We have a Cisco Small Business SG300 28 port switch (layer 3).
We're adding several servers (VMware ESXi) to this environment, and this switch does not have enough ports to support both servers, so we are looking to buy an additional switch.
1. What kind of switch should we buy: Layer 2 vs Layer 3?
2. If we went with a layer 3 switch, would the physical switch connectivity to one another be the same as if we bought a layer 2, switch -- Cisco EtherChannel?
3. In terms of the switch config, what major config differences would there be if we went with a layer 3 switch?
1. Since we already have a layer 3 switch, we don't need
to buy another because a layer 2 switch would forward all traffic that needs to be "routed" to the existing layer 3 switch -- using "CiscoEtherchannel" -- I believe. I primarily work with ProCurve switches, so in HP terms I would use a Trunk.
