I could install ESXi 7.0on Dell R710 and R910 for homelab
But ESXi cannot detect the raid card with storage.
I know this RAID card did not support in esxi7.
Can we make driver to support raid card?
No not possible. New 7.0 only supports it "native" driver and not the old vmklinux anymore. Also the Dell 11. Gen was supportet up to 6.0 and not for 6.5(works) and 6.7(not work) because the old Nehalem and Westmare not supportet anymore and ESXi installer refuse to run.
