RAID 0 uses striping, not mirroring, and does not provide redundancy or data protection.
Question 67
Which features can improve system performance in SAN storage? (Select all that apply)
Correct Answer: A,D
In Huawei OceanStor Hybrid Flash systems, performance optimization is achieved through intelligent resource management. Level-2 cache (Option A), known as SmartCache, utilizes SSDs as an extension of the system's DRAM cache. By storing "hot" data on high-speed SSDs, the system significantly reduces the read latency for frequently accessed blocks that have been evicted from the primary memory cache. Storage tiering (Option D), or SmartTier, automatically migrates data blocks between different storage tiers (SSD, SAS, and NL-SAS) based on their access frequency. It ensures that active data resides on the highest-performance media while moving inactive "cold" data to high-capacity drives. These two features are specifically designed to maximize IOPS and minimize response times. In contrast, Thin Provisioning (SmartThin) and Data Deduplication (SmartDedupe) are "Storage Efficiency" features; their primary goal is to save physical space and improve capacity utilization. While essential for TCO, they do not inherently improve raw system performance and may involve a minor metadata overhead during processing.
Question 68
What are the competitive advantages of the Hyper CDP feature, as supported by the Dorado V3?
Correct Answer: A,B
Question 69
SmartTier for file systems is a tiering feature. What is the migration granularity?
Correct Answer: C
Question 70
Which of the following encryption modes is used by the ransomware protection solution of the new-gen OceanStor hybrid flash storage for encryption at the transport layer?
Correct Answer: D
Replication link encryption is used by the ransomware protection solution of the new-gen OceanStor hybrid flash storage to secure data during transmission at the transport layer, ensuring data confidentiality and integrity between storage systems.
