afaik, cxfs is just a rebrand of quantum snfs.

Nope! Cxfs is based on eXtended File System (XFS), a brand new 64 bits journaled file system developped by Silicon Graphics back in the 90's to help provide a secure (journaled) fast and reliable FS for it's Unix based OS - IRIX - running on their Workstations and later on the biggest CC-NUMA servers (up to 4096 CPU with a a single shared addressing space).

With CXFS, the FS structure itself remains quite the same but the metadata operations are centralized on a server (Metadata Server - MDS) to make sure there's no data coruption.

CXFS has become heterogenous over time, with support for IRIX, SOLARIS, AIX, Windows, MAC OS, LInux 32/64, several platforms that have different Endianess and different POSIX compatibility levels.

Quantum Stornext, also knew as ADIC SNFS is different by nature, although some of the mechanisms are similar. There's an old myth that one come from the other, due to the fact that the 2 initial founder of SNFS worked in the XFS team, but at the end of the day, there's has never been any proof of patent infrigment or any sort nor any case between them and SGI... — Preceding unsigned comment added by Eeppe (talk • contribs) 18:44, 10 October 2012 (UTC)[reply]
