I'm not really getting the appeal here. 45 wimply processors in 4U doesn't sound that great, given that anyone can get 16 conventional sockets in the same space - 512 cores, 64 ddr3/1600 channels! maybe the story here is the backplane, which hasn't seemed to get much coverage. does it provide something other than 2x Gb and power?

I believe HP has done something denser than VME (45 processor boards in a 4U) but probably without its mil/aero ruggedness (and cost) and more aligned with PC server standards such as PCI Express and Ethernet interconnects

But Rick, in general ip2design makes a good point, no? As for me, original or not, I'm happy to see a bold idea tried by an American company.

If the new HP servers offer a better value than what the ODMs can offer, then HP will get that business. I think these servers are pretty amazing

The cartridge form factor here is smaller than anything I have seen from the VME and CompactPCI folks that fits into a muscular server-targeted chassis. The VMEs of the world might sharpen their pencils over this one. Maybe they could break into the mainstream server world with another chassis.

Hello Haven't they re-invented the VME architecture ?

An all inclusive architecture. How could they lose? I wanted one until I got to the price tag. Should be a win for server farms.

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.
