Is clustering on OES Linux "netware-like" clustering? Or is it Linux

The reason I ask is that one of my sessions in brainshare lead me to
believe that clustering in Linux (meaning Linx Clustering) required a
whole bunch of things:

Dual NIC's in each server (one for the heartbeat, one for the LAN)
a STONITH device (whereas NetWare Clustering can simply use the SBD and
LAN to send the poison pill)
