The Nexsan E48VT is an ultra-reliable, high-density, high performance, efficient storage array that enables lower storage costs, maximum storage uptime, and data storage ROI boosts for your organization. E-Series V systems consume less than one-third of the power in one-third of the rack space of typical arrays, with up to 240 terabytes of capacity in just 4U and now offers 400% more memory and 50% increased CPU speed over the E-Series.

The E-Series V is offered in three core configurations: E60VT (360 TB in 4U), E48VT (288 TB in 4U), and E18V (108 TB in 2U). Each can be easily expanded with additional capacity by adding the corresponding expansion unit: E60XV, E48XV, or E18XV.

E-Series V Key Benefits

Optimize Your Capacity Needs Now & Expand in the Future

The E-Series V storage arrays and expansion units offer mid-size organizations affordable enterprise-level Fibre Channel, SAS and/or iSCSI SAN storage used for a variety of capacity-optimized and performance-driven applications.

For larger organizations, E-Series V is a versatile SAN or DAS solution to stay ahead of the enormous data growth, demanding workloads, and high resiliency requirements in media & entertainment, government, healthcare, HPC, financial, surveillance and service provider sectors.

Turbocharge Your Performance for Ultra-Fast Write Speed

E-Series V features an advanced active/active controller design, including use of a dedicated hardware engine, or “turbocharger”, which accelerates RAID parity generation and doubles the sequential write performance over the prior version of E-Series. The turbocharged E-Series V is ideal for back-up and recovery applications and continuous data streaming bulk storage applications.

Achieve More Efficiency in Higher Density Than Typical Arrays

Organizations deploying E-Series V san storage arrays can mix and match capacity-optimized HDDs and performance-optimized HDDs and SSDs to meet performance and capacity needs. E-Series V arrays consume less than one-third of the power in one-third of the rack space of typical arrays, with up to 360 terabytes of capacity in just one 4U, and up to a total of 1080 TB in a fully-scaled, 12U configuration.

With E-Series V systems, you can engage Nexsan AutoMAID® disk management capabilities to reduce power consumption by up to 87%, lowering operating expenses and extending the overall life of the system.

Ensure Your Data Is Protected with Qualified, Reliable Design

The E-Series V storage array exceeds the most stringent reliability demands, leveraging an innovative hardware design including Cool Drive TechnologyTM and anti-vibration design that significantly reduces heat and vibration while improving system reliability and performance. The reliability of E-Series V is qualified through extensive stress testing before shipment. Array-based snaps and asynchronous replication extend E-Series V data protection capabilities.

Access Your Data Continuously

The E-Series V features multipathing support and dual redundant, hot-swappable active components. As an administrator, you will receive SNMP alerts or email notifications of component failures. Upon drive failure, a spare drive is automatically rebuilt into the RAID set for complete business continuity.

With up to 16GB of battery-backed and flash-protected cache per controller, the E-Series V solution mirrors cache between controllers in a dual controller configuration. Active Drawer TechnologyTM overcomes the challenges of competitive arrays by allowing a technician to service a drawer of drives easily while keeping your data available.
