Sun Change congestion protocol in Solaris 10

I have a client with a meshed Cisco backbone.
6500's on top, Nexus 7000 in the middle and 4500's in bottom.

Solaris 10 servers connected to the 4500's backing up to a RedHat Linux backup server connected to the Nexus 7000's. The traffic is routed from 4500 --> Nexus 7000 --> 6500 --> Nexus 7000 --> backup server.

Backup clients have 1 GbE interfaces, backbone is 10GbE and backup server has 10 GbE interfaces.

Speed is good for all backup clients but not for the Solaris 10 backup clients. They have a short spike for anything between 30 secs - 2 minutes and then falls down to about 250 kbps per save stream.

I heard this could probably be solved by changing the congestion protocol on the Solaris hosts as they are misaligned with RedHat congestion protocol. But I can't find how to change or look at that with Solaris 10???

Found an article that describes this for Solaris 11, but not for Solaris 10.

Anyone that can help me on how to do this on Solaris 10 or point me in any direction on how to solve this problem?
