The Impact Of VMware Storage Integration

admin — Tue, 13 Jul 2010 14:19:41 +0000

Today is the day that VMware announces the availability of 4.1, and a key set of storage integration APIs (VAAI) that provide all sorts of cool speed-ups between server and storage. EMC's announcement of day-one support is here . Chad Sakac (our legendary Virtual Geek ) does a great job of explaining what they are, how to use them, and what they can do for you. If your passion is hands-on tech, please head on over there. However, if you're more like me, and are always curious about what things might mean in a broader sense, this post might be more to your liking …

How Will You Manage Storage?

admin — Mon, 12 Jul 2010 17:02:12 +0000

As the IT industry rapidly transitions and matures, all sorts of traditional topics are now up for a fresh round of discussion. One of these topics that I'm getting frequently dragged into is storage management — what will it look like going forward?

Cloud Is In The Eye Of The Beholder

admin — Fri, 25 Jun 2010 20:03:45 +0000

Lots of cloud chatter this week. A couple of good industry events. An interesting new startup offering a cloud operating system for private clouds. Even the ever-outspoken Werner dissing private clouds as "false clouds". A lively debate, to be sure! Time for me to offer up another attempted level-set in this discussion. It's easy to become lost in the details, and more difficult to see what's really happening here — or, at least, what I think is happening. Disruption Is In The Air Clouds disrupt three aspects of technology: how it's built, how it's operated and how it's consumed. Other than that, it's business as usual There's excitement in the air, but also certain degree of fear. The deck chairs are starting to get re-arranged in the IT vendor world. Hot winds of change are blowing through enterprise IT organizations. And vast piles of capital are flowing into the new intermediaries — the service providers. As all of this happens, I'd encourage everyone to remember the golden rule.

Reconsidering the LUN

admin — Mon, 07 Jun 2010 15:20:54 +0000

I wrote previously about my current challenges involved with unlearning just about everything I've ever learned about storage. One fun exercise is to take terms and concepts we've been using for many years, and look at how their definition has evolved to a point that they're somewhat unrecognizable as compared to where they started. And today, I'm going to have some fun with LUNs … LUN — The Fundamental Unit Of Storage Allocation If you'd like a clinical treatment, I'd refer you to the Wikipedia entry here .

Unlearning Storage

admin — Tue, 01 Jun 2010 14:49:45 +0000

In a recent interview with Dave Vellante of Wikibon fame, I offered up the view that — given the rapid rate of change in storage technology — I've had to revisit just about each and every fundamental assumption I've ever had about storage. An excellent example of this "unlearning storage" was buried in an Atmos announcement from EMC World. In particular, Atmos storage now runs nicely in a VM. Not just for eval, for production

Why I Never Embraced Facebook

admin — Sat, 15 May 2010 17:03:46 +0000

A while back, it was part of my job to understand all the different social platforms as part of an effort to make EMC proficient at social media. If it was out there, I investigated it. Blogs. Forums. Second Life. Twitter. Yammer. Ning. You name it, I checked it out. Some of these platforms made sense to me, others didn't. Some I embraced (e.g communities, blogging, Twitter), others I largely stayed away from. And Facebook was one of those that simply raised hairs on the back of my neck.

Redefining RAID

admin — Fri, 14 May 2010 20:45:40 +0000

If there's one topic that's been discussed to death in the storage industry, it's RAID — a redundant array of independent disks. No, this post isn't really about this version of RAID or that version of RAID, it's just a suggestion that — before too long — we might use this acronym to refer to a very different (yet intriguingly related) concept. To Begin With If all this storage stuff is new to you, don't fret. The idea is simple — use multiple disk drives that can appear as one: bigger, faster and more reliable. In the storage world, the advent of RAID fundamentally changed the industry in a substantial manner. Interesting note: if you'd like to see an interview from the DG engineers who built the first commercial RAID array (the CLARiiON), check this out. All of them are still at EMC During the video, the thought comes out that the advance was driven by two things: growth in the power of CPUs, and new IP — in this case, the foundational Berkeley paper on RAID concepts

Mid-tier Storage Accelerates

admin — Tue, 11 May 2010 15:39:57 +0000

The bread – and-butter of the storage industry is mid-tier storage — pragmatic dual-controller designs that do it all for a big piece of the IT landscape. It goes by many names: mid-tier, modular, unified, etc. Dual-controller designs provide a nice balance between performance, capacity and availability for so many storage requirements. Whether it's a modest IT shop, a modest project in a larger shop, or a whole fleet of them in a really big shop – these dual-controller storage designs continue to be a staple of the industry. It's also a hotly contested portion of the market — just about everyone has offerings in this space: EMC, NetApp, HDS, HP, IBM, etc. etc. In a notoriously competitive segment, this is where it can get most competitive. Fights break out over minor things like the definition of "unified", for example.

Backup Isn’t Dead, It’s Just Evolving

admin — Tue, 27 Apr 2010 14:44:22 +0000

The blogosphere can be a crowded, noisy place — especially when it comes to storage-related topics. Sometimes I think people say outrageous things intentionally. I suppose if your goal is to draw attention to yourself, the tactic might make sense. But if your goal is to help others, saying outrageous things just adds to the noise and confusion — especially around a relatively important topics such as backup — and really doesn't help anyone

Virtual Storage, Global Federation and Distributed Cache Coherence Follow-Up

admin — Thu, 11 Mar 2010 18:50:59 +0000

Lots to talk about as a follow-on from today's discussion around virtual storage, global federation and the underlying distributed cache coherence technology that makes all this wonderful juju possible. Most of the focus was on the specific capabilities around global storage federation, and the underlying distributed cache coherence technology that makes all of this useful and interesting
