As per the VIC 1340 white paper it provides 2 ports of 40-Gbps unified I/O or 2 sets of 4 x 10-Gbps unified I/O to each IOM. When we check our setup we can see only one connection goes to each IOM instead of two from VIC 1340 (IOM 1 shows Backplane Port 1/1 10 Gbps & IOM 2 shows Backplane Port 2/1 10 Gbps to blade 1. From blade DCE interfaces it's showing same details). Even numbered Backplane ports are not showing up or not connected to blades. Is this a limitation from IOM 2204 or with VIC 1340 itself?
Since there is a single connection between each blade and IOM how the Port Channel helps to improve the performance and what is the need of port channel here?
But our concern is why IOM & Server DCE interface shows only a single connection instead of 2? Is it because of port channel configuration? If so how can we see the 2 connections from each server to each IOMs?
