1. High Scalability (Scalability), the enterprise in accordance with the data growth increases node database processing ability;
2. High Availability (High the Availability), when a node failure, other nodes will automatically take over, its capability of providing disaster to a certain extent, realize the system High Availability;
3. The operation is simple, can be established in a mature Cluster File System, such as Veritas, can be directly built on Shared storage array or logical volume manager above the solution;
Using GBASE 8 s SDS the advantages of a high availability architecture is as follows:
* high availability based on Shared storage architecture
* managed by CM and automatic maintenance
* the master node (Primary) and auxiliary nodes (SDS) are read/write
* the master node failure, auxiliary nodes automatically take over service (upgrade master node)
* when there are multiple auxiliary nodes, CM will according to the auxiliary nodes load
* option which node to upgrade the master node
* failover time within 1 minute
* good scalability
* transparent to applications
