Which two devices support the NetApp Remote Support Agent (RSA)?

The Service Processor (SP) is an embedded controller found in NetApp FAS and AFF systems that provides out-of-band management and supports the Remote Support Agent for system monitoring and remote access.

RTC (Real-Time Clock) is a hardware component for keeping time, not a management interface that supports software like RSA.

The Remote LAN Module (RLM) is an older out-of-band management interface, primarily found in earlier NetApp systems, which also supports the Remote Support Agent functionality.

ILO (Integrated Lights-Out) is Hewlett Packard Enterprise's proprietary embedded server management technology, not used in NetApp storage controllers.

BMC (Baseboard Management Controller) is a generic term for an embedded controller; while some NetApp products use a BMC, the question's context implies traditional NetApp controllers where SP or RLM are the specific interfaces that support RSA.
