maximum benefit from the old Hardware

Hi everybody ,

we a willing  to transform to on-premise SAP S/4 HANA ,we have already SAP ERP 6.0 EHP 5 running in place with new hardware, "not so old, purchased since 5 years", "HP proliant BL 460c G7"  but it seems that the Hardware is not suitable and not certified to run SAP HANA  .

so, what could be the best design solution for our Data center, and valid the installation option ??

one of the suggested solutions that, to perform distributed installation and to use the old Hardware to install the application and purchase New certified hardware for SAP HANA databse installation  .....is it valid solution ??

there is any other valid solution to use the old server and storage for S/4 HANA installation and get maximum benefit from them   ??

thanks

Ahmed
