I've got a Dual Xeon system Digium Quad T1 and an Idle T1 circuit that I can experiment with. I've been wanting to use Redhat with software Raid 1 on an Asterisk server.
Has anyone had any experience with software raid and Asterisk? Also, if the software raid doesn't play, any recommendations for a hardware based IDE Raid controller and suggestions on best practices for setting up the disk partitions (2 X 40 GB. Maxtors) for a mirrored environment would be appreciated.
Thanks all
I've had no luck with software RAID in Linux. Using RAID1, recovering a drive seems to peg the processor, and the recovery lasts for over 16 hours for 160GB disks. I can't even imagine what it is doing during that period. I played with the /proc values, but I wasn't able to reduce the CPU utilization.
Needless to say, with 90-100% CPU utilization, voice quality goes down the toilet--the system was totally unusable until the recovery was complete.
I've gone to the 3Ware 7006-2 ($100). This card has two IDE ports (other cards have four, eight, and 12). To the system it appears as a SCSI controller with one drive. Drive recovery is handled on the card.
I have an eight port card with 200MB drives on my database machine (RAID5), and it works quite well. 1.4TB of disk. I've lost a drive and the machine continues to operate.
I'm sorry to hear about the Promise chip because that is what is on the newer Tyan mother boards. For a 1U or 2U cabinet, I don't have the luxury of a bunch of PCI slots (the two slots are occupied by T405P cards), and I need to use the on-board raid. Does anyone else have any experience with this.
