适用于

  • ONTAP 9
  • TCP/UDP

问题解答

  • 是的, UDP 和 TCP 流量都会计入内存较少的低端系统的 10,000 连接限制和内存较多的高端系统的 100,000(+10% 内部连接)连接限制,
    • UDP 被认为是无状态的,但 ONTAP 会保持内部"连接 ID"打开 2 分钟,以防另一个呼叫进入相同的 ip/端口组合
    • UDP CID 的生命周期至少为 4 秒,但不超过 60 秒,如果空闲
    • 当 100K 连接限制的 95% 被违反时,ONTAP 开始删除最近最少使用 (LRU) UDP CID
    • 如果新连接的速度超过删除率,新的 UDP 和 TCP 连接可能会出现间歇性无响应
