The backup back-end capacity is determined by the initial capacity and data increment.

In Huawei's distributed storage, the block service asynchronous remote replication architecture is based on the block service cluster to build an asynchronous replication relationship. Based on the difference data, the data of the master and slave volumes are periodically synchronized. After the data synchronization in the last synchronization cycle is completed, all the data generated on the master volume will be written to the slave volume during the current synchronization cycle until the current synchronization cycle begins.

During the processing of Huawei's distributed storage block service IO stack, the block service of the node that writes the request to EDS writes data into the cache, and the read request has a hit in the current index. If it does not hit, it reads and writes from the cache.

A snapshot copy is a technique for backing up the moment of activation of a snapshot, which contains the private data of the snapshot after activation.

Which of the following statements about distributed storage is correct? (Multiple Choice)

Divide a LUN by 9000, map it to the operating system and mount a dedicated file system, and use the test tool to write a large number of 13K files. In order to improve the IO performance, it is recommended to set the read size to 16K.

In Huawei oceanstorV3, which of the following statements about clones are correct? (Multiple Choice)

The asynchronous remote replication of Huawei OceanStor storage system adopts multi-time slice caching technology, which can make the RPO index of LUN asynchronous remote replication reach the second level.

The InfoEqualizer feature of Huawei OceanStor 9000 is mainly used to manage client connections to Huawei OceanStor 9000, and supports load balancing and failover functions. Special attention should be paid when planning the network. The InfoEqualizer DNS IP address needs to communicate with the Huawei OceanStor 9000 front-end network and customer application network.

An enterprise plans to build three centers in two places on the cloud on HUAWEI CLOUD. The customer requires cross-regional disaster recovery to avoid business interruption. Due to the particularity of the business, the customer requires disaster recovery RPO=0. The technicians provided the customer with SDRS (Storage Disaster Recovery Service) + CBR (Cloud Backup and Recovery) solution of three centers on the cloud, two locations and three centers.
The production center X and disaster recovery center Y were built in Availability Zones 1 and 2 of region A, and the construction of region B. The remote disaster recovery center Z, X, and Z data centers can meet the customer's RPO=O disaster recovery requirements. 1. When all BBUs of the storage controller are damaged, the controller will automatically set the I/O write policy to write-through and lock to ensure data reliability. It cannot be forced to write-back before the fault is recovered.

A company backs up database system data and uses the advanced backup function of Huawei's data protection all-in-one machine. The company's production volume capacity is 4TB, incremental backups are performed every day, and the data change amount is 10GB per day. What is the capacity of volumes need to mount at least?

A company purchased a set of Huawei hybrid flash storage. The current business information is as follows:
(1) Online transaction business: random write IO accounts for 80%;
(2) Online query business: sequential read IO ratio is 90%;
(3) Storage configuration SSD, SAS and NL-SAS three kinds of hard disks.
When storage engineers plan storage services, which of the following are reasonable? (Multiple Choice)

正解：A,B,D 解答を投票する
( ) deduplication means that data is divided into blocks of variable size according to its own content for deduplication, which is mainly used in the field of backup.

M Enterprise uses Huawei data protection all-in-one machine and Huawei backup disaster recovery solution to protect the data of the enterprise business system, including the production system of the enterprise. File servers, database servers, mail servers, and virtual machines. The enterprise creates snapshot copies of data on an hourly level; backup data is replicated off-site, with a multi-copy retention policy; in addition, it also uses the solution of backing up data to the cloud. When the production system of the enterprise fails, the data can be quickly restored by backing up the data. Which of the following options is correct? (Multiple Choice)
