If you're talking just streaming some big video files, even a single FAS960 will have no trouble saturating a 2.5Gb/sec link. For example:
filer04*> sysstat 2
CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache
in out read write read write age
12% 2664 0 0 557 406 44 0 0 0 34
73% 27430 0 0 2878 87207 13236 0 0 0 34
100% 37447 0 0 6597 317242 2823 0 0 0 34
100% 37265 0 0 6390 315388 3120 1741 0 0 34
100% 37453 0 0 6386 316227 2518 0 0 0 34
So over 300MB/sec even with 8K blocks, and this is a single 960. I generated that throughput with 6 boxes reading 6 seperate 2GB files. I was actually surprised to see that on a dual-Opteron 246 box I was able to read a stream from the filer at about 92MB/sec.
So I guess today's ultra-fast PCs can indeed move some serious data. Of course, if you don't have a badass NetApp filer you may need to think up some other way of delivering that kind of data rate from disk. Otherwise as someone else suggested a pile-o-RAM and a simple tcp server would do the trick.
