Chapter 49 Configuring the SAN Extension Tuner License Prerequisites Send documentation comments to [email protected] Figure 49-2 N Port Tuning Configuration Physical Example Cisco MDS Switch Cisco MDS Switch FCIP link WAN or MAN FCIP link 120494 N port (Acts as initiator) N port (Acts as target) Figure 49-3 provides a sample logical setup in which the virtual N ports are created on ports that are not a part of the FCIP link for which the throughput and latency is measured. Figure 49-3 Logical Example of N Port Tuning for a FCIP Link Cisco MDS Switch GE 3/4 SAN Extension Tuner N ports Cisco MDS Switch GE 2/4 GE 3/3 FCIP link GE 2/3 120495 Data Pattern By default, an all-zero pattern is used as the pattern for data generated by the virtual N ports. You can optionally specify a file as the data pattern to be generated by selecting a data pattern file from one of three locations: the bootflash: directory, the volatile: directory, or the slot0: directory. This option is especially useful when testing compression over FCIP links. You can also use Canterbury corpus or artificial corpus files for benchmarking purposes. License Prerequisites To use the SET, you need to obtain the SAN_EXTN_OVER_IP license (see Chapter 10, "Obtaining and Installing Licenses").
