I know exactly what those expected and acceptable level you are talking about. And I have adjust and monitor them at both production and prototype level. It is either humping along or fall on its face and nothing in between. If you tell me you have indeed log those errors and get 10e-12 BERT my hats off to you. I have been puzzled by this 10e-xx claims for a long time and indeed very interested in what others do. ________________________________ From: Alan.Hiltonnickel@xxxxxxx [mailto:Alan.Hiltonnickel@xxxxxxx] Sent: Fri 6/30/2006 10:57 PM To: Chris Cheng Cc: si-list@xxxxxxxxxxxxx Subject: Re: [SI-LIST] Re: Fibre channel interconnect margins You might want to re-check that. Yes, we have the same CRC checks and flags. But after error rates get to the "expected" or "acceptable" levels, most folks turn off the error reporting and let the software and hardware do what it's designed to do, because the system is tolerant of errors. That's the purpose of CRCs - to make systems more robust, not to make the customers help you debug your systems. Otherwise, it sounds like you're telling us that you have invented a way to design equipment where randomness does not happen. Hope you got a patent on that! ;-) Alan ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
