Global File System

Red Hat GFS is...

• The only native 64-bit cluster file system on Linux for enterprise workloads - support for x86, AMD64/EM64T, and Itanium
• The most scalable enterprise cluster file system on Linux - supported up to 256 nodes
• Tightly integrated with Red Hat Enterprise Linux (no patching needed)
• The only open source (GPL) cluster file system for enterprise workloads
• POSIX-compliant, meaning applications don't have to be rewritten to use GFS

GFS在群集NAS系统中非常普遍，因为群集中的节点都能同时分享同一存储池，节点可以独立工作也可以相互协作。GFS通常是集成到NAS设备的操作系统中，但是某些情况下，GFS也作为软件层使用，添加到NAS架构的最顶层。
