The HPE Synergy Master/Satellite architecture is strictly defined by the compatibility between the " Master " (Primary) interconnect modules and the " Satellite " (Interconnect Link Modules - ILM) modules across multiple frames.

Fabric Generations: HPE Synergy fabrics are categorized into generations. The HPE Virtual Connect SE 100Gb F32 Module is a second-generation (Gen2) " Master " module. It is designed to work with the HPE Synergy 50Gb Interconnect Link Module as its satellite to extend the fabric to additional frames.

ILM Compatibility (The 20Gb vs 50Gb Issue): The 20Gb Interconnect Link Modules mentioned in the proposed new frame are first-generation (Gen1) satellite modules. They were designed to work with the HPE Virtual Connect SE 40Gb F8 Module (Gen1 Master).

According to HPE Synergy cabling and fabric rules, you cannot mix Gen1 satellites (20Gb ILM) with Gen2 masters (100Gb F32).

For the 100Gb F32 Master modules in Frame 1 to extend the Ethernet/FCoE fabric to Frame 2, Frame 2 must use the 50Gb Interconnect Link Modules .

Fibre Channel Connectivity: Unlike the Ethernet fabric, the HPE Synergy Virtual Connect SE 32Gb FC Modules are not master/satellite modules. They are standalone SAN interconnects. Each frame that requires native Fibre Channel connectivity typically contains its own pair of FC modules. They are managed within the same Logical Enclosure in HPE OneView, but they do not use " Interconnect Link Modules " or " stacking " in the way Ethernet masters do.

Why other options are incorrect:

Option A: There is no requirement to " balance " the number of compute modules across frames (12 in one, 8 in another) for a Logical Enclosure to function.

Option C: HPE OneView licensing for Synergy is per-node/per-frame (OneView Advanced). There is no specific " Extended Logical Enclosure " license required to add a second frame to an existing LE; the management infrastructure simply scales as frames are added.

Option D: " Stacking " is a term often used for traditional switches. In Synergy, the 32Gb FC modules provide individual uplinks to the SAN fabric. While they are part of the same logical management entity, the term " stacked " is technically inaccurate for how these modules are interconnected or managed across frames in this specific architecture.
