Microsoft co-founder Bill Gates stated that Windows Server was Microsoft's "most rigorously tested software to date. Microsoft used Windows Server 's kernel in the development of Windows Vista.
Windows Server comes in a number of editions, each targeted towards a particular size and type of business. NET technology.

Windows Server is available for IA, Itanium, and x64 processors. It supports a maximum of 32 physical processors on IA platform or 64 physical processors on x64 and IA hardware. The Datacenter edition, like the Enterprise edition, supports 8-node clustering. Clustering increases availability and fault tolerance of server installations by distributing and replicating the service among many servers.
This edition supports clustering with each cluster having its own dedicated storage, or with all cluster nodes connected to a common SAN. Windows Compute Cluster Server CCS , released in June , is designed for high-end applications that require high performance computing clusters. 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.

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.
