Quick Question on VSAN vs XtremIO Architectures

This is just a really quick one…… I noticed that upgrading an existing VSAN to the newly announced VSAN 6.0 is a non-disruptive rolling upgrade. Fair enough, so it should be right? Well…… part of the upgrade requires what sounds like a fairly significant underlying on-disk layout change.  Basically, the upgrade to VSAN 6.0 updates… Read More »

Docker on Windows – Some Insight

So last week I had a cracking and informative conversation on Twitter about native Docker support on the next version of Windows Server. So I thought it only right to scribble down the good stuff here for anyone who didn’t get a chance to listen in and get involved. It all started when Stu Miniman… Read More »

Stop Hiding the Negatives!

I was asked to comment on Chad Sakac’s post about not trusting people who *go negative*.  Basically Chad is telling us not to trust anyone that says negative stuff about a technology.  Frankly I think that notion is dangerous and absurd! NOTE:  I’ve no beef with EMC, XtremIO here. I just think what Chad is… Read More »

A Container First Approach

And that’s all well and good.… Read More »

Nimble Storage – Heir to the Throne of the SME?

I’m seriously thinking the recent announcement that Nimble Storage will support Fibre Channel might herald the birth of a new major primary storage player. And I seriously mean a major player… right up there with EMC, NetApp, HDS, HP… How come? Isn’t the FC market flat? Well, may be. But it’s still a huge-old market.… Read More »

Sorry Nimble Storage – I Don’t Believe You!

So a few weeks ago I was at Nimble Storage HQ for a briefing with the Storage Field Day crew. Nice site, nice breakfast, and thanks for contributing towards my travel and hotel costs (that’s the disclaimer out of the way). The Claim! Anyway, as part of the presentation, Rod Bagg (VP of Customer Support)… Read More »

So in this weeks In Tech We Trust Podcast (listen via the controls below) we talked a bunch about Docker. And part way through the conversation Marc Farley suggested we back up a little and give a quick primer on Docker and Containers. Cracking idea. So we did that on the podcast, but I think… Read More »
