Linux NTFS provides Linux kernel drivers, a multiplatform NTFS library, and tools to create, resize, clone, rescue, query, label and fix NTFS volumes, and to undelete, resize, list, and query files for the filesystem used by Windows XP, 2003, 2000, NT4, and Vista. It also provides support for the Logical Disk Manager (LDM) that controls Windows' Dynamic Disks and is used to create software mirrors, stripes, and RAID.
Partition Image is a Linux/UNIX utility similar to Symantec's Ghost. This uility 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 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.
The Parallel Virtual File System is a user-space parallel file system for use on clusters of PCs (and Beowulfs in particular). It provides transparent file striping across multiple machines and includes a loadable kernel module for use with existing binaries. TCP/IP is used for data transmission, and file data is stored on existing file systems on each machine.
Rio (RAM I/O) for FreeBSD is an implementation of the Rio file cache project at Michigan. The basic idea of Rio is to make memory as safe as disk from operating system crashes. Such "reliable main memory" is useful in a variety of contexts, e.g. file systems, transaction systems, or checkpointing.
Samba TNG is a tiny SMB/CIFS suite (server, client, and utilities) for Unix-like operating systems. This software is concentrating on MSRPC interoperability with Windows NT, 2000, XP, Vista, 2003, and 2008. Windows 7 support is in progress. It provides PDC support and tools to remotely administer NT servers and workstations.
