TCP Chimney scales…
Higher is better
Lower is better
TOE L2
TOE L2
BW improvement TOE vs. L2
CPU Utilization reduction TOE vs. L2
2.5G/S offers more BW than non-TOE, at 1/6 of the CPU utilization
Microsoft’s SNP combined with BCM5708 provides 7.5 times better P/E
Performance Efficiency (P/E) is network throughput divided by CPU Utilization
At Gigabit and beyond, TCP Chimney is critical to free up cycles for the applications
