Dell EMC VNX SAN – Product Analysis

This document is retired and no longer updated. Please see Dell EMC Unity for the most current product information. Updated March 27th, 2015 with end-of-year modifications. Analysis of EMC's VNX midrange product. This analysis covers the SAN (Block) capabilities.

The Dell EMC VNX has been replaced by Dell EMC Unity.

The Dell EMC VNX series of storage systems are a family of systems that provides unified file and block storage.    The  first  generation  of  VNX  replaced  the  CLARiiON  and  Celerra  product  line.    The  next generation of VNX systems contains a major update to the Storage Processor implementation for block storage.  The second generation VNX increased performance of VNX by 4X over the first generation and added additional capabilities.

The VNX systems provide a wide set of connectivity options for block access and for file access as a NAS system.  There are two different series in the VNX family:  the VNXe which is targeted as an entry level storage system and the VNX which is a mid-tier system.   VNX-F models are pre-configured all flash systems for customers wanting the performance characteristics of flash technology with the familiarity of the VNX systems.

The first generation VNX represented an evolution of the long available CLARiiON and Celerra products where the two systems were combined to provide a single, scalable storage system.  The CLARiiON has been a successful product line from Dell EMC resulting from the acquisition of Data General.   Multiple generations of the CLARiiON have been delivered. Dell EMC has now moved away from the CLARiiON name with incorporation of the successful Celerra NAS system into a combined product.

The second generation VNX optimized the Storage Processor to exploit the multiple core processors and multi-threading capability.
