Do we use dedicated ISL ports for connecting a pair of SB7800 switches?
Any special connectors?
What’s the max distance of fibre between these two switches?
How many fibre cables do we need?
The plan is to place one new switch in a cabinet where existing servers reside and connect that switch to wherever the DC guys can place the second IB switch since it will connect to storage controllers and new servers. This is temporary to allow migration. At the end both switches will reside with the new servers and storage. This is to avoid spending a lot of money long lining existing servers to the new switches since the longer cables are more expensive .
