Can you explore HBA mode on H730. You can refer below links for details [URL]  [URL] 
I will be buying: 1x Dell R6415 8bay 2.5" 1U with iDRAC Enterprise1x AMD EPYC 7551P 32CORE 2.00GHZ128GB RAM1x PERC H730P 2GB cache Mini Mono1x Enterprise SSD 400GB7x 2TB 7.2K 12G SAS 2.5" 2x 550W PSU1x Rails I want to install proxmox operating system on the SSD and then using proxmox admin create a ZFS option for storage using the 7x 2TB drives for running virtual machines and containers. Proxmox specifies that ZFS CANNOT be run on hardware RAID of any sort so with this new server can I disable 100% the RAID option and let the disks be seen in the operating system as single disks? Even JBOD cannot be used also as per a post in proxmox forum: "It depends...often those raid controllers create a JBOD or single disk raid0. This is not what you want with ZFS. You want it to operate in initiator-target mode (IT-mode) so a dumb HBA without any abstraction layer between ZFS and the disks. See here why using HW raid with ZFS isn'T a good idea: [URL] and Tuning/Hardware.html#hardware-raid-controllers So you better verify that the raid is really entirely disabled. There are some PERCs that can be crossflashed from IR-mode to IT-mode, but it looks like your PERC 730 Mini is not one of them: [URL]" Because I dont have the server yet I cannot test any settings in the BIOS so I was wondering if anyone else has any experience with disabling Hardware RAID 100% and using proxmox? Any help would be greatly appreciated. Regards James
