Hi,
此处的通信包含应用数据.
vPlex Metro的通信分为两种.一种是vPlex Metro本地集群的内部通信,这种是通过光纤; 另外一种是vPlex Metro两个集群之间的通信,可以通过光纤或者WAN.(注:集群间的通信需要注意RTT需要小于等于5ms!) 所以应该在和用户敲定方案的时候确定是vPlex Metro之间是采用FC还是IP.
以下摘自于"Implementation and Planning Best Practices for EMC vPlex".
"The I/O modules in A2 and B2 are for WAN connectivity. This slot may be populated by a four port FC module or a two port 10 GigE for VPLEX Metro or VPLEX Geo configurations. VPLEX Local configurations will ship with filler blanks in slots A2 and B2 and may be added in the field for connecting to another net new cluster for Metro or Geo upgrades. The I/O modules in slots A3 and B3 are populated with FC modules for Local Com and will only use the bottom two ports."
