Imagine I need to provide a reliable network environment between two mainframes.
Basically there is an 'intra' NIC communication between the two mainframes. Such 'intracommunication' NIC could be connected in an isolated switched environment as long that supports 1GB. The idea is, instead of using a VLAN in our existing production environment in order to allow communication between the two mainframes, folks would like to use a small switch instead, totally isolated from the network to provide such intra-NIC communication service between the two mainframes. My questions are:
a) Do you agree that typically by keeping a separate switch (perhaps a new layer 2 2900 XL ?) I could provide a more reliable environment than if I plug the servers onto new VLANs in my existing 3750 switch? Note that my 3750 switch in production is not a stackwise. It is just a standalone one.
b) Can a small 2900XL switch (8 ports?) do 1000MB? Also, I recommended that we use copper instead of fiber for this.
c) In the past I heard people talking about problems with teaming itself. I am wondering whether if I just use one Gigabit NIC, copper, I will be offer. Again, please let me know in case the layer 2900 XL switches do not handle gigabit.
Your insight is very valuable. Thanks.
