RE: NICs - bottleneck (was Re: Dropping the AS/400 as a Web servi ngplatform)

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 :-)

>you want the 99.9999 reliability?

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.

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.
Anyone who buys raid drives, mirrored systems,24x7 uptime & a working DR
plan to run a real shop has no business with brand-x throw-a-ways.
