Hardware minimums for CPU, RAM and disk
Separate Tableau Server's blocking installation minimums from its production recommendations for processor, CPU cores, RAM and free disk on version 2022.3, count cores the way Setup does, and size disk for extracts, refreshes, logs, backups and restores.
1.4 Minimum Hardware Requirements: 1.4.1 Understand: 1.4.1.1 RAM requirements, 1.4.1.2 CPU requirements, 1.4.1.3 Hard disk requirements.
~7 min read · 7 practice questions
What the exam expects
- State the RAM installation minimum and production recommendation for Tableau Server 2022.3, by node type.
- State the CPU installation minimum and production recommendation, including which processors qualify and how cores are counted.
- State the free disk installation minimum and production recommendation, and when free space is measured.
- Plan disk beyond the minimum for extracts, refreshes, logs, backups and restores.
Key terms:
- Installation minimum: the hardware below which Setup will not install Tableau Server.
- Production recommendation: the hardware most production nodes should meet; Setup only warns when it is missing.
- Physical core: a real core on hardware or a VM; hyper-threaded logical processors are not counted.
- Initial node: the first node of an installation; its RAM minimum differs from additional nodes in a cluster.
- Temp directory: where an extract is written during a refresh.
