Throughput numbers are shown in 10^6 bits per second, or Mbps. As the chart shows, one NIC transmits well over 947 Mbps of user data across the Gigabit Ethernet link. Two NICs scale at 2x the performance of a single NIC to transmit 1895.99 Mbps. Four NICs scale at 4x the performance of a single NIC, transmitting a total of more than 3792 Mbps of user data. On the receive side, one NIC receives up to 948.13 Mbps of user data. Two NICs scale to approximately 2x the performance of a single NIC, receiving 1853.09 Mbps. Four NICs scale at approximately 4x the performance of a single NIC, receiving up to 3325.21 Mbps. The chart demonstrates outstanding performance, with linear scaling on transmit and receive for up to four cards. Thus, the rp7410 supports up to four Gigabit Ethernet adapters at full unidirectional link rate. Additional NICs can be added to provide greater connectivity, up to a total of 15 Gigabit Ethernet cards for the system. For example, two more NICs add an additional 500 Mbps of bi-directional throughput, yielding an aggregate bandwidth across the six NICs of 4413.41 Mbps of bi-directional data. Page 5

The above chart shows the throughput performance of 1, 2, and 4 Gigabit Ethernet cards in an 8-way
rp7410.
Throughput numbers are shown in 10^6 bits per second, or Mbps.
As the chart shows, one NIC transmits well over 947 Mbps of user data across the Gigabit Ethernet link.
Two NICs scale at 2x the performance of a single NIC to transmit 1895.99 Mbps.
Four NICs scale at 4x
the performance of a single NIC, transmitting a total of more than 3792 Mbps of user data.
On the receive side, one NIC receives up to 948.13 Mbps of user data.
Two NICs scale to approximately
2x the performance of a single NIC, receiving 1853.09 Mbps.
Four NICs scale at approximately 4x the
performance of a single NIC, receiving up to 3325.21 Mbps.
The chart demonstrates outstanding performance, with linear scaling on transmit and receive for up to
four cards.
Thus, the rp7410 supports up to four Gigabit Ethernet adapters at full unidirectional link rate.
Additional NICs can be added to provide greater connectivity, up to a total of 15 Gigabit Ethernet cards
for the system.
For example, two more NICs add an additional 500 Mbps of bi-directional throughput,
yielding an aggregate bandwidth across the six NICs of 4413.41 Mbps of bi-directional data.
