How flat backup can simplify your data storage environment

Flat backup, an alternative to traditional data backup, works with snapshots and replication for near-continuous data protection.

1- #Storage #clusters
provide a consistent file system image across servers in a cluster, allowing the servers to simultaneously read and write to a single shared file system. A storage cluster simplifies storage administration by limiting the installation and patching of applications to one file system. Also, with a cluster-wide file system, a storage cluster eliminates the need for redundant copies of application data and simplifies backup and disaster recovery.
#Red #Hat #Cluster Suite provides storage clustering through Red Hat #GFS

2- #High-availability #clusters
provide continuous availability of services by eliminating single points of failure and by failing over services from one cluster node to another in case a node becomes inoperative. Typically, services in a high-availability cluster read and write data (via read-write mounted file systems). Therefore, a high-availability cluster must maintain data integrity as one cluster node takes over control of a service from another cluster node. Node failures in a high-availability cluster are not visible from clients outside the cluster. (High-availability clusters are sometimes referred to as failover clusters.)
Red Hat Cluster #Suite provides high-availability clustering through its High-availability Service Management component.

3- #Load-#balancing #clusters
dispatch network service requests to multiple cluster nodes to balance the request load among the cluster nodes. Load balancing provides cost-effective scalability because you can match the number of nodes according to load requirements. If a node in a load-balancing cluster becomes inoperative, the load-balancing software detects the failure and redirects requests to other cluster nodes. Node failures in a load-balancing cluster are not visible from clients outside the cluster.
Red Hat Cluster Suite provides load-balancing through #LVS (Linux Virtual Server).

4-#High-#performance #clusters
use cluster nodes to perform concurrent calculations. A high-performance cluster allows applications to work in parallel, therefore enhancing the performance of the applications. (High performance clusters are also referred to as computational clusters or grid computing.)
