HUAWEI OceanStor V3 SmartTier Tiers and Limits
Short answer
D Statement 1 is false because SSDs reside in the High-Performance Tier, while Statement 2 is true as OceanStor V3 supports a maximum of 3 tiers.
Question
Statement 1: With the SmartTier feature the SSD disks are in the Performance Tier.
Statement 2: No more than 3 tiers can exist in the OceanStor V3 storage arrays.
Key Takeaways
The main trap is confusing the 'Performance Tier' (SAS) with the 'High-Performance Tier' (SSD), leading candidates to incorrectly mark Statement 1 as true.
Learn why Statement 1 is false and Statement 2 is true regarding HUAWEI OceanStor V3 SmartTier configuration, specifically SSD placement and tier limits.
Common mistake: Option A is a common mistake. Candidates often believe SSDs are in the Performance Tier (making Stmt 1 true) but correctly identify the 3-tier limit (making Stmt 2 true), failing to see that SSDs actually define the highest tier.
Expert Analysis
SmartTier Tier Mapping
In Huawei OceanStor V3 systems, the SmartTier feature automatically migrates data across tiers based on access frequency. The architecture defines specific disk types for each tier: Solid State Drives (SSDs) are assigned to the High-Performance Tier, not the Performance Tier. The Performance Tier is reserved for SAS disks, while Nearline SAS (NL-SAS) disks constitute the Capacity Tier. Therefore, Statement 1 is false because it incorrectly places SSDs in the Performance Tier.
Maximum Tier Count
The OceanStor V3 storage arrays support a maximum of three tiers: High-Performance, Performance, and Capacity. This aligns with the hardware capabilities and the SmartTier policy limits. Consequently, Statement 2 is true, as there cannot be more than 3 tiers in this specific array model.
Conclusion
Statement 1 is false (SSDs belong to the High-Performance Tier). Statement 2 is true (maximum 3 tiers exist). Thus, Option D is the correct choice.

Exam Strategy
When answering questions about tiered storage, always verify the specific disk technology assigned to each tier name. Memorize the hierarchy: SSD = High-Performance, SAS = Performance, NL-SAS = Capacity. Do not assume 'Performance' implies the fastest tier; check the vendor's specific naming convention.

Dhedy_Sasax 👍 1 Answered D- SSD Shoul be on High-Performance Tier and for performance used SAS Disk - There are 3 tier : High-Performence (SSD), Performance (SAS), Capacity performance (NL-SAS) https://support.huawei.com/enterprise/en/doc/EDOC1100038384/8c5e1590/working-principle
