ATIS-weighted Power (W ATIS
) = 0.1*(Power draw @ 0% load) + 0.8*(Power draw @ 10% load) + 0.1*(Power draw @ 100% load), as defined in ATIS
standards ATIS-0600015.03.2009 and ATIS-0600015.2009
Note:
Test traffic consisted of an Internet Mix (iMIX) distribution of TCP packet sizes: 57% at 64-bytes, 7% at 570-bytes, 16% at 594-bytes and 20% at
1,518-bytes
Understand how HP Networking EVPG illustrates what “Green” means and how by enabling EEE, HP Networking has adopted
standards that enable simple plug and play power savings without the need for cumbersome management software or licenses.
