In some cases, more than two switch cards are used to limit the backplane bandwidth reduction when any one switch card fails. 45 46 CHAPTER 3 Switch Fabric Technology Fat-tree topology The star topology can be scaled even further by adding higher port count FIC devices and increasing the number of switch chips in the system. One way to do this is to use the same switch device at both stages of the fabric. This can even be expanded to three or four stages although in many cases this is not practical.
These will be discussed in more detail in the last section in this chapter where we provide some examples of existing chip set architectures. SWITCH FABRIC TOPOLOGIES In the last section, we described several switch fabric architectures along with the limitations in implementing these architectures based on factors such as chip technology. For these basic network building blocks, a primary limitation is port count. Data center networks require tens of thousands of high-bandwidth endpoints while the best chip technology can provide around 100 high-bandwidth ports.
As frequencies are increased past a certain point, a single wire on the bus needs to be treated like a transmission line. But, by its nature, a bus has multiple stubs along the transmission line, causing signal degradation due to difficult termination and reflection issues. Because of this, shared busses must be limited in either maximum frequency or the number of devices connected to the bus. Increasing the width of the bus also provides design challenges. Increasing the bus width increases the pin count in both the device package and the board connectors and increases the board complexity, leading to higher system costs.
