350-601 Compute Practice Question
A UCS B-series blade is configured to boot from SAN using a vHBA that connects to a Fibre Channel SAN. The storage administrator reports that the LUN is not being presented to the blade. Which component in the UCS domain is responsible for mapping the vHBA WWPN to the physical Fibre Channel interface?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Fabric Interconnect
In UCS, the Fabric Interconnect (FI) acts as a Fibre Channel forwarder (FCF) or NPV switch. The vHBA's WWPN is assigned by UCS Manager and the FI maps it to the appropriate uplink Fibre Channel interface. The UCS Manager itself configures this mapping, but the actual mapping occurs on the FI.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IOM (FEX)
Why it's wrong here
IOM aggregates traffic but does not handle Fibre Channel mapping.
- ✗
CIMC
Why it's wrong here
CIMC manages rack servers, not UCS B-series blade mapping.
- ✓
Fabric Interconnect
Why this is correct
The FI maps the vHBA WWPN to the physical Fibre Channel interface.
- ✗
UCS Manager
Why it's wrong here
UCS Manager configures the mapping but the FI performs the mapping.
