Question 176

Which of the following statements about high performance technology in HyperMetro are true? (Multiple Choice)

A.In the preferred array mode, when the host service accesses time, the I/O will only be distributed in load balance on the preferred array path set by the user. Arbiter server mode cannot be configured when this mode is configured.

B.HyperMetro uses the granularity of host I/O to perform concurrent and mutual exclusion on the LBA interval between host I/O accesses and distributed range locks, so as to achieve the purpose of two-way real-time synchronization. This solution can save unnecessary data transmission between arrays. Auxiliary bandwidth, and effectively reduce the number of data transmissions.

C.The streamlined copy quickly identifies the source of the data copy through the hardware chip. Find the zero data. During the copying process, for the special identification of all zero data, only a small special page is transmitted to the opposite end, and the full amount is no longer transmitted.

D.HyperMetro optimizes the data transmission between arrays at the protocol level through the FastWrite function, and applies the First Burst Enabled function of the SCSI protocol, which reduces the link transmission intersection of the write data by half.

Question 177

When doing the main and standby disaster recovery design, which of the following description of the slave side is correct?

A.The capacity of the slave lun is the same as that of the master lun

B.Use the same type of disk as the primary side

C.The RAID setup is the same as the primary side

D.Use the same number of disks as the primary side

Question 178

Which of the following statements about RTO recovery time objectives is correct?

A.Time period from business suspension to data recovery

B.Time period from business recovery to data recovery point

C.Time period from data loss to data recovery point

D.Time period from business cessation to business recovery

Question 179

Volume mirroring function, which of the following statements is correct? (Multiple Choice)

A.The storage data of a lun is 2G, and a volume image is created for the lun, a copy is generated when it is created, and the total amount of incoming items and copies after generation is 4G

B.When configuring volume mirroring, it is required that the volume mirror copies come from different hard disk domains

C.After the volume mirror is created for the volume, the internal information exchange is performed, and the lun ID of the server read I/O should be changed

D.External lun configuration volume mirror, you can also configure the external as a mirror copy

Question 180

The feature of Huawei SmartCache is to form a smart cache pool of SSD disks and divide them into multiple partitions in the smart cache pool. Different services cannot share partitions to ensure the independence of services.

A.FALSE

B.TRUE
