Abstract: An upgrade process is provided to upgrade first and second switches in a converged network handling storage area network traffic and data network traffic, in which the first and second switches are coupled to a host, e.g., a Fibre Channel over Ethernet (FCoE) via distributed network links, e.g., Virtual PortChannel links or Distributed Resilient Interconnect (DRNI) links. The first switch is isolated from the host so that all distributed network links traffic associated with the host is transferred to the second switch. The firmware of the first switch is upgraded while all distributed network links traffic associated with the host is handled by the second switch. The firmware of the second switch is upgraded is a similar manner while all distributed network links traffic associated with the host is handled by the first switch.

Abstract translation: 提供升级过程来升级处理存储区域网络业务和数据网络流量的融合网络中的第一和第二交换机，其中第一和第二交换机通过分布式（例如，以太网光纤通道（FCoE））耦合到主机 网络链路，例如虚拟端口通道链路或分布式弹性互连（DRNI）链路。 第一个交换机与主机隔离，以便将与主机相关联的所有分布式网络链路流量传输到第二个交换机。 升级第一交换机的固件，而所有分布式网络链路与主机相关联的流量由第二交换机处理。 升级第二交换机的固件是类似的方式，而与主机相关联的所有分布式网络链路流量由第一交换机处理。
