Hello panzerkunst,   I am not familiar with Supermicro JBOS but you would need an external RAID controller or an HBA. R730XD External controllers that are supported: PERC H830 or 12G SAS HBA   H830: External hardware RAID controller Part# 046X6  full height Part# 4XDDR low profile ASSY Controller Card, RAID Controller, PERC H830 Adapter, 12Gb/s SAS, PCI-E 3.0, 2GB, Data sheet : [URL]     12Gbps SAS HBA : [URL] Data sheet : [URL]   Check slot priority to make sure you put it in the right slot.  page 114 : [URL]   Of course always recommended to make sure you have updated drivers and firmware.   Please let me know if there is anything else I can assist you with.
I have a R730xd (PERC H730), that I want to connect to this JBOD 4U from Supermicro. What PCIe adapter card would be compatible? I know of another R730xd owner trying exactly that via the Dell LSI 9206-16e (or a similar model) but he experienced some incompatibility (card temperature rising to 114C, fans at 100%...). Also, even once he had fixed the biggest issues (flashing the card to the newest version) it didn't seem to support 4k formatted disks. What would you recommend?
