Which LSI card?

Hi,

 

I'm new to unRaid and I just got my unRaid trial running on a temporary PC so that I can get used to it and learn about it. The only thing missing now is an LSI card, of which I don't know much about. I've been roaming these forums and reddit and I pretty much managed to get a list of many LSI cards. What I don't understand is:

- is there a difference between them?

- is there a limit of disk sizes they support? I noticed that most people here have 3TB and 4TB drives. What about 8TB - 14TB drives? Would these also work?

 

So I found these to be commonly used:

LSI 9201-8i
LSI 9211-8i
LSI 9207-8i
LSI 9300-8i
LSI 9201-16i
LSI 9300-16i
Dell H200/H310
IBM M1015

 

 

I also understand that they need to be flashedto IT mode.

Preferrably I would like to be able to get 16 drives connected, to start with. Would you rather recommend to get two xxx-8i or one xxx-16i? On ebay in Germany the xxx-16i I can find for 100€, which is OK.

 

And do I also understand correctly, that I then need to get an SFF-8087 to SATA breakout cable, something like this?

 

Many thanks for your help!

There are, some are SAS2 and PCIe 2.0, some SAS2 and PCIe 3.0, some SAS3 and PCIe 3.0, for Unraid use with spinners (without expanders) they will all perform similar.

Yes, there's no limit with any sizes for the foreseeable future.

Some are IT mode only, e.g. 9207, 9300, but flashing to IT is easy if needed.

Whatever works best for you, in terms of total cost and number of available PCIe slots.

Yes, cables need to be forward breakout like that one, reverse breakout look the same but won't work for this.

Thank you for the help! i ended up getting the LSI 9201-16i off ebay. That way, if I need to expand in the future, I still have another PCI slot I can use.

what's your motherboard, there is a compatibility issue for those cards with consumer grade motherboard,

 

I have LSI 9201-8i (Flashed into IT mode) which is not detected in my both machines (Asrock Z270i Motherboard & Gigabyte Z68AP)

 

So be careful.
