The Hanukkah Armadillo and predictions for 2010.

18/12/2009

PL Junior is three years old and a bit, and I thought I’d share an interesting conversation from Friday last week, which was the first night of Hanukkah, whilst I was driving PL Junior to school.

‘Daddy, when will it be dark?’

‘Not until this evening, I’m afraid.  Why do you ask?’

‘Is tonight Hanukkah?’

‘Yes, it is …as soon as the sun goes down.’

‘When it gets dark we light the candles?’

‘Yes, are you excited?’

‘Um hmmm!  After the candles the Hanukkah Armadillo will come and sing me a lullaby.  And bring me presents!’

I start to laugh.  PL Junior isn’t.  He’s deadly serious.

‘Erm, sure. I suppose.‘  Not good to hurt a three year old’s feelings.  Best play along.

‘What else does the Hanukkah Armadillo do?’

‘He has flying powers, just like rocket!  And big jet!  And he comes down with presents each night of Hanukkah!  But he doesn’t like biscuits.  Only water and cucumbers.’

I dropped off PL Junior at school and then phoned Mrs. PL where, after we got done laughing, she tells me that she was channel hopping recently when she happened upon the Friends episode with the Holiday Armadillo.  It being one of her [and my] favourites, she watched and laughed.

PL Junior didn’t.  My father lives in Texas.  PL Junior thought it was real.  So, being a great mum, Mrs. PL decided to just go with it.  And thus was born the legend of the Hanukkah Armadillo in Casa PL.

My father just sent me an email offering to send a stuffed armadillo to place next to our menorah.

Thanks dad.

What’s this got to do with Data Storage & Protection?

One of the many things that I love about living in the UK generally and London specifically is the amazing diversity and breadth of opinion.

I don’t know if there is such as thing as a Universal Truth other than to say that everyone I know and work with would describe family as being paramount.  It doesn’t really matter much if you celebrate Christmas, Hanukkah, Diwali, Eid, Kwanzaa, Christmaskah, or Festivus …or none of these …you tend to do what you do because it makes you and your family happy.  And, frankly, how you observe or celebrate will often vary from family to family …who’s to say if there’s a ‘right’ way or ‘wrong’ way to do it?

Although I must say, there is a lot of merit in the Airing of Grievances around the Festivus pole.  But I digress.

As I’ve said before, I have a religion and it ain’t storage.  I’m not aware of any ‘one size fits all’ solution, but we have developed an equation and methodology which gives us as fair and equitable a way as I know for selecting and recommending solutions.  Just as families celebrate holidays in different ways so too do customers select and implement technologies.

That said, my predictions for 2010:

1.  The emergence of the virtualised datacentre.

What do you get if you add optimised storage, deduplication, storage compression, converged networks, virtualised servers, virtualised applications, integrated backup to disk/replication/tape storage, automation for the whole lot …I’m probably missing a few bits, but you get my point.  Whether you call it VCE Vblock, IBM Dynamic Infrastructure, NetApp Virtualise Everything, HP Converged Infrastructure, they’re all articulations of a virtualised datacentre.  We’re headed towards integrated and virtualised datacentres and one of the fascinating things about IT is stick around long enough and you’ll see the same ideas come back round.  We deconstructed the mainframe in pursuit of open systems, but now open systems are creaking under the load of data proliferation and low utilisation.  What to do?  Well, reconstruct the mainframe conceptually using integrated open systems.  And that’s what customers want …not necessarily flashy marketing schtick, but, rather a self healing/self tuning, policy based datacentre which allows customers to flex up/down depending upon market conditions with predictable and best costs and then sits invisibly in the corner and behaves!

2. Innovative products continue the march to becomes universal features.

There was a time when thin provisioning, data deduplication, disk spindown for underutilised disks, and automated storage tiering were products in their own right.  But if a product is so great that it demonstrably reduces costs and increases utilisation, shouldn’t it be a feature?  Exactly.  Which is why 2009 saw EMC, IBM, NetApp, HP, and HDS introduce or extend these technologies as features in their product sets.  And I don’t think that the list will stop there as I expect to see data compression enter as a feature in primary storage in 2010 as well.  Why should we care?  As features within an infrastructure we can use these technologies holistically, whether in a ‘branded’ virtualised datacentre or one composed of open products which work together seamlessly, to deliver storage at the most appropriate cost from creation to cremation with zero disruption to production business.

