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.
Visitors to the Fibre Channel Industry Association (FCIA) booth at Storage Networking World in Orlando were greeted by a strange symbol, but what is the symbol exactly? I was amused to get some puzzled looks (and no correct answers) when I polled a number of industry insiders.
Networking may be straightforward, but the world of networking terminology is not. I’ve been steeped in the strange lingo of Ethernet for many years, but I still get confused by some of the terms. What’s the difference between 1000BASE-CX, 1000BASE-SX, and 1000BASE-T? In this post, I’m going to tackle this Ethernet network naming convention.
The storage and networking industry is pushing for high-end Fibre Channel over Ethernet (FCoE), and its dominance of FCoE seems almost certain to many industry watchers. But where is Microsoft when it comes to FCoE? Put simply, Microsoft does not seem to be participating in FCoE development, either on the initiator or target side.
What’s the difference between naughty and nice when it comes to IT companies? Microsoft and EMC would definitely not have made the nice list over the last decade, but things are changing. With their competition taking dents in the ongoing battles, Microsoft and EMC just don’t look so bad anymore.
I am spending a few weeks examining the truths and fictions that bind our industry together. Let’s start with one of my favorite old canards: That enterprise storage must be overpriced because bare disk drives are so cheap.
I have seen this straw man argument set up by so many throughout my career that it has [...]
I usually welcome discussion (and even argument) about the things I know best: There is always more to learn, and the best insights come through engaging those who disagree with us. But some ideas have been argued so well for so long that they deserve enshrinement. For example, although non-scientists like to argue about evolution [...]
Championing “open” and calling for standards has become the first stalling action by late-movers in technology spaces. They see opportunity passing by and try to hold back progress and FUD the market by yelling about proprietary solutions, vendor lock-in, and a lack of standards. Many well-intentioned IT folks follow along: After all, who doesn’t want openness, standardization, and interoperability?
Western Digital announced this morning the world’s first “1 TB mobile hard drive!” But although the news is great for storage-hungry folks looking for a portable external drive, it doesn’t quite mark a sea change in the storage industry since this drive cannot be used in (most) laptops.
Not For Laptops
As we’ve discussed before, modern laptops [...]
Hiding in the shadow of the huge VMware vSphere 4 announcement was a very interesting introduction by EMC: PowerPath/VE. As I mentioned in my post on storage changes in vSphere 4, PowerPath/VE plugs into the new pluggable storage architecture (PSA) found in vSphere 4 versions of ESX and takes over the decision-making and heavy-lifting tasks related to communicating with storage systems.D
