Vital-IT, a Swiss life science initiative that provides computational resources to the Swiss Institute of Bioinformatics and other research institutions, recently acquired an integrated compute and storage cluster that includes a 64-node HP Cluster Platform 3000BL system based on HP BladeSystem c-Class servers and a 13-terabyte HP SFS storage system.
While these storage architectures have served the enterprise computing market well over the years, cluster computing represents a new class of storage system interaction--one requiring high concurrency (thousands of compute nodes) and high aggregate I/O.
Linux clusters are attractive for their price and performance, but more importantly, Linux and open source tools enable our community to work together to tackle large-scale systems software challenges.
