The NetApp E2812 is an E-Series storage system. When ordered as a "Duplex" system, it includes two controllers for high availability. Each E2800 series controller module is equipped with two onboard host interface ports. The question specifies the system is a "10 GbE Base-T" model, which defines the type of these onboard ports. Therefore, with two controllers, each having two 10GbE Base-T ports, the total maximum number of available ports is four (2 controllers × 2 ports/controller). The exhibit visually confirms the layout of a duplex controller shelf with two host ports per controller.

A. 8: This would incorrectly assume four onboard 10GbE Base-T ports per controller, which is not a standard E2800 configuration.

C. 6: This number does not align with the symmetric design of E2800 duplex controllers, which have two ports each.

D. 12: This number is incorrect and might be confused with the number of drive slots in the E2812 chassis, not the host port count.

Section: "E2800 controller features"

Content: This section states

"Each E2800 controller includes two host ports." The accompanying diagrams of the controller rear panel clearly show two host ports

which can be configured for various protocols

including 10Gb iSCSI (Base-T).

E2800 Controller Specifications.

Section: "Controller Specifications" for E2800.

Content: The official specifications list "Onboard host ports" as "2 per controller." It details the available protocols for these ports

including "10-Gbps iSCSI (SFP+ or Base-T)." For a duplex system

this confirms a total of four ports.
