EtherDrive Storage Provides High Scalability and Low Cost for Hungarian Research Sector [image: Print] <http://www.wwpi.com/index2.php?option=com_content&task=view&id=505&Itemid=0&pop=1&page=0#>
The National Information Infrastructure Development Program<http://www.niif.hu/>is the driving force behind the operation and development of Hungary's research network. The program covers the entire Hungarian science, education and public collection community by providing a networked computer infrastructure and a wide range of communication information, co-op services, and networking applications. The means by which the NIIF Program delivers its grid services is through The Hungarian ClusterGrid Infrastructure Project. The ClusterGrid Project integrates Intel processor PC's into a single, large, countrywide interconnected set of clusters. The PCs are provided by participating Hungarian institutes, such as high schools, universities, or public libraries. Implementing and Coordinating this central infrastructure is the responsibility of the NIIF/HUNGARNET. Members use their PC's for their own purposes during official work hours and offers the infrastructure for high-throughput computing when PC's are not in normal use. The combination of "day-shift" (individual mode) and "night-shift" (grid mode) allows grid administrators to utilize CPU cycles that provide high computational infrastructure to the national research community. NIIF uses EtherDrive Storage Blades for highly scalable storage support in the ClusterGrid project. EtherDrive storage easily accommodates storage needs of the mostly Linux operating system. PC's use Debian GNU 3.1 systems and grid backbone machines use RedHat 7.3 distributions. Servers with dual 2.0 GHz Xeon processors provide the central entry point. The grid uses Condor as the local scheduler where labs are treated as individual pools that are interconnected by Condor's native flocking mechanism. Coraid's EtherDrive Storage Blades provide a low cost networked storage solution using Ethernet connections between the server and a shared storage array (pool). Multiple servers can access a common disk storage system eliminating wasted captive storage. With EtherDrive Storage Blades, the storage pool can be expanded easily with simple Ethernet connections. Storage array performance is limited only by the number of disks configured for RAID striping and the speed of the Ethernet connection at the server. EtherDrive Storage Blades are Direct Network Attached (DNA) block storage. DNA provides an Ethernet interface for hard disk drives. Coraid offers an optional EtherDrive RAIDBlade/20 Controller for users that don't want to use Linux software RAID. coraid.com <http://www.coraid.com/> Close Window <javascript:window.close();> [Non-text portions of this message have been removed] Yahoo!
