Actually Im having problems accesing to a NAS Storage, a capture of Wireshark shows that they are a lot of ACK retransmitted.
A review of the interfaces in the path to the NAS shows a lot of output dicards in a connection between Nexus 7k and Nexus 5k using vPC.
Any idea about how to resolve the problem of output discards
