FIGURE 14. MUlti Tier SAN Design across an Extended Link
Depicted in the next diagram is a 20 switch fabric, three tier, with 4 switches at the core. This fabric offers 2 hops from source to destina-
tions, with multiple equal cost paths between devices allowing for device failover without a performance lost due to added latency.
These links are via DWDM,
not shown in diagram.
DESIGN: 16 SWITCHES, TWO LOCATIONS; TOTAL PORTS= 212 USING 16 PORT SWITCHES
