而当在单独的内存段中创建F CM缓冲区时，在同一物理节点上的不同逻辑分区的FCM守护进程间的通信将通过共享存储器进行。

When the FCM buffers are created in a separate memory segment, the communication between FCM daemons of different logical partitions on the same physical node occurs through Shared memory.

在这种模式下，多个Power ha节点都可以访问共享卷组，这会加快发生节点故障时的故障转移(磁盘接管)。

In this mode, the Shared volume groups are accessible by multiple PowerHA nodes, which results in faster failover (disk takeover) in the event of a node failure.

因为此节点实际上仍然是活跃的，PowerHA接管会造成两个节点具有相同的IP地址，还会造成这两个节点同时试图拥有和访问共享磁盘。

Since the node is still alive, PowerHA takeover can cause both nodes to have the same IP address, and can cause the nodes to both try to own and access the Shared disks.
