Re: [Asterisk-Users] Hardware for Asterisk
Have you experienced a hardware failure yet that you had to come back from? If you loose a drive, it is a high probability that you will loose the controller. So unless you have a add on card, or some motherboard Yes, many times. I have _never_ lost a controller when the drive went; the drive failures were all mechanical, not electrical, or not electrical to the point of causing the controller to die as well. with 4 IDE ports, you will corrupt the second drive of a mirror. If the second drive is corrupted, then you are only a hair above not having anything. If you don't trust that, check out the GOOD IDE raid controllers. You are only allowed to place 1 drive per port, and they only use 1 port on a IDE controller. If you're using two drives per channel for IDE RAID you're just asking for trouble. One drive per channel. Lose a drive, it's _very_ unlikely that you will lose the _other_ drive. I don't buy it that any truly redundant raid system is as fast in software as in hardware on a machine doing anything significant. In raid 1, you are double or more writing all data to the drives. in a read environment, it might be able to share the load out to more than 1 drive and help, but I don't expect it would be much better than a dedicated controller handling the load. Any load of a software raid solution takes processor time away from the processes it is trying to complete. So take our VoIP application, if I am spending time getting the voice recording to 2 or more drives and the software to get it there, you have significantly reduced the amount of time available to the CPU to handle the VoIP packets in a timely manner. This only gets worse as call volume goes up. If it is hardware raid, you know it will be a single write and the controller deals with the problems. I agree that software RAID of any kind adds load to the system. I never stated otherwise. I _did_ state, however, that if you're speccing a system and the system load is approaching a level where adding software RAID1 gives you appreciable load increase, you are speccing your systems far too tightly. The additional write to another drive channel for RAID1 is practically inconsequential for most systems, IMO. RAID5 with a failed system, yes you do suffer _significant_ performance loss, but I wasn't talking about software RAID5... :-) On server hardware, Dell has their own boards. IBM had their own boards. Compaq and HP also produce their own boards. Maybe they don't produce their own boards in the desktop models, but they do in the server class machines. While you can buy Intel, Tyan, and SuperMicro boards, I wouldn't consider any of the remaining ones you list as truly server class. I stand corrected; I was under the assumption that Dell was farming their customized motherboards out to a standard OEM. Maybe not by default, but if you get into the hot swap PSUs you absolutely are talking quality. Agreed. While I'll agree that a complete spare is a good idea, if you are looking for the bargains now, I don't have faith that you would also be the person who would buy 2 and leave the second untouched until failure occurs. I'll admit I couldn't leave a fully functioning machine just laying around not doing something. :-) I'm not much of a bargain-hunter when it comes to stuff that Must Worktm -- the bean-counters will bitch but when the system goes down for whatever reason and I can have it back up almost immediately it is worth every penny to them.

There IS no Hardward RAID it's all software the difference is only where the software lives, in ROM on the controler card in the RAID box or in a Linux driver. Actually, hardware RAID typically runs something called firmware (which is technically software, though it tends to be a little more difficult to alter) and offloads the task of balancing the data across multiple disks off the CPU. This is the primary difference between software RAID (which, since it uses the CPU, reduces the available CPU for other tasks) and hardware RAID. For Asterisk all you would need is a simple disk mirror at most.

I have, in fact, used many software and hardware RAID configurations, and I have had a great many drive failures. For mirroring, I use software RAID because is greatly superior due precisely for the reliance on the controller of any given hardware RAID array. Although I think it is very far-fetched to set such a high relational coefficient of drive failure to controller failure, (since I have had _far_ more drives fail than controllers) the facts that hardware controllers are both expensive (compared to free software) and rare (compared to any machine's normal IDE ports) culminates in my use of software RAID. I can stick the good drive of any software-mirrored RAID array into _any_ other system (Linux OR Windows), boot up off my trusty rescue CD with software RAID and networking, and immediately recover data or functionality. Further, this presumes that the machine which housed the failed drive is otherwise in a non-functional state. If this is a false presumption, because I have RAIDed my boot partition the system boots just fine with only one working drive. Even better, when I get the new drive, I can simply install and rebuild the array while I am on-line... a feature not all hardware RAID controllers have. _My_ horror stories are those of single brick outhouse servers which all sorts of special hardware failing out in the field with an SCA drive and no SCA backplane/controller within 100 miles.

We should have simply bought 4 600SCs (instead of 2 2550s and a 600SC), using one as a hot standby, and saved ourselves around $6000. In fact, we're planning on moving to that and selling the 2550s on eBay to improve our overall reliability.
