⚡ GPU vs Standard — Key Differences

Dimension	Standard (Compute/Storage)	GPU
BO Lead Time	4 weeks target	7-8 weeks
Production CT (QBR)	P50≤8d, P90≤11d	P50≤12d, P90≤15d (+4d)
BO CT (QBR)	P50≤22d, P90≤29d	P50≤29d, P90≤36d (+7d)
PIDs per BO-line	~1-5	~28 (dedup critical)
DC ETA Auto-Set	On Reserved/Locked	Immediately on allocation
Factory Lines	Air-cooled standard	Liquid-cooled distinct lines
CT SLA Program	28d stretch / 35d standard	Separate GPU timeline
PFAM Filter	Standard patterns	%GPU_COMPUTE-GB% (not %GB%)
FG Date Column	FinishedGoodsETADate (partial)	ProductionETADate (FG* = 0%)
Delivery	Standard truck	White glove for GB300/Callan

🔥 GPU PFAM Identification

GPU patterns: %GPU%, %ND-%, %HPC%
GB GPU filter: Use %GPU_COMPUTE-GB% NOT %GB% (catches Delta CDUs)
Cooling/Liquid PFAMs: AZURE_COOLING_LIQUID1* = Delta CDUs (non-managed SI, excluded from dashboards)
Ingrasys liquid cooling: Uses L10-* prefix for liquid cooling operations
Delta: CDU manufacturer, ~10K racks/qtr FY26, DELTA-TW/TX factories

📈 GPU QBR Scoring Thresholds

KPI	5 (Best)	4	3	2	1 (Worst)
Production CT	P50≤12d P90≤15d	≤14d/17d	≤16d/19d	≤18d/21d	>18d/21d
BO CT	P50≤29d P90≤36d	≤32d/39d	≤35d/42d	≤38d/45d	>38d/45d

⚠️ GPU Anti-Patterns & Critical Rules

NEVER DO

Use BO-line grain for GPU rack counts (97% undercount)
Use FinishedGoodsETADate for GPU (0% populated)
Filter %GB% instead of %GPU_COMPUTE-GB%
Mix GPU into standard CT headline P50/P90
Use averages for cycle time (always P50/P90)

ALWAYS DO

Dedup BOR to PID grain (ProductionId) for rack counts
Use ProductionETADate / ProductionCompleteDate
Separate GPU and Standard CT thresholds
Break out liquid-cooled vs air-cooled factory capacity
Apply all 3 CT population filters (ScheduleLineType + LifecycleStatus + OrderLineStatus)

GPU-SPECIFIC FLOWS

White glove delivery for GB300/Callan (ATC last-mile)
Liquid cooling lines = distinct factory bottleneck
Insurance coverage for GPU components at Arrow
Reserved immediately on allocation (no horizon wait)
~28 PIDs per BO-line (PID = 1 rack)
