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.
