APA 是否可接到兩台不同的 core switch?

有兩台 core switch, 是否可將 HP-UX 上的兩張網卡(APA) 分別接到這兩台 core switch 上呢?

APA 是否可接到兩台不同的 core switch?

當然是可以接, 不過就只能用到APA的HA, 即網路的active, standby. 詳細請見以下說明.



Switches typically use a MAC address load-balancing algorithm.

This might make the switch a bottleneck point because the packets

from the router and from the server will contain the same source

and destination MAC addresses, thus defeating the load-balancing

algorithm for both inbound and outbound data at the server. This

condition might be acceptable if the load balancing of inbound

traffic to the server is not a concern and the link between the

switch and the router has greater bandwidth capacity than the

server's link aggregation. For example: The server's link

aggregation is composed of 100BT links and the link between the

switch and the router is a Gigabit link.



HP APA Hot Standby mode link aggregations provide high availability

network access via a primary link and a standby link. HP strongly

recommends using LAN_MONITOR mode rather than Hot Standby mode



To use APA for redundancy, it is a good idea to have them cabled

into different switches, or switch cards, however, in that case,

you cannot build an aggregate that also utilizes shared bandwidth.

那在這兩台 core switch 上需要做什麼設定呢

switch ports "MUST NOT" be configured for an aggregation.

另外, 請問 IBM AIX 是否也有 support 類似 HP-UX APA 的功能呢?
