christierneycfwt,   Being that the support page only shows support to ESXi 7, I am not surprised it is having driver issues. At this point I am not certain if they will be adding support for ESXi 8 on the VRTX blades, mostly due to how new ESXi 8 is it may take time.   Hope this helps.
I have three M620's and a "new" refurbished M630 in a Dell VRTX Chasis. I installed VMware ESXi 8 Custom Dell ISO on the M630. It does not recognize the Shared PERC 8 controller for the direct attached storage. I looked at the compatibility matrix for ESXi 8 and noted that the M620 and M630 blades for VRTX were absent. They are present in ESXi 7. I also see that I can download the Shared PERC 8 controller for ESXi 7u3, but not ESXi 8. It seems that Dell is still selling the VRTX, though this may be its last year. = What are Dell's plans to support VMware ESXi 8 and future editions? == Is there any way to install a driver for the Shared PERC 8 on ESXi 8? =Everything else about the installation appears to be working on the blade. I would like to get about 5+ more years out of this investment. Everything we run is super fast and has been super reliable, except for one iDRAC that became unresponsive on an M620 lately that I'm still looking into resolving. Thank you.
