Clustering is
the process of joining multiple servers together to achieve
greater fault tolerance and performance. Just as RAID can
improve the reliability and speed of a single server by adding
hard drive redundancy and flexibility, server clustering can
improve a network's reliability, availability, scalability and
performance. Clustering uses multiple servers to share the tasks
that might otherwise be handled by a single server.
Our Mid-Range
Cluster is the simplest type of clustering. It pairs servers
together so one server acts as a mirror of the other. The
primary server performs the network functions, while the mirror
server duplicates the primary server's activity. The mirror
server can take over for the primary server instantly should the
primary server fail or need to be taken offline for maintenance
or upgrades.
Our High-End
Cluster uses sophisticated clustering schemes to group two or
more servers to provide redundancy, enhance scalability and
improve performance. Additional servers can be brought online as
network needs grow without interrupting existing services.
Server deployments of this type also provide redundancy and
on-the-fly scalability.
