這部分信息將無(wú)限重復(fù)，無(wú)法進(jìn)入系統(tǒng)。

交換機(jī)環(huán)境：萬(wàn)兆博通的，開啟巨型幀，存儲(chǔ)也開啟，并同時(shí)設(shè)置為mtu=9216，暢通。

部署需要：兩臺(tái)服務(wù)器需要開啟巨型幀，默認(rèn)1500完全OK，但是為了性能考慮設(shè)置9000.9216后無(wú)法進(jìn)入系統(tǒng)，但是存儲(chǔ)服務(wù)器使用的open-e設(shè)置值為9216完全OK，交換機(jī)也是9216.在Windows下測(cè)試沒有問題，以上所安裝的驅(qū)動(dòng)已經(jīng)是更新后的官方最新版本。特此尋找有經(jīng)驗(yàn)的兄弟幫忙看看是什么問題導(dǎo)致的。

個(gè)人想到以下問題：內(nèi)核原因，iscsi服務(wù)，或者使用的協(xié)議不對(duì)。具體還要看各位大神有什么好的辦法沒有。小弟在此謝過。

就是設(shè)置該網(wǎng)卡的MTU=9000或者=9216