3. Server and desktop virtualisation are no longer incorrectly viewed as workloads.

VMware and Microsoft Hyper-V are good examples of server virtualisation, whilst VMware View and Citrix XenDesktop are good examples of desktop virtualisation.  Virtualisation of physical resources undoubtedly delivers higher utilisation and cost benefit, however virtualisation is a technology not a workload.  What’s the difference?  A workload is what you do with the technology, and everyone will do something slightly different with their workload based upon their business needs.  If you forget that and leave out the storage design and tuning, you may fail to achieve cost benefit at best or have to abandon the project at worst.  Don’t believe me though, have a read of this blog post by Chad Sakac, worldwide VP of VMware and all round virtualisation guru who is intimately involved with such deployments worldwide.

4. Grid storage / scale out storage take hold and never look back.

IBM XiV, EMC Vmax, NetApp ONTAP v8 …don’t look now, but everybody’s going grid.  Will it solve global warming, introduce world peace, and cuddle baby seals?  Not exactly.  But it will introduce self healing/tuning highly efficient and utilised storage at attractive price points using commoditised components …and become the bedrock of the virtualised datacentre.

5. Automation, automation, automation.

What use are virtualised servers, virtualised desktops, virtualised applications, self healing/tuning storage systems if you have to provision and manage them manually?  Precisely.  If you can’t automate it, chances are it will be left behind in the march towards the virtualised datacentre.  But don’t stop there as pure automation should give rise to …

6. Automation gives birth to policy based storage.

Remember aligning data to business value?  Of course you did!  Automation will remove the manual nature of managing IT and related resources, but customers don’t just want a conveyer belt of chocolates with Lucy and Ethel.  Automation which allows us to align a customer SLA and/or business value is what we truly want to deliver …policy based movement of data with zero disruption.

7. Customers continue to interact openly and publicly.  Are we listening?

Customers are speaking with us and our vendor partners publicly and openly in ways that we never could have anticipated through the use of technologies such as Twitter and blogs.  If you think that Twitter is just a platform for people to tell you what they’ve had for breakfast, you’ve missed the point entirely.  These platforms are a way for end users/customers to interact with one another as well as business partners efficiently. Storagebod, an end user at a major media company, took the time to write six individual letters to Father Christmas regarding what he would like to see from vendorsIanhf, an influential end user at a major telecoms company, took the time to write about what he expects from business partners.  Think you’re Elite?  See if you can get through all 17 of Ianhf’s points saying ‘yes, we/I do that’.  I’m not sure that I can, and that’s the point …by actively reading and engaging with what our customers are saying we and vendors have two choices …ignore it and continue making products / delivering services which customers find shoddy, or listen and strive to evolve and provide the products / services / solutions which make a difference to them in a positive way.  I know which one I’ll be choosing in 2010, otherwise we’re left just talking to ourselves and what fun or use is that?  Ignore customer public sentiment at your peril, as it would seem AT&T did in the USA with iPhone users.

8. England win the World Cup, Watford FC are promoted to the Premiership, and Mrs. PL stops yelling at me for snoring.

Okay, I kinda made that last one up but a PL can dream can’t he?  And who knows what 2010 will bring but what I do know is this …England, Watford FC, indeed all of us are in control of our destiny for the year ahead.

Have a great Christmas / Hanukkah / Diwali / Eid / Kwanzaa / Christmaskah / Festivus …none of the above …enjoy your holiday with your family and see you in 2010.

I’m off to light the last Hanukkah candle with Mrs. PL, PL Junior …and anxiously await the arrival of the Hanukkah Armadillo.

1984 revisited.

28/08/2009

I remember watching the Super Bowl XVIII with my father in 1984 when, unexpectedly during an otherwise boring third quarter, an advert came on which would change the way we think about computing forever.  The advert was directed by Ridley Scott …who would go on to make such classics as Blade Runner, Alien, and Gladiator …cost millions of dollars and months to make, lasted exactly sixty seconds, and was shown exactly …once.  I remember watching the advert speechless and wishing to see it again …but I wouldn’t see it again until many years later when You Tube made such things possible.

I won’t go into the advert in any great detail as it deserves to be seen and digested [click here to view], but it purported to introduce the Apple Macintosh to the world on 24 January 1984.  What it actually did was fire the first salvos of the ‘open system’ movement against the traditional mainframe world.  My father, who was an executive in the ‘data processing’ department …Information Technology, or ‘IT’ didn’t exist yet …watched the advert, turned to me, and proceeded to tell me how we would someday watch movies without going to the cinema, watch any movie ever made when and where we wanted to, listen to any piece of music ever recorded when and where we wanted to …and carry the sum total of the world’s library content in our pockets.

