Hi all, I think I was able to find a solution for the connectivity failures. 1) For the connectivity beetween hosts and EQ box I use DELL 6248 switches. The hosts interfacese, switches and EQ box are confiured to use jumbo frames (MTU=9000). The reason for my connectivity problems was, that the DELL switches need to be configured with Maximum Frame Size = 9216. 9000 is not enougth. After changing this parameter it works. The other option is to use standard frame size on all devices MTU 1500. 2) The Broadcom adapters and there aktual driver does not support multipathing. I was able to connect with one adapter whithout problem, but I was not able to get an second connection to the EQ-Box. Thanks for your help.
