Cisco 3560 Core Switches

Looking for a second oppinion here. Customer has a couple data closets (each tied to copper in various parts of the building) and would like to use Cisco 3560 as stackable switches in Trunk mode (no spanning tree) for failover and redundancy. Please the the attached diagram. Will the 3560 accomplish this, and what Image is recommended?

To stack using the 3750's you don't need to have the same IOS image but you do need to have the same level of IOS (LAN only, IP), you can't stack a LAN only image with a IP image and vice versa.

Clustering works across multiple versions and multiple device types, further up in the link I pasted above are some caveats around which devices should be cluster manager, but in your setup I don't think it will be much of an issue.
I'm not positive but i thought 3745 was the only stackable switch? Unless you mean just connected with a fibre or cross-over cable.
3560's don't have the "stack" feature, that is only supported on the 3750's.

You can cluster the 3560's but I don't believe that is what you're trying to achieve, see the following link for the differences between a cluster and a stack:

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Yess you need 3750 Switch which supports stacking.

As stated previously, you will need the 3700's to do what Cisco calls "stacking". However, you could connect the switches with the gig ports and put them in a cluster. Instead of the interconnects being backplane speed, they'll only be 1gbs though.

Is switch1, switch2 and client switch1 going to be forwarding traffic in the same VLAN/broadcast domain? If so, you'll need spanning tree.

Is there a particular image required to cluster on the 3560's or Stack on the 3750's.
Don JohnstonInstructorCommented:
No. All 3700's stack and I believe all the others can cluster.
