In fact, at the operational layer we can have as many datazones as is required by the business, all subordinate to the unified Enterprise Layer. Operational LayerĪt the operational layer we have what is defined as a NetWorker datazone. This allows centralised reporting, management and control for backup administrators and operators. While you could, if you wanted to, deploy a NMC Server for each NetWorker Server, it’s by no means necessary, and so it’s reasonably common to see a single NMC Server deployed across multiple NetWorker servers. The functional load of providing GUI services does not impact the core Server functionality (i.e., providing backup and recovery services).The GUI can be used to administer multiple servers.The GUI and the Server functionality can be developed with more agility.This has multiple architectural advantages, such as: Like many applications, NetWorker has separated the GUI management from the core software functionality. This is a very light-weight server, and it’s quite common to the license services run concurrently on the same host as the NMC Server. The License server can be used by a single NetWorker server, or if you’ve got multiple NetWorker servers, by each NetWorker server in your environment, allowing all licenses to be registered against a single host, reducing ‘relicensing’ requirements if NetWorker server details change, etc. The key services that will typically be run within the Enterprise Layer are the NetWorker License Server, and the NetWorker Management Console Server (NMC Server). While NetWorker has previously had the option of running an independent license server, with NetWorker 9 this has been formalised, and the recommendation is now to run a single license server for all NetWorker environments within your business, unless network or security rules prevent this. The Enterprise Layer consists of the components that technically sit ‘above’ any individual NetWorker install within your environment, and can be depicted simply with the following diagram: In theory an entire NetWorker environment can be collapsed down to a single host – the NetWorker server, backing up to itself – but in practice we will typically see multiple hosts in an overall NetWorker environment, and as has been demonstrated by the regular NetWorker Usage Surveys, it’s not uncommon nowadays to see two or more NetWorker servers deployed in a business. There are two distinct layers of architecture I’ll cover off – Enterprise and Operational. With the NetWorker 9 architecture now almost 12 months old, I thought it was long past time I do a Basics post covering how the overall revised architecture for data protection with NetWorker functions.
