Networking, Servers and pinging. looking for ideas

So I am looking for some ideas why a certain setup is not working. This is a school lab environment that i am working to help set up and me and the professor are both stumped on what is wrong. Any working professionals or other students want to take a stab at this?

We have a blade chassis that has a 16 port giga-bit switch card installed and have 16 blades plugged into the chassis. I have 2 blades one running server windows 2012r2 and 2008r2. They both have static IP setup the first one has 192.168.103.10 and the other has 192.168.104.10.

The switch on the back of the chassis has port 1 to blade 1 port 2 to blade 2 down the line. This is connected to a level 3 switch (routing capable) and the ports on the switch are pre-assigned address. port 1 is 192.168.101.1, port 2192.168.102.1, ect (3rd octet is what changes).

The subnet is 255.255.255.0 for all devices.

So..... blade 3 is connected to to switch port 192.168.103.1 with a server IP of 192.168.103.10 blade 4 is connected to to switch port 192.168.104.1 with a server IP of 192.168.104.10

Each server can ping its own gateway (the switch port) and also each server can ping the gateway of the other server.

The problem is that the servers are not able to ping each other. I need to get server communication for the ability to control a VM environment.

Thoughts? Ideas?Solutions?

you need to go and do a traceroute between them and create a static route between them since ip 192.168.103.1/24 doesn't know anything about 192.168.104.1/24 so you need to present each other on the table route so they can know how to route the traffic from one network to the other one
