In this video from LUG 2015 in Denver, James Simmons from ORNL presents: Lustre + Linux – Putting the House in Order. “In the last year great strides have been made to sync up the lustre Intel branch to what is upstream. We present what that current state is as well as what is left for the intel branch to bring this to completion.”
“Monitoring a large Lustre site, running multiple generations of Lustre filesystems can be a challenge. Some equipment offer vendor specific monitoring interfaces while others, built on open source Lustre, have minimal monitoring capabilities. This talk will report on our operational experience using a homegrown python module to collect data from each filesystem. We will discuss in detail how the data is visualized centrally in Splunk and cross-referenced with users workload to analyze and troubleshoot our environment.”
“Intel supports users, system integrators, and OEMs using ZFS with Intel Lustre. In this presentation, we summarize the results of proof-of-concept (PoC) on a variety of the ZFS configurations. We cover sequential and metadata performance, data Integrity, manageability, availability and reliability. The work identifies the areas where development should be focused in order to fill gap in performance or functionality and encourage system administrator to integrate this technology with the existing high availability framework like Pacemaker/Corosync. We also cover the most important tunables for ZFS in combination with Lustre and the most notable metrics for Lustre and ZFS.”
“n this session, Seagate covers configuration guidelines and tuning of LNET Routing from InfiniBand to Ethernet using Lustre 2.1 through 2.6 server/clients as well demonstrating performance results by means of a synthetic benchmark called IOR. In addition, this presentation includes the topic of LNET Router failure and recovery during I/O as well as what environments can expect during these failure events.”
Although there are a number of truly huge implementations of Lustre today, the community is still far from reaching the maximum configurations that the Lustre architecture is designed for. Inside the Lustre File System describes the basics of how the Lustre File System operates with descriptions of the newest features.
In this podcast, Rich Brueckner reports back from the LUG 2015 Lustre User Group Meeting. With something like 188 attendees this year, LUG reflects a user community that has come together to foster the world’s fastest parallel file system.
“Andreas Dilger from Intel presents an overview on the features currently under development for the upcoming Lustre 2.8 and 2.9 releases. This includes Layout Enhancement, Progressive File Layouts, Data-on-MDT, and improved single-client metadata and IO performance. In addition, several Lustre-specific ZFS improvements are also under development that will be available in this timeframe.”
“With the current Lustre Performance Monitoring Tool (LMT) no longer in active development, and the current version incompatible with DNE based Lustre 2.5 deployments, there is a critical need for a new set of tools delivering the same basic Lustre performance metrics with the added ability to work compatibly with contemporary releases of Lustre.”
“The Cray-Seagate partnership is helping expand the boundaries of what’s possible in large-scale, data-intensive computing, far beyond what we could have imagined just 10 years ago. This continued innovation using the Lustre open file system is helping assist data-intense applications critical to advancements in important industries around the world.”
