What is the minimum hardware recommendation for a single-node production installation of Tableau Server?
Tableau Server's minimum hardware recommendations for a production single-node deployment ensure reliable performance for small to medium workloads. As of the latest documentation:
CPU: 8 cores (2.0 GHz or higher) to handle concurrent users, rendering, and background tasks.
RAM: 32 GB to support in-memory processing (e.g., VizQL, Data Engine) and caching.
Disk Space: 50 GB free for installation, logs, extracts, and temporary files.
Let's break it down:
Option C (8-Core CPU, 32 GB RAM, 50 GB free disk space): Correct. This matches Tableau's official minimum for production:
8 cores ensure sufficient parallelism for processes like Backgrounder and VizQL.
32 GB RAM supports multiple users and extract refreshes.
50 GB disk space accommodates growth (initial install is ~1--2 GB, but logs and extracts expand).
Option A (4-Core, 16 GB RAM, 50 GB): Incorrect. Too low for production---4 cores and 16 GB RAM are below the threshold for reliable performance under load.
Option B (2-Core, 8 GB RAM, 15 GB): Incorrect. This is for non-production (e.g., trial) setups, insufficient for production stability.
Option D (4-Core, 64 GB RAM, 50 GB): Incorrect. 4 cores are inadequate, though 64 GB RAM exceeds the minimum (32 GB).
Why This Matters: Under-spec hardware can lead to slow performance, failed refreshes, or crashes in production---adhering to the minimum ensures stability.
