The Joys of Ethernet

What would someone who invented ATA-over-Ethernet say? On top of that, I called my products EtherDrive SAN. Kind of get the picture? I love Ethernet. This is a modern photo of some crazy person (not me) playing with 10Base5. That’s 10 as in 10 Mb and 5 as in 500 meters, or how long a yellow snake you could hide above the acoustic tiles and still work. And ... Read more→

They are a part of our daily lives. Using VMware or Hyper-V under windows, we run dozen, hundreds, and for large shops, even thousands of them. What are they? Virtual Machines. Flocks, swarms, should I say it, clouds of machines that are the mere software imagined hardware. ... Read more→
