Active-Active Data Centers Solution

Active-Active data centers Solution mean that both data centers are in operation and can undertake production business at the same time, in order to improve the overall service capability of the data center and the utilization rate of system resources, realize the strict requirements of RPO (Recovery Point Objective)=0 and RTO (Recovery Time Objective)=0, and enhance the continuity of the enterprise business system to a higher level. continuity of enterprise business systems to a higher level.

Symmetrical Dual Active Storage(SDAS) is an upgrade on dual-controller technology, compared with dual-controller technology, to achieve redundancy between two dual-controller storage devices, dual-controller in the event of a double-point failure will lead to business interruption, while symmetric dual activite in a storage device in the event of a double-point failure is still able to be provided by the other storage device to provide storage services, to ensure the continuity of the business.

In response to the need for disaster backup and business continuity, Symmetric Dual Active Storage technology has emerged, characterized by:

• The two LUNs with the double-activation protection feature are located in different cabinets in the same data center or in two data centers that are far away from each other.
• Both LUNs can be made available for server access at the same time.
• Both LUNs have identical data and protect each other.
