I am not sure how the power consumption comparisons were done that put HP's switches at a lopsided advantage over Cisco's. For a given type of port that follows EEE's LPI (low power idle) mode implementation, I can not see such a big disparity. At a high level, the architecture involving LPI client requires a new service interface through a reconciliation sublayer. Therefore, any implementation of EEE ideally will see similar energy savings. Once the link is woken up, the differences in power consumption can come from the choice of PHY' used by a vendor. Most FCoE PHY's (Cortina, Broadcom, etc) have similar power consumption numbers so it is very unlikely to see such big differences between HP & Cisco gears. 10G Base-T is another matter! MP Divakar

HP is doing lot of investments in Ethernet products. But are these chips are commercially available for other OEM’s or only used in the HP products. I think Cisco definitely might be coming up with something to actually compete with the HP switches.

The result in power saving is due to Ethernet 802.3az or due to the new AISC? May be I think this is due the combined effect of both the things hardware as well software. As the article sys there is a huge difference between HP and Cisco switches that does not look like a fair comparison.

This is quite good but the blades marginalise this saving. Maybe if HP sticks these in each of their new servers a large farm will certainly benefit. This would become be default anyways in a short time and others will be there too. It's little steps like this which goes in making a big difference.

Cisco is keeping its software separate from its hardware: Catalyst 3750-X Series Product Activation Keys 3750-X IP Base to IP Services Upgrade 3750-X LAN Base to IP Services Upgrade Sincerely, Brad Reese

Hi, From a TCO perspecitive, HP has been leading the charter for a while now in terms of providing significant savings against Cisco and other vendors. As you can see from this independent third party report, the new EEE switches offer up to 55.3% TCO savings against comparable Cisco solutions. So with these products, customers not only realize reduced power consumption but also save on TCO Video Report: http://www.youtube.com/watch?v=QcuE_dxV_2c PDF report: http://h17007.www1.hp.com/docs/reports/tolly/tolly_12810.pdf Cheers, Sreeram Krishnamachari

Energy efficiency is quite attractive feature especially in ethernet switches. I guess its just the satrting it will soon catch the market. Afterall who doesnt want to be more energy efficient. I was wondering are there any drawbacks, I am sure cost wont be really different from other competitors.

It all depends on the cost. It it price-competitive, I will go for it. My concern though is Cisco as HP has become a fierce competitor. It is just beginning.

What are your plans for adopting EEE?
