Chapter 8. Common Deployment Scenarios This section provides a brief overview of common deployment scenarios for Red Hat Satellite. Note that many variations and combinations of the following layouts are possible. 8.1. Single Location An integrated Capsule is a virtual Capsule Server that is created by default in Satellite Server during the installation process. This means Satellite Server can be used to provision directly connected hosts for Satellite deployment in a single geographical location, therefore only one physical server is needed. The base systems of isolated Capsules can be directly managed by Satellite Server, however it is not recommended to use this layout to manage other hosts in remote locations. 8.2. Single Location with Segregated Subnets Your infrastructure might require multiple isolated subnets even if Red Hat Satellite is deployed in a single geographic location. This can be achieved for example by deploying multiple Capsule Servers with DHCP and DNS services, but the recommended way is to create segregated subnets using a single Capsule. This Capsule is then used to manage hosts and compute resources in those segregated networks to ensure they only have to access the Capsule for provisioning, configuration, errata, and general management. For more information on configuring subnets see Managing Hosts . 8.3. Multiple Locations It is recommended to create at least one Capsule Server per geographic location. This practice can save bandwidth since hosts obtain content from a local Capsule Server. Synchronization of content from remote repositories is done only by the Capsule, not by each host in a location. In addition, this layout makes the provisioning infrastructure more reliable and easier to configure. See Figure 1.1, "Red Hat Satellite System Architecture" for an illustration of this approach. 8.4. Disconnected Satellite In high security environments where hosts are required to function in a closed network disconnected from the Internet, Red Hat Satellite can provision systems with the latest security updates, errata, packages and other content. In such case, Satellite Server does not have direct access to the Internet, but the layout of other infrastructure components is not affected. For information about installing Satellite Server from a disconnected network, see Installing Satellite Server in a Disconnected Network Environment . For information about upgrading a disconnected Satellite, see Upgrading a Disconnected Satellite Server in Upgrading and Updating Red Hat Satellite . There are two options for importing content to a disconnected Satellite Server: Disconnected Satellite with Content ISO - in this setup, you download ISO images with content from the Red Hat Customer Portal and extract them to Satellite Server or a local web server. The content on Satellite Server is then synchronized locally. This allows for complete network isolation of Satellite Server, however, the release frequency of content ISO images is around six weeks and not all product content is included. To see the products in your subscription for which content ISO images are available, log on to the Red Hat Customer Portal at https://access.redhat.com , navigate to Downloads > Red Hat Satellite , and click Content ISOs . For instructions on how to import content ISOs to a disconnected Satellite, see Configuring Satellite to Synchronize Content with a Local CDN Server in the Content Management Guide . Note that Content ISOs previously hosted at redhat.com for import into Satellite Server have been deprecated and will be removed in the Satellite version. Disconnected Satellite with Inter-Satellite Synchronization - in this setup, you install a connected Satellite Server and export content from it to populate a disconnected Satellite using some storage device. This allows for exporting both Red Hat provided and custom content at the frequency you choose, but requires deploying an additional server with a separate subscription. For instructions on how to configure Inter-Satellite Synchronization in Satellite, see Synchronizing Content Between Satellite Servers in Managing Content . The above methods for importing content to a disconnected Satellite Server can also be used to speed up the initial population of a connected Satellite. 8.5. Capsule with External Services You can configure a Capsule Server (integrated or standalone) to use external DNS, DHCP, or TFTP service. If you already have a server that provides these services in your environment, you can integrate it with your Satellite deployment. For information about how to configure a Capsule with external services, see Configuring Capsule Server with External Services in Installing Capsule Server .
