Understanding the accumulation of data
I’ve really jumped into recording podcasts, and am also an avid audio and video conference user. Wanting better sound, I upgraded my Logitech microphone to the highly-regarded Blue Microphones Snowball desktop USB microphone. Here are my initial thoughts.
Although it’s rare in the PC world, multipath I/O is not new in enterprise IT. I’ve been juggling paths to storage and networks as long as I’ve been a systems administrator, and that’s a bit longer than I care to admit. But the proliferation of technologies has made it difficult to understand path management. What’s the difference between “dual active” and “active/active”? Is “active/passive” really that bad?
Although subjected to Apple’s usual silent treatment before the big unveil, Apple has released waves of detail since. Yet, even as pre-orders are shipping, there are still many things we don’t know about the iPad. What surprises are in store?
Last week I posted the excellent news that the Robocopy in new versions of Microsoft Windows is multi-threaded and thus much (much!) faster. Then I tried to actually use it on a Windows Vista machine. Redmond, we have a problem. It turns out that only the “6.1″ versions of Microsoft Windows (Windows 7 and Windows Server 2008 R2) include multi-threaded robocopy.
Robocopy is the best tool to move data between NTFS filesystems but was never very quick. Windows Vista, Windows Server 2008, and later versions include a new version of Robocopy with performance tweaks including multi-threading that speed things up dramatically.
Ever since Microsoft and Intel declared that the combination of Windows and Nehalem could deliver over a million iSCSI IOPS, I’ve been curious about just how they did it. What black magic could push that many I/Os over a single Ethernet connection? And what was on the other end? Now Intel has revealed all in a whitepaper, and the results are surprising!
I’m pleased to be heading back to Interop this spring with two sessions on enterprise storage. Although significantly changed from the old “Networld + Interop” days, the event is enjoyable and technical, with many interesting sessions and speakers. And the New York show at least had plenty of end user attendees!
When Apple announced the iPad, I was puzzled that Microsoft Exchange email support was not listed. Happily, Apple updated the iPad site and Microsoft Exchange support is now included.
One of my favorite features of Apple’s Mac OS X is the clean and simple media players bundled within. But I often find myself wanting to watch a movie without my remote in hand, and was distressed to see that Apple implemented entirely different keyboard shortcuts for the transport controls in QuickTime 7, QuickTime X, and Front Row.
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?
Any time OS X corrects your spelling or (more likely) inserts appropriate accent marks, Dictate loses its mind and can no longer correctly enter some random letter. There are two ways to fix this problem (apart from just restarting Dictate all the time).
Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.
The difference between American and European mobile phone providers are vast, and the modern traveler is likely to run afoul if they are unprepared, running up a surprisingly large bill! Here’s a rundown of my standard techniques to prepare my American mobile phone for travel abroad.
The CompactFlash Association announced a new media card format last month, and now Sony and Nikon have introduced the first media and digital cameras, respectively. But what exactly is an XQD memory card? Read on for the details.
What elements remain unresolved to make FCoE truly world-class? What should the vendors be prioritizing?
Although they are ridiculously inefficient, incandescent lightbulbs seem to have a huge number of fans. Despite the romance of the glowing filament, many governments are moving to ban the use of incandescent light bulbs in many applications. Here in the United States, the federal government intends to encourage the use of more efficient light bulbs but there is no outright ban.