Now, my old man was heavy into Star Trek [still is, as am I, and I’ve passed on this geekdom to PL Junior!] and I have to admit that, at the time, I thought he had been watching one too many episodes with JT Kirk and the boys and/or had had one too many G&Ts during the course of the Super Bowl.  I nodded politely and went back to noshing on the nachos and sour cream my mum had made.

What has this got to do with Data Storage and Protection?

Far from being doolally, my father was describing things to me in 1984 that we now take for granted.  iPods, You Tube, Spotify, e-ink eReaders …all have become reality and, it is projected that within 15 years we will have personal storage systems capable of holding the contents of all of the world’s libraries in a form factor small enough to fit in your pocket.  Really.  But how did my father predict such things?  Was he a futurist who missed out on the big time?  Sadly, no.  He went to uni with people who would go on to work for DARPA and they would often sit up late into the evening over G&Ts discussing the latest developments in data networking technology.  They could see the practical applications of the internet they were developing, and I would argue that there are many parallels to be found in the success of the internet and the future of data storage.

The internet was not originally designed to be the delivery mechanism for fine purveyors of pornography but, rather, a way for the US government and military to communicate from coast to coast and all throughout the US in the event of WWIII …and the Soviet Union had wiped entire communication nodes …and cities …off the map with nuclear weapons.  It is a system that is designed to fail …a resilient system which can continue to operate even after multiple and massive failures.  Another interesting feature of the internet is it is designed to use standard ‘off the shelf’ components such that, as the components’ quality and processing power increases, they can be put into the internet without having to take down or redesign the whole flippin’ thing.  Think dial up modem to ‘wired’ broadband to ubiquitous WiFi and you get the picture.

A similar revolution is happening in storage.  The original storage arrays were really more like massive servers on steroids …in fact, they looked and behaved much like the mainframes they were meant to replace.  They have a central processor known as a controller, cache which acts much like the memory in a server, and well …disks.  The disks provide the massive and shared storage, but are connected to the controllers and cache.  A great architecture to start with, but as the amount of data we are creating has exploded exponentially it has become less and less efficient and more difficult to manage.  Indeed, whilst functionality has been added to the architecture …data replication, modular arrays, iSCSI, NAS, and so on …the central principle of architecture design hasn’t changed all that much in quite a while.  Most importantly, they are designed to never fail …and as a result of that principle, we find ourselves in something programmers call an ‘infinite loop’ which becomes ever more expensive to manage.

So what’s the answer?  Well, we need to turn the central principle on it’s head and design systems which fail.  Now, I know that may seem counterintuitive, but bear with me.  The quality of standard components has increased significantly over the past ten years …we now have hard drives and Intel processors in our laptops which would have powered supercomputers ten years ago …but, things still fail from time to time.

My view is parallel processing or ‘grid architecture’ storage is the answer, and these systems will soon eclipse the traditional storage architectures.  What is grid architecture storage?  The specifics can be somewhat complicated, but in principle you have data and communication modules which replace the controllers and cache with software to connect all of the modules together.  What does this give us?  The ability to use algorithms which write data to all of the data drives simultaneously …and as each module uses standard components with CPU and memory on board, I can lose a module without losing data as well as increasing system performance by replacing the standard components with the new whizz bang models as they become available.  The secret sauce of the software which connects the modules is what allows us to provide performance and reliability equivalent or greater to traditional systems …at an acquisition and management cost much lower than traditional storage systems.

So who is using grid architecture?  If you have Googled anything recently, you’ve used grid storage architecture.  And, if grid storage is the answer, who makes it?  Well, IBM XiV was the first past the mark but now EMC Vmax has joined the scene …and NetApp, HDS, HP aren’t far behind.  What will set each of them apart, in my opinion, is how they implement grid architecture as well as the functionality they provide as standard.

If you aren’t thinking about grid architecture storage, you should be …this is a tidal wave which is already transforming the storage marketplace and, whilst we  have ‘first mover’ advantage with the promise of fair pricing at the moment this won’t last forever.

Please feel free to contact me if I can help you understand grid architeture more fully and in greater depth, including the very real cost savings which can be gained.

I need to learn Norwegian!

14/08/2009

I need to be brief with this Weekly View as it is PL Junior’s birthday today, and Mrs. PL has made it quite clear that I am required to help setup for his party …and ensuring I don’t bore our guests with analogies of birthday cake slices and how they remind me of data deduplication.

