Dell and Nexenta: Storage Solutions
 
Nexenta and Dell Team Up to Deliver Massively Flexible & Scalable Storage
 
Dell and Nexenta

What is NexentaStor?

NexentaStor is a unified storage management platform that delivers enterprise-class features and runs on industry-standard hardware. With NexentaStor, customers can save 70-80% over proprietary solutions while also enjoying superior functionality and flexibility.

   

Why Dell? Why Nexenta?

Dell offers world-class hardware platforms and the enterprise-class support Nexenta's customers demand.

Nexenta is the industry's only storage vendor truly delivering on the message of Software-defined Storage (SdS). With more than 5,000 customers and more than 50,000 deployments to date — including four of NetApps top 10 customers, Nexenta has been named the fastest growing storage company ever. Nexenta's flagship product, NexentaStor, helps organizations implement high-perfomance yet cost-effective data storage solutions by taking advantage of features such as inline deduplication, unlimited snapshots and cloning, hardware-agnostic solutions, and high availability support.

 
 
Case Study: VMword 2011
Storage for Hands-on Lab
 
 

Nexenta, EMC, and NetApp provided storage for the labs; Nexenta hosted more than 50% of the total lab workload at performance matching EMC and NetApp.

Other Nexenta products — like NexentaStor Plug-ins to enable an NFS global Namespace or archive data to an Amazon, Google, or OpenStack cloud — and the recently released NexentaVSA for View — co-developed with VMware for simplicity and calibration of VDI deployments — are evidence of Nexenta's commitment to use its software model to address the real needs of its enterprise-class customers.

Nexenta and Dell: Storage Solutions
