I would welcome both the advancement of the ARM family into the server market and the open standards as well. I can't help but think that competition is good and will provide the end user with a better more cost effective systems solution. I wonder how quickly the 64 bit ARM offerings can come out and what initial impact to cost/performance they will have?

Applied Micro will probably have the first ones out, either by the end of this year, or early next year. http://www.apm.com/products/x-gene

Good questions. The timing is clear. Applied expects to sample widely late this year and everybody (6+ companies) will have something shipping or sampling in 2014. Impact is less clear. This is a relatively small volume market where Intel has had $100+ ASPs that will likely now be closer to $20. Can you hear the gears grinding?

The big news I didn't know about until today was Intel has 100G silicon photonics in engineering samples for inside and outside the rack. A new, hot PHY is coming. Stay tuned for details

I think many underestimate the impact that silicon photonics could have. Silicon photonics will eventually allow for optical chip-to-chip data transfers that will drastically reduce energy consumption.

Silicon photonics could reshape the rack server, the components in it and even the data center. See http://www.eetimes.com/electronics-news/4405142/Slideshow--Facebook-shows-Intel-100GE--ARM-servers

Lets see how ARM fights up to big wigs of server world,which require high Performance and reliability. ARM is Stepping into world HP,Oracle & Big Blue, it should be fun.

ARM is not doing much by themselves, other than proving some "good enough" stock chips. It's all the other companies who are using ARM that you should be looking at, and some of them even have their own custom ARM cores. Also HP is already using ARM servers, and they will probably expand on it.

ARM would appear to have a limited appeal for servers in the data center but for the fact it is an energy-sipping technology. Once 64-bit ARM chips are available, we'll see. Charlie Babcock, editor at large, InformationWeek

Rumor has it China's Baidu is planning a 32-bit ARM server. Anyone know anything about it?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
