Log analysis tools can run on any PC, do not need to interoperate with the storage system, the analysis process time according to the amount of the log may be, may it takes a long time

Log Analysis Tools After starting the analysis, the analysis tasks need to be stopped due to other reasons. Click on the analysis tool to abort this analysis

Engineer A deleted the original compression of the results of the collection, then the results will be collected to re-catalog the contents of all documents compressed into zip format for the dayChi analysis tools for analysis

After the analysis is completed, all the problems caused by the log analysis will be presented in the list of problems, and "View Details" contains the approximate cause of the problem and processing advice

Question # 63

True or False, all OceanStor Unified Storage Array disks have the ability to store dirty data after a sudden power failure

True

False

Question # 64

Which of the following are correct regarding a Storage Array RAID 2.0 Typical Application Performance Tuning? (multiple choice)

Scenario: Sequencing large IO services, especially 1M IO scenarios, with the phenomenon that the back-end read bandwidth is much larger than the front-end read bandwidthTuning: Turn off the corresponding LUN prefetch policy

scene: the order of pressure reading and writing business conditions, high utilization of hard drivesTuning means: increase the unplug-thresh device hard disk device

Scenario: Oracle database in the operation of data backup, the data on the LUN bandwidth does not meet the requirements and accompanied by high utilization of hard diskTuning means: the formal creation of POOL to increase the depth of the points

Scenario: In the case of single concurrent or low concurrent read service, the delay is found to be largeTuning means: change disk unplug 8 Modify unplug - thresh increased from 4 to 8

Question # 65

True of False, N8500 volume mirroring function synchronization can be understood as a file system to do RAID 1 to achieve image protection This protection is done in two ways:

One Species is the mirror roll between showrooms, the display level of protection, a display failure, the business is not affected; the other is the mirror image display within the exhibition.

RAID level protection, a RAID group failure, the business will not be affected.

True

False

Question # 66

True

False

Question # 67

The OceanStor 18500 uses the RAID 2.0 virtualization architecture. When planning to configure storage, which of the following is incorrect?

A storage pool can create two types of LUNs, Thick LUN and Thin LUN

When creating a storage pool, the minimum number of SAS disks in the hard disk domain where the storage pool is located is 9 disks when the performance layer RAID policy is selected as 8D + 1P

In the RAID 2.0 virtualization architecture, the hot spare space in the storage pool is distributed on each member disk in the storage pool

RAID 2.0 virtualization architecture, the storage pool can contain three storage tiers, and each tier can be configured with a number of different RAID strategies

Question # 68

Set up two data centers in the same city to form a dual disaster recovery network

Set up a data center in the local and remote sites to form a dual-active disaster recovery network

In the same city set up two data centers to do double live in another remote data center to do asynchronous remote replication

Question # 69
