HCIE-Storage study guide
HCIE-Storage · Work through your exam, one topic at a time.
HCIE-Storage is the Expert-level credential in Huawei's Career Certification portfolio, which is organised into three levels: HCIA (Associate), HCIP (Professional) and HCIE (Expert). Storage appears as one of the technology tracks in that portfolio, alongside tracks such as Computing, Datacom, WLAN, Security, Transmission, Access, 5G and LTE. The HCIE-Storage study guide has 5 sections and about 1,966 words.
01Storage Architecture and Capacity Planning
The blueprint does not publish a fixed domain list, so these sections follow the technical areas the expert-level exam consistently tests. This one tests whether you can turn a workload profile into a defensible OceanStor design: disk-domain layout, RAID 2.0+ protection level, hot-spare policy, tier composition, and usable-capacity math.
403 words, about 2 min02SAN, NAS and Object Service Configuration
This domain tests day-2 provisioning across block, file and object on OceanStor: mapping views, initiator and host-group hygiene, multipathing and ALUA, NFS and SMB export design, and S3 bucket policy. A LUN becomes visible only through the full chain: LUN into LUN group, mapping view, port group.
418 words, about 2 min03Performance Tuning and Troubleshooting
This domain tests structured bottleneck isolation on OceanStor arrays: reading counters correctly, separating front-end, cache and back-end limits, and choosing the fix that matches the measured bottleneck rather than the loudest symptom. Establish a baseline with the workload's real I/O size and read/write mix; a 100% read synthetic test hides write-cache behaviour.
378 words, about 2 min04Data Protection and Disaster Recovery
This domain tests mapping RPO and RTO to the correct OceanStor feature and configuring it so the objective is actually met: HyperSnap, HyperClone, HyperCopy, HyperReplication, HyperMetro, and backup to OceanProtect or NDMP tape. HyperSnap: point-in-time copy in seconds, RPO in minutes.
393 words, about 2 min05Virtualization, Migration and Cloud Integration
This domain tests moving data and presenting it to hosts without downtime: heterogeneous virtualization with eDevices, SmartMigration identity takeover, cross-array migration patterns, and integration with OpenStack, Kubernetes CSI and DME. SmartVirtualization: Huawei front-end ports act as initiators to a third-party array, take over its LUNs as eDevices, and present them to hosts.
