Storage Nation

IOPS Per RAID Group, ordered by most to least I took part in a podcast last night that discussed the XIV platform.  One of the “key features” of XIV is the wide striping of data across all spindles.  It’s a concept we’re seeing more and more in contemporary storage hardware architectures and one that’s being shoe-horned into older storage arrays too.  Have you ever wondered what the point is?  Take a look at the following graphic.  It shows the number of write operations per RAID group, ordered by the busiest RAID group to the least active.  It’s real data from a real system.  What you see is the Long Tail effect, where a small number of RAID groups are doing most of the I/O.  In this example, 80% of the workload is performed by 50% of the RAID groups; only 3 RAID groups account for 20% of the workload.

The news is here . It's gratifying to see our international business growing

I finally managed to attend a London CloudCamp last Thursday, which conveniently co-incided with a #storagebeers evening.  For two hours of listening to the collective wisdom of the presenters and the “unpanel” we were offered free beer and food

Okay, I knuckled under to pressure.  First, Leigh Grace tried to sell me on Twittering (which led me to use it as a way to notify everyone about new posts here), then I got a call from Rose Ross over in the UK who relayed to me that folks were sending me messages — tweets

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

ESJ.com is running another of our C-4 Project video segments, this time with CEO and Chairman of FalconStor, ReiJane Huai.  Check it out. Mr. Huai reflected on his role in bringing tape backup to the distributed world, then offered commentary on several topics of interest including the formation of mini-me mainframes (“if you are going to

For those of us in the IT business, we occasionally encounter a fundamental new enabling technology that forces us to reconsider some of our long-held notions around the way things work. I'd put server and desktop virtualization into that category, as well as the ubiquitous web.  If you're a storage person, flash has that potential as well.  If backup is your thing, the combination of dedupe and low-cost disks has changed how you think about things. In this post, I'd like to start to introduce a technology concept that — yes — has the potential to change a great deal of how we think about IT at scale.  And, yes, this is going to be a long post … Context Today, Pat Gelsinger did an important event with industry analysts.  You can see his materials and webcast here .  In addition, I wanted to offer up my views on this topic as well.  I'll be using his slide deck as a reference point

The tickler I received in email this AM filled me with interest in what Mr. Foskett, lately of Nirvanix, was going to write about this question in his multi-part blog.  My fingers tingled with expectation as I keyed in the URL for his postings

Over the last week there have been a few stories catching my eye.  Here’s a brief paragraph on them. SGI Acquires COPAN Systems In fact to be more precise, SGI have acquired some of the assets of COPAN and left the liabilities behind for a mere $2 million in cash ( press release ).  The demise of COPAN raises two potential questions; is spin-down a dead technology or were COPAN in a market that wasn’t able to understand their technology

No, this is not another shameless pitch to attend yet-another-vendor show.
