Intel Xeon Phi Coprocessor 7120P And HP Proliant?

Does anyone know where I could check the HP Proliant DL 380 Gen 6 and 380p Gen8 compatibility with Intel Xeon Phi Coprocessors? At first sight it seems they fit the PCI Riser. Would services like nginx, mysql and clickhouse benefit from Intel Xeon Phi Coprocessor? I run latest Ubuntu.
