1, Netapp 網(wǎng)卡設(shè)定類別:
a. single mode 通常2個接口作single mode,分別連接外部2臺交換機,同一時刻只有一個端口有數(shù)據(jù)流.(NA自己的single mode冗余作用)
b.multi mode 通常2個接口做multi mode,與外部1臺或stack 2臺交換機相連,同一時刻,2個端口都有數(shù)據(jù)流.(雙端口線路冗余)

c.lacp mode 通常2個或4個接口作multi mode 與外部1臺或stack2臺交換機相連接,同一時刻所有端口都有數(shù)據(jù)流.(雙端口線路冗余)
d.single與multi mode 混用,通常4個接口,可以先2,2multi 在做single mode,用于同外部兩臺交換機相連,統(tǒng)一時刻只有multi mode 的那2個端口有數(shù)據(jù)流.
所以看出,如果條件允許,使用stack 交換機是最好不過,否這只能靠STP來冗余
