This regular series features highlights from the week. It was another big one for me, with my Network Computing writing gig starting up, the announcement of my Storage for Server Virtualization seminar series, and the finalization of Tech Field Day for February. Things I wrote I kicked off my new Network Computing column with this one: Ethernet Has A Goldilocks Problem … [Read more...] about Back From the Pile: Interesting Links, January 14, 2011
In PhilosophiÃ¦ Naturalis, Sir Isaac Newton defined inertia as follows: The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to preserve its present state, whether it be of rest or of moving uniformly forward in a straight line. Although Newton was referring to physical objects, the power of inertia affects … [Read more...] about The Three Requirements To Overcome Inertia
As I considered the possibilities of the new Apple/Intel interconnect technology known as Light Peak, an odd parallel with 10 Gb Ethernet popped into my head. Much of the confusion around Light Peak revolves around connectors, power conduction, and backward-compatibility. Then, like the Grinch, I thought of something I hadn't before: Why use optical at all? 10 GBASE-T does just … [Read more...] about What If Light Peak Was Electrical Rather Than Optical?
The buzz about Fibre Channel over Token Ring has built rapidly over the last week. Industry experts like Greg Ferro, Denton Gentry, and Joe Onisick have weighed in (as have I), and the Packet Pushers Podcast featured the news in show 12, "Get on the Ring!" Some have called out FCoTR as a foolish hoax, but the FCoTR phenomenon is not foolish. Indeed, FCoTR gives everyone in the … [Read more...] about The FCoTR Phenomenon Exposes the Weaknesses in Ethernet
Unless you're "in the know", terms like "layer 2" can seem mysterious, making it all the more plausible when someone touts the benefits. It seems logical: "Bare-metal" communication must be better, faster, and cheaper than higher-level "everything over IP" approaches, right? But it's not quite that simple. This piece assumes you know something about the OSI model. Ivan … [Read more...] about The Lure of Layer 2
