Huawei HCSA-Sales-Storage V2.0 H19-110_V2.0 Exam Questions

Answer : D

Secondary storage acceleration is not included in Huawei's All-Flash Acceleration solution. The All-Flash Acceleration solution consists of three parts: primary storage acceleration, backup acceleration, and High-Performance Data Analytics (HPDA) acceleration. Primary storage acceleration uses OceanStor Dorado all-flash storage to deliver ultra-high performance, low latency, and high reliability for mission-critical workloads. Backup acceleration uses OceanProtect backup storage to provide fast backup and recovery for enterprise data. HPDA acceleration uses FusionCube hyper-converged infrastructure to integrate storage, computing, network, virtualization, and management into one device for edge computing scenarios.
