If there are two heartbeats instead of one, that is usually the best indication of a twin pregnancy.
如果有两个心跳，而非一，即通常是最好的说明一双胎妊娠。
For example, if one of two private network connections fails, VCS has the remaining network connection and the disk heartbeat region that allow heartbeats to continue normally.
例如，假设两个私有网络通讯中的一个失效，VCS拥有剩下的网络通讯和磁盘心跳区域，允许心跳正常地继续下去。
For this method to work, the system must have two or more functioning heartbeats and all must fail simultaneously. For VCS to encounter split brain, the following events must occur.
为了令这种方法生效，系统必须拥有两条或更多的功能心跳线，并且所有的(心跳线)必须同时失效。
The low priority link prevents a jeopardy condition on loss of any single private link and provides additional redundancy (consider low-pri heartbeat along with two private network heartbeats).
低优先链接防止了jeopardy的条件是当任何单一的私有链接的丢失时提供了额外的冗余（假设低优先级心跳通过了两条私有网络心跳线）。
A null modem cable connected between the serial ports of the two systems is used to transmit heartbeats between the two nodes.
两个系统的串口之间的直连线缆用来在两个节点间传输heartbeat。
