I did a little research, and could only find reference to 10^-12 as the target BER for 10gbase-t. I'm not sure how much this would matter though - surely people would still use the usual higher-level checksum/retransmission, no? also, from what I read, the main concern wrt BER is length-related insertion loss. obviously, if the system can manage 10^-12 at 100M, it'll have a much easier time for inside-machineroom runs (say, 15M) or in-cluster (<10 most of the time). _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
