适用于

  • Element 软件
  • H 系列存储节点,具有支持 25GbE 的 NIC
    • H610s
    • H410S
    • H300S/H500S/H700S (已弃用)

解答

具有支持 25GbE 的 NIC 的 Element 存储节点不会自动协商到该速度(即使连接了 25GbE SFP+ 收发器也是如此);但是,它们连接到的交换机可以自动协商。
 
使用 10GbE SFP+ 收发器的存储节点可以连接到使用 25GbE SFP+ 收发器的交换机端口,因为交换机负责自动协商连接速度;但是,在这种情况下,交换机将仅协商到 10GbE 。
 
理想情况下,在交换机和存储端均应使用 10GbE 收发器,但在任何情况下,协商均应在交换机端进行。
