I have an NUC5i5MYBE and want to make it load more hard disk ( more than 4).So I buy a http://www.mmui.com.cn/en/product_details1016.html M.2(PCIe) to 4 Port SATA 6G Adapter which use http://www.marvell.com.cn/storage/system-solutions/assets/Marvell-88SE92xx-Product-Brief.pdf Marvell 88SE9235 chip and plugged in M.2 2280 Module connector.
The problem is the nuc bios can't recognize the adapter.I had asked the provider about it.They said when the computer enter bios it should detect the "Marvell 88SE92XX Adapter" and show the info ("PCIe x2 5.0Gbps Mode:CPU AHCI") in screen. I just get "Not Populated" device on slot,like this:
So does NUC5i5MYBE support Marvell 88SE9235 chip? Or just the adapter is broken?
BTW my system is ubuntu 16.04 LTS, if it does matter.
Thank you for joining the community.
Let me share with you the following link for the tested peripherals on the NUC that you have; looking into the hardware tested I was not able to find an M.2 (PCI).
Reviewing the Intel® NUC specifications on https://ark.intel.com/ https://ark.intel.com/, I see that the unit supports up to 2 drives.
In order to test the M.2 (PCI) device I recommend to test it on another system, probably a desktop, to verify if the device is working properly.
Thank you for your help, Leonardo.
You mention there is no M.2 (PCI) hardware be tested. Then I google M.2 interface,find there are two kind of M.2 interface , one can operate in PCI-E mode and the other can't. So, I check the https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC5i5MYBE_TechProdSpec.pdf "Technical Product Specifications" which says "Note: Intel® NUC Board NUC5i5MYBE supports key type B (PCI Express x1/x2/SATA)" about "Storage" on page 13. I think it should support the adapter in PCI-E mode in principle.
Now I'm trying to test it on another PC. When the result come out , I will post it.
It has nothing to do with luck. You are attempting to do something that is outside of the norm and no effort has been put into testing these types of operations. Intel does not have examples of every piece of hardware that could be plugged in and thus cannot test for every possibility (doing so would be a costly endeavor and likely would raise the price of the product significantly).
Bottom line, as you have been told, Intel does not support this type of breakout hardware being used. The M.2 connector is intended to support the installation of SSD devices. Now that you have determined this to be a problem, Intel may decide to look into why it is not working, but I would think that, considering that this is occurring in a 3 generations old design, you shouldn't be getting your hopes up.
