customers will have many options to manage their Red Hat Enterprise Linux environment with Red Hat Satellite 6. Visit the Red Hat Satellite page on the Customer Portal for more information.

Red Hat Satellite versions 5.5 and earlier are no longer supported. Red Hat Satellite 5.6 and above exit Production Phase 3 support on January 31 2019, at which time only Satellite 5.8 will be supported until May 31, 2020. It is critical to note that RHN (Red Hat Network) is shutting down on January 31, 2019. At that point, only Satellite 5.8 will be able to receive new content through RHSM (Red Hat Subscription Manager). Refer to Satellite’s life cycle support page for more information.

Security

You can download content from the Red Hat Content Delivery Network (CDN) to a staging system and store it on physical media so that your organization can keep certified content up to date. Many organizations that have tight security requirements use the disconnected Red Hat Satellite configuration.

From a features perspective, Red Hat Satellite lets administrators implement a full audit trail of all activities taken through Red Hat Satellite and assign policies and permissions for simple role-based administration.

Interoperability and customization

You can use the application programming interface (API) in Red Hat Satellite to script commands inside the product and to exchange information with other management products. Customers have used the API in Red Hat Satellite to integrate it with other management tools from vendors like HP and IBM.

There should be at least 1 networked host with the following minimum specifications:

  • 64-bit architecture.
  • The latest version of Red Hat Enterprise Linux 6 Server or 7 Server is required, but Red Hat Enterprise Linux is recommended.
  • A minimum of 2 CPU cores, but 4 CPU cores are recommended.
  • A minimum of 12 GB memory is required for the Satellite Server to function, 16 GB of memory or more is recommended for each instance of Satellite Server. In addition, a minimum of 4 GB of swap space is also recommended. Satellite running with less memory than the minimum value may not operate correctly.
  • A unique host name, which can contain lower-case letters, numbers, dots (.) and hyphens (-).
  • A current Red Hat Satellite subscription.
  • Administrative user (root) access.
  • A system umask of 0022.
  • Full forward and reverse DNS resolution using a fully-qualified domain name.
  • See the Red Hat Satellite installation guide for storage recommendations and the most current specifications.

Note: The Red Hat Satellite Server and Capsule Server versions must match. For example, a Satellite 6.1 Server cannot run a 6.2 Capsule Server and a Satellite 6.2 Server cannot run a 6.1 Capsule Server. Mismatching Satellite Server and Capsule Server versions results in the Capsule Server failing silently.

Red Hat Satellite 6 includes an embedded PostgreSQL database.

Yes. Red Hat Global Professional Services offers consulting services specifically for Red Hat Satellite customers. Contact Red Hat Sales for more information.

Red Hat is currently offering a 30-day trial evaluation. Contact a Red Hat sales representative for details.

For the Smart Management Add-On entitlements, customers get the same service-level agreement (SLA) as they currently subscribe to for the operating system. The Red Hat Satellite Server and Red Hat Satellite Capsule Server models include a subscription to Red Hat Enterprise Linux premium, which ensures that customers receive Red Hat premium support.

Virtualization support

Red Hat Satellite can manage any system running Red Hat Enterprise Linux on any supported hypervisor, including Red Hat Virtualization and VMware. To do this, each Red Hat Enterprise Linux system managed by Red Hat Satellite must have the necessary Smart Management Add-On entitlement.

Red Hat Satellite and Red Hat Satellite Capsule Server are currently supported on Red Hat Enterprise Linux guests hosted by supported hypervisors, like Xen, KVM, and VMware hypervisors.
