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

[Arnaud Ligot]

My servers run in a datacenter, 50km away from my office... if a led
flash, if the speaker beep... I think I'll not see/hear it ...

My servers are monitored using nagios which has a plugin for software
raid... so if one array goes down, I receive a mail/sms/call/...
futher more, everything is on the same panel: raid, http servers, free
disk space, ...

I think it is better than any led flashing into the DC :-D
