Clustering

Clustering is used to increase storage stability and/or increase total available storage size. Clustering requires at least two servers to be present on the network. Three types of clustering are supported in Storageflex software.

•Multihost Failover is used to increase storage stability on the network. The idea is to use computers in cluster as spare ones. When one system fails, the others are continuing to work with very short period of network connection loss (less than a minute).

•Aggregation is used to increase available storage size. When this type of clustering is used, all the servers in cluster will be visible as one virtual storage.

•Mirroring is used to protect data integrity. The idea is to mirror data across the servers in the cluster.
