Storage-Centric vs. Network-Centric SAN Architecturesbunch of disks) alike. Consequently, even medium-sized SANs withvarying server requirements and classes of storage are better servedby a more hierarchical core-edge SAN design.Mesh SAN TopologiesIn conventional local area networks (LANs) and wide area networks(WANs), the network is composed of multiple switches and routerswired in a mesh topology. With multiple links connecting groups ofswitches and routers and routing protocols to determine optimumpaths through the network, the network can withstand an outage of anindividual link or switch and still deliver data from source to destination.This network-centric approach assumes that all connected enddevices are peers and that the role of the network is simply to provideany-to-any connectivity between peer devices.Figure 3.
