SA satellite architecture and security

An SA satellite, rather than a full SA core, can be installed at secondary locations to enable management of remote servers. Satellites provide the same seamless management of data center servers as an SA core does. The Satellite consists of an SA Gateway and a Software Repository Cache. A Satellite Gateway provides a network connection and bandwidth management to the Satellite. A Satellite can contain multiple Gateways. The Software Repository Cache contains local copies of software packages to be installed on managed servers from the Satellite. Optionally, a Satellite can contain the OS Provisioning Boot Server and Media Server components. A Satellite must be linked to at least one Core, which may be a single core or part of a Multimaster Mesh. Multiple Satellites can be linked to a single core.

The Satellite has the following key capabilities:

  • Automate Regardless of Network Complexity: Satellites are optimized to work across low-bandwidth connections, through complex, overlapping IP address spaces, and across firewall boundaries.
  • Respond to Network Failures: SA Satellites implement sophisticated link state routing algorithms that enable dynamic routing around failed network links for redundancy.
  • Ensure Remote Server Security: Satellites enable IT organizations to proactively ensure remote server security through policy-based patch management, digitally signed and encrypted package installation, and comprehensive audit trails that track complete server change history.
