3 / 4 page  x4 x4 CPU CPU CPU CPU PEX 8617 x4 Memory x16 x16 x4 Chipset Endpoint PCIe Gen1 or PCIe Gen2 slots Endpoint Figure 3. Fan-in/out Usage Network Interface Cards The PEX 8617 can also be utilized in communications applications such as Network Interface Cards (NICs). NICs, like the one shown in Figure 4, can utilize the PEX 8617 for its fan-out capabilities. In the example below, the PEX 8617 is being used on a Dual-port 10- Gigabit Ethernet (GE) NIC card. The PEX 8617 utilizes a x8 link to connect to the host and two x4 downstream links to fan-out to the 10GE ports. The peer-to-peer communication feature of the PEX 8617 allows the endpoints to communicate with each other without any intervention or management by the host. 10 GE 10 GE MAC/PHY MAC/PHY x8 x4 x4 Dual-Port NIC PEX 8617 Figure 4. 10GE NIC Fan-Out Host Bus Adapters The PEX 8617 is well suited for Host Bus Adapter cards (HBAs) as well. Figure 5 shows a Quad-Port Fibre Channel HBAs utilizing the PEX 8617 to allow connectivity to two Fibre Channel (FC) controllers. The PEX 8617 uses a x8 link on the upstream port and two x4 downstream links to fan-out to the FC Controllers Each FC controller supports two FC ports. x8 x4 x4 Quad-Port FC HBA PEX 8617 FC FC FC Cont. FC FC FC Cont. Figure 5. Quad-Port Fibre-Channel HBA Failover Storage Systems The PEX 8617’s Dual Cast feature proves to be very useful in storage systems. In the example shown in Figure 6, the Dual Cast feature enables the PEX 8617 to copy data going to its two downstream ports to the backup system and vice versa (see yellow traffic patterns) in one transaction as opposed to having to execute two separate transactions to send data to the redundant chassis. By offloading the task of backing up data onto the secondary system, processor and system performance is enhanced. Non-Transparent (NT) ports are used to isolate the host domains of the backup system from the primary system. x4 CPU CPU CPU CPU Memory Chipset CPU CPU CPU CPU x4 PEX 8617 NT Memory Chipset 8 Disk Chassis PEX 8617 8 Disk Chassis FC Control FC Control FC Control FC Control NT PEX 8617 NT x4 x4 x4 x4 x4 x4 x4 x4 x4 Backup System PEX 8617 Figure 6.
