March 14, 201115 yr Hi, I was browsing the intertubes, and came across this: http://www.supermicro.com/products/accessories/addon/AOC-SAT2-MV8.cfm will this work in unraid? for $110, it seems like a PERFECT card, and since i have 6 onboard sata, and 2 PCI-X slots, this would fill me up just right! I currently have 1 of these: http://www.vantecusa.com/en/product/view_detail/391 which is a cheap PCI 4 port card, and it works fine.... just looking to add more!!!
March 14, 201115 yr Author maybe a simple "search" would have given me the answer I was looking for... sorry... seems like it works just fine Steve.

Keep in mind the Supermicro card is a PCI-X card. Will not work in a regular PCI slot. It needs to be a 133mhz PCI-X slot... (Which is also different from PCI-E!)
March 15, 201115 yr Keep in mind the Supermicro card is a PCI-X card. Will not work in a regular PCI slot. It needs to be a 133mhz PCI-X slot... (Which is also different from PCI-E!) This is not true. The Supermicro AOC-SAT2-MV8 is a PCI-X card, but is backward compatible to PCI. This means that it WILL work in a PCI slot. However, the bandwidth available to the card is greatly reduced. If you are only accessing one drive at a time, this should not negatively impact performance. But if you hooked up 8 drives and tried to do a parity check, you would be very disappointed in the check speeds. You really want the AOC-SASLP-MV8. It is a PCIe x4 card, and will run with good performance up to its 8 drive maximum. It requires a PCIe x4, x8, or x16 slot (make sure you have one available before buying). Note that unlike PCI-X, PCIe is NOT backward compatible with PCI slots. Also note when comparing prices, that the SASLP card requires 2 SAS to SATA cables (search eBay for '8087 forward breakout'), which are about $15 each. So the total price is actually about $30 higher than the price of the card. BTW, historically SuperBiiz has had the best prices on this card AOC-SASLP-MV8. Use coupon code PADDY15. Another card that some people have manged to find at good prices is the IBM BR10i. You can buy one for about $70, sometimes cheaper on eBay. (This card also requires the forward breakout cables just like the SASLP). It is not 100% supported by unRAID yet, but is very close in the latest beta. The only thing not fully supported is spindown, which hopefully will be fixed in the next beta. The BR10i requires an x8 or x16 slot (it will work in an elongated x4 slot, or else you have to remove the back of an x4 slot so the card will physically plug into the slot. I wouldn't recommend that but some people use a woodburning instrument to burn out the back of the slot.) A drawback of the BR10i is that is seems to be limited to 2T or smaller drives, although I am gong to run more tests with a different firmware to try to get it to fully recognize 3T drives. You can buy here. I have no idea with the one with the model number ending in 89 is more expensive. I have the one ending with 90 and works fine.

I always thought PCI-X cards were purely 64-bit.

I want to be able to get up to 20 disks.
March 15, 201115 yr I don't know. I ran the SASLP in the x16 slot and an Adaptec 1430sa in the x4 slot. That is 12 drives + 8 on motherboard = 20. Add a 2 port PCI card (or use your SAT2 for just 2 ports) and you're up to 22. That was the max I went. (I used the PCI card for dedicated preclear / emergency slot and for cache drive). Parity check speeds around 50 - 55 MB/sec. You might have luck with the BR10i in the x4 slot - just can't say for sure. I may be able to test for you this weekend but can't commit.

I just ordered the AOC-SASLP-MV8 and SAS->SATA cables last night... I get that all up and going and then decide how I'm going to add the remaining Drives... I don't even have the 4th 5-in-3 bay yet.
