oracle clusterware心跳线选择

在oracle的10GR2官方文档Oracle® Database Oracle Clusterware and Oracle Real Application Clusters Administration and Deployment Guide 10g Release 2 (10.2)有这么一句话：

 

Oracle recommends that you configure a redundant interconnect to prevent the interconnect from being a single point of failure. Oracle also recommends that you use User Datagram Protocol (UDP) on a Gigabit Ethernet for your cluster interconnect. Crossover cables are not supported for use with Oracle Clusterware or Oracle RAC databases.

意思是说，oracle推荐用冗余的内部联接作心跳，以避免单点故障，推荐用UDP协议，不支持用交叉线直联作为心跳。

你会遵守这个原则吗？
