Intel Lustre Making Parallel File Systems Simple

Intel Lustre is an open-source parallel file system and is used in some of the largest HPC clusters in the world due to its high performance and scalability. Lustre utilizes the following concepts and components to present a unified Lustre file system; Management Server (MGS), Management Target (MGT), Metadata Servers (MDS), Metadata Targets (MDT), Object Storage Servers (OSS), Object Storage Targets (OST), Lustre clients. Take a look at our entire line of Intel servers.

MDS makes metadata available to clients via MDTs. So each MDS manages names and directories in the Lustre file system, and provides network connectivity for one or more MDTs, which are local to the MDS. MDTs store metadata (filenames, directories, permissions), and there is only one MDT per Lustre file system.

OSS provides I/O and network connectivity for one or more local OSTs. The OST stores the actual file data on one or more OSSs. A single Lustre file system can have many OSTs, and you can stripe across many OSTs for performance using a Logical Object Volume (LOV). There is a lot of flexibility regarding where the MDT or OSTs are located, but normally, an OSS has four or more OSTs.

Meta-data is one of the most critical and limiting factors in a Lustre file system. Some configurations place the metadata on flash storage to increase speed and lower latency. Intel Lustre has high availability features, such as active/active OSSs with SAN connectivity to shared disks, and fail-over MDS systems. An interesting reliability feature that Lustre implements is that the Lustre client does not directly write to the file system served by the OST. Instead, the OSS does the file system modifications. This can isolate the file system from incorrectly configured or defective clients, and forms an additional layer of protection against file system corruption.

Intel Manager for Lustre

Intel Manager for Lustre software includes simple, but powerful, management tools that provide a unified, consistent view of Lustre storage systems and simplify the installation, configuration, monitoring, and overall management of Lustre. The manager consolidates all Lustre information in a central, browser-accessible location for ease of use.

Integrated Apache Hadoop Adapter

When organizations operate both Lustre and Apache Hadoop within a shared HPC infrastructure, there is a compelling use case for using Lustre as the file system for Hadoop analytics, as well as HPC storage.

Intel Enterprise Edition for Lustre includes an Intel-developed adapter which allows users to run MapReduce applications directly on Lustre. This optimizes the performance of MapReduce operations while delivering faster, more scalable, and easier to manage storage.

Performance and Affordability

Intel EE for Lustre software has been designed to enable fully parallel I/O throughput across thousands of clients, servers, and storage devices. Metadata and data are stored on separate servers to allow optimization of each system for the different workloads they present. Improved metadata scalability using Distributed Namespace (DNE) feature is now integrated in Intel Manager for Lustre. Intel EE for Lustre can also scale down efficiently to provide fast parallel storage for smaller organizations.

Intel EE for Lustre software is based on the community release of Lustre software, and is hardware, server, and network fabric neutral. Enterprises can scale their storage deployments horizontally, yet continue to have simple-to-manage storage.

How it works: Lustre has five major component Groups



Lustre has five major component Groups Supermicro 1U SuperServer 6018TR-T Supermicro 1U A+ Server 1012G-MTF Supermicro 4U SuperStorage Server 6048R-E1CR24L Supermicro 2U SuperServer 5028R-E1CR12L

Management Server (MGS): Lustre servers (MDS and OSS) provide information to the MGS, while the Lustre clients retrieve information from the MGS. In common setups, the MGS is often a shared server with the MDS for simplicity.
  • Management Target (MGT): Stores information provided by the Lustre servers.

Metadata Server (MDS): A Lustre Server that does the storing of the metadata (the filenames and layout, permissions, and directory location) and provides this information to the clients.
  • Metadata Target (MDT): Stores the metadata and is attached to one or more MDSs. This can be directly attached storage (DAS) but is commonly on shared storage for failover setups. As the MGS needs to provide metadata quickly to the clients, faster storage such as SSDs are commonly used for MDTs. It is also good practice to backup the MDT, or at least have it in a RAID configuration that would provide some protection from lost data.

Object Storage Server (OSS): A Lustre Server that acts as the actual storage server for Lustre. It stores and provides the data to the clients. More OSSs can mean better performance, and OSSs can be added to upgrade the system for performance, and capacity.
  • Object Storage Target (OST): Holds the data for Lustre. With larger OSSs, there is now usually one OSS per OST, but multiple OSTs can be attached to the OSS. OSTs can be added to an OSS later on to provide more storage.

Clients: In HPC, the compute nodes which use the Lustre filesystem to store and retrieve data. To do this, the Management Client (MGC), Metadata Client (MDC), and the Object Storage Clients (OSCs) are all included in the Lustre client software stack.
  • Mounts Lustre

The Lustre Network (LNET) is the networking application program interface (API) which is used to provide all information and data across the network. Most commonly, InfiniBand and/or Ethernet is used, with InfiniBand being a stronger choice due to its low-latency and availability of high bandwidth. Please note that both InfiniBand and Ethernet can be used simultaneously as the LNET so that clients which do not have InfiniBand can still mount the Lustre filesystem through Ethernet.
