Great, so as long as I go for dual link, in theory I should be able to run 12 (8 internal and 4 external) Hard drives from it all running at full speed, 150mb/s?

Oh, thanks Johnnie.
I was reading the specs on the HP website and it mentioned (whoops 1TB not 2TB):
CapacityGiven the increasing need for high performance and rapid capacity expansion, the SAS Expander Cardand the SA-P410 or SAP410i Controller offers:-
Up to 14TB of total storage with 14 x 1TB 3.5-inch SATA MDL HDD
-
Up to of 7.2TB total storage with 24 x 300GB 3G SAS 10K SFF DP ENT HDD
Does the card work straight from the box, or do I need to fiddle with it like I need to with the M1015 to get it in IT mode?
Edit: Do you know if this card is SAS v1 or SAS v2? I will only ever use hard drives with the M1015 and the expander card, using the onboard SATA connections for SSD.

Oh hang on a mo. If I go the expander route, I have just come across this https://www.ebay.co.uk/itm/HP-24-Bay-SAS-Expender-Expander-Card-487738-001-468405-001-External-Internal/222966046815?epid=19014650362&hash=item33e9cfe05f:g:FhoAAOSwA4Va4jvl
Anybody know if this will work with unraid as it has both internal and external connections and would be ideal in my situation.
Edit: Apart from of course the 2TB limit for the hard drives, grrrrrrr!
I may well go the purchasing a 2nd M1015 route as I know this works and they can still be had quite cheaply.

You have confirmed my suspicions about the Marvel controller so I will look at the HBA route instead. I currently have a brand new IBM M1015 HBA that hasn't been flashed to IT mode yet and is still in its packaging. However, the intention for this card was to give me an extra 8 ports (i have a 16 bay server case with eight of the bays already filled). With what you have written in mind, I could go one of three routes from here:
1) Purchase a second IBM M1015 card
2) Purchase an expander to run along side the existing M1015 I already have, something like the IBM-46M0997 expander card, then purchasing the external SAS adapter as in my OP
3) Find a SAS card that has 8 internal ports and 8 external ports. I had a look last night for one of these, but they seem to be rare although I did come across a couple, they were just so expensive
If the IBM-46M0997 expander card is compatible then I think this would be the route I would take, unless someone comes up with a reason not to go for it? At least this negates the problem of which cable to go for as it would just be a simple SAS to SAS cable required.

I am about to purchase one of these for external back up:
https://www.startech.com/uk/HDD/Enclosures/4-Bay-Rackmount-Enclosure-for-SATA-SAS-HDDs~SAT35401U
This will be filled with 4 x 6TB hardrives and I will hopefully use crashplan (unless anyone recommends anything else) to backup my unraid server fully.
I have an Asrock EP2C602-4L/D16 motherboard, but am currently using all the sata connections for all the hard drives in the unraid array, and am left with 4 x SCU ports which I understand I can use as normal SATA ports (although the controller is a Marvell?)
So, to connect the above JBOD device to the 4 SCU ports on the mother board, I am contemplating on using one of these (spare port just in case I purchase another external enclosure in the future):
I will then use a Mini SAS SFF-8088 SAS cable between the Dual Port adapter and the external enclosure, that bit I get. The bit I'm stuck on is which SAS 36Pin SFF-8087 cable I need to connect the Dual Port adapter to the 4 x SCU ports on the motherboard. Is it a forward or reverse cable I need? In the back of my mind it is a reverse cable I need, but I just wanted to check before I went ahead and made the purchase.
Cheers

Ok, just checked the log in the IPMI plugin and it seems that I too am still getting a false positive (hopefully), but it only appears on one of the CPU's in my case:
However, at least the IPMI plugin is keeping the fans under control and I'm not experiencing what sounded like a jet engine every 10 or so days now.
Yep, just checked all 273 entries, and all are showing the spike of CPU_BS1 only.

Hi Guys,
I know this is an ongoing thing with this motherboard, indeed I also experienced it at one time. I use 2 x Intel® Xeon® CPU E5-2670 0 @ 2.60GHz and every now and again I would get the 100c spikes as mentioned, or the fans would spin up to full and only a reboot would solve the issue.
However, by some miracle I found a cure for it and I'm not sure if anyone else is using this, but I installed IPMI plugin and set up thresholds and since then I haven't' experienced the spikes or the fans running at full speed. Just to give you an idea, the fans would spin up to full every 10 days or so and the server required a reboot, but I've now been running the IPMI plugin for several months and not once have they spun up to full speed and stuck there. Ok, due to the thresholds I have setup they do spin up faster every now and again but that is due to the ambient temp rising, but they never go full pelt these days.
I'm so glad I found a solution to this as it was driving me nuts when the fans spun up to full speed, sounded like a jet engine taking off.

Hi,
I installed the NO-IP docker yesterday afternoon, filled in the details inf the config file, NO-IP then created the no-ip2.generated file and everything appears to be working. When I first started the Docker it then updated my NO-IP account with the IP address I am running on, but it appears it hasn't updated since. I logged into my NO-IP account, went to the manage hostname page, and clicked on the info icon and its showing last updated 22 hours ago i.e. when I first started the Docker. It hasn't updated since.
I have checked the Docker log and cannot see any problems and I see this being generated every min:
Process 18, started as noip2-x86_64 -c /config/no-ip2.generated.conf, (version 2.1.9)
Using configuration from /config/no-ip2.generated.conf
Last IP Address set ***************
Account ***************
configured for:
***************
Updating every 30 minutes via /dev/eth0 with NAT enabled.The Last IP address set is my correct IP address, the Account shows the correct email address, and the configured for show the correct hostname.
Am I missing something?

Silly question time, more curious than anything else, but you mention you are running 9 internal and 5 external, yet the expander card only has 1 external output. Having read time and time again that 1 SAS port = 4 SATA connections, how are you running 5 external disk from the 1 port?
As mentioned in my Op, I am contemplating purchasing a Startech SAT35401U, which has a SAS port but may eventually purchase a 2nd one for backup purposes and am intrigued into your 5 disk external setup hence the reason for wanting two external SAS ports. However that can wait for now as the 1 Startech unit will be enough for a couple of years for backup.
