Which three factors should you consider before you install an E2860 in a data center? (Choose three.)
Current Draw: It is important to consider the electrical current draw of the E2860 to ensure that the data center power infrastructure can support it without overloading circuits.
Heat Dissipation: The heat generated by the E2860 needs to be accounted for in the data center's cooling design. Proper heat dissipation mechanisms must be in place to prevent overheating.
Ambient Temperatures: The operating environment's temperature should be within the specified range for the E2860 to function correctly and reliably. Ensuring that the ambient temperatures are controlled is crucial for optimal performance and longevity of the equipment.

What does the CHAP secret accomplish for an E-Series system?
CHAP (Challenge Handshake Authentication Protocol): CHAP is a protocol used to authenticate the identity of an initiator or target in iSCSI communications. This ensures that only authorized devices can connect to the storage array over the iSCSI network.
Implementation in E-Series: In the context of E-Series systems, CHAP secrets are configured to provide an additional layer of security by requiring both the initiator and target to authenticate each other using a shared secret before establishing an iSCSI session.

An E2812 system, without expansion shelves, is configured with 12 Gb SAS host interface cards (HICs) and is directly connected to a host. However, the host cannot access the volumes.
In this scenario, which two troubleshooting steps should you take? (Choose two.)
Verify that the E2812 host port SAS link up lights are illuminated
The link up lights on the E2812 host port should be checked to confirm that the physical layer connection is established. If the lights are not illuminated, it indicates that there is no physical link between the host and the E2812 system, which would explain why the host cannot access the volumes.
Verify that the correct SAS ports are in use on the E2812 system
Ensuring the correct SAS ports are used is critical. Using incorrect ports might result in connectivity issues. The documentation for the E2812 provides guidance on the appropriate ports to be used for direct connections to a host.

A customer's host is running a Red Hat Enterprise Linux 7.6 server with dm-mp configured for ALUA and is connected to a single volume on the EF280 system that is shown in the exhibit.
In this scenario, how many active/optimized paths are available to the volume?
Based on the exhibit provided and the scenario where a Red Hat Enterprise Linux 7.6 server is configured with Device Mapper Multipathing (dm-mp) for Asymmetric Logical Unit Access (ALUA) and connected to a single volume on the EF280 system, there are 4 active/optimized paths available to the volume.
In ALUA configurations, paths are classified as active/optimized or active/non-optimized. Each controller on the EF280 system will have two active/optimized paths to the volume, leading to a total of four such paths. This setup ensures high availability and optimal performance for data access.

=========================
The NetApp E-Series system with a 32 Gb FC Host Interface Card (HIC) requires which type of fiber cable to connect to switches or to connect directly to hosts extending up to 100 meters?
OM4
OM4 fiber optic cables are recommended for 32 Gb FC connections up to 100 meters due to their high bandwidth capabilities and lower attenuation, ensuring optimal performance for such high-speed connections.
