Nexenta products are available in many languages and character sets, such as Japanese, Chinese, and Russian, and are sold worldwide.

Beginning in 2004, Alex Aizman and Dmitry Yusupov wrote the iSCSI storage stack, as well as founding the Open iSCSI development community ( In 2005, they saw the opportunity to pioneer by combining components of Linux with the OpenSolaris and Open Storage codebases and founded Nexenta. As a result of being one of the earliest companies to work in this area, Nexenta’s products were among the first open source storage products to be brought to market in mid-2008. Nexenta’s core storage platform, NexentaStor™, is a software-only storage operating system and a storage-optimized file system based on OpenSolaris / OpenStorage ZFS technology. With this unique combination, NexentaStor delivers ease-of-use and developer friendly aspects in tandem with the power and scalability needed for enterprise class storage. Nexenta products, built on top of the NexentaStor platform, provide unparalleled capabilities in managing multivendor environments, extreme efficiencies in storage administration and management, and core storage capabilities for content management, compliance, and more.

NexentaStor Integration

With best in class VMware integration, NexentaStor is designed with a multi-tenant VMware vCenter Plug-in and VMware Virtual Volume (VVOL) support. The VMware vCenter Web Client Plugin simplifies day-to-day operational tasks for VMware Administrators by allowing customers to incrementally scale storage by adding datastores from within the vCenter interface, identifying performance bottlenecks and reviewing capacity utilization trends.

Integration with vCenter’s role-based authentication mechanism provides an added level of segmentation and security options for multi-tenant solutions, branch offices and even departmental storage solutions. It is a perfect complement for NexentaStor 5.0 VMware Virtual Volume support, allowing all storage operations on NexentaStor to be performed with Virtual Machine granularity.

We also offer advanced support for Docker, via the Docker volume driver, and full support for OpenStack, with OpenStack Cinder drivers for iSCSI and NFS for a broad set of OpenStack releases, you are able to easily snap in NexentaStor into a variety of use cases and take advantage of the innovation happening in the data center.

NexentaEdge is specifically designed from the ground-up to deliver the performance, data integrity and storage functionality required for primary storage applications and virtual machines.

It is powered by advanced data reduction technologies, including cluster-wide inline deduplication, compression and Quick Erasure Coding (Quick EC). Quick EC technology reduces the storage overhead required to maintain the redundancy of data across servers, without affecting read or write performance. In addition, NexentaEdge is fully integrated with Docker Datacenter deployments and enables users to seamlessly deploy storage and application services as containers across servers.

NexentaEdge Delivers:

  • Multi-service scale-out platform delivering iSCSI block, NFS file and S3 and Swift object services
  • Simple to manage web-based GUI for daily management and service provisioning
  • Quick Erasure Coding technology, manages both active and cold object archives with speed and high storage efficiency
  • Superior data protection with cluster-wide inline deduplication, compression and unlimited snapshots/clones
  • Scale-out platform for Docker Container-Converged infrastructure with seamless integration with Docker Universal Control Plane for single pane of glass management of containerized applications
  • High performance, all-flash deployment profiles with support for SSD SATA, SAS and NVMe-based storage SSDs
  • Shared namespace between File and Object Storage

What is Quick Erasure Coding (QEC)?

NexentaEdge’s Quick Erasure Coding (Quick EC) technology reduces the storage overhead required to maintain the redundancy of data across servers, without affecting read or write performance. Quick EC eliminates the performance penalty usually associated with accessing objects in traditional erasure coded solutions and is especially beneficial, for large capacity S3 object clusters.

  • Designed for efficient storage of cold data without compromising on performance
  • Encoding is done in the background using post-processing tasks
  • Innovative approach avoids read penalty of traditional erasure coding

Big Data Solution

 Making Big Data Work: Storage is the Key to Exponential Data Growth

With big data, companies are generating breakthrough insights and analysis like never before. Yet they are stymied by how to store and extract the maximum value from vast volumes of raw, unstructured data piles. If you’re going to collect terabytes, and even petabytes, of business-impacting information, you need to store it smartly. Traditional storage products and architectures might no longer be technically or financially suitable to provide the scale needed to support this new paradigm.

Since receiving its Royal Charter in 1961, the University of Sussex has become a leading teaching and research institution. The IT department provides support for the entire university, its staff and students.

 Queen Elizabeth’s Grammar School

The school recently was struck with the common issue of effectively storing increasingly growing amounts of data. The school’s aging Intel SAN storage solution was rapidly reaching capacity and, as a result, was slowing down and not providing the performance required.Under pressure to make the most out of the school’s allocated IT budget, Mr. Munro enlisted the help of high performance computing specialists VA Technologies.The aim was to find a flexible and reliable storage solution at a competitive price—one that would significantly upgrade the storage infrastructure, increase performance, and not overwhelm the IT staff with technical issues.

 North Devon Homes

In its role of providing support and care for residents, North Devon Homes realised that housing data is an integral part of the process. The housing association’s systems were almost completely virtualised but its direct attached storage had no resilience and was affecting uptime. The amount of data North Devon Homes needed to store was growing at a steady pace and there was a requirement to keep it for longer periods for auditing and regulatory purposes.
