ensure that each of these private networks uses a unique subnet. This is necessary even if you give each network adapter a unique IP address. For example, if you have two cluster nodes in a central office that
becomes unavailable, and the secondary site, with a minority of nodes, need to be brought into service. Similarly, the ability to force quorum makes it possible to start a cluster that uses the Node and File Share Majority quorum option when none of the available cluster nodes contains a cur...
The number of available nodes depends on the product type you choose. A storage-compute coupled data warehouse (standalone) has only one node. For other types of clusters, the number of nodes can be greater than or equal to 3.Creating a Cluster Go to the page for creating a GaussDB(DWS...

For dedicated clusters, the savedown storage becomes unavailable when you delete a cluster node. For clusters running on a scaling group, the savedown storage location will use a shared volume. This volume exists even after you delete the cluster and can be used by other clusters. You can ...

the world. These ARP packets contain the new MAC address (of the new physical adapter to which the node failed over) and the old IP address. When another machine on the network receives one of these packets, it flushes the old MAC-IP mapping from its ARP cache and uses the new one. ...
Cluster nodes communicate and collaborate through a series of network protocols and services. You should prepare a different number of server nodes according to the concurrency level. Note: Only one node of the cluster can be deployed on a server, and it is not supported to deploy multiple ...
