Disk I/O Tuning
fabric topology permits dynamic interconnections between nodes
through ports connected to a fabric. This fabric is similar to a
switch or router and is often compared to a telephone system because
of its redundant rerouting capabilities. The fabric topology also
allows multiple connections simultaneously, unlike FC-AL which
results in a single circuit being established between only two ports
at any one particular time. Fabric and arbitrated loop topologies
may be combined in one system to provide a wide variety of services
and performance levels to the nodes.
Point-to-Point topologies are used only to connect two ports without
any routing capabilities.
