Im looking at setting up a storage solution for a production service to store archival video data for a managed service
I am looking to start out this service using 3 x Poweredge R740/750's with later model dual socket Xeon cpus (64 vCPU) and 128GB ram each. For storage each...

Going to repin kernel 5.13 for now
