Doing testing in our lab trying to use 2.4.x and 2.6. Trying to see how high a storage capacity can be supported above 2TB, both in partitions and file sizes. The limitation we have found in 2.4 is lack of 2TB support, (using hardware raid with 2TB+ partitions). The limitation we have found in 2.6 is lack FC HBA drivers which are needed to support large storage capacities.

You should note that software raid has smaller limits, as does the LVM. Also the 2.4 patches have seen *much* less testing than the 2.6 mainline (except possibly on the SGI Altix).
