xfsprogs Description

Advertisement xfsprogs is a System Utilities software developed by Silicon Graphics International Corp. After our trial and test, the software is proved to be official, secure and free. Here is the official description for xfsprogs: XFS combines advanced journaling technology with full 64-bit addressing and scalable structures and algorithms. This Combination delivers the most scalable high-performance FileSystem ever conceived. Features The XFS filesystem provides the following major features: Quick Recovery The XFS journaling technology allows it to restart very quickly after an unexpected interruption, regardless of the number of files it is managing. Traditional filesystems must do special filesystem checks after an interruption, which can take many hours to complete. The XFS journaling avoids these lengthy filesystem checks. Fast Transactions The XFS filesystem provides the advantages of journaling while minimizing the performance Impact of journaling on read and write data transactions. Its journaling structures and algorithms are tuned to log the transactions rapidly. XFS uses efficient tree structures for fast searches and rapid space allocation. XFS continues to deliver rapid response times, even for directories with tens of thousands of entries. Efficient Allocations XFS implements extremely sophisticated space management techniques. Efficiency in space management has been achieved through the use of variable sized extents, rather than the simple single-block-at-a-time mechanism of many other filesystems. XFS was the first filesystem to implement delayed space allocation for buffered writes, supports Direct I/O, provides an optional realtime Allocator, and is able to align allocations based on the geometry of the underlying storage device. The XFS allocator performs admirably in the presence of multiple parallel writers, and is renowned for its resistance to space fragmentation under such conditions. Excellent Bandwidth XFS is capable of delivering very close to the raw I/O performance that the underlying hardware can provide. XFS has proven scalability on SGI Altix systems of multiple gigabytes-per-second on multiple terabyte filesystems. - Massive Scalability
