If the packets pass through a switch that occasionally garbles packets then you could end up committing erroneous sectors to disc.On the other hand, if this is a significant problem then NFS/iscsi IP checksumming may not save your data either, since the IP checksum is so weak. For large volumes of data you care about the integrity of, you probably really want an end-to-end CRC. Oops. The Ethernet CRC is end-to-end on a LAN, even if it's switched. :-) -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
