SNIA’s Events Strategy Today and Tomorrow

khauser Leave a comment

David Dale, SNIA Chairman

Last month Computerworld/IDG and the SNIA posted a notice to the SNW website stating that they have decided to conclude the production of SNW.  The contract was expiring and both parties declined to renew.  The IT industry has changed significantly in the 15 years since SNW was first launched, and both parties felt that their individual interests would be best served by pursuing separate events strategies.

For the SNIA, events are a strategically important vehicle for fulfilling its mission of developing standards, maintaining an active ecosystem of storage industry experts, and providing vendor-neutral educational materials to enable IT professions to deal with and derive value from constant technology change.  To address the first two categories, SNIA has a strong track record of producing Technical Symposia throughout the year, and the successful Storage Developer Conference in September.

To address the third category, IT professionals, SNIA has announced a new event, to be held in Santa Clara, CA, from April 22-24 – the Data Storage Innovation Conference. This event is targeted at IT decision-makers, technology implementers, and those expected to influence, implement and support data storage innovation as actual production solutions.  See the press release and call for presentations for more information.  We are excited to embark on developing this contemporary new event into an industry mainstay in the coming years.

Outside of the USA, events are also critically important vehicles for the autonomous SNIA Regional Affiliates to fulfill their mission.  The audience there is typically more biased towards business executives and IT managers, and over the years their events have evolved to incorporate adjacent technology areas, new developments and regional requirements.

As an example of this evolution, SNIA Europe’s events partner, Angel Business Communications, recently announced that its very successful October event, SNW Europe/Datacenter Technologies/Virtualization World, will be simply known as Powering the Cloud starting in 2014, in order to unite the conference program and to be more clearly relevant to today’s IT industry. See the press release for more details.

Other Regional Affiliates have followed a similar path with events such as Implementing Information Infrastructure Summit and Information Infrastructure Conference – both tailored to meet regional needs.

The bottom line on this is that the SNIA is absolutely committed to a global events strategy to enable it to carry out its mission.  We are excited about the evolution of our various events to meet the changing needs of the market and continue to deliver unique vendor-neutral content. IT professionals, partners, vendors and their customers around the globe can continue to rely on SNIA events to inform them about new technologies and developments and help them navigate the rapidly changing world of IT.

Trends in Data Protection

Data protection hasn’t changed much in a long time.  Sure, there are slews of product announcements and incessant declarations of the “next big thing”, but really, how much have market shares really changed over the past decade?  You’ve got to wonder if new technology is fundamentally improving how data is protected or is simply turning the crank to the next model year.  Are customers locked into the incremental changes proffered by traditional backup vendors or is there a better way?

Not going to take it anymore

The major force driving change in the industry has little to do with technology.  People have started to challenge the notion that they, not the computing system, should be responsible for ensuring the integrity of their data.  If they want a prior version of their data, why can’t the system simply provide it?   In essence, customers want to rely on a computing system that just works.  The Howard Beale anchorman in the movie Network personifies the anxiety that burdens customers explicitly managing backups, recoveries, and disaster recovery.  Now don’t get me wrong; it is critical to minimize risk and manage expectations.   But the focus should be on delivering data protection solutions that can simply be ignored.

Are you just happy to see me?

The personal computer user is prone to ask “how hard can it be to copy data?”  Ignoring the fact that many such users lose data on a regular basis because they have failed to protect their data at all, the IT professional is well aware of the intricacies of application consistency, the constraints of backup windows, the demands of service levels and scale, and the efficiencies demanded by affordability.    You can be sure that application users that have recovered lost or corrupted data are relieved.  Mae West, posing as a backup administrator, might have said “Is that a LUN in your pocket or are you just happy to see me?”

In the beginning

Knowing where the industry has been is a good step in knowing where the industry is going.  When the mainframe was young, application developers carried paper tape or punch cards.  Magnetic tape was used to store application data as well as a media to copy it to. Over time, as magnetic disk became affordable for primary data, the economics of magnetic tape remained compelling as a backup media.  Data protection was incorporated into the operating system through backup/recovery facilities, as well as through 3rd party products.

As microprocessors led computing mainstream, non-mainframe computing systems gained prominence and tape became relegated to secondary storage.  Native, open source, and commercial backup and recovery utilities stored backup and archive copies on tape media and leveraged its portability to implement disaster recovery plans.  Data compression increased the effective capacity of tape media and complemented its power consumption efficiency.

