适用于

  • ONTAP 9
  • TCP、UDP

解答

  • 的、 UDP 和 TCP 流量都会导致每个节点的连接限制达到 10 万个。
    • 连接 ID (CID) 限制为 100000
    • UDP 被视为无状态,但 ONTAP 会将内部 "connection-id" 保持打开 2 分钟,以防另一个呼叫在同一个 IP/ 端口组合上进行
    • UDP CID 的生命周期至少为 4 秒,但如果空闲,则不超过 60 秒
    • 当超过 100K 连接限制的 95% 时、 ONTAP 将开始删除最近最少使用的 (LRU) UDP CID
    • 如果新连接的速度超过删除速度、新的 UDP 和 TCP 连接可能会出现间歇性的不响应
