Is the new Netapp the old IBM?

When you hang out with car salesmen you start thinking station wagons are cool…

When you think station wagons are cool, you watch the big screen through your windshield…

And when you watch the big screen through your windshield, you watch educational movies about mainframe computers

And when you watch educational films about mainframes you get lost in mainframeland…..

And when you get lost in mainframeland you start seeing Netapp filers….

 

And when you start seeing Netapp filers, you take a trip through a wormhole…

 

And when you travel through a vortex you become a supernova baby…

Don’t become a supernova baby.

Some gigabytes are worth more than others

Getting clarity on the cost and relative worth of enterprise technology has always been a challenge because of the complex environments and diverse requirements involved. For every good question about which product is better, there is the almost universal answer – “it depends”.  One product might have more capacity than it’s competitors, while another might have a unique feature that supports a new application and another product might have a new operating or management approach that increases productivity.  Beauty is in the eye of the beholder and enterprise customers dig a lot deeper than what appears in competitors’ spec sheets. In some respects, it’s like comparing real estate properties where location and design trump square footage.

One of the traps people fall into when comparing the value of cloud services to legacy infrastructure technologies is limiting their analysis to a direct cost per capacity analysis. This article in Information Week did that in a  painstaking way where the author, Art Wittman, made a commendable effort to make a level cost comparison, but he left out the location and design elements.  He concludes that IaaS services are not worthwhile because the costs per capacity are not following the same cost curve as legacy components and systems.  There is certainly some validity to his approach – if the capacity cost of disk drives has dropped an order of magnitude in four years, why should the cost of Amazon’s S3 service be approximately 39% higher?

Conceding that productivity gains can be realized from cloud services, he limits their value to application services and summarily rejects that they could apply to IaaS. After all the work he had done to make a storage capacity cost comparison, he refused to factor in the benefits of using a service.  Given that omission, Mr. Wittman concludes there is no way for an IaaS business model to succeed.

I agree with Mr. Wittman in one respect, if a service can’t be differentiated from on-site hardware, then it will fail.  But that is not the case with enterprise  cloud storage and it is especially not true with cloud storage that is integrated with local enterprise storage. Here’s why:

Storage is an infrastructure element, but it has specialized applications, such as backup and archiving that require significant expense to manage media (tapes). Moving tapes on and off-site for disaster recovery purposes is time-consuming and error-prone. While the errors are usually not damaging, they can result in lost data or make it impossible to recover versions of files that the business might need. The cost of lost data is one of those things that is very difficult to measure, but it can be very expensive if it involves data needed for legal or compliance purposes.  Using cloud storage as virtual tape media for backup kills two birds with one stone by eliminating physical tapes and the need for off-site tape rotations. It still takes time to complete the backup job and move data to the cloud, but many hours a month in media management can be recaptured as well as tape-related costs.

There are even greater advantages available with backup if it can be integrated from primary storage all the way to the cloud, as it is with StorSimple’s cloud-integrated enterprise storage (CIES).  Using snapshot techniques on CIES storage, the amount of backup data generated is kept to a minimum, which means the amount of storage consumed from the storage cloud service provider is far less than if a customer used the cloud for virtual tape backup storage. Cloud-resident data snapshots have a huge capacity advantage over backup storage where the storage of files for legal and compliance purposes are concerned and it demonstrates how the design of a cloud appliance can deliver even more value from cloud storage.

The next increase in cloud storage value comes from integrating deduplication, or dedupe technology with cloud storage.  Dedupe minimizes the amount of storage capacity consumed by data by eliminating redundant information within the data itself. Sometimes, the amount of deduped data can be quite large – as occurs with virtualized systems. StorSimple’s CIES systems automatically applies dedupe to the data stored in the cloud and squishes capacity consumption to its minimum level – which also minimizes the amount of data that is transferred to and from the cloud. With the help of a cloud-integrated enterprise storage system, the capacity of cloud storage increases in value a lot because so much less of it is consumed.

But the worth of cloud storage is not all about consuming capacity, it’s about accessing data faster than you can from legacy data archives. Data stored in the cloud with a CIES system is online and can be accessed by workers and administrators without the need to find it in a separate archive pool of storage. If you don’t work in IT, you might not know how much time that can save the IT staff, but if you do work in IT, you know this is a huge advantage that returns a lot of administrator time for other projects.

The access to data in cloud storage is probably most valuable when it occurs following a disaster.  Cloud storage provides the ultimate flexibility in recovery by being location-independent.  Backup or snapshot data stored in the cloud can be accessed from almost any location with an Internet connection to the cloud storage service provider.  Again, cloud-integrated storage has some important advantages that further increase the value of cloud storage by requiring only a small subset of the data to be downloaded before application systems can resume production work. This is much faster than downloading multiple virtual tapes and then restoring data to application servers.

I could go on – and I will in future blog posts. This one is long enough already. There are numerous ways that cloud storage is worth more than it’s raw capacity.  Some of this worth comes from its role in disaster recovery but a lot of it comes from how it is used as part of an integrated storage stack that incorporates primary, backup, archive and cloud storage.

Introducing Run! A podcast about high tech, what we do with it and what it does to us

I started a new podcast, called “Run!” with my friends Matt Brender from Boston and Roger Strukhoff from Sterling Illinois. We represent different geographies and generations and we should always be able to find good things to disagree on.  A few things we DO agree on are that technology is fascinating even though it doesn’t always make things better and that the changes it makes on us are indelible.  That’s what we’ll be exploring on Run!;  technology, how to use it effectively and what to watch out for.

Guests will be an important part of Run!  and we look forward to finding out what works for them and what bothers them.
