HTFS
High Throughput File System (HTFS) is a journaling file system that was used by SCO OpenServer Xinuos OpenServer, previously SCO UNIX and SCO Open Desktop (SCO ODT), is a closed source computer operating system developed by Santa Cruz Operation (SCO), later acquired by SCO Group, and now owned by Xinuos. Early versions of OpenServer were .... The filesystem format is like that of an older SCO filesystem, the Extended Acer Filesystem (EAFS), but designed to be somewhat more future-proof.

Journaling File System
A journaling file system is a file system that keeps track of changes not yet committed to the file system's main part by recording the goal of such changes in a data structure known as a " journal", which is usually a circular log. In the event of a system crash or power failure, such file systems can be brought back online more quickly with a lower likelihood of becoming corrupted. Depending on the actual implementation, a journaling file system may only keep track of stored metadata, resulting in improved performance at the expense of increased possibility for data corruption. Alternatively, a journaling file system may track both stored data and related metadata, while some implementations allow selectable behavior in this regard. History In 1990 IBM introduced JFS in AIX 3.1 as one of the first UNIX commercial filesystems that implemented journaling. The next year the idea was popularized in a widely cited paper on log-structured file systems. This was subsequentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCO OpenServer
Xinuos OpenServer, previously SCO UNIX and SCO Open Desktop (SCO ODT), is a closed source computer operating system developed by Santa Cruz Operation (SCO), later acquired by SCO Group, and now owned by Xinuos. Early versions of OpenServer were based on UNIX System V, while the later OpenServer 10 is based on FreeBSD 10. However, OpenServer 10 has not received any updates since 2018 and is no longer marketed on Xinuos's website, while OpenServer 5 Definitive and 6 Definitive are still supported. History SCO UNIX/SCO Open Desktop In 1987 AT&T Corporation, Microsoft, and Sun Microsystems agreed to combine their versions of the Unix operating system. Santa Cruz Operation (SCO) sublicensed Microsoft's Xenix and wanted to retain the Xenix name, but AT&T said "If they want to call it Unix, they've got to use it the way it is. We don't want another set of variants". SCO UNIX was the successor to Xenix, derived from UNIX System V, UNIX System V Release 3.2 with an infusion of Xenix dev ...
