bedpan Posted December 7, 2015 Share Posted December 7, 2015 Hey folks.. Got Unraid up and running well. Using an Asus P6T6 WS Revolution Mobo. It has 8 onboard sata ports which I have full. Thinking about adding an expansion card of some sort. I have an old 9650SE-24M8 card that I have been playing with. Its been a bit problematic so I think I will just replace it. Locally all I can find are some cheap PCIE 1x cards that I am sure performance will be an issue. Looking at the hardware list I am having a hard time finding anything local or with reasonable shipping. So I have fallen into trolling ebay and getting lost in the options. There are so many controllers talked about here and I just want to make it works and delivers decent (or better) performance. Hoping for 4+ ports and in the end I will investigate distributing the drives, parity and cache drives across controllers to maximize performance. Was thinking about ordering the Supermicro AOC-SASLP-MV8 off of ebay. A few for about $30(USD) with $20(USD) shipping to Canada. Then I will need a couple cables. Best option I have found is Newegg.ca for about $35(CAD) for 2 cables http://www.newegg.ca/Product/Product.aspx?Item=N82E16816116097&_ga=1.84011993.1501904548.1427412111 So about $100(CAD) or $76(USD). Thoughts? Decent bang for the buck or is there a better option I should be looking at in this price range? Should I spend a few more dollars to get better performance? Sorry to beat a dead horse. I have been running in circles all night trying to figure out what to order. My experience is so limited its tough to choose. Many thanks in advance! Mike Quote Link to comment
Squid Posted December 7, 2015 Share Posted December 7, 2015 Either the SASLPMV8 or the SAS2LPMV8 will be fine (The SAS2 will give you a little bit more performance for not too much more money -> it's only ~$20 more brand new at newegg.ca). On my SAS2LP on single drive reads I can hit the maximum the drive can offer for speed (200MB/s), and on parity checks (with some drives only rated at 150MB/s max) I get parity check speeds of up to 130MB/s The SASLP will be a bit slower Quote Link to comment

I cannot seem to find the sas2lp in the same price range as the saslp on eBay. No used available it would seem. How does the IBM m1015 compare? It seems to be in the dangers price range. Any others I should consider? I am mobile right now but will try and answer this myself when I can. As I was laying in bed last I was pondering options. I should check with my work to see if we have any servers going for recycling. Maybe score a chassis and our raid card. Also I should try and sort out the 9650SE-24M8. The 9650SE-24M8 seems to had been working. Anyone know performance wise how it would compare? A few things I noticed when I was toying with it that made me nervous. No smart data available The drive names where being partial zeroed out as if it is not fully reading the serial numbers Speed seemed quite slow Preclear plugin would not work on this controller Thanks again Mike Quote Link to comment
JorgeB Posted December 7, 2015 Share Posted December 7, 2015 I would also recommend the SAS2LP, the SASLP with 8 disks will limit your parity checks to ~80MB/s. The M1015 (or Dell H310, same LSI chipset) are also very good options, note however that they have to be flashed to IT mode for Unraid (Sticky thread on this subform) Quote Link to comment

No concerns on flashing. Looks easy enough. Quote Link to comment
JorgeB Posted December 7, 2015 Share Posted December 7, 2015 SAS2LP and IBM/Dell are very similar, with no other bottlenecks both can do 300MB/s+ with 8 disks. SASLP about 80MB/s with 8 disks. This only applies to parity check/syncs or disk rebuilds, for normal read/write operations all will be similar. I did some test with these and other controllers on this thread: http://lime-technology.com/forum/index.php?topic=43026.0 Quote Link to comment
mrmarkfr Posted March 16, 2016 Share Posted March 16, 2016 Does the M1015/H310 have any capacity issues(2.2TB max??) Quote Link to comment

BobPhoenix Posted March 17, 2016 Share Posted March 17, 2016 Does the M1015/H310 have any capacity issues(2.2TB max??) Running 6TB drives on mine. Quote Link to comment
Dephcon Posted March 20, 2016 Share Posted March 20, 2016 keep in mind that the SASLP(SAS1) doesn't support 3TB+ drives, you pretty much need to buy SAS2 cards these days. Quote Link to comment

Ran 4TB Seagate drives on mine so I don't think this is true. Ditto. If you have plenty of pci-e slots, some cheap 2-port pci-e 1x cards can be a good way to go - what specifically was your concern with performance with 1x cards? Quote Link to comment
Dephcon Posted March 22, 2016 Share Posted March 22, 2016 hmm i guess whatever SAS1 card i was using was crap Quote Link to comment
Squid Posted March 22, 2016 Share Posted March 22, 2016 hmm i guess whatever SAS1 card i was using was crap probably a Br10i. Very commonly used, but limited to <2.2 Quote Link to comment
