問題

  • 以下に示すように、FポートのerrdumpでIO_PERF_IMPACTイベントとIO_LANTY_CLEARイベントが報告されます。

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.

  • アプリケーション側で観察されたSlowness問題
  • 同じスイッチ上に構成されたNPIV(仮想)デバイスが混在しており、速度は32G、16G、8Gになります。
  • したがって、これらのデバイスのいずれかまたはすべてがこのファブリックを介してフレームを送受信している場合、スイッチの速度とパフォーマンスの差が生じることは避けられません。
