I cannot say enough good things about Panasas. I took the iobench code
that is part of a common HPC benchmark, rewrote a portion of it to use
MPI, and did some tests. It is nice to see 16 compute nodes sustaining
1.2 GB/s write access to a single file system.
It is not inexpensive, but if you need very high very scalable
performance, it is a great design. Each rack shelf adds file system
If you want to know more about this, let me know.
