Reparse Point Support in Windows 2000-Based Clusters (262797)

MORE INFORMATION

• Directory Junctions is a technology for a folder to be grafted into another folder on the same local computer. Directory Junctions work when they are mounted on the same volume. If a Directory Junction is mounted such that the target folder and host folder are on different Physical Disk resources, the resources must be in the same cluster group. The Physical Disk resource that contains the host folder should be dependent on the Physical Disk resource that contains the target folder. If the drive that contains the target folder does not come online, the drive that contains the host folder does not start.
• Volume Mount Points (mounted drive) is a feature of Windows 2000 that allows for drives to be grafted into folders on a different drive. Volume Mount Points does not work on a shared disk and is not supported with the existing Windows 2000-based product.
• Remote Storage Service (RSS) allows for infrequently used files to be offloaded to a tape device (hierarchal storage). RSS is not cluster-aware and is not supported to manage a shared disk.
• Remote Installation Services (RIS) uses reparse points for Single Instance Store (SIS) to reduce the size of the install images. RIS is not cluster-aware and is not supported as a Cluster service.
