Symantec’s Thin API: The Plot Thickens

October 24, 2008 By Stephen 5 Comments

Last week, I lauded Symantec for introducing an API in Storage Foundation which will interact with the thin storage capabilities of supported arrays. Since then, I’ve learned more about this capability, and I am writing this update to share that knowledge. As I noted last week, the press release was a bit hard to follow and [...]

What is VMware VDC-OS vStorage?

September 19, 2008 By Stephen 2 Comments

Hopefully vCloud, vClient, and VDC-OS are a little more solid (not to mention closer) than the Three Pillars of Creation in the Eagle Nebula

VMware packed a lot into their 2008 VMworld conference, including an outline of their “three pillars” strategy, focused on vClient, vCloud, and something they are calling the Virtual Datacenter Operating System. While it is debatable if this last item really is an operating system, it’s certainly a major strategic change in messaging. VDC-OS is divided [...]

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?

Teaching Science with Wi-Fi (Thanks, Ruckus and MetaGeek!)

February 10, 2012

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.

Review: Das Keyboard Model S for Mac (and Why I’m Sending It Back)

February 8, 2012

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 (aka “Project Lightning”) Is One Small Step, But an Important One

February 6, 2012

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.

Nimbus E-Class: The First Big, Redundant, All-Flash Enterprise Array

January 31, 2012

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).

How My Blog Became Infected With MW:JS:150 Malware (And How I Fixed It)

January 26, 2012

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.

Cheap, No-Contract 4G Data: Clear’s Undocumented Daily- and Weekly-Pass Plans

January 23, 2012

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’s Mighty Stumble

January 19, 2012

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.

Why Should Anyone Take Dell Seriously in Enterprise Storage?

January 16, 2012

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?
