“HPC systems have kept growing in the last decades, producing vast amounts of data. Over time, we noticed how increasingly difficult it is to manage these data. Lustre as parallel filesystem is widely used in the HPC domain. It answers most of the requirements of the new generations of the HPC systems. Before Lustre 2.4, the metadata operation was managed by single metadata server and target. Such single operation became a kind of bottleneck. As a first step to help solving this problem Lustre multiple metadata server and targets (DNE) came out with Lustre 2.4. This talk will cover the first experience with Lustre DNE, showing some results and discussing the next step.”
In this video from the 2014 HPC Advisory Council Spain Conference, James Coomer from DDN presents: Adventures in Parallel Filesystems. “IT is currently in the middle of a rapid evolution in both hardware (flash-technolo- gies) and software (object-storage approaches). With respect to parallel filesystems these advances can potentially both speed up IO and better cope with the volume of data – all at lower cost. We report the results of a number of technology evaluations around parallel filesystems and provide some insights into how flash and object-stores will impact HPC in the coming years.”
The Lustre file system is a open source, parallel file system that supports the requirements of leadership class HPC and Enterprise environments worldwide. Lustre provides a POSIX compliant interface and scales to thousands of clients, petabytes of storage, and has demonstrated over a terabyte per second of sustained I/O bandwidth. Many of the largest and most powerful supercomputers on Earth today are powered by the Lustre file system, including over 60% of the TOP100 sites.
The recent release of a commercial version of the Lustre* parallel file system was big news for business data centers facing ever expanding data analysis and storage demands. Now, Lustre, the predominant high-performing file system installed in most of the supercomputer installations around the world, could be deployed to business customers in a hardened, tested, easy to manage and fully supported distribution.
“Sharing a common code base with other Open ZFS platforms has given ZFS on Linux the opportunity to rapidly implement features available on other Open ZFS platforms. At present, Illumos is the reference platform in the Open ZFS community and despite its ZFS driver having hundreds of features, ZoL is only behind on about 18 of them.”
