5 .TH Lustre 7 "2006 Jun 15" Lustre "A high-performance cluster file system"
9 A high-performance file system designed for clusters.
12 is a high-performance, massively-scalable, POSIX-compliant network file system
13 designed for the world's largest high-performance compute clusters. Lustre
14 is under active development from Sun Microsystems (http://www.lustre.org).
16 Lustre filesystems are made up of multiple services typically distributed
17 across multiple nodes. Lustre clients can contact these server nodes over
18 multiple high-speed network fabrics via LNET, the Lustre NETworking
19 system. Clients then present the filesystem at a mount point to userspace.
21 A filesystem is comprised of a
23 , MetaData Target, which stores directory and file meta-information such as
24 file ownership, timestamps, access permissions, etc, and a
27 , Object Storage Targets, which hold the file data in one or more objects.
28 There is typically not a 1:1 mapping of OST objects and what is presented
29 as a file on a Lustre client.
31 Lustre and LNET are implemented as a series of kernel modules, for both
32 servers and clients. LNET networks are defined in the modprobe.conf file on
33 all nodes. Lustre is started on the clients and servers using the
