Finally...the icy days are over...Spring season seems to have arrived! At least the opening of the Swissmoto Expo in Zurich this past weekend seems to indicate that...the outside temperatures are still lagging behind, though.

Here's a summary of worthwhile news for the last couple news in the realm of storage, let's start with hard disk drives (HDDs) and potential ways to push the envelope for more capacity beyond perpendicular recording and GMR heads:
Shingled writes (picture below), HAMR (heat-assisted recording) and Helium-filled drives seem to be three proposed solutions to the challenge! While HAMR and Shingled writes would help to increase aerial density of HDD platters, the Helium used inside HDDs aims rather at allowing more platters per real-estate by lowering air-friction. Combining the two would yield the best results in terms of capacity increase but also obviously raise manufacturing costs.
Aerial density growth for HDDs has been down at the 20% level (per year) in the last couple years as you can read in this article by Hu Yoshida here, so to maintain capacity expansion, new technologies will be needed!
That same article also has some interesting trends regarding flash disk cost levels: expectations are that the per capacity costs of SSDs will reach SAS HDD levels in a 2019 time frame.

However, current products like the new 1.2TB SAS drive from WD are still based on traditional architectures!
The reasons why we desperately need more capacity are discussed in the most recent "Digital Universe" study: IDC predicts that "...the digital universe will reach 40 zettabytes (ZB) by 2020, an amount that exceeds previous forecasts by 5 ZBs, resulting in a 50-fold growth from the beginning of 2010". I personally would argue that the kind of snapshots taken all over the world by cell phone users are not an "act of creating information"... but obviously these pictures still use up storage space in various places. Find the complete report here!

And an outlook for the HDD market thru 2017 can be found here.


On the Wall Street side of our industry, the Q3 results of VMware generated some mixed echos: "VMware sees trouble ahead" was the title of an article in the financial press. But nevertheless, VMware continues to build out it's in-house storage ecosystem and announced the intent to acquire Virsto, the maker of "..the first VM-centric Storage Hypervisor".
Which closes the loop: Jon Toigo has his very own and distinct opinion about storage hypervisors (see graph above): "Then, when VMware engineers climbed on stage a year or so ago and said that they were going to add another microkernel they called a storage hypervisor to the clusterf#@k of microkernels that they fancy to be a OS, I couldn’t believe my ears. Imagine if each of the leading hypervisor vendors decide to do a storage virtualization microkernel too: that would suck."

It's January, it's cold and it's dark...time to book summer vacation - and review pictures from last year's summer vacation!
Although we got some snow in Zurich and we are reasonably well equipped to deal with snow and ice, the Canadians do it even better...very impressive parade of Snowplows!


Continuing with my December post on 2013 strategy statements and economic outlooks, here's the insights from HP's David Scott, Netapp's Jay Kid as well as a listing of the 15 most promising storage startups for the new year.
Even more interesting though is the list from a year ago (on that same link above) and the comparison between the two lists:
Some companies went from "most promising" to "unknown" (like Coraid) while others made it back onto that same list again (like Violin, ranked 2nd) or have been acquired (like XtremIO by EMC) or are well established brand names by now (like Dropbox).
You will notice that many of the listed companies are involved with some sort of SSD technology and solutions, the most exciting real product hitting the market these days is probably the Crucial 500, a 1 TB SSD drive for consumers which sells for under 600$!

Also in 2013, the industry expects the first SATA Express products, based on a 16 Gbps SATA standard which is under development. See the SATA-IO website here for details and this site here for additional information and resources.

Lastly, on the topic of the recent revival of tape, here's a great article by Jon Toigo: "The most important metric you're likely to confront in the next 10 to 20 years is the cost and availability of electricity."
Read here how he thinks SSD and Tape could be combined to address these challenges.
The Leibniz Supercomputer Center (LRZ) in Germany already uses this approach very successfully! Here's the related IBM Press Release.

Today I have couple various topics for you:
Year-end interviews with Tom Wultich (Oracle Tape Executive) and Chuck Hollis (EMC CTO) on how they see the storage market and their respective companies in 2013.


A couple future-related stories (beyond 2013!) and analysis coming from:
And lastly a very recent Computerworld report on SSD price trends: according to that report, SSDs recently  broke the magic 1$/GB price point and have dropped more than 20% since the beginning of 2012!
