Isn't all the talk in quality circles talking about shooting for the "Five 9's"? Which would be 99.999%. I remember seeing an email quite some time ago about how this wasn't near good enough. Maybe it wasn't 5 nines, but it was close. Started to list if this was good enough then there would be: b number of crashes at O'Hare per day. c number of babies switched at birth per day d number of... and it goes on. Kind of puts the effectiveness rating on a condom in perspective :-) Rob Berendt ================== A smart person learns from their mistakes, but a wise person learns from OTHER peoples mistakes.

Surely you jest. 99.9999% That's 31.5 SECONDS of downtime in a year. Given that there isn't an AS/400 that you can shutdown and re-ipl within 31.5 seconds you're saying you haven't IPLed this year, at all, for anything (release, PTF, crash?) Maybe 99.999%, well that just over 5 minutes. I doubt you could bring a machine down and back up in five minutes. Maybe 99.99%, that would be almost an hour. That I'd buy. Of course I have no problem getting that from a cluster of W2K machines either. -Walden -----Original Message----- From: Jim Franz [mailto:franz400@triad.rr.com] Sent: Tuesday, October 02, 2001 10:39 PM To: midrange-l@midrange.com Subject: Re: NICs - bottleneck (was Re: Dropping the AS/400 as a Web servi ng platform) Lan ports model 250s - 6 model 270s - 8 model 720s - 24 model 730s - 48 model 740s - 48 820s-30 830s - 72 840s - 96 8xx/270 features 2743 1gb eth $1820 4723 10mb eth $840 4838 10/100 eth $1800 from spring 2001 iSeries catalog btw-i prefer something more reliable than a $15 card you want the 99.9999 reliability? you want cheap? pick one (and only one). net techs call the $15 cards "throw-a-ways" and they replace a lot of them.
