1 Introduction
NetApp EF570 arrays have a modern look, leverage the 12Gbps SAS, wide-port DE224C drive shelves,
and are managed by the secure, web-based SANtricity System Manager UI. Additionally, its performance
capabilities that enable new-age analytics and AI workloads to simply run faster.

In one powerful all-flash array package, the EF570 delivers optimal performance for both mixed random
workloads and large sequential workloads. The array can deliver consistent submillisecond-latency
response times for up to 1 million 4KB random read IOPS with as few as 24 solid-state drives (SSDs).
The same configuration can deliver up to 16GBps large sequential read throughput and about 8GBps
cache mirrored large sequential write throughput. When your workload meets the criteria of the built-in
full-stripe write acceleration feature, you can accelerate write performance up to 12Gbps. If you add an
expansion shelf and 12 additional SSDs, the EF570 array will deliver up to 21GBps throughput for large
sequential read workloads.
This performance capability builds on a legacy of generation-over-generation performance gains that EF-
Series all-flash arrays have delivered. Figure 2 shows the comparison between each generation of EF-
Series system and the associated SANtricity software release by comparing a 4KB random read
performance benchmark.
