适用场景

Brocade交换机

问题描述

  • errdump 下 F 端口上报告的 IO_PERF_IMPACT 和 IO_LATENCY_CLEAR 事件如下所示:

2022/01/20-20:49:37, [MAPS-1002], 100580, SLOT 1 | FID 128, ERROR, BROCADE, BROCADE_21.E_PORT.192., F-Port 8/0, Condition=ALL_PORTS(DEV_LATENCY_IMPACT==IO_PERF_IMPACT), Current Value:[DEV_LATENCY_IMPACT, IO_PERF_IMPACT, (10 ms Frame Delay) ], RuleName=ALL_PORTS_IO_PERF_IMPACT_UNQUAR, Dashboard Category=Fabric Performance Impact.
2022/01/20-20:50:37, [MAPS-1002], 100581, SLOT 1 | FID 128, ERROR, BROCADE_21, BROCADE_21.E_PORT.192., F-Port 8/0, Condition=ALL_PORTS(DEV_LATENCY_IMPACT==IO_LATENCY_CLEAR), Current Value:[DEV_LATENCY_IMPACT, IO_LATENCY_CLEAR], RuleName=ALL_PORTS_IO_LATENCY_CLEAR, Dashboard Category=Fabric Performance Impact.

  • 在应用程序端观察到速度缓慢的问题。
  • 同一交换机上配置了混合NPIV(虚拟)设备,这些设备的速度分别为32G、16G和8G。
  • 因此,当其中一个或所有这些设备通过该结构发送或接收帧时,交换机的速度和性能不可避免地会出现差异。
