Huawei HCIP-Storage study plan

Trace the end-to-end read and write I/O path from host application through file system or volume manager, front-end port, controller cache, back-end loop, and physical disk, and annotate at each hop what fails if that component degrades.

Compare RAID 0/1/5/6/10 and Huawei RAID-TP on capacity overhead, rebuild cost, write penalty, and tolerated failures, choosing the right level for OLTP, video surveillance, and archive workloads.

Explain controller cache mechanics - write-back versus write-through, cache mirroring between controllers, battery or supercapacitor protection, and cache pre-fetch - and predict behavior when the cache is bypassed.

Distinguish HDD, SAS/SATA SSD, NVMe SSD, and SCM media on latency, endurance, and cost per IOPS, and describe how automatic tiering moves data between them.

Describe scale-up versus scale-out storage architectures and state which Huawei product family follows each model.

Map the OceanStor portfolio - Dorado all-flash, OceanStor V6 hybrid, OceanStor Pacific scale-out, and object storage - to typical customer scenarios based on protocol, performance, and capacity needs.

Explain how an all-flash array differs from a hybrid array in garbage collection, wear leveling, and inline compression/dedup, and when dedup should stay off.

Identify controller, enclosure, fan, power, and interface module components on a typical midrange array and state which are redundant on the data path.

Position OceanStor Dorado against OceanStor V6 on latency, NVMe support, and target workloads, and justify a purchase recommendation for two contrasting customer briefs.

Describe OceanStor Pacific capabilities - file, object, and HDFS access on one namespace, scale-out expansion - and explain how it differs from a conventional NAS in scaling behavior.

Outline OceanProtect backup storage and its role in backup, archiving, and ransomware-resistant copies.

Size a storage system from a workload profile: given IOPS, capacity, growth rate, and RAID overhead, calculate usable capacity and the number of controllers or enclosures required.

Compare FC, iSCSI, NFS, SMB/CIFS, and NVMe over Fabrics on transport, typical latency, and configuration prerequisites, and select the right one for block database, VMware, and media-editing scenarios.

Design an FC SAN: explain fabric login, WWN and NPIV, single-initiator single-target zoning rules, and why zone changes are done during a maintenance window.

Configure and validate host-side multipathing using UltraPath or native MPIO, describing ALUA path states and how failover and failback actually occur.

Secure and tune IP-based access by applying CHAP authentication, VLAN separation, jumbo frames, and link aggregation, and explain the risk each control addresses.

Distinguish snapshot, clone, and remote replication on copy semantics, space consumption, and RPO, and pick the right one for accidental deletion, patch rollback, and site loss.

Explain HyperMetro active-active for block and file, including quorum server role and what happens to I/O when the inter-site link or one site fails.

Explain synchronous versus asynchronous HyperReplication, including how the cycle period drives RPO and bandwidth sizing.

Describe the three-data-center chain and parallel topologies and state which failure combinations each one survives.

Build a backup policy - full versus incremental, retention generations, offsite copy, and restore testing cadence - and defend the chosen RPO and RTO against a business requirement.

Explain ransomware protection mechanisms such as immutable copies, air-gapped or offline copies, and safe snapshots, and state which one stops a compromised admin account.

Read a replication or HyperMetro state from the management GUI and diagnose a split-brain, link-down, or high-latency condition using the reported status and logs.

Calculate replication bandwidth and buffer requirements from change rate, link capacity, and peak window.

Navigate device management, alarm, performance, and log collection functions, and describe which tool to open for a capacity alarm versus a host latency complaint.

Interpret performance counters - IOPS, bandwidth, latency, queue depth, cache hit ratio, and port utilization - to locate whether a bottleneck is host, fabric, front-end, back-end, or disk.

Troubleshoot a LUN not visible to a host by working through zoning, masking, multipath, host OS rescan, and file system mount in a fixed order.

Collect and hand off a diagnostic bundle: state which logs, at what time window, and why timestamps across host, switch, and array must be correlated.

Re-run missed questions from every earlier self-quiz and close each gap by re-reading the specific source section rather than the whole chapter.

Complete a timed 60-question mixed mock exam across all five domains and score each domain separately to expose weakest areas.

Recite from memory the key facts sheet: RAID-TP parity count, HyperMetro quorum rules, replication mode differences, zoning rules, and standard troubleshooting order.

Explain, in a five-minute verbal walkthrough, one full solution from host connectivity through protection, as if presenting to a customer.
