The latter can easily be redundanized and are in any well-designed rack-mount box, and by employing SCSI disks or at least the more expensive IDE disks, you can get good scores there as well.
On our 14 server machines we've had 4 disk failures (only 1 of them in a non-RAID, so that was downtime - but we keep spares, so that was only a couple of hours) and zero fan failures since jan 2001, when they were taken into production. Of course, the hosting environment (21.5 deg. centigrade, controlled humidity, filtered air) will help a lot here. I can imagine getting 96% if you put your server in an office environment where people smoke and the cleaning lady now and then bumps against it with the vacuum cleaner. YMMV. Most downtime has been due to OS-level issues. And that's because we're trying to squeeze too much out of too little hardware ;-). The boxes that have been doing just one or two things typically go down only for an OS upgrade. -- Cees de Groot http://www.tric.nl <[EMAIL PROTECTED]> tric, the new way helpdesk/ticketing software, VoIP/CTI, web applications, custom development _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
