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 Storage
fl
ex 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.
