In the same city set up two data centers to do synchronous replication, located in another remote data center to do asynchronous remote replication

Set up two data centers in the same city to form a dual disaster recovery network

Set up a data center in the localand remote sites to form a dual-active disaster recovery network

In the same city set up two data centers to do double live in another remote data center to do asynchronous remote replication

Huawei Oceanstor 9000 can configure different data protection levels for different directories / files.

Data written to Huawei OceanStor 9000 system will be divided according to the size of 4G chunk.

Every N chunk, according to Erasure code algorithm to calculate M chunk calibration fast.

The utilization of protected data space is about N / (N + M), the reliability of the data is determined by the value of M, the greater the M is, the higher the reliability.

A client business IO load random read that accounts for more than 60% using SATA, SAS for staging storage, use SSD to do cache, so it will effectively reducecosts and improve random performance indicators

If hot spot data is scattered and changing rapidly, it is recommended to use tiered storage

If there are many SSDs and hotspots, Smart Cache is the best choice

If you have a small amount of SSD data,use a tiered storage disk for more utilization

True

False

The local storage system does not occupy the local storage system when using LUNs in heterogeneous storage systems

For external LUNs, the local storage system can set value-added functions such as remote replication, snapshots, etc.

smartVirtualization uses multipathing software to connect heterogeneous storage in a multipath-redundant manner

smartVirtualization Dictate write data write efficiency is higher than the write-back efficiency

The automatically created Asynchronous Remote Copy snapshot can either be a private quick pick or a public one.

In a DR scenario, it is recommended to create a virtual snapshot of the secondary LUN and map it to the host for access.

In remote replication link networking, parallel networking is better than crossover networking.

The number of LUNs in the consistency group should be as small as possible, and only the LUNs that have write dependencies on the same application are placed in a consistency group.
