Understanding the accumulation of data
The battle lines are drawn between 8 Gb Fibre Channel and 1 Gb or 10 Gb iSCSI and NFS. This is the baseline for my Interop debate. I am not arguing about the future of SAN, or even iSCSI versus NFS. Rather, I am arguing that most businesses would be best served by implementing an iSCSI SAN rather than purchasing Fibre Channel today.
iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade. FCoE, on the other hand, is likely to take over in high-end enterprise shops. It is relentlessly promoted by major vendors, and it seems that they will force the upgrade eventually.
It’s never been a better time to be in the market for enterprise storage products, with many excellent options available at affordable prices. But the market can be confusing for the uninitiated, with a variety of network options and capabilities. Even those of us “in the know” about enterprise storage are sometimes surprised by the offerings and companies in this space! So when Jerome Wendt from DCIG approached me to collect data for a market overview and buyer’s guide, I was excited. It was my big chance to really get to know these products!
Just how fast is 10 gigabits per second anyway? To help out, I’ve prepared another napkin-tastic infographic!
In Philosophiæ Naturalis, Sir Isaac Newton defined inertia. Although he was referring to physical objects, the power of inertia affects companies, markets, and relationships in the same manner. Humans are creatures of habit, and change is challenging. When faced with a choice of continuing along the same road or branching off in a new direction, most will choose familiarity.
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 fine over twisted pair, and short interconnect distances would reduce power draw to reasonable levels. 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, 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 industry the chance to reevaluate the current state of the art and has exposed real weaknesses in the Ethernet-centric future of the data center.
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.
“Maximizing Hyper-V iSCSI Performance with Microsoft and Intel” might sound like another “blah blah” marketing piece, but a little birdy tells me that this webcast will drop a bombshell about iSCSI performance.
I was thrilled to see the announcement by Blackmagic Design of two Thunderbolt versions of their respected Intensity video input/output box. But which is the better choice, the Intensity Shuttle or Intensity Extreme?
As a parent, especially a techie one, you never know when a teachable moment is going to appear. Last night, I mentioned that I was testing a new Ruckus access point and enthused about how fast it was. My 12-year-old asked, “why is it so fast?” This led to a wonderful discussion about radio waves, congestion and propagation, and spectrum licensing. Yeah, I’m that kind of dad.
Twitter is here to stay, and has become a potent communication tool in many industries. I recently received a request for advice on how better to use Twitter, and thought I would share some of the lessons I’ve learned over the years as an avid IT industry tweeter.
Make no mistake, the Das Keyboard Model S for Mac is a whole class better than the plastic junk most people use, and the snappy Cherry MX blue key switches are more rewarding than any scissor or membrane keyboard out there, but this is no IBM Model M, so buckling spring fans should look elsewhere.
EMC VFCache (née Project Lightning) is a fairly simple offering: A server-based PCIe flash card that acts as a read cache with no integration with storage arrays or hypervisors. But EMC’s entrance into the host-based flash storage market is a powerful demonstration of the wave of disruption caused by flash-based storage and high-performance computing.
The new Nimbus Data E-Class comes just at the right moment, with 500 TB of capacity, a fully redundant “dual active” controller architecture, massive performance (even InfiniBand), and complete feature set (once VAAI is released).
This week, two blog readers let me know what Google Chrome was warning them of malware on my blog. I dived in and discovered that, indeed, a nasty, obfuscated JavaScript attack had made its way into my site. Although I was disappointed by the lack of clarity about how to fix it, I believe I was able to remove it last night.
Although Clear clearly wants buyers to sign up for monthly service, they also have “secret” on-demand 2-hour, daily, and weekly plans. Here’s how to get online cheap!
HP stumbled mightily in 2011, and it had nothing to do with product or people. Even sales remained strong, though the PC business is changing. HP’s mighty stumble was a crisis of confidence due to a chain of shenanigans at the very top. This culminated with the short reign of Léo Apotheker, leaving HP to reassure the market of its strategy.
For a massive IT company, Dell sure doesn’t get the kind of respect given their competitors. Time and again, I’ll hear the sneers about Dell being little more than a “box shifter” who doesn’t “get” real enterprise IT needs. After a series of acquisitions in storage and networking, Dell is trying to stake a claim as a serious competitor to HP, IBM, Oracle, and the like. But why should anyone take Dell seriously, especially in enterprise storage?
