Intel® Solutions for Lustre*
Data-intensive HPC applications pose strong demands on storage systems to feed large volumes of data into large-scale simulations, multi-dimensional modeling, and computational data analyses. Long-standing file systems used to share data across a network, such as the Network File System (NFS), were not designed with large numbers of clients running I/O-intensive applications in mind. In large HPC environments, NFS servers therefore quickly become a bottleneck that can grind an otherwise optimally functioning cluster to a halt. Distributed file systems such as Lustre, on the other hand, spread the I/O workload over many servers and are therefore perfectly suited for large-scale computational environments.
The Atipa LZ-60v2 and LZE-576v2 High Performance Storage Solutions provide easily usable, scalable Lustre storage solutions for use in academia, government, and industry. Our storage solutions are designed from the ground up to harness the power of the Lustre parallel file system with the data integrity of the Zettabyte File System (ZFS). The Atipa LZ-60v2 is targeted towards users who need a fast affordable storage solution without all the bells and whistles of an enterprise appliance. The Atipa LZE-576v2, on the other hand, is our flagship enterprise appliance equipped with high-availability features and 24/7 support. In addition to our reference architectures, we also offer flexible custom storage solutions designed to fit your needs.
Entry-Level Lustre Solutions
The LZ-60v2 is Atipa’s entry level Lustre appliance for users in need of fast scratch space with small to medium capacity or for users looking for a proof-of-concept that Lustre will accelerate their workload. The solution consists of one combined metadata/management server (MDS/MGS) and three dedicated object storage servers (OSS) with a total storage capacity of up to 60TB* in only 4U of rack space. Storage capacity can be expanded with the LZ60v2-ext expansion module, which increases the available storage up to 140TB* and adds an additional 4U of rack space to the solution. Performance can be increased nearly linearly by adding additional LZ-60v2 modules.

Enterprise-Level Lustre Solutions
The LZE-576v2 is Atipa’s 2nd Generation flagship Lustre appliance for enterprises. The starting configuration consists of one Metadata and Management Module and one Object Storage Module. The Metadata and Management Module contain one metadata server, one management server, one metadata target, and one management target. The Object Storage Module contains two object storage servers and eight object storage targets (four for each object storage server). The entire solution provides 4.4TB of metadata storage and 576TB of usable Lustre storage in 12U of rack space. The modular architecture provides an easy way to scale both capacity and performance by adding additional Metadata and Management Modules and/or Object Storage Modules.
Atipa partners with Intel to offer world class 24/7 Lustre support around the world for enterprise appliances. Atipa engineers are the central point of contact for all support tickets and take the lead in Level 0, Level 1, and Level 2 support issues. This includes, but is not limited to, assisting in collecting diagnostics information, reproducing the problem, eliminating hardware faults. If needed, support tickets are escalated to Intel for Level 3 support (code fixes) with a severity representing the operational impact of the reported issue. Severity 1 (file system is down) issues trigger a broadcast to the entire Intel High Performance Data Division (HPDD) team and have a response time of less than 4 hours.

What Does a Lustre Solution Look Like?
A Lustre file system is typically comprised of multiple components, each of which has a well-defined role in the operation of the file system. The three main components are the Management Server (MGS), the Metadata Servers (MDS), and the Object Storage Servers (OSS). The Management Server and Metadata Servers are the brains of the file system, keeping track of file system configuration and file locations, while the Object Storage Servers are the workhorses moving bulk data between the backend storage and the clients. Intel® Enterprise Edition for Lustre* supplements these components with Intel® Manager for Lustre*, an easy-to-use web-based central access point to manage and monitor the Lustre file system. A detailed overview of Intel® Manager for Lustre* can be found on the Intel® Solutions for Lustre* tab.
The Management Server, Metadata Servers, and Object Storage Servers each have their own backend block storage, called targets, designed to match their specific duties. The Management Target (MGT) stores file system information, the Metadata Targets (MDT) store file attributes, and the Object Storage Targets (OST) store actual file data. When a client needs to access a file, it requests the location of the file on the OSTs from the MDS. Once the file is opened, data is transferred directly between the client and the OSSs. The MDS itself does not participate in any I/O to and from the file.
The components of a Lustre file system are typically connected by two networks: a management network and a high-speed data-transfer network. The management network is used to deploy and monitor the different Lustre servers, while the high-speed data-transfer network is used to move data between the backend storage and the clients. The following image illustrates how the different components of a Lustre system are tied together by the two networks:
The roles of the Lustre file system components are summarized in the following table:
