What Is a Blade Server?

In the server space, one of the biggest shifts was the form factor of the servers: From tower to rack-mount to blades. But what makes a blade server anyway? Let’s consider this for a moment, as we watch another shift in progress.

“Our Storage Array Is Compatible with VMware…” Says Who?

I talk to dozens of companies every week, and every one says the same thing: “Our product is compatible with VMware!” But not everyone’s definition of “compatible” is the same, and some are not compatible with the requirements of production data centers. Therefore, I present to you my spectrum of compatibility for VMware.

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

HP’s mighty stumble was a crisis of confidence due to a chain of shenanigans at the very top.

Why Should Anyone Take Dell Seriously in Enterprise Storage?

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.
