Video: EIOW Exascale I/O Working Group

By Rich | Published May 18, 2013

In this video from the Lustre User Group 2013, Meghan McClelland from Xyratex presents: EIOW – Exascale I/O Working Group.

There is a fierce competition on the storage market to offer the best performing devices, with great management at a low price. The EIOW group, from the outset, decided that it would not attempt to offer an end-to-end solution, which would necessarily involve competing instead of working with storage providers. The focus of EIOW is on middleware to provide, for example, schemas describing data structure and layout, novel access methods to data for applications, a uniform data management infrastructure and a framework for the implementation of layered I/O software, similar in spirit to HDF5 as a specialized use of a parallel file system. We decided EIOW should be open, and have interfaces to layer on lower level storage infrastructure such as object stores, databases and file systems as provided by storage providers, to allow their expertise and leadership in this area to continue to benefit the HPC community.

Slidecast: ClusterStor 1500 Departmental Scale-Out Storage for HPC

By Rich | Published May 14, 2013

In this slidecast, Ken Claffey from Xyratex describes the company’s new ClusterStor 1500 storage system. Designed for scale-out HPC storage solutions, the ClusterStor 1500 delivers HPC performance and efficiency with help from the Lustre file system.

Departments within larger organizations or medium-sized enterprises today, especially in the commercial, academic and government sectors, represent an underserved market. They need high-performance and scalable storage solutions that are cost-efficient, easy to deploy and manage and reliable even under heavy workloads,” said Ken Claffey, senior vice president of the ClusterStor business at Xyratex. “Growth in this market segment is being driven by the increasing adoption of simulation applications in a wide range of industries from car and aircraft design to chemical interactions and financial modeling. Traditional enterprise storage systems are simply not designed to meet the performance needs of these applications, so we engineered and built the affordable and modular ClusterStor 1500 to bring the performance power of Lustre to this underserved and growing market in the way that only ClusterStor can.”

With the ability to scale performance from 1.25GB/s to 110GB/s and raw capacity from 42TB to 7.3PB, ClusterStor 1500 is purpose-built to satisfy data intensive department level compute cluster needs, ClusterStor 1500 is designed to provide best in class scale-out storage for middle tier high performance computing environments. The ClusterStor 1500 solution features scale-out storage building blocks, the Lustre parallel filesystem and a comprehensive management platform that eliminates the guesswork usually associated with building and optimizing your own HPC storage solution.

Video: Aeon Computing Showcases Intelligent Disk Arrays with Lustre and ZFS

By Rich | Published May 11, 2013

In this video from the Lustre User Group 2013, Doug Johnson from Aeon Computing describes the company’s Hydra storage arrays that marry the speed of Lustre with the HA capabilities of ZFS.

The Hydra60 is a combination Lustre OSS (object storage server) and OST (object storage target) with two active/active failover nodes and shared storage in a single system chassis with an ultra dense 60 drive 6Gb SAS storage infrastructure. With a unified and zonable 6Gb SAS dual-ported backplane and drives the Hydra60 can sustain a remarkable performance while providing high-availability to volumes or object storage. With external interface options including FDR Infiniband, 40/10GbE 1Gb Ethernet and supporting Linux and Lustre releases 2.x the Hydra60 makes an excellent storage platform for Lustre performance with HA operation. The design of Hydra60 provides an affordable, redundant and resilient storage platform by leveraging RAIDZ thereby eliminating the cost of hardware RAID controller technology.”

Jeff Layton on Tools for Data Migration

By Rich | Published May 10, 2013

Over at HPC Admin, Dell’s Jeff Layton writes that with today’s explosive data growth, at some point you will have to migrate data from one set of storage devices to another. To help move things along, he provides an overview of data migration tools.

At some point during this growth spurt, you will have to think about migrating your data from an old storage solution to a new one, but copying the data over isn’t as easy as it sounds. You would like to preserve the attributes of the data during the migration, including xattrs (extended attributes), and losing information such as file ownership or timestamps can cause havoc with projects. Plus, you have to pay attention to the same things for directories; they are just as important as the file themselves (remember that everything is a file in Linux). In this article, I wanted to present some possible tools for helping with data migration, and I covered just a few of them. However, I also wanted to take a few paragraphs to emphasize that you need to plan your data migration if you want to succeed.

As referred to in Layton’s article, this video from the Lustre User Group 2013 features Marc Stearman from LLNL presenting: Sequoia Data Migration Experiences. Download the slides (PDF).

Podcast: Radio Free HPC Looks at Lustre with Brent Gorda

By Rich | Published May 7, 2013


 
In this podcast, the Radio Free HPC team discusses Lustre and LUG 2013 with Brent Gorda. Now part of Intel in their High Performance Data Division, Gorda was CEO of Whamcloud when the company was acquired last summer.

Gorda recently wrote a post about the rapid growth of the Lustre community, so we started our discussion there and learned a good deal more about the popular file system.

Video: DataDirect Networks Update

By Rich | Published May 5, 2013

In this video from the Lustre User Group 2013, Jeff Denworth from DDN presents: DataDirect Networks Update.

DDN has developed a Hadoop solution that is all about time to value: It simplifies rollout so that enterprises can get up and running more quickly, provides typical DDN performance to accelerate data processing, and reduces the amount of time needed to maintain a Hadoop solution.” said Dave Vellante, Chief Research Officer, Wikibon.org. “For enterprises with a deluge of data but a limited IT budget, the DDN hScaler appliance should be on the short list of potential solutions.”

Video: Aeon Computing Big Data Storage with Lustre and ZFS

By Rich | Published May 4, 2013

In this video from LUG 2013, Jeff Johnson from Aeon Computing presents an overview of the company’s innovative Lustre storage solutions.

Our focus is on the design and deployment of highly-integrated HPC, clustered computing, and storage solutions for all areas of computer-aided research and production. With over 55 years of staff experience in high-performance computing, enterprise computing architectures, and data storage, our focus is on architecting a perfectly-suited solution for your needs. We do not adhere to the large manufacturer approach of “one size fits most”. Every application or research methodology is different. We prefer to learn about our customer’s research, their needs and challenges. Our strength comes from being able to draw from many different types of technologies and configuration approaches. Our goal is to design and deploy a cluster or system for our customers that avoids needless bottlenecks, limitations or design and configuration flaws that are commonly found in solutions designed by companies that are more focused on profits or sales incentives from manufacturers.”

Sage Weil Presents: An Intro to Ceph for HPC

By Rich | Published April 25, 2013

In this video from the Lustre User Group 2013 conference, Sage Weil from Inktank presents: An Intro to Ceph for HPC.

Ceph is a free software unified storage platform designed to present object, block, and file storage from a single distributed cluster. Ceph’s main goals are to be completely distributed without a single point of failure, scalable to the exabyte level, and freely-available. The data is seamlessly replicated, making it fault tolerant. Ceph is a software-based solution and runs on commodity hardware. The system is designed to be both self-healing and self-managing and strives to reduce both administrator and budget overhead.
