Sun Oracle 7317636 / 7346982 System Board Specifications

1. Overview

The Oracle 7317636 (with alternative/substitute engineering part numbers like 7346982) is the enterprise-class dual-socket system board designed specifically for the Oracle Server X8-2 (1U architecture) and compatible Exadata X8-2 database nodes. Engineered for dense high-performance computing, it leverages Intel’s Second-Generation Xeon Scalable processor platform to deliver robust memory bandwidth, mission-critical reliability, availability, and serviceability (RAS).

2. Technical Specifications

Processor / CPU Architecture

• Socket Type: Dual FCLGA3647 (Socket P)

• Supported Processors: 1 or 2 Intel® Xeon® Scalable Processors (Second Generation / Cascade Lake-SP)

• Max Core Count: Up to 24 cores per processor socket (48 cores total per system)

• Thermal Design Power (TDP): Supports high-performance SKUs up to 165W–205W (e.g., Intel Xeon Platinum 8268 / 8260)

Memory Architecture

• DIMM Slots: 24 DDR4 memory slots (12 DIMMs per CPU socket / 6 memory channels per CPU, 2 DIMMs per channel)

• Memory Type Supported: DDR4 Registered DIMMs (RDIMM) or Load Reduced DIMMs (LRDIMM)

• Speed: Up to 2666 MHz / 2933 MHz (depending on the installed processor capability)

• Maximum Capacity:

  • Up to 1.5 TB using 64GB LRDIMMs

• Error Correction: Advanced ECC, Memory Mirroring, and Lockstep Mode options configured via BIOS.

 Expansion & I/O Interfaces

• PCI Express Slots (Via Riser Card Interface): Supports up to four PCIe 3.0 slots:

  • Two x16 PCIe 3.0 slots

  • Two x8 PCIe 3.0 slots (one slot is generally reserved internally for the dedicated SAS HBA controller)

• Storage Onboard Interfaces:

  • Integrated dual M.2 boot drive sockets (supports 2x SATA M.2 flash SSDs for OS mirroring)

  • High-density NVMe/SAS signal connector arrays routing straight to the front hot-swappable drive backplane.

 Networking & Management Ports

• Primary LAN: Built-in flexible network options depending on the chosen physical tail-piece configuration:

  • 2x 10GbE copper ports (RJ45) OR 2x 10/25GbE SFP28 ports

• Server Management:

  • 1x Dedicated 10/100/1000 Base-T Network Management Port (NET MGT RJ-45)

  • 1x Serial Console Management Port (SER MGT RJ-45)

• USB Connectivity: 2x USB 3.0 ports (1x rear external, 1x internal Type-A port for secure embedded boot keys).

Remote System Management & Firmware

• Onboard Management Processor: Oracle Integrated Lights Out Manager (ILOM) version 4.x or 5.x base

• Management Features: Full remote KVM, IPMI 2.0 compliance, secure Redfish API, comprehensive hardware fault isolation telemetry, and real-time power/thermal monitoring.

• System BIOS: Oracle Unified Extensible Firmware Interface (UEFI) with advanced security boot options.

3. Part Number Cross-Reference Matrix

When tracking down inventory or performing field replacements (FRU), this system board is identified under several Oracle replacement numbers:

Oracle Marketing Part No.	Oracle Manufacturing / Bare Board PN	Targeted System	Components Included
7317636	7346982 (Main PCBA)	Oracle Server X8-2 / Exadata X8-2	Motherboard unit only (Sockets protected)

4. Key Deployment Notes for Enterprise IT Refurbishers

• Chassis Alignment: This motherboard uses Oracle’s custom mounting alignment layout featuring quick-release green captive alignment levers. It matches a 1U chassis form factor and will not fit standard ATX/EEB rack enclosures.

• CPU Sockets: Uses the standard FCLGA3647 socket architecture. When installing or swapping CPUs, always utilize the correct Intel assembly carrier bracket to prevent damaging the fine socket array pins.

• Minimum Boot Requirement: The board requires at least 1 CPU installed alongside a minimum of 1 DIMM populated on Channel 0 for that specific CPU socket to post. Maximum I/O performance and full utilization of all PCIe slots require both sockets to be populated.
