Two Sets of OceanStor Unified Storage with Synchronous Remote Replication

question 373

Multiple Choice

Two sets of OceanStor unified storage with synchronous remote replication are effective in the following ways to improve host write performance on the primary storage: (Multiple choice.)

• A) RPO does not require 0 for the scenario, it is recommended to use asynchronous remote replication.
• B) The main storage using smart cache acceleration, speed up the main storage IO processing speed.
• C) According to the service pressure of the LUNs stored on the primary side, assign the home controllers of each LUN to the A and B controllers.
• D) If you are using an asynchronous remote replication scheme, you need to design a startup synchronization time based on the RPO metrics and consider the setting possible startup synchronization time during the business.
