in many cases, the number of clusters is not known in advance. Various methods can be used to estimate the optimal number of clusters, such as the elbow method, silhouette analysis, or gap statistic. These meth
--remap-column can be employed to handle cases in which primary and unique key values are overlapping between source clusters, and it is necessary that they do not overlap in the target cluster, as well as to preserve other relationships between tables such as foreign keys. --remap-column ...

point as a cluster separately. It then merges the two closest clusters into a single cluster at each iteration until only one cluster contains all of the data points. This procedure results in a dendrogram, which is a tree-like diagram showing the hierarchical connection between the clusters ...
The only exception is that while being migrated to another WSFC cluster, an availability group can temporarily straddle two clusters.Note For information about availability groups on Linux, see Availability groups for SQL Server on Linux.In an HA configuration, a cluster role is ...
For example, the term "database replica" is used in the names of the Always On dynamic management views that return information about availability databases: sys.dm_hadr_database_replica_states and sys.dm_hadr_database_replica_cluster_states. However, in SQL Server...
Windows requires a Windows Server Failover Cluster (WSFC). Each availability replica of a given availability group must reside on a different node of the same WSFC.

VDL deployed two SIOS DataKeeper clusters; one two-node cluster works as a file server and iSCSI server while the other supports a SQL Server (ERP) cluster and Dynamics NAV web services. The implementation took less than one day. During the system failover test, the network services team fa...
