Figure 2) EF-Series 4KB random read performance improvements over time.
The EF570 is used for storage solutions that require the depth of enterprise-grade SAN storage and that
consistently deliver response times in the sub-120µsec range.
The array now supports the NVMe/FC protocol on the 32Gb FC host interface card in addition to
NVMe/IB and NVMe/RoCE.
Note: The NVMe/IB,NVMe/RoCE and NVMe/FC protocols are supported only on EF570 or E5700
controllers with the 64GB memory option running SANtricity 11.50 or later software versions
(11.50.2 for NVMe/FC).
This performance versatility is enhanced by multiple SSD choices to achieve the price-performance
combination that fits your business need. Current drive choices include:
• Entry-price-point 800GB SSDs for fast, small random workloads
• 1.6TB and 3.8TB fast, large-capacity SSDs to support higher-capacity sequential workloads, random
or mixed workloads
• 7.6TB and 15.3TB SSDs for fast, large-capacity requirements
EF-Series products have a documented history of delivering up to 99.9999% availability when systems
are properly sized, deployed, and maintained with NetApp support agreements. EF-Series also include
NetApp AutoSupport
®
technology to enhance your ongoing product experience.
Note: EF570 controllers are not offered in the 12-drive DE212C shelf or in the 60-drive DE460C shelf.
EF570 is offered only in the 24-drive DE224C shelf.
Each EF570 controller provides two Ethernet management ports for out-of-band management and has
two 12Gbps wide-port (x4 lanes) SAS drive expansion ports to support redundant drive expansion paths.
The EF570 also introduces new, faster host interface options that fit the needs of small and mid-tier
businesses or the world’s most demanding storage environments. These options are in one easy-to-
install and easy-to-maintain hardware and integrated management software package.
