If I recall correctly, the general feeling was that the impact was not significant since we already do most file system IO in 4k page sizes and should be fine as long as we partition drives correctly and avoid non-4k aligned partitions. Are there other concerns in the IO or FS stack that we should bring up with vendors? I have been asked to summarize the impact of 4k sectors on linux for a disk vendor gathering and want to make sure that I put all of our linux specific items into that summary... ric
