Ethernet or FC connection ??
If so it would be possible to build an PDP-11 who is datacenter-
compatible today year 2019 ...
One requirement for todays datacenter (for some owners at least) is the
ability to directly connect the system to the storage system (ie
FC/SCSI or IP/iSCSI.)
Hint: with that requirement as far as i know it an ARM device in the
form of a Samsung S9 can't be data center compatible....
