Intel Rack Scale Design (RSD) has some concepts like "Disaggregated Hardware" and allows "Node Composition", but I am not able to find what exactly this is or how it works.
EG If a rack has 4 servers, each with its own Processors and Memory and Disks and Networking, then:
Can we compose a node with some subset of hardware from a single server and make a composed (virtual?) node ? What OS will the composed node have ?
Can we compose a (virtual?) node with hardware from multiple servers ? If yes, how do the multiple servers share the hardware ?
When we make the virtual nodes, is it using some new virtualization technology by Intel ? Or is it using existing technologies like Oracle VirtualBox or VMWare ESX ?
How RSD works when the 4 physical servers in the rack have a mix of Windows & Ubuntu & CentOS installed ? Which OSes are compatible with RSD ?
(( Newbie alert : this question may sound ambiguous because I do not know what exact question to ask because RSD Documentation is sparse ; I am open to suggestions from experts ))
