2–Planning Performance

Performance

The QLogic 9000 Series switch supports class 2 and class 3 Fibre Channel service at transmission rates of 1-, 2-, 4-, 8-, and 10-Gbps with a maximum frame size of 2148 bytes. A port adapts its transmission speed to match that of the device to which it is connected prior to login when the connected device powers up. Related performance characteristics include the following:

Distance

Bandwidth

Latency

Distance

Consider the physical distribution of devices and switches in the fabric. Choose transceivers that are compatible with the cable type, distance, Fibre Channel revision level, and the device host bus adapter. Refer to Appendix A for more information about cable types and transceivers.

Each SFP and X2 port is supported by a data buffer with a 16 credit capacity; that is, 16 maximum sized frames. For fibre optic cables, this enables full bandwidth over the following approximate distances:

26 kilometers at 1-Gbps (0.6 credits/Km)

13 kilometers at 2-Gbps (1.2 credits/Km)

6 kilometers at 4-Gbps (2.4 credits/km)

3 kilometers at 8-Gbps (4.8 credits/km)

2 kilometers at 10-Gbps (7.2 credits/km)

Longer distances can be spanned at full bandwidth on SFP ports and X2 ports by extending credits to G_Ports, F_Ports, and E_Ports using Enterprise Fabric Suite 2007. Each port can donate 15 credits to a pool from which a recipient port on the same I/O blade can borrow. The recipient port also loses a credit in the process. For example, you can configure a recipient port to borrow 15 credits from one donor port for a total of 30 credits (15+15=30).

Ports can borrow credits from other ports of like kind: SFP ports can borrow from SFP ports; X2 ports can borrow from X2. However, SFP ports cannot loan or borrow credits from X2 ports.
