After testing, the bandwidth of the two data centers of the customer is 155Mbit/s, the peak write bandwidth of an application is 9.8MB/s, and the average
The write bandwidth is 300KB/s, the average write I/O size is 4KB., and the bandwidth utilization rate is 70%. Colleagues choose active and standby synchronous remote replication for disaster recovery
Scheme, the scheme:
Huawei's end-to-end active-active data center solution is divided into 6 logical levels, namely storage layer, computing layer, application layer, and network layer.
Network layer, transport layer and security layer, the design points of each layer include: (multiple choice)
Single-choice Which one of the following descriptions about the Oceanstor 9000Wushan file system is wrong?
Huawei Oceanstor 9000 alarm notification methods include email notification and SMS notification
A bank’s production center and disaster recovery center both use Huawei’s hyper-converged storage products. The two centers communicate Disaster recovery through asynchronous replication. The copied network type can support GE/10 GE/25 GE
(single choice) Which load balancing method does the Huawei OceanStor 9000 InfoEqualize feature not support?
Synchronous remote replication can be used for disaster recovery in the same city. Single-select FC link is recommended. Asynchronous remote replication can be used for remote disaster recovery.
In order to reduce costs, it is recommended to use an IP link.
A storage cluster has five P36 nodes, using the front and back 10GE networking mode. The front-end service network provides two 10GE interfaces.
When deploying distributed file system services and object storage services in a mixed manner, the number of IP addresses that need to be planned for the front-end business network is: A.11
B.21
C.31
D.41
If the alarm indicator of the storage controller enclosure is yellow, it indicates that the storage system has a critical alarm.
Which of the following ideas and methods to solve the problem of QceanStor9000 DeviceManager. server is correct is:
