Hello, a newbie Proxmox home lab user here and starting with something that might be too complicated...
I acquired and old Nimble CS300 which is a rebranded SuperMicro SuperStorage 2027B-DE2R24L server. It has two Super X9DBS-F-2U main-boards or "blades" with up two 10 core Xeons each and up to 192GB of RAM (currently only 20GB and two 4 core Xeons are on each board). Both main-boards are attached to a HBA storage backplane and controller that gives them full access to the attached 24 drives. Obviously, having two installs of Proxmox (one on each "blade") accessing the same disk(s) is probably not a good idea.
Is there a way to make both Proxmox installs aware of each other and the attached storage so that there is no conflict between them and still be able to use all the drives for one Proxmox install with fail-over to the other if disaster strikes? Ideally, I'd like to use the compute resources on both main-boards if possible and fail-over storage and VMs to one or the other "blade" if something should go wrong. If not an HA pair that fails over all VMs and storage with one blade running everything and the other running just as an active standby in case the first fails would be great.
