The LUN of the entire series of flash memory products supports Active-Active access, the business is evenly distributed on the front-end link, and the LUN belongs to a specific controller, which is easy to use.
- A . True
- B . False
Huawei OceanProtect backup appliance is widely used by customers in many industries because it adopts the design of CPU Core grouping + intelligent scheduling key technology. Which of the following is an advantage of this technology?
- A . This technology can achieve physical and logical isolation of resources and reduce latency
- B . The system can pre-fetch data and metadata of all LUNs to improve cache hit rate
- C . The scheduler can distribute tasks to other cores according to the business load status to achieve load balancing
- D . This technology has the problem of overloading some cores when carrying different services, resulting in high latency
A financial customer purchased two Huawei flash storages for subsequent business deployment. Engineers are now creating a storage pool on the storage system and need to specify a redundancy strategy during creation.
Which of the following analyses of storage pool redundancy policies are wrong? (Multiple choice)
- A . Engineers can only configure RAID6 and RAID-TP in the storage pool for creating chassis-level redundancy. If a storage pool configured with RAID6 has a failed disk that has not been rebuilt, other disk chassis will not be allowed to fail until the failed disk is rebuilt.
- B . Engineers only support setting chassis-level redundancy policies when creating a new storage pool. After the storage pool is created, it does not support modifying the attributes of the chassis-level redundancy policy.
- C . Disk-level redundancy requires that the CKs that make up the CKG not only come from different hard disks, but also be distributed in different frames, and the number of CK columns from each frame does not exceed the RAID redundancy.
- D . When engineers create a storage pool with a chassis-level redundancy policy, the hard disks that make up the storage pool must be planned to come from at least four chassis (controller chassis + hard disk chassis), and each chassis must be configured with at least three hard disks.
A financial customer purchased a Huawei all-flash storage for business deployment. During daily storage use, the administrator found that the performance of the storage had large fluctuations, and then conducted relevant inspections on the performance issues.
Which of the following is not a check item that needs to be done for performance fluctuation issues?
- A . Check whether there are obvious storage background tasks at the fluctuation time point, such as data reconstruction, etc.
- B . Check whether there are any abnormal SmartKit operations during the fluctuation period
- C . Check whether there is an obvious hit rate mutation at the fluctuation time point
- D . Check whether there are obvious hardware resource bottlenecks on the storage side at the fluctuation time point
To ensure data consistency at active-active sites, Huawei’s all-flash storage HyperNetro uses a () lock mechanism. This mechanism does not require a lock server across sites, reducing the complexity of the architecture.
If the user needs to configure the connection between the storage system and the DNS server, which of the following prerequisites must be met before the configuration? (Multiple choice)
- A . TCP/UDP port 443 and port 8890 need to be opened between the storage system and the DNS server.
- B . The network latency between the storage system and the DNS server needs to be less than or equal to the configured latency
- C . The DNS server has been configured and is running normally
- D . TCP/UDP port 53 between the storage system and the DNS server needs to be opened
In actual business scenarios, the active-active system of Huawei’s OceanStorPacific series products can support incremental synchronization. When a site fails, the site that wins the arbitration will provide services according to the arbitration mechanism, and IO requests will be converted from dual write to single write. When the failed site recovers the system, it can support the ability to synchronize the data of the failure process to the recovery site.
- A . True
- B . False
When optimizing the storage layer performance of Huawei flash storage, cache-related policies and configurations will be involved.
Which of the following descriptions about cache high and low water levels is wrong?
- A . Generally, the high water mark in the cache should not be too high, and the distance between the high and low water marks should not be too small.
- B . If the high water mark in the cache is set too high, it will affect the write performance. If the low water mark is set too low, it will affect the read performance.
- C . Normally, the low water mark for storing dirty data in the cache should not be too low. 20% is generally recommended.
- D . If the cache high water mark is set too high, when the front-end I/O traffic increases suddenly, I/O fluctuations and increased latency will usually occur.
When modifying the management network port IP address of Huawei flash storage, the management network port IP address and the maintenance network port IP address cannot be in the same network segment, otherwise it will cause routing conflicts.
- A . True
- B . False
To ensure the correct and smooth installation of storage system equipment, it is necessary to check whether the required installation auxiliary materials are ready before installation, including installation auxiliary tools, instruments, software tools and data.
- A . True
- B . False
