I've never had issues with IDE RAID1 -- rebuild can be CPU costly but you can throttle it with the /proc interface. And issuing two async writes should not be that terrible on a system. > Raid 5 spreads the load over spindles and should take less CPU total, > but don't bet on it if it is IDE. RAID5 involves calculating the checksum/parity information (ok it's only an XOR but still) -- I've never used IDE SW RAID5. > Go SCSI or don't do RAID. SCSI is good, yes, but really, how is a decent IDE (especially SATA) drive much different from SCSI these days in terms of CPU use? -A. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
