For IBM System x and BladeCenter, energy efficiency is not just a talking point.


IBM engineers have spent decades designing and building the most innovative, energy efficient servers in the market. IBM new generation x86 servers include the three most energy efficient x86 servers in the market, striking proof of the value of this effort – value that you can bring to your bottom line.
The most energy efficient x86 server: the iDataPlex dx360 M2 1
In a head-to-head match up of total cost of ownership, the IBM iDataPlex dx360 M2 will cost you 37% less than HP’s DL360 G5 server. It starts with extraordinary energy efficiency – industry leading, in fact. The value continues with lower hardware, software and management costs.
- The dx360 M2 offers 30% better performance per watt of energy used than HP’s DL360 G6 server
- The dx360 M2 has 26% better efficiency under heavy load for Web serving and search applications than the HP DL360 G6
- The dx360 M2 utilizes 60% less floor space than competitive servers
- It takes 102 HP DL360 G6 servers to get the same performance as 84 iDataPlex dx360 M2 servers
The most energy efficient 2-socket 1U and 2U servers: the System x3550 M2 and the System x3650 M2 1
In a head-to-head match up of new 2-socket 1U Intel® Xeon servers, the IBM System x3550 M2 delivers 5% better performance per watt than the Dell PowerEdge R610 and 22% better performance per watt than the HP DL360 G6. For 2-socket 2U Intel® Xeon servers, the IBM System x3650 M2 delivers 6% better performance per watt than the Dell PowerEdge R710 and 9% better performance per watt than the HP DL380 G6.
IBM delivers leadership results for 2-socket x86 rack servers across a range of industry benchmarks.
- IBM beats HP's published results in performance per watt, Java and SAP benchmarks. 3
- IBM beats Dell's published results in performance per watt, Java, SAP and transaction processing benchmarks, offering a strong virtualization option against competitive rack offerings. 3
- IBM can reduce your energy costs over $100 per server per year. 2
- IBM can help you use up to 25% less power when fully utilized, up to 60% reduction when idle vs. the current generation of servers while delivering over 60% higher performance. 4