But with guests coming over later this evening, I got to thinking again about our recent holiday.  As I said last week, this is the second year running that we went to the same resort in Malta on holiday.  Last year PL Junior as just learning how to swim and, as he was just turning two, wasn’t yet to the point where he would play with children he didn’t know.  Equally, as only about twenty percent of the folks holidaying in this resort are British, there were many children speaking a multitude of languages that PL Junior didn’t understand.  This year saw many changes, from PL Junior spending nigh on six hours a day in the pool and, interestingly PL Junior developed a relationship with three Norwegian children whom he played with non stop.  Did PL Junior suddenly become a fluent Norwegian speaker?  Nope, didn’t understand a word of what the three children aged three, five, and nine were saying …nor they him …but between my German, my wife’s French, and the Norwegian parents’ English we were able to find enough common ground to enable us to go out to dinner together and generally enjoy one another’s company.  PL Junior continues to ask for Markhus, Khristof, and Nikolay and when we are going to go back to Malta to play with them …and Mrs. PL and I have a standing invitation to come to Norway with PL Junior to ski in their family chalet.

What does this have to do with data storage and protection?

The sale of enterprise [e.g. EMC Symmetrix] and modular storage [e.g. EMC CLARiiON] ‘crossed over’ during the last recession in 2000 / 2001, with modular storage sales overtaking enterprise for the first time and, since then, modular storage sales have continued to rise whilst enterprise have continued to decline.  There are many reasons for this, but customers realised that they could achieve similar performance and reduced complexity with modular storage at a price significantly lower to enterprise.  We are about to see a similar ‘paradigm shift’ as enterprise and modular storage converge.  You can tell your friends that you heard it here first, and there are storage products on the market today which represent the future converged enterprise/modular arrays as I’ve described …think IBM XiV and EMC Vmax …and trust me when I tell you that other major vendors such as NetApp, HDS, and HP aren’t far behind.

As the storage arrays converge we will be able to provide customers performance, high utilisation, and decreased management complexity without sacrificing quality and, perhaps most importantly, at a competitive cost.  But as this convergence occurs, how will customers be able to differentiate one solution from another to satisfy their business needs …or will they all look the same?

No, I can assure you that, whilst they will seek to achieve the same outcomes, how they get there will continue to be different.  IBM XiV solves the grid architecture question by using a massively parallel SATA array and using software to allow storage to be ‘written‘ across all the drives thus giving high performance to all applications equally …whereas EMC takes a different view with Vmax useing mixed solid state drives, fibre channel drives, and SATA drives with software to ‘promote‘ and ‘demote‘ storage as application demands require.  Equally, storage vendors will seek to differentiate their products with features …whilst they will all provide thin provisioning, vendors are now going to war re how their thin provisioning works.  To wit, they go to great pains to explain ‘chunklets’, or how large a thin provisioned block they will use.  It is now being argued that use a chunk too large and you may negate the very applicability of thin provisioning long term, whereas use a chunk too small and you may overrun the onboard storage cache and negatively affect performance.  HDS uses 42 MB chunk sizes to allow for their thin provisioning solution to execute zero page reclamation, thus ‘reclaiming’ up to 30% of previously allocated storage back into the storage pool as fully usable …thus equating to cost savings …whilst EMC uses 768K chunklets as this is optimised for performance on their systems.

Who is right and, more importantly …what to do?  Firstly, they are all correct …and all incorrect!  The solutions will all technically ‘work, however what matters is what the customer is trying to accomplish and the business issue(s) we are trying to solve.  This is where Computacenter comes in as our vendor agnostic yet vendor selective consultancy practice enables us to firstly understand how each of our vendor partners accomplish things like grid architecture, thin provisioning, and chunklet size …and secondly, which vendor or vendors can demonstrably solve the customer business issue(s).  Just like PL Junior and our new Norwegian friends, there are folks who can translate what is being said at the bits an bytes level into real world cost reduction and the solving of business issues.

What sometimes happens, however, is that the most applicable solution could actually involve more than one vendor …but as we’re trying to reduce complexity, not introduce more many customers decide to go ‘sole vendor’.  Again, this is where Computacenter come in as …just as we parents helped PL Junior and the Norwegian children understand one another …Computacenter can provide consultancy, implementation, and support services which span multiple vendors thus providing customers with the best of breed solution at a fair cost without increasing complexity.

Mrs. PL and PL Junior have already stated their intention for us to holiday with our new Norwegian friends next year, and I plan to work a bit more on my Norwegian before we go away.  In the interim, please don’t hesitate to contact me if I can be of any assistance in helping to articulate the ‘why Computacenter’ for you  …our customers.

Have a great weekend.
