Bcfg2 helps system administrators produce a consistent, reproducible, and verifiable description of their environment, and offers visualization and reporting tools to aid in day-to-day administrative tasks.

The Enterprise Volume Management System (EVMS) Project has the goal of providing unparalleled flexibility and extensibility in managing storage. It represents a new approach to logical volume management, as the architecture introduces a plug-in model that allows for easy expansion or customization of various levels of volume management.

Partition Image is a Linux/UNIX utility similar to Symantec's Ghost. This utility saves partitions in the EXT2, Reiserfs, NTFS, HPFS, FAT16, and FAT32 file system formats to an image file. The image file can be compressed with gzip or bzip2 in order ... [More] to save disk space, and it can be split in order to fit onto a series of floppy disks. This program can be useful for backup purposes. A boot/root disk is also provided, allowing you to run Partition Image without Linux installed on the hard disk. [Less]

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and grids. It is based on a hierarchical design targeted at federations of clusters.
