HDFS - Hadoop Distributed File System

HDFS - Apache Hadoop - The Apache Software Foundation! "HDFS is the primary distributed storage used by Hadoop applications. A HDFS cluster primarily consists of a NameNode that manages the file system metadata and DataNodes that store the actual data." - hadoop.apache.org HDFS Users Guide HDFS Architecture Guide See also: HADOOP

Lustre file system

Lustre is a parallel distributed file system, generally used for large scale cluster computing. The name Lustre is a portmanteau word derived from Linux and cluster. For the world's largest and most complex computing environments, the Lustre file system redefines high performance, scaling to tens of thousands of nodes and petabytes of storage with groundbreaking I/O and metadata throughput - lustre.org Lustre (file system) - Wikipedia Whamcloud » New to Lustre?

Solaris File Systems

(Solaris) ZFS has been based in part of NetApp's write Anywhere File Layout (WAFL) system. It evolved pretty far from WAFL and now has many differences. Unfortunately, the related term “SAM” is often confusingly referred to as SAMFS. SAM really refers to storage, archive, and migration, and is a hierarchical storage facility. SAM is actually built into the same executables as QFS and SAMFS, and is separately licensed.

When receivng a UMNT request from an NFS client, rpc.mountd simply removes the matching entry from /var/lib/nfs/rmtab, as long as the access control list for that export allows that sender to access the export. Clients can discover the list of file systems an NFS server is currently exporting, or the list of other clients that have mounted its exports, by using the show- mount(8) command. showmount(8) uses other procedures in the NFS MOUNT protocol to report information about the server’s exported file systems. Note, however, that there is little to guarantee that the contents of /var/lib/nfs/rmtab are accurate. A client may continue accessing an export even after invoking UMNT. If the client reboots without sending a UMNT request, stale entries remain for that client in /var/lib/nfs/rmtab.
