NetApp commissioned Demartek to evaluate the performance of its EF540 flash array and the E-Series SANtricity SSD Cache technology. The NetApp EF540 flash array running the SANtricity operating system is designed for performance-driven applications with sub millisecond latency requirements. The NetApp E5400 also running the SANtricity operating system is a performance-efficient midrange storage array for a variety of application-driven environments.
The EF540 system testing was performed with 24 800GB SSDs. The E-Series SSD Cache testing was done on an E5460 system with 20 NL-SAS drives and a single 800GB SSD.
Demartek’s findings concluded that the NetApp EF540 all-flash enterprise storage system provides a compact solution to meet demanding requirements.
The EF540 in the all-flash configuration achieved greater than 330,000 IOPS while maintaining response times of less than 1 millisecond.
The EF540 can scale up to nearly 40TB of all-flash capacity in 4 rack-units (4U).
The NetApp E5460 with SANtricity SSD cache provides strong read performance acceleration while leveraging lower-cost HDDs for capacity.
The E5460 SANtricity SSD Cache achieved almost 17x better IOPS and bandwidth performance, and greater than 17x lower (better) latency after the cache was warmed.
The E5460 SANtricity SSD Cache can be enabled with a single SSD and can grow with additional SSDs as needed.
In summary, Demartek concluded that the NetApp EF-Series and E-Series are well suited to meet many workload environment requirements. EF540 provides outstanding results for performance-driven applications demanding high IOPS and low latency and the E-Series SANtricity SSD Cache feature is ideal to increase application performance for read-intensive applications.
