Virtual Wiki. ToR switch placement â not at the top! You may know about ToR, top-of-rack (for) switches. Itâs the practice of placing a physical switch within each rack, so that the network switching for the rack is close to the servers or devices that need to connect to it. The ToR switches will allow servers to communicate with each other directly, and therefore reduces overall traffic on core switching.
You need a UPS, which is typically 2U or 4U and your ToR switch takes up 1U or 2U. So, the maximum amount of servers you can have in a rack would realistically be 40. Most data centers have much less than this â around 30. In order to connect all of these servers to a ToR switch, you would need a 48-port switch.
