Re: [cobalt-users] Managing risk.

["Daniel Pumphrey" <dpumphre@xxxxxxxxxxxxxxx>]

Just a note here:

99.9% availability is just over 8 hours of downtime - it takes most sites
this long to restore from a backup after replacing a defective drive - then
you are out of downtime the rest of the year.  I would NEVER bank on 99.9%
uptime WITHOUT raid, redundant power, etc.

Thanks
Daniel
