	Before	After
Server	1P Intel® Core™2 Duo processor	4P Intel® Xeon® processor 7400
Cores	2	24
Game server processes	3 per CPU core	3 per VM; 4.5 per CPU core
VMs per box	N/A	36
Game server per box	6	108
Total users per box	72	1,296
CPU utilization	60-80%	75%
Power utilized per server	350 W	710 W
Consolidation ratio	18	1
Annual direct power cost	$731,000 per 1,000 servers	$83,000 per 56 servers

Power savings

Using the optimal number of virtual machines, which is 36, a simple calculation of direct power costs was done comparing the before (native) and after (virtualized).

Table 1 shows that with 36 virtual machines, with each virtual machine having three game servers and each game server supporting 12 players, we can see a consolidation ration of 18:1. This means we can consolidate 18 of ESL’s existing Intel® Core™2 Duo processor-based native servers onto one Intel Xeon proces- sor 7400 server by using virtualization in combination with VMDq and NetQueue technologies without impacting the gaming

latency and gaming experience. This translates to direct power- cost savings of $648,000 annually for every 1,000 Intel Core

2 Duo processor-based servers that will be converted. In these calculations we are taking into consideration that these game servers are running 24x7, 365 days per year, and we used the actual power rate ESL is paying (0.16 euros/kWh).

Other savings

The above savings are only direct power savings. We did not take into account other savings like cooling, datacenter space, network hardware, and manageability.
