Connectivity – external and internal – continues to grow.  Aside from Cisco-Kerr black holes and the random Data Center wormhole, are we reaching a speed limit?  How does this impact multi-locational compute clusters?

“Notwithstanding an aggressive first strike by Extreme Networks, switching vendors are largely mum on when and in what configurations they will ship 40G Ethernet products.

Extreme announced and demonstrated four-port 40G Ethernet modules for its Summit X650 stackable edge and BlackDiamond modular switches at the Interop conference here this week. Extreme is pricing the modules aggressively: $1,000 per port, which is only $85 more than the average selling price of a 10G Ethernet port, according to Dell'Oro (DELL) Group.”
