Huawei H13-629 Exam Success: HCIE-Storage (Written) Complete Study and Preparation Tips

Create a mirror LUN for a common LUN. Due to internal information exchange, the LUN ID for hosts’ read and write I/Os changes based on the information exchange result.

A LUN stores 2 GB of data. Create a mirror LUN for this LUN. During the creation, the system automatically generates a copy. The total data amount of the copy and mirror LUN is 4 GB.

HyperMirror can be configured for external LUNs, and external LUNs can be configured as HyperMirror copies.

When configuring HyperMirror, its copies must come from different disk domains.

The equipment in the picture has completed the equipment preparation step

The corresponding LUN in the figure is a LUN created on the service hard disk of the engine

Change the equipment status is normal

The process of preparing a physical device is the process of virtualizing a LUN mapped from an array, similar to a quick format

Source LUNs: 1 and 3Target LUNs: 2 and 4

Source LUNs: 1 and 4Target LUNs: 3 and 3

Source LUNs: 3 and 1Target LUNs: 4 and 2

Source LUNs: 2 and4Target LUNs: 1 and 3

True

False

The local storage system does not occupy the local storage system when using LUNs in heterogeneous storage systems

For external LUNs, the local storage system can set value-added functions such as remote replication, snapshots, etc.

smartVirtualization uses multipathing software to connect heterogeneous storage in a multipath-redundant manner

smartVirtualization Dictate write data write efficiency is higher than the write-back efficiency

Locate the exterior first, then the interior

First perform an alarm analysis, then use the replacement method

First find the high-level alarm, then the low-level alarm

Find the common first alarm, after the individual alarm

When the file is locked, the file protection time can be extended or shortened by manual operation

Locked file system WORM clock is greater than the file atime value, the file will be in an expired state

When the file is in an append state, afterthe legal clock of the WORM file system exceeds the file expiration time, the file is movedMoved to expired status

When the size of the file is 0 bytes, the lock state can be migrated to the additional state

scale-out: storage resources on-demand expansion, increase the engine to achieve performance, linear increase incapacity

Full Exchange: The use of PCIE1.0 full switching interconnect, providing sufficient switching bandwidth to meet the stringent performance requirements

Inherent Load Balancing: The controller is alive and well-balanced load sharing to improve storage resource utilization

Full redundancy: Redundancy of all components, intelligent switchover of component failures to meet stringent business continuity requirements
