Fairly convincing arguments. One disk per node. Little mention of a file system though. Email from student Udo Boehm:``We use in the version of Triton/1 with 256 PE's 72 Disks at the moment (the filesystem is scalable up to 256 Disks). These Disks are divided into 8 Groups with 9 Disks. In each group exists one parity disk. Our implementation of the filesystem is an parallel version of RAID Level 3 with some extensions. We use so called vector files for diskaccess. A file is always distributed over all disks of the diskarray. A vectorfile is divided in logical blocks. A logical block exist of 72 physical blocks, each block is on one of the 72 disks and all these 72 physical blocks have the same blocknumber on each disk. A logical block has 18432 Bytes, where 16384 Bytes are for Data. The filesystem uses these logical blocks to save data. We do not use special PE's for the I/O. All PE's can be (are) used to do I/O ! There exists no central which coordinates the PE's.''} }
