My current switch infrastructure is three PC 2748 web managed switches where two of them are 'uplinked' to the third switch. All servers and clients are connected across these three switches using the default vlan.
I want to upgrade the switch infrastructure by introducing two stacked 6224 switches where I will be using the switches for server 2012 teamed servers, clustered 2012 Hyper-V connections (Live Migration, Cluster/CSV, etc), and iSCSI. I don't have to segregate a lot of traffic because there is not a lot going on but at a minimum I plan to put the iSCSI traffic on two separate vlans (one for each 6224 switch). I will probably vlan my Hyper-V Live Migration and Cluster/CSV traffic as well.
My plan is to connect servers, iSCSI, and firewall router to the 6224 switches and uplink the three 2748 client switches. Doing so will cause me to be port pour on the stacked 6224 switches. Here are my questions:
1. Can I use the fiber ports on both the 6224 and 2748 switches to save copper ports or does the 6224 switch require 'one or the other' port usage? In other words, do the copper ports 21-24 correspond to the fiber SFP ports 21-24 where you can use one or the other? If this is just a limitation on the 2748's then I can spare the ports.
2. Either way, it seems that I would get the best bandwidth using a fiber uplink with the SFP ports. I need detailed instructions on how to configure this properly on both switch types considering one type is managed and the other is only web managed (I have read some things about the 2748 switches only supporting static LAG, etc).
I will be configuring the 2748 switches after hours with systems down so I won't have a lot of time for trial and error before it needs to work.
