Measure after the UPS in case it is drawing extra power. I seem to recall some UPS's drawing more power than they should.

Yes, you are correct. I'm just looking where else we could take this functionality.

Why not go one step further and have the ability to assign a drive as a hot spare for automatic failover provided the spare is at least the size of the failed drive?

I was only concerned that the CPU you choose is compatible with the motherboard at its current BIOS revision.

I would say go for it. Which CPU were you planning on mating with this board?

My guess is that you recently added disks 10 and 11. Prior to that it was working on filling up disk 3 to the 2nd level (3TB). My other guess is that once disk 3 reaches 3TB full it will move on to fill up one of the new disks. Of course I could be wrong.

My current parity drive is the 4TB HGST Deskstar NAS. I had issues with write speed at first while it was connected to my Areca controller but after I moved it to a motherboard connector it flies.

You probably wouldn't be able to use the SCSI drives with unRAID. I used the older PE 1600SC and have the PE 1800 as backup hardware. The server is probably something you would hide in a closet or crawl space. I wouldn't use it as a main computer. Your other system should work. It's easy enough to build a bootable USB stick and give it a shot. I don't run any VM's on my server.

I've tried this combination in the past with success. I no longer have the WDTV live but it worked for all but the highest bitrate files I threw at it even with my old unRAID server. It was my favourite media player.

It's exciting watching this thread progress. I love these Areca cards and appreciate the support they are now getting in unRAID.

I love the Areca cards, but only the ones with the ethernet ports on the back for web management. Through that interface you would see the drive temperatures and set the spindown policy. I used the ARC-1170 on my old box and now the ARC-1260ML on my current box.

I know this is an older thread but I will just say that I have this card working fine in my new server with 4x4tb drives so far. Parity took 9.5 hours @ 115.5MB/s. (WD Green drive slowed it down)

Must be the newer cards. My old ARC-1170 (24 port) with 10 drives works fine as does my "new" ARC-1261 (16 port) currently with 4 drives. I wouldn't mind seeing an updated Areca driver included with unRAID.

Once you hit 500GB free on disk one, files will start to be copied to disk 2.

I've attached a screenshot for comparison. My drives are configured as "RAID Set" (Raid0 single drive) automatically when I plug them in. I have a much older controller with older firmware but I just purchased a ARC-1280ML so I'll see how that works in a new server I'm building.

I loved my Kill-A-Watt until it died testing a fridge overnight. The fridge failed too and probably overloaded the device. For a PSU I would say 20W per drive (assuming all drives start at the same time and not staggered). The rest of the system shouldn't exceed 100W unless you're using old hardware like me. Most PSUs are most efficient at 50% load. If I have a 10 drive system that idles at 50W then I would want a (20*10+50)/.5 = 500W PSU to feel comfortable.

I realized that, after, on my server without Dynamix installed. Dynamix does not provide that screen/info. So it seems unRAID is not initializing your card properly. In your "Advanced Configuration" screen you have an option called "BIOS Selection". Have you tried any other options here? My card does not have that option.

I can help with troubleshooting now. I finally have my system up and running. 9650SE-24M8, 3 different 4TB drives so far. Precleared and parity checked fine. The snippet from my system log below shows the initial boot. Latest firmware is 4.10.00.027. The unRAID supplied driver might be a little bit dated. The LSI website indicated version 2.26.08.006 but they also indicate an "upstream" driver version 2.26.02.013 which is confusing. My current issue is that I can't get the drives to spin down. Performance is fine. My drives are labelled different from yours. Oct 17 04:33:43 Storage kernel: 3ware 9000 Storage Controller device driver for Linux v2.26.02.014.

To me, it sounds like the USB on the motherboard corrupting the drive. The drive works fine on your other computer until you plug it into your server.

The write speeds are almost indicative of a slow network connection. Are you connected at gigabit speed or only 100mbit? I'm waiting for some (impulse) ordered parts to arrive before I start building/testing my new machine.

What command did you use to generate that list? What's the response from lsmod?

I don't do a lot of Linux troubleshooting. I learn as needed. It seems unRaid doesn't detect the card. I tried 'modprobe arcmsr' and get the same response you do. The lsmod command should list arcmsr and modinfo arcmsr does confirm it's the correct driver for our cards.

When you boot, what does the bios report the firmware version of the card as being? The drive serial numbers isn't an issue. The card is probably treating each drive as a 1-drive RAID0 (Essentially JBOD). My Areca card lists the drives based on the port they are connected to...no part of the serial number is shown. I'm still waiting for parts to build a newer server around my 9650SE. I have not tested the 3Ware with large (>2TB) drives yet.

I'm still using unRaid 5 with my Areca 1170 and my syslog shows the following line: Sep 14 15:59:38 Storage1 kernel: scsi1 : Areca SATA Host Adapter RAID Controller( RAID6 capable) Does your card show up in a Windows OS?

In the card's bios (Alt-3 on boot), is it set to JBOD? I'm testing this card for a new build and unraid couldn't see the drives until I made that change.
