[asterisk-users] Saftware RAID1 or Hardware RAID1 with Asterisk

[Steve Totaro]

I thought that was what the flashing LEDs on the front of the server's 
HDs were for (besides showing activity). Some I have seen also have an 
LED near the power button to indicate HD problems.

I guess if you are building your own boxen and not using enterprise 
grade servers, this is not the case.

Thanks,
Steve Totaro
