Explanation
256 TB (option C) is the maximum supported file system size on Dell PowerStore, as defined in the platform's official storage architecture specifications.
- A (512 TB) is incorrect - this exceeds the platform's current per-filesystem ceiling and may be confused with aggregate pool capacity or future roadmap figures.
- B (64 TB) is incorrect - this is too conservative and does not reflect PowerStore's scale-out capabilities.
- D (128 TB) is incorrect - while plausible, it represents roughly half the actual supported limit and may stem from confusing file system limits with other per-volume constraints on different Dell platforms.
Memory tip: Think "256 = 2⁸" - PowerStore file systems max out at a power-of-two value in the 256 TB range, which mirrors common binary scaling patterns in enterprise storage. If you can remember the number is a power of 2 between 128 and 512, you land on 256.
