Clustering is the practice of connecting multiple servers or processors together into a single, unified computing resource. Processors can be of the same architecture (homogenous) or different architecture (heterogenous). Clustering common of the shelve servers is commonly used for many years by Universities and Research Departments to build powerful supercomputers. The concept is simple and proven.
At a time when budgets are receding, mission-critical applications – from databases to messaging systems to web servers to you-name-it – continue to devour storage capacity and hours of very expensive storage management time, at an alarming rate. Many enterprises find themselves purchasing more capacity than necessary due to inefficient use of their storage infrastructure, and overworked administrators are frustrated at their inability to keep up with the nonstop storage provisioning demands caused by the downpour of data. learn more
NAS (NFS) Failover is basing on two nodes of active-passive configuration. It may be one cluster that is distributed between two locations. Once configured, all data written to the primary server are mirrored to a secondary server. In short, it means that in a data loss situation - on primary server (one of two mentioned nodes) - Open-E DSS V6 automatically switches operation to the secondary server. NFS locks are also reassigned to the secondary server after the primary server fails. Complicated? Perhaps. Effective? Certainly!
