Quick Answer: What socket does the A7158A 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). 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 A7158A ship?

Pro Disk Network dispatches the A7158A same-day on orders confirmed before 2 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.

Common Use Cases for A7158A

The A7158A 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.

New, Bulk, or Refurbished — Choosing Your Tier

Pro Disk Network offers the A7158A across three procurement tiers. Each tier is fully functional and warranted; the choice comes down to budget, warranty length, and whether the deployment is production-critical or capacity-expansion.

Frequently Asked Questions about A7158A

Is the A7158A a genuine HP part?
Yes. Pro Disk Network sources every A7158A as factory-original HP inventory verified against the manufacturer parts registry before listing. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned HP servers, surface-tested, and re-warranted by Pro Disk Network for 12 months.
What socket does the A7158A 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: CPUs & Processors

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 A7158A, 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).
