Pre-Installation Requirements for REC Cluster
Hardware Requirements:
...
REC is a fully integrated stack from the hardware up to and including the application, so for best results it is necessary to use one of the tested hardware configurations. Although REC is intended to run on a variety of different hardware platforms, it includes a hardware detector component that customizes the each installation based on the hardware present and will need (possibly minor) changes to run on additional hardware configurations. Preliminary support is present in Akraino Release 1 of REC for HP DL380 generation 9 and 10, Dell R740xd and Nokia Open Edge servers, but the primary focus of Release 1 testing is the Nokia Open Edge servers, so some issues may be encountered with other server types.
