I'm putting together a data center and was wondering if anyone could recommend a 24 port gig switch that would house my servers and have an uplink back to the core via Fiber or copper. We have several racks and we're looking to install a switch in each rack.
There are alot of models to choose from based on your requirements. For starters, 2960, 3560/3560-E, 3750/3750-E, 4500 are all candidates.
I am a big supporter for a switch per rack in order to minimize copper runs. If this is all what you need, then yes, a WS-C2960-24TC-L (24-port) or a WS-C2960-48TC-L would be your choice based on requirement (Layer 2 switch, 10/100BaseTx, 2 dual personality 10/100/1000BaseTx or 1Gig SFP). By the way, an all-gig copper interface is also available via the WS-C2960G series.
If you want to have a Layer 2 only 48-port with stacking capability, it'll have to be the new WS-C2975-48 switch.
The 3560 and 3750 series family of switches are mostly well-known for being a Layer 2/3 switch. The 3560-E/3750-E series are capable of supporting 10Gig fiber.
The 3750 switch is also well known for it's SmartStack. It's a Cisco feature (like the 2975) that you can manage a stack (maximum of 9) switches by configuring only one switch. It's a, excuse my term, "poor man's" 6500 switch.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
