Motherboard RAID Controller

Hi everyone,

 

Firstly, I'm new to UnRAID and am looking at configuring my first server shortly. I have a question that I'm looking to have answered before purchasing any hardware:

 

1. It appears that UnRAID is software based. Is this correct?

2. If so do i require a RAID controller or simply a bunch of sata ports?

3. I'm looking at a new motherboard that states it does not support RAID, will this be an issue?

 

Sorry if this has been asked before, i did have a quick look at the forums for similar questions.

 

Thanks for your assistance :)

Unraid is purely software, and doesn't play well with RAID controllers. Plain HBA controllers are much preferred, if you find a RAID controller that can be flashed to IT mode instead of IR mode, those generally work well.

 

Avoid Marvell based disk controllers, LSI are preferred.

How many disks will be in your server?  Depending on how big the array will be, you may be fine with just motherboard SATA ports.  Many motherboards (especially "server" motherboards) can have 6, 8 or more SATA ports and or/NVMe slots.

 

For many years, I never expanded beyond the 8 SATA ports my MB provides.  One Parity drive, 4 data drives, 1 cache drive and an optical drive for MakeMKV left me one free slot.  As I plan to expand the number of data drives and cache drives, I need to move beyond that and have added an LSI-based HBA card in IT mode with support for up to 8 more disks.

 

One thing to keep in mind, especially of you go with an older LSI-based HBA (many cheap ones can be found on eBay), SATA SSDs should be attached to MB SATA ports as they support TRIM operations.  Many of the newer LSI chipsets now support this as well, but, the older ones do not.

Thanks guys for your prompt advise. I will be looking at the following setup: so suspect the onboard SATA ports/ specifications should be adequate 

 

2x 6TB WD Red Storage

1x  6TB WD Red Parity Drive

1x  240GB SSD SATA Cache Drive

 

ASUS Prime H370M-PLUS Motherboard

Intel Core i5 9400

 

This is for a Plex server :)
