QRadar Architecture and Installation Resources
IBM® QRadar® architecture supports deployments of varying sizes and topologies, from a single host deployment, where all the software components run on a single system, to multiple hosts, where appliances such as Event Collectors, and Flow Collectors, Data Nodes, an App Host, Event Processors, and Flow Processors, have specific roles.
Managed Host Resources
A distributed IBM Security QRadar deployment is comprised of a Console and a number of managed hosts. Managed hosts are non-Console QRadar appliances that provide greater flexibility over data collection and event and flow processing.

Fix Packs (SFS Files)
The most common software update scenario for administrators is to install a QRadar fix pack update. Fix packs resolve known issues and normally do not contain features or major operating system changes. Fix Packs update the F in IBM’s V.R.M.F software deliveries.

Fix Pack Notes
Run drq health checks before you begin any upgrade. QRadar Support instructs administrators to stay updated and apply Fix Packs when available. Fix Packs are typically released on 8 to 12 week cycles for supported software versions as indicated by the QRadar Software Lifecycle.
Upgrades (ISO Files)
Upgrades are major release updates, delivered as an ISO file to add new features, operating system (OS) updates, and resolve issues as part of the installation. An upgrade generally increment the modification (M) numeric indicator for IBM V.R.M software deliveries.

Upgrade notes
Administrators might be required during major updates to install an ISO, then apply a Fix Pack to update a deployment to the latest software version. IBM does not release ISO files with every Fix Pack version. Administrators should review the Upgrade Guide to determine if VMs meet suggested memory requirements as new features can consume more resources over time.
