An enterprise's business data is stored in two data centers, and storage devices from different vendors are deployed.
The SmartVirtualization feature can be used to host and create original LUNs on heterogeneous storage systems in each data center
eDevLUN, and then create an asynchronous remote replication between the eDevLUN and the local LUN on the Huawei storage system at another site to achieve
Data disaster recovery between sites.
Regarding the multi-NameNode concurrency characteristics of Huawei's distributed storage products, which of the following statements are correct ()
The block service provides a linked clone mechanism and supports the creation of multiple snapshots based on a cloned volume. Each snapshot volume has just been created
The data content at the time of arrival is consistent with the data content in the clone volume, and subsequent modifications to the clone volume will not affect the original snapshot and other clones
roll.
In the Oceanstor 9000 storage system, if you want to perform a complete network tuning, you need to
Inspections and adjustments.
In the Huawei dual-active disaster recovery solution, the peak write bandwidth of an application needs to be 10MB/s for single selection, and the average write bandwidth needs to be 200KB/s, and the average write bandwidth is 200KB/s.
The I/O volume is 4KB. The bandwidth utilization rate is 70%. How much bandwidth does the application need to deploy synchronous remote replication?
