I'm familiar with that chassis so I'll take a stab at this one. (I own the RPC-4220) I am just only presenting the hard drives to the operating system (ESXi) vanilla, meaning as 4 TB drives for 24 QTY. When using this method, a RAID controller is not required for implementation. A HBA (Host Bus Adapter) will suffice and they are significantly cheaper. ...

And they are different for different disk types. Moreover there are some limits per VM Size. So for the best result you should choose right VM Size, disk type and number ...

This does seem kind of round-about, do I have any better options? Your general idea is spot-on. I would personally suggest using ZFS with Solaris or FreeBSD, but mdadm might also work. Maybe though you don't get all the advantages I write about in this post, so take that as a disclaimer. This post will be quite long, I apologize in advance for the wall of ...
