Would this controller card LSI Logic LSI00168
Work with this cable


So I could have 4 x 4 = 16 hard drives ? If it does would performance suffer ?
That's the wrong cable. That's a multilane SAS cable.

How many drives do you need?

I wanted 10-12 but I think I will just have 8 using 2 of these

Firstly, if you're running software RAID, you want to use your onboard ports first, because their the cheapest (you already paid for them with the board - or not in your case), and because they are also the fastest ports you have.

When/if you need more drives, you would be best off looking for a card like a Supermicro AOC-SASLP-MV8 - that gives 8 ports from a PCIe x4 slot, and is much, much faster than the card(s) you mentioned above. It's around $100 + cables, so a little more expensive, but it is a very capable card, and won't bottleneck everything horribly.

I can easily run x4 in the pci-e x1 right.

Some people say the Supermicro AOC-SASLP-MV8 has no support for linux is this true ?

If the slots are open ended then yes - but why would you? What are you using the x16 for?

Well as it's supported by unRAID I think that's pretty unlikely. Oh, and SM have a Linux driver on their website too...

I was going to throw in an 8800gt to fold

But it isn't needed

I would like to announce that I think I have figured out what I will be doing. I was searching around and found a great thread on Hard Forum talking about the HP Extender.

Seems the IBM M1015 works with it and is very cheap (<$100). I can use the IBM now and when I need more storage purchase an HP extender and be good to go.

Just want someone to check my math before I pull the trigger.

yep that's a decent way to do it - the IBM cards are solid (they're just OEM LSI cards).

I'd still go with the onboard ports first before you get the card though - there really is no reason to get the card first as you just spend more money upfront and get higher power consumption for no benefit, until you have more drives than SATA ports. That should net you ~14 drives (assuming 6 onboard on the board - not checked), and if you still need more you can go with the expander if you move to another chassis, or just get another 8-port card (or cheaper) card. As you're running software RAID you don't need to use the same controller for each drive - there is no benefit to doing so, and you (potentially) limit your array speeds by doing so.

Get dual gigabyte nic card if u plan on using it as a firewall. You would need to setup your network like this. Internet > Modem > Firewall > switch > server
I personally use a p4 machine to host pfsense firewall as it reduces the complexity of the network. And that way if you need to make changes to your server your firewall will be still up

Really appreciate all the help beast

Going to start ordering the parts tomorrow.

Sounds good, I am actually now considering an atom build running untangle.
