Table 11) Ef570 Technical Specifications - NetApp EF Series Feature Overview Manual

•
Dual Ethernet ports for management-related activities
•
Dual optical 16Gbps FC or 10Gbps iSCSI baseboard ports for host connection
•
SAS drive expansion ports to attach expansion-drive shelves
Note: Adding the new optional HICs for the EF570 controller provides faster host interfaces for iSCSI,
FC, and IB. See Controller Host Interface Features for the details of the new, faster host
interfaces.
Table 11 lists the technical specifications for the EF570-based storage systems.

Table 11) EF570 technical specifications.

Specification
Maximum raw system capacity (assumes
120 SSDs)
Maximum number of drives per system
(assumes not mixing shelf models)
Shelf form factor
Memory
Onboard host interface
Optional host interface (HIC) per controller
• Controllers must match
• A software feature pack* can be applied
to convert the FC onboard ports to iSCSI
or to convert between the three IB
protocols on the optional IB HIC
Drive shelves supported for expansion-
drive offerings
High-availability (HA) features
49 Introduction to NetApp EF570 All-Flash Arrays:
Feature Overview with SANtricity 11.50.2
EF570
1836TB (120 x 15.3TB SSDs)
120 SSDs maximum
2U, 24 drives
16GB or 64GB per controller; 64GB memory option required
when using NVMe/IB, NVMe/RoCE, or NVMe/FC protocols
32GB or 128GB per duplex system
2-port 10Gb iSCSI (optical) or 16Gb FC per controller
Note: Only one protocol can be configured per system using
the onboard host ports.
2-port 100Gb IB (iSER, SRP, NVMe/IB, or NVMe/RoCE based
on feature pack installed*)
Note: Onboard host ports are disabled when using NVMe
protocols.
4-port 12Gb SAS (wide-port); uses mini-SAS HD cables
4-port 32Gb FC or NVMe/FC (see Hardware Universe for SFP
details; 32Gb SFP supports 32Gbps and 16Gbps but not
8Gbps or slower)
Note: Onboard host ports are disabled when using NVMe
protocols
4-port 25Gb iSCSI (see Hardware Universe for SFP details;
must set port speed for 10Gbps or 25Gbps using SANtricity
System Manager; the 25Gbps SFP does work for 25Gb and
10Gb speeds, but the port does not change speeds
automatically)
DE224C (2U, 24 drives): 4 x SAS3 12Gbps expansion shelves
maximum
DE5600 (2U, 24 drives): 4 x expansion shelves max.
Note: Supports only SAS 2 (6Gbps) transfer speeds.
Dual active controllers with automated I/O path failover
