CLUSTERS

Compute Clusters

ClusterVision's compute clusters consist of a number of AMD or Intel processor based servers, interconnected by Gigabit Ethernet and an optional high-bandwidth, low-latency network interconnect such as InfiniBand or Myrinet.

The clusters are usually only connected to the outside world through one node called the master node. The master node runs all central services such as the queuing system, the job scheduler and a network file system. Furthermore, it acts as the login and compile node.

The master node is in control of all slave nodes and provides a single point of administration for the whole cluster. Sometimes more than one master node is used to provide redundancy or to balance the load of the central services in case of a large cluster.

Our compute clusters run Bright Cluster Manager™.

Storage Clusters

ClusterVision's storage clusters combine high-end commodity server hardware with high-quality SATA, SAS or FCAL (Fibre Channel) RAID units or NAS servers to build clusters of file servers with virtually unlimited storage capacity.

Storage clusters can be organised as a cluster of Network Attached Storage (NAS) servers, each with a separate large file system accessible from the outside network, or as Storage Area Network (SAN), whereby one or more servers access a number of RAID units through a Fibre Channel network. In both cases, the GPFS or Lustre file systems can be used to provide a high-performance parallel file system.

All our storage clusters run Bright Cluster Manager.
 

Database Clusters

ClusterVision's database clusters provide a fully redundant, turnkey database solution by combining elements from our compute and storage clusters with a parallel database and Bright Cluster Manager.

Available databases include Oracle 11g and MySQL Cluster. ClusterVision is world-wide Oracle partner.
