Lustre Monitoring Tool

The Lustre® file system is an open-source, parallel file system that supports many requirements of leadership class HPC simulation environments. Born from from a research project at Carnegie Mellon University, the Lustre file system has grown into a file system supporting some of the Earth’s most powerful supercomputers.

Lustre Basics

The Lustre architecture is a storage architecture for clusters. The central component of the Lustre architecture is the Lustre file system, which is supported on the Linux operating system and provides a POSIX ^*standard-compliant UNIX file system interface. Lustre’s scalable architecture has three main components: The Metadata Server, Object Storage Server, and clients.

• The Metadata Servers (MDS) provide metadata services for a file system and manages a Metadata Target (MDT) that stores the file metadata.
• The Object Storage Servers (OSS) manage the Object Storage Targets (OST) that store the file data objects.

At scale, a Lustre file system cluster can include hundreds of OSSs and thousands of clients. More than one type of network can be used in a Lustre cluster. Shared storage between OSSs enables failover capability.
