Enterprise Class Reliability, Availability and Scalability for Subversion
With Subversion Clustering, a central Subversion server is no longer a performance bottleneck. Subversion Clustering has no single point of failure whatsoever. Subversion Clustering’s approach is truly shared-nothing. There is no sharing of disk, CPU, or memory between Subversion servers in a cluster. Subversion Clustering supports dynamic or static load balancing, and failover and recovery are automatic and transparent.
Features:
Dynamically balances workload across multiple Subversion servers at a single location. Each server in the cluster is fully readable and writeable and kept in sync with the others by WANdisco’s unique active-active replication technology.
Has no single point of failure. Subversion Clustering’s approach is truly shared nothing. There is no sharing of disk, CPU, or memory between Subversion servers in a cluster.
Requires no retraining. Developers and administrators use Subversion clients and tools they’re familiar with.
Delivers continuous hot backup, automated disaster recovery and failover capabilities that insure business continuity. Third party disk mirroring solutions aren’t required.
Hot-deploy capabilities allow new servers to be added to the cluster, or existing servers to be taken offline without any interruption in user access.
