EMC provides SDS solutions for scale-out SAN (ScaleIO), hyper-scale object, Hadoop HDFS analytics (Elastic Cloud Storage – ECS) and software defined management and automation solutions (< a href="http://www.emc.com/vipr">ViPR SRM, ViPR Controller). These tools can manage a multi-vendor storage environment from one screen and provide an open API cloud orchestration layer for virtualized data centers, including a conduit to private and hybrid clouds. The individual components can be deployed independently, while ViPR delivers storage automation and an API for cloud integration.

ScaleIO is a software-defined, server-based storage area network (SAN) that converges storage and compute resources, and it can grow from a few to thousands of servers. ECS is a software-defined cloud storage platform that combines commodity infrastructure with traditional arrays. ViPR SRM is software-defined management software that enables IT to visualize storage relationships, analyze configurations and capacity growth, and optimize resources. ViPR Controller is automation software that centralizes multivendor storage.

“SDS is about addressing needs around performance, data management, and the end user experience and aligning the right data to these needs for the right cost,” said Suresh Sathyamurthy, Senior Director of Product Marketing, Emerging Technology Division, EMC. “In the end, it’s about greater flexibility, agility and vendor choice.”


NetApp has invested heavily in its DataOnTap storage operating system so it makes sense that it would build its SDS approach on this solid foundation. For example, it released NetApp StorageGrid Webscale for object storage and integration of cloud applications with Amazon S3. It is said to be able to store up to 100 billion objects in one container that can be distributed in data centers spread around the planet.

“Leveraging 10 years of enterprise object-storage experience, StorageGRID Webscale provides a foundation for software-defined, globally distributed object stores with policies that enable IT to govern data placement and protection worldwide,” said Dan Neault, senior vice president, Data Center Solutions Group, NetApp.


DataCore has probably been doing SDS longer than anyone. And it is reaping the benefits of increased awareness of the value of SDS. George Teixeira, the company’s CEO and President, said the result of this raised awareness was the fact that his company has now shipped over 25,000 copies of its software. DataCore has been playing the software-based tune for quite some time, and now it appears that it has struck gold.

DataCore promotes its long experience with storage virtualization and features such as automation that supports auto-discovery, load balancing, auto-tiering and self-healing. Its software-defined platform comprises two products; one for managing SAN/NAS and cloud storage (SANsymphony-V) and the other for hyper-converged storage (Virtual SAN). Since they are built on the same platform, they are integrated such that capacity can be shared across them.

“The platform has been developed to provide the highest levels of storage availability, performance and efficiency from a utilization and a management perspective,” said Teixeira.

In addition, DataCore is working with Huawei on a line of jointly certified hyper-converged solutions. The first result of the partnership between the two companies combines Huawei’s FusionServer series with SANsymphony. You can also add Huawei’s Oceanstor SSD storage and existing storage systems via iSCSI or Fibre Channel connectivity.


NexentaConnect is a suite that combines SDS with cloud and desktop features to provide features such as performance acceleration, automation and analytics. NexantaStor is the storage component and it delivers unified file and block storage services that run on commodity hardware. It is said to simplify storage management and to scale from tens of TBs to PBs.

Michael Letschin, Director of Product Management Solutions, Nexenta, also talked about added elements of the suite. NexentaEdge (beta), he said, is object, file and block storage for OpenStack and big data applications. It delivers Cinder Block and Swift/S3 object storage services, and it integrates through a Horizon management plug-in to streamline storage management and capacity planning. This element will add storage defined networking capabilities to the SDS side. Finally, NexentaFusion (beta) adds more analytics as well as orchestration software.

“This automates arrangement, coordination and management of complex compute systems, data stores and services without the need for administrators to pre-define the nature and placement of data,” said Letschin.
