Performance and Recommended Use of AD222A, AD393A, and AD221A PCIe Combination 4-Gbit/s Fibre Channel and Gigabit Ethernet Cards

1 FC Port and 1 GbE Port Combined Traffic
Performance
Figure 10 shows the performance results when mixed traffic is run simultaneously through
one 4-Gb Fibre Channel port and one Gigabit Ethernet port on the AD222A or AD393A
or AD221A card.
The following highlights show the exceptional performance the AD222A achieved during
combination traffic testing:
• The first three blue bars show disk read traffic consistently achieved greater than 99%
of link rate on the rx6600 system. The active port achieved 405 MB/s or greater of
disk read throughput. This was while continuous, full standard-Ethernet-frame traffic
was occurring on the active 1000Base-T port.
• The middle three blue bars show disk write traffic achieved greater than 99% of link
rate on the rx6600 system. The active FC port achieved 405 MB/s disk write
throughput. This was while continuous, full standard-Ethernet-frame traffic was
occurring on the active 1000Base-T port.
• The last three blue bars show disk bi-directional traffic achieved greater than 99% of
link rate on the rx6600 system. The active FC port achieved 1640 MB/s disk
