Confirm the socket against your motherboard's CPU support list - Intel Xeon Scalable spans LGA 3647 (1st/2nd gen), LGA 4189 (3rd gen Ice Lake), and LGA 4677 (4th/5th gen Sapphire/Emerald Rapids). A BIOS update is often required for newer steppings even on the same socket. Email sales@prodisknetwork.com with your motherboard model for a compatibility check.
How fast does the 501-6370 ship?
Pro Disk Network dispatches the 501-6370 same-day on orders confirmed before 3 pm ET. Multi-pallet projects requiring crating ship within 2 business days. International shipping (Canada, Mexico, EU, APAC) takes 3-7 business days via DHL Express or FedEx International Priority.
The 501-6370 is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.
Citrix VDI Pool — Frequency-sensitive — prefer high-clock 16–18 core SKUs over high-core-count parts to maintain user-perceived snappiness.
Kubernetes / Tanzu Workers — Higher core count amortises better across many small Pods. EVC mode planning matters for live-migrate parity.
AI Inference Host — Sapphire Rapids and Emerald Rapids include AMX silicon for INT8 inference acceleration — meaningful uplift for BERT, ResNet, and LLM serving.
What is the 501-6370?
The 501-6370 is a Sun server-class processor with clock speed 1.28 GHz, manufactured by Sun. Pro Disk Network ships this part new and certified-refurbished from our US warehouse with same-day dispatch on orders placed before 3 PM ET, backed by a 30-day return guarantee.
Pros & Cons of 501-6370
Pros
Lower cost than the manufacturer channel for refresh cycles
Matched-pair option for dual-socket consistency
Sequential serial numbers on bulk orders for cluster builds
Cons
Older microarchitecture — not appropriate for new AI/AMX workloads
Not always silicon-binned for overclocking
Stepping mismatch with newer revisions can require microcode update
Frequently Asked Questions about 501-6370
Is the 501-6370 a genuine Sun part?
Yes. Pro Disk Network sources every 501-6370 as factory-original Sun inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned Sun servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
What socket does the 501-6370 use?
Confirm the socket against your motherboard's CPU support list - Intel Xeon Scalable spans LGA 3647 (1st/2nd gen), LGA 4189 (3rd gen Ice Lake), and LGA 4677 (4th/5th gen Sapphire/Emerald Rapids).

Pro Disk Network Buyer’s Guide: Processor Boards
Socket Compatibility, EVC Mode, and BIOS Revision Planning
For Hyper-V clusters, Live Migration compatibility is more forgiving but still benefits from matched CPU stepping across cluster nodes. For Kubernetes / Tanzu, CPU heterogeneity is acceptable because pods are stateless, but resource-request planning becomes harder when nodes have different core counts.
AI Workloads, AMX, and the Inference Performance Story
Late-generation Intel Xeon processors (Sapphire Rapids, Emerald Rapids, Granite Rapids) include AMX (Advanced Matrix Extensions) silicon that accelerates INT8 inference workloads dramatically. For the 501-6370, if AMX is present, BERT-base inference throughput improves 4-6× over the previous generation; LLM inference (Llama 2 7B INT8 quantised) improves 2-3×. AMX does not require code changes when used through libraries that already support it (oneAPI, ONNX Runtime, OpenVINO).
