Terrascale's TerraGrid is at the heart of the ITI cluster. TerraGrid galvanizes the individual components by providing universal access to all storage systems in the network at unprecedented I/O speeds.

Initial benchmark tests demonstrated the linear scalability of the system. Equipped with inexpensive 32 MB/second IDE disks, each computing node may leverage total I/O performance of seven I/O servers at a bandwidth speed of 200 MB/second to access a single file system.

"The integration of Terrascale's TerraGrid software greatly enhances the overall performance of our computer cluster", stated Dr. Peter Sobe, Parallel Storage Researcher for Medical Applications, ITI, University of Luebeck. "This system is working perfectly. TerraGrid supports applications seamlessly and transparently. Installation is simple and operation is user-friendly. TerraGrid provides access to distributed I/O capacities optimizing network performance. Furthermore, TerraGrid facilitates the deployment and use of clusters by clarifying and simplifying operation", Dr. Sobe added.

"In the coming weeks, we will perform extensive performance and scaling tests with I/O intensive MPI applications to examine the scaling potential of TerraGrid on our eight-node system", stated Prof. Dr.-Ing. Erik Maehle, ITI Director. "Subsequently, we will also test TerraGrid with much larger systems. This work is important for us because we are convinced that I/O problems in cluster computing still require considerable research. The stability of this system is not a concern. Terrascale delivered a very reliable system for our SuSe-based Linux cluster, which we are launching to commemorate the twelfth anniversary of Informatics at the University of Luebeck", Prof. Maehle added.

"TerraGrid dramatically enhances the performance of I/O-intensive parallel applications running on Linux-based cluster or blade servers", stated Gautham Sastri, President and CEO, Terrascale Technologies. "TerraGrid provides parallel access and linear scaling of I/O bandwidth with the addition of resources on networks including GigE, 10GigE, Infiniband, Myrinet and Quadrics. With TerraGrid, the only limitations on system performance are the availability of storage and network bandwidth", Mr. Sastri added.
