HP NIC Teaming

I am the in process of moving into a fully redundant Data Center from a very inadequate make shift Server Room. During this process one of the steps is to team the NICs for fail over. No big deal but, however I have a "HOG" of a database server which needs to be teamed for performance and fail over instead of just fail over, basicly I want to team 2 teams. I did some research and found out that HP had "at one time" an advanced pack add on for their teaming utility, but they discontinued it for the ProLiant line of servers. This option was called "Intelligent Networking Pack" and I wanted to use it for "Switch-assisted Dual Channel Load Balancing" which I have been told that HP will not support this on the ProLiant G5 line anymore. That really sucks! If anyone has another solution for me please drop a line.

I pulled this off of the HP NIC Teaming White Paper, it's a better description of what I'm trying to accomplish.

Switch-assisted Dual Channel Load Balancing, referred to as Dual Channel or a “team of teams”, is a special team type designed by HP to accomplish everything that NFT, TLB and SLB team types accomplish all in a single team type. Prior to Dual Channel, an HP ProLiant Network Adapter Teaming user had to choose between inbound load balancing (SLB or 802.3ad Dynamic) or switch redundancy (NFT, TLB). Dual Channel allows the user to create two teams, called groups, inside of a single team. Each group (A or B) is assigned one or more teamed ports. Also, each group can be connected to a different switch to provide switch fault tolerance. Full inbound and outbound load balancing is provided across both groups. Should all members in one group completely fail, the team remains available via the other group. If the groups are connected to different switches and one of the switches fail, the team remains available via the group attached to the functional switch. Switch-assisted Dual Channel Load Balancing requires activation with a license key and is part of the INP upgrade for HP ProLiant Network Adapter Teaming.
