In this video from the Lustre User Group 2013, Giuseppe Bruno from the Bank of Italy presents: Performance & Functionality Testbed for Clustered Filesystems.
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.
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.”
In this video from the Lustre User Group 2013, Hugo Falter from ParTec presents: LUG2013 EOFS Update. As Director of the EOFS Administrative Council, Falter provides an excellent overview on what’s going on with European supercomputing initiatives.
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.
