Abstract

The goal of this document is to explain the two types of quorums available in Windows Server 2003 clusters – standard and majority node set (MNS) clusters. Currently, the standard quorum that is used by the Microsoft Cluster Service (MSCS) in Microsoft® Windows NT® Server 4.0 and Windows® 2000 Server family of products is sufficient for the majority of situations users will encounter. With the introduction of Windows Server 2003, Microsoft has introduced the MNS quorum, which is primarily for advanced users and other software vendors to create more sophisticated end-to-end solutions.
