It is designed to be deployed on numerous computers to be clustered together to achieve supercomputing speeds. Each Compute Cluster Server network comprises at least one controlling head node and subordinate processing nodes that carry out most of the work. It ties nodes together with a powerful inter-process communication mechanism which can be complex because of communications between hundreds or even thousands of processors working in parallel.
The application programming interface consists of over functions. A job launcher enables users to execute jobs to be executed in the computing cluster. Windows Storage Server , a part of the Windows Server series, is a specialized server operating system for network-attached storage NAS.
Launched in at Storage Decisions in Chicago, it is optimized for use in file and print sharing and also in storage area network SAN scenarios. It is only available through Original equipment manufacturers OEMs. Windows Storage Server NAS equipment can be headless , which means that they are without any monitors, keyboards or mice, and are administered remotely.
Such devices are plugged into any existing IP network and the storage capacity is available to all users. Multiple such NAS servers can be clustered to appear as a single device, which allows responsibility for serving clients to be shared in such a way that if one server fails then other servers can take over often termed a failover which also improves fault-tolerance.
Windows Storage Server can also be used to create a Storage Area Network , in which the data is transferred in terms of chunks rather than files, thus providing more granularity to the data that can be transferred. This provides higher performance to database and transaction processing applications. Single instance storage SIS scans storage volumes for duplicate files, and moves the duplicate files to the common SIS store. The file on the volume is replaced with a link to the file.
