SAS card for upcomming server help.

That is a 12 port card, you would be better off with the 8 port (sasuc8i) if your running JBOD its pretty good - you need to use forward breakout (SAS > 4x sata) cables to use with sata disks. Will work in any pci-e 4 (or more) port.
 
Can highly recommend Intel SASUC8i or SuperMicro USAS-L8i with LSI 1068E chip; works near-perfect on most OS. Especially if you will do software RAID or no RAID at all.

Do keep in mind the PCI-express x16 slot in your motherboard likely only has a PCIe x4 electrical connection, and thus is limited in bandwidth.
 
sub : what?? dident get what your saying?

your saying the pci-e x16 only works like a x4??? why? and how mouch will that hurt me?
 
@OP

Don't worry it won't hurt you. Assuming that board implements PCI-E 2.0, those 4 lanes will give you 2GB/sec; more than enough for 8 hard drives.
 
Not with LSI 1068E chip, that one only does PCI-express gen 1.0 or 250MB/s per lane. With 4 lanes that is 1GB/s full duplex; still alot. But originally it is intended for PCI-express 1.0 with 8 lanes, meaning 2GB/s full duplex.
 
FYI, the PCIe x16 slot on the Zotac NM10-DTX is only x1 electrical. That's a significant bandwidth limitation, depending on what kind of speed you're looking for.
 
That's even worse, 250MB/s total bandwidth for 8 devices. Any URL for confirmation epimetheus?

hmm so what your saying is that MB blows :D

what about this zotec insted : http://www.edbpriser.dk/Product/Details.aspx?pid=781083 will that work better with the card that sub.mesa say??
Click to expand...

That board is actually worse, since it only has a PCIe x1 physical slot. The Intel card that sub.mesa recommended wont physically fit on that board.

Edit: Well it might fit, but you would have to cut the back of the PCIe slot, and it still only be x1 electrically.

Edit 2: To get anything more that PCIe x1 in the Mini-ITX form factor, you're probably going to have to get away from the Atom processor and chipsets. I just built a Mini-ITX with an i3-540, Intel DH57JG, and an Antec ISK300-150 case. I haven't seen it pull more that 70W at the wall.
 
epimetheus : that sucks.. the thing is i wanna keep it at low in power as i can with out dropping a crazy ammount of cash in it..

i need a tower that will take 12 hdd's in it as well isnt really sure what to look for there but have to be some thing i can get in denmark.

Sdadept : that card looks really good as well but is x 3 the price and cant corrently affort a card like that :(

the plan is to run it as a non naid systes so i can just add hdd's when i need more space really.

what about a gigabyte card?? non of them will work with atom??
 
AMD or core i3 with onboard IGP should be about the same idle power as some less recent Atoms, but with significantly more processing power when needed.

AMD has the nice Athlon 250u; the 'u' prefix stands for ultra-low power, and is among the lowest TDP of AMD desktop chips; 25W. The new 'Ontario' CPU that AMD will release in H12011 might be considered a true competitor to Atom; only 5W more TDP but twice the processing power and a much better GPU.

For home-servers, don't look at TDP too much! TDP can be misleading. A 65W TDP CPU which idles at 2-3W is very power efficient too! Your NAS will be idling 99%+ of the time, all you need to look for is idle power!

So look for power efficient motherboard and chipset and cpu. There are nice boards for both Core i3 and AMD platforms. If you want 12 disks then you need 4 onboard SATA + 8-port controller like the Intel/Supermicro one based on LSI 1068E chip.
 
sub : any chance u can point in the right way on mb's that i can get in Denmark and dont gonna cost me a million?

but yeah i know but i like to 6 sata on the mb so i can use one of them for DVD and one for OS and the the sas card for the 8 disk's.
 
@OP

Have a look at this and its variants. It's mATX and supports the Clarkdale i3 and i5 CPUs for integrated graphics.

I'm actually looking at one of these for a combined media server/HTPC build.
 
Parity : looks nice but the MB + CPU will ´make it x2 the price :( but if that is what i have do i guess i do it :(

Sub : will that MB work the intel card u posted? and will i get good spd out if it as well?
 
I think it has full PCI-express x16 due to the modern chipset; meaning you will have full bandwidth with a SAS controller. And yeah the Intel/SuperMicro controllers should work on all PCI-express ports and all OS. The only thing that is uncertain is boot support which requires interrupt 19 capture support in your BIOS; most retail boards support this. If you boot from another device then your controller does not need to be supported by the BIOS.
