Check out these papers from Fast08, they're based on NetApp data for more than a million disks: http://www.usenix.org/event/fast08/tech/full_papers/krioukov/krioukov.pdf http://www.usenix.org/event/fast08/tech/full_papers/bairavasundaram/bairavasundaram.pdf http://www.usenix.org/event/fast08/tech/full_papers/jiang/jiang.pdf And, finally, this one makes you wonder how Linux storage works at all: http://www.usenix.org/event/fast08/tech/full_papers/gunawi/gunawi.pdf Internal checksums for small files can be defeated for lost writes. I take it that your external checksums are stored in a totally different place? In which case you ought to be pretty well covered. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
