It seems like manufacturers are shifting their focus to create chips that are increasingly energy efficient. Not only are they looking for chips that boost the performance of the server, they also make sure that as little energy is used as possible. Not only for chips, but for servers themselves, it seems the green revolution is taking place. Paul - http://www.connetu.com/

It seems to be the case that server manufacturers are spoilt for choice nowadays. I was shopping for a dedicated server for my office and was introduced by the salesman to ARM and Intel based servers, and to date I have no idea which is better. Paul - http://www.connetu.com/

Looks like a really nice chip for an office router and network attached storage server. For Web front-ending, 32-bit software is fine and even though the clock rate is less than x86 devices, memory is still a bottleneck. Four cores of anything will be fighting for memory, which will make it interesting to see some system benchmarks rather than trivial 100 line programs that fit in cache. The LAMP stack has been ported to ARM which leaves pricing to determine adoption. Low power will help, but a couple of SATA drives will take more power than most cores. Remember Cobolt before Sun swallowed them up? This looks exciting.

Is there a significant market for 32-bit ARM server processors? How successful do you think Calxeda or Marvell (Armada XP) will be in getting sockets?

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.
