I’m will like to know which HBA will be recommended to use with Unraid on the HL15 to get the best performance. Currently I use 2 LSI 9211-8i but I will like to have only 1 HBA instead of 2. I know that HL15 has a backplane with miniSAS 8087 connectors that will work with my current setup of 2 cards but I’m trying to safe one of the PCIe slots for another usage.
The HL15 backplane has SFF 8643. You can buy LSI 9305-16i or LSI 9400-16i for about the same price used. LSI 9300-16i goes for much less, but runs hotter and needs more power, however in my opinion it’s insignificant, since you will pay a lot less in the next 5 years for electricity then the extra costs of the other two cards with SFF 8643. You can go with two SFF 8654 → 2x SFF 8643 cable if you buy LSI 9500-16i or LSI 9600-16i, they work too but much more expensive.
Just to clarify balika011’s response. Technically the backplane has four SFF 8643 connectors, but when you buy the “chassis+backplane” or “chassis+backplane+psu”, included in the price you will be able to select a set of cables based on how you plan to connect the backplane to your mobo and/or HBA. I think there are seven different options (A through G) with various combinations of 8087/8643/8654/7pinSATA connectors on the non backplane end. You just need to select the correct set depending on the type of connector the 16i card you get has.
Yes, exactly. I gone with the SFF 8643 to SFF 8643 option because I plan on using an LSI 9400-16i. If you want to go with LSI 9600-16i or pretty much anything else you can select the right cable when you check out.
I use LSI 9500-16i and LSI 9500-8e in each of my HL15s but note the other comments saying that the cabling set you ordered will be a factor. It can obviously be swapped too if needed (which will add some to the cost).
