Huawei Storage Pool Single Tier Capability
Short answer
A Storage pools can be created with a single tier of disks, making the statement false.
Question
Key Takeaways
The trap assumes that advanced features like SmartTier necessitate mixed tiers, but basic pool creation allows homogeneous disk sets.
This question addresses whether Huawei storage pools support single-tier disk configurations. The correct answer is False, as pools can be formed from a single type of disk.
Common mistake: Choosing TRUE because users confuse the capability of SmartTier (which uses multiple tiers) with the fundamental requirement for creating any storage pool.
Expert Analysis
The statement claims that storage pools cannot be created with a single tier of disks. This is FALSE.
In Huawei OceanStor V3 and subsequent storage systems, a Storage Pool is the fundamental unit for resource management. It aggregates physical disks (DVs) to provide logical capacity. The system supports various disk types and tiers within a pool, but it does not require multiple tiers to function. A storage pool can indeed be composed of a single tier of disks (e.g., all SSDs or all HDDs). While multi-tier storage (combining SSDs and HDDs) is a feature for performance optimization (SmartTier), it is not a prerequisite for creating the pool itself. Single-tier pools are common in environments with homogeneous disk requirements.
Therefore, the restriction described in the question does not exist. The correct answer is FALSE.
Exam Strategy
When evaluating statements about storage capabilities, distinguish between optional advanced features (like tiering) and mandatory base requirements. If a feature is labeled 'advanced' or 'optimization,' it rarely restricts basic functionality unless explicitly stated as 'only'.
