Disk capacity has been increasing faster than IOPs and the trend is continuing. This is making it harder for enterprises to effectively use large-capacity, commodity disks. Many businesses are going to reach the seek barrier after which they will not be able to use the full capacity of the larger hard disks. Their applications approach the point where they become spindle limited in a sea of capacity. There are many techniques for helping businesses reduce IOPs/GB: - Make SSD caching for hard disks a standard feature - Seek vs. memory tradeoffs - Tune file systems more aggressively for seek reduction - Improve the interfaces between disks and block layer - Improve writeback - Seek vs. durability tradeoffs - Seeks vs. capacity tradeoffs It will be interesting to hold a discussion on this subject to raise the awareness of the problem and to brainstorm additional potential solutions. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
