Data sharing is a must in today's modern computing world. When the data requirements include allowing a cluster of servers to access a common storage pool, Red Hat GFS is the answer for simplifying your data infrastructure, minimizing storage costs, adding storage on the fly, and achieving maximum uptime. A cluster file system like Red Hat GFS can be used with an IP network block-sharing protocol like iSCSI to provide scalable file serving at low cost. Network File System (NFS) is a common shared storage solution utilized by many infrastructures. However, in some instances, this solution does not scale. How do GFS and NFS compare?
