EF-Series all-flash arrays: Microsecond response for your demanding applications

When you need to supercharge performance-sensitive workloads like real-time analytics, HPC, and databases, the price-to-performance benefit of NetApp® EF-Series all-flash arrays speaks volumes. They deliver microsecond response to your most demanding apps, maximum uptime, and six-nines reliability.

Why NetApp EF-Series arrays?

Say hello to faster, more actionable results

Big data analytics. High-performance computing. Demanding databases. NetApp EF-Series all-flash arrays are built for today’s giant workloads (and the even bigger ones to come).

EF-Series arrays combine impressive IOPS, microsecond response times, and incredible throughput capacity, so your most demanding apps never miss a beat. In addition, the EF-Series is powered by NetApp® SANtricity software to give you extensive configuration flexibility, custom performance tuning, and complete control over data placement. In other words, a trifecta of data management brilliance.
