## 2.2.4 Full mesh topology 

In a full mesh topology, all switches are interconnected to all other switches on the same fabric. So the server and storage placement is not a concern after the number of hops is no more than one hop. Figure 2-5 shows a full mesh topology.

## 2.2.5 IBM FlashSystem as a SAN bridge 

IBM FlashSystem now has a maximum of 24 ports. In addition to the increased throughput capacity, this number of ports enables new possibilities and allows different kinds of topologies and migration scenarios. 

One of these topologies is the use of a FlashSystem as a bridge between two isolated SANs. This configuration is useful for storage migration or sharing resources between SAN environments without merging them. Another use is if you have devices with different SAN requirements in your installation.
