Mikhail Chusavitin 1eb639e6bf redfish: skip NVMe bay probe for non-storage chassis types (Module/Component/Zone) 
On Supermicro HGX systems (SYS-A21GE-NBRT) ~35 sub-chassis (GPU, NVSwitch,
PCIeRetimer, ERoT/IRoT, BMC, FPGA) all carry ChassisType=Module/Component/Zone
and expose empty /Drives collections. shouldAdaptiveNVMeProbe returned true for
all of them, triggering 35 × 384 = 13 440 HTTP requests → ~22 min wasted per
collection (more than half of total 35 min collection time).

Fix: chassisTypeCanHaveNVMe returns false for Module, Component, Zone. The
candidate selection loop in collectRawRedfishTree now checks the parent chassis
doc before adding a /Drives path to the probe list. Enclosure (NVMe backplane),
RackMount, and unknown types are unaffected.

Tests:
- TestChassisTypeCanHaveNVMe: table-driven, covers excluded and storage-capable types
- TestNVMePostProbeSkipsNonStorageChassis: topology integration, GPU chassis +
  backplane with empty /Drives → exactly 1 candidate selected (backplane only)

Test Server Collection Memory

Keep this table updated after each test-server run.

Definition:

  • Collection Time = total Redfish collection duration from collect.log.
  • Speed = Documents / seconds.
  • Metrics Collected = sum of Counts fields (cpus + memory + storage + pcie + gpus + nics + psus + firmware).
  • n/a means the log does not contain enough timestamp metadata to calculate duration/speed.

Server Model: SYS-A21GE-NBRT (Supermicro HGX B200)

HGX note: this model has ~40 sub-chassis (GPU, NVSwitch, PCIeRetimer, ERoT/IRoT, BMC, FPGA) all exposing empty /Drives collections. Post-probe NVMe must skip ChassisType=Module/Component/Zone or it probes 35 × 384 = 13 440 URLs → ~22 min wasted. Fixed in the commit that added chassisTypeCanHaveNVMe (2026-03-12). Expected post-probe NVMe time after fix: <5s.
