software-defined storage

NEWS ANALYSIS: The definition of software-defined storage is in the eye of the beholder. As SDS evolves, opportunities for the channel have never been greater.

Also employing SDS to manage data at scale is Cleversafe, which makes use of software to slice data up in a way that improves scalability and makes that data more secure.

"Innovation now takes place in the software using commodity hardware," said Cleversafe CEO John Morris. "You have to be able to have an abstraction of the policy layer."

Caringo, meanwhile, has developed an approach to scaling an SDS platform that reduces costs by eliminating the need for a controller.

"We rely on standard x86 systems running Linux," said Adrian Herrera, senior director of marketing for Caringo. "Multiple nodes then make up what we call a Swarm."

Meanwhile, incumbent storage vendors such as EMC are keenly aware of the significance of SDS, but view the rise of SDS as more evolutionary than revolutionary.

"The intelligence is clearly going to be in the software," said Sal DeSimone, CTO of the Advanced Storage Division of EMC. "It will happen in stages."

In the case of EMC, that first stage is ViPR, a next-generation controller that creates a data plane that isolates the management of data from the underlying physical hardware.

NetApp, meanwhile, argues that the shift to SDS has already been under way for years. NetApp CTO Jay Kidd said what is really changing is the degree to which SDS can be applied to manage storage at scale. As such, Kidd contends that data management in the age of the cloud will come down to the resiliency of the software being used to manage it.

"Almost anybody these days can build a software-defined system," said Kidd. "The challenge is to be able to build resiliency into the software in a way that manages data at scale."

To that particular end, Kidd said that NetApp has been invested heavily in developing Clustered Data OnTap, which is designed to manage data at scale across private and public cloud computing environments.

At the same time, vendors such as HP said they see the shift to SDS as an opportunity to gain market share at the expense of established rivals. HP created a data mobility capability, called 3Par Online Import, that reduces storage switching costs by making it simpler to migrate data from one storage system to another.

"Data mobility is about making the upgrade process non-disruptive," said Vish Mulchand, director of solutions marketing for HP Storage. "It's now easier to upgrade from the existing versions of EMC's VNX system to HP 3Par StoreServ storage than it is to upgrade to the newest version of VNX."

For solution providers in the channel, technology transformations on this scale eventually create new opportunities. The challenge now is figuring out when those opportunities are going to be ripe.

The good news is that not only are customers struggling with more data than ever, they are keenly interested in having a more agile IT capability. In fact, the quest for that agility is driving not only much of the interest in SDS, but also all other things software-defined across the enterprise.

Of course, the degree to which SDS or any other form of software-defined anything will hold up as a separate distinct category of anything remains to be seen.

The one thing that is for certain is that as SDS continues to evolve, the opportunities for the channel surrounding storage have never been greater.
