Speed after link aggregation still remains at 1Gbps

Hi Experts,

I am having this issue that transfer speed remains at 1Gbps after aggregating 2 of 1Gb NICs together.

Hardware:  EMC datadomain, Dell R710 Server(Windows 2008 R2 ENT), Juniper Switch

The connectivity seems fine between the server and datadomain, but transfer rate has not been increased.

Please advise. Thanks in advance.

Most implementations of link aggregation use specific algorithms to spread the traffic between hosts using a mix of source and destination IPs and ports, so if the majority of your traffic is between 2 hosts and the same ports, all the traffic will flow down the 1 link

Can you confirm which switch you are using and also the type of traffic likely to be sent over the link?

Thanks Deimark,

We are using Juniper EX4200, and we are testing it by transfer a SQL database file back and forth.

So I guess this is not the right way to test, we have to transfer multiple files at a time, am I correct?