All quiet on the western front

Backup to tape became the dominant methodology for protecting application data due to its affordability and portability.  Tape was used as the backup media for application and server utilities, storage system tools, and backup applications.

Backup Server copies data from primary disk storage to tape media

Customers like the certainty of knowing where their backup copies are and physical tapes are comforting in this respect.  However, the sequential access nature of the media and indirect visibility into what’s on each tape led to difficulties satisfying recovery time objectives.  Like the soldier who fights battles that seem to have little overall significance, the backup administrator slogs through a routine, hoping the company’s valuable data is really protected.

B2D phase 1

Backup Server copies data to a Virtual Tape Library

Uncomfortable with problematic recovery from tape, customers have been evolving their practices to a backup to disk model.  Backup to disk and then to tape was one model designed to offset the higher cost of disk media but can increase the uncertainty of what’s on tape.  Another was to use virtual tape libraries to gain the direct access benefits of disk while minimizing changes in their current tape-based backup practices.  Both of these techniques helped improve recovery time but still required the backup administrator to acquire, use, and maintain a separate backup server to copy the data to the backup media.

Snap out of it!

Space-efficient snapshots offered an alternative data protection solution for some file servers. Rather than use separate media to store copies of data, the primary storage system itself would be used to maintain multiple versions of the data by only saving changes to the data.  As long as the storage system was intact, restoration of prior versions was rapid and easy.  Versions could also be replicated between two storage systems to protect the data should one of the file servers become inaccessible.

This procedure works, is fast, and is space efficient for data on these file servers but has challenges in terms of management and scale.  Snapshot based approaches manage versions of snapshots; they lack the ability to manage data protection at the file level.  This limitation arises because the customer’s data protection policies may not match the storage system policies.  Snapshot based approaches are also constrained by the scope of each storage system so scaling to protect all the data in a company (e.g., laptops) in a uniform and centralized (labor-efficient) manner is problematic at best.

CDP

Writes are captured and replicated for protection

Continuous Data Protection (both “near CDP” solutions which take frequent snapshots and “true CDP” solutions which continuously capture writes) is also being used to eliminate the backup window thereby ensuring large volumes of data can be protected.  However, the expense and maturity of CDP needs to be balanced with the value of “keeping everything”.

 

 

An offer he can’t refuse

Data deduplication fundamentally changed the affordability of using disk as a backup media.  The effective cost of storing data declined because duplicate data need only be stored once. Coupled with the ability to rapidly access individual objects, the advantages of backing up data to deduplicated storage are overwhelmingly compelling.  Originally, the choice of whether to deduplicate data at the source or target was a decision point but more recent offerings offer both approaches so customers need not compromise on technology.  However, simply using deduplicated storage as a backup target does not remove the complexity of configuring and supporting a data protection solution that spans independent software and hardware products.  Is it really necessary that additional backup servers be installed to support business growth?  Is it too much to ask for a turnkey solution that can address the needs of a large enterprise?

The stuff that dreams are made of

 

PBBA

Transformation from a Backup Appliance to a Recovery Platform

Protection storage offers an end-to-end solution, integrating full-function data protection capabilities with deduplicated storage.  The simplicity and efficiency of application-centric data protection combined with the scale and performance of capacity-optimized storage systems stands to fundamentally alter the traditional backup market.  Changed data is copied directly between the source and the target, without intervening backup servers.  Cloud storage may also be used as a cost-effective target.  Leveraging integrated software and hardware for what each does best allows vendors to offer innovations to customers in a manner that lowers their total cost of ownership.  Innovations like automatic configuration, dynamic optimization, and using preferred management interfaces (e.g., virtualization consoles, pod managers) build on the proven practices of the past to integrate data protection into the customer’s information infrastructure.

No one wants to be locked into products because they are too painful to switch out; it’s time that products are “sticky” because they offer compelling solutions.  IDC projects that the worldwide purpose-built backup appliance (PBBA) market will grow 16.6% from $1.7 billion in 2010 to $3.6 billion by 2015.  The industry is rapidly adopting PBBAs to overcome the data protection challenges associated with data growth.  Looking forward, storage systems will be expected to incorporate a recovery platform, supporting security and compliance obligations, and data protection solutions will become information brokers for what is stored on disk.
