IBM 9105 42A S1024 pSeries Power 10 Servers

The IBM Power S1024 (9105-42A) is a powerful 4U rack-mounted scale-out server powered by IBM Power10 processors. This two-socket system delivers high performance, massive scalability, and advanced security for demanding AIX, IBM i (virtualized), and Linux workloads. It features up to 48 cores, 8 TB DDR4 memory, extensive NVMe storage, Gen5 PCIe connectivity, transparent memory encryption, in-core AI acceleration via Matrix Math Accelerator (MMA), and PowerVM virtualization. With high density, energy efficiency, and hybrid cloud support, it excels in mission-critical enterprise applications, data-intensive processing, and consolidated environments.

Key Features

• Dual-socket Power10 processor support for up to 48 cores and 384 threads.
• Transparent memory encryption with no performance overhead.
• In-core AI inferencing and ML acceleration with MMA.
• Up to 8 U.2 NVMe bays for high-speed internal storage; expansion drawer support.
• PCIe Gen5 slots (concurrently maintainable) for high-bandwidth adapters.
• PowerVM Enterprise Edition for virtualization and hybrid cloud flexibility.
• Redundant hot-swap power supplies, fans, and components for high availability.
• Capacity Upgrade on Demand for cores and optional features.
• Supports IBM i partitions (max 4 cores each, requires VIOS), AIX, Linux (including Red Hat OpenShift).

Technical Specifications

• Form Factor: 4U rack-mounted (19-inch rack).
• Processors: Dual-chip Power10 modules (same model required in both sockets):
  • EPGM: 12-core 3.4–4.0 GHz (scalable activations).
  • EPGC: 16-core 3.1–4.0 GHz.
  • EPGD: 24-core 2.75–3.90 GHz.
  • Up to 48 activated cores total.
• Memory: Up to 8 TB DDR4 (32 DDIMM slots; 16 usable with one socket); DDR5 support in some configs (higher bandwidth).
• Storage: Up to 8 x U.2 NVMe bays (max ~51.2 TB internal flash); optional SAS/NVMe expansion drawers (e.g., EXP24SX withdrawn, NED24/ESLS).
• PCIe Slots: Multiple Gen5/Gen4 slots (configuration-dependent; high bandwidth for adapters).
• Connectivity: Onboard options; optional Ethernet (10/25/100 Gb), Fibre Channel (32/64 Gb), SAS.
• Power/Cooling: Redundant hot-swap supplies (e.g., 1600W/2000W); efficient design.
• Other: Supports Capacity on Demand; Light Path diagnostics.

Available Configurations

Common processor-based examples (often refurbished/used; prices vary by vendor):

• IBM 9105-42A S1024 with EPGD 24-Core Processor: Higher core density for demanding workloads.

Memory, storage, and I/O adapters configured via IBM feature codes at order time. Supports core activations and Capacity on Demand upgrades.

Compatibility

• Operating Systems: IBM i (virtualized LPARs max 4 cores each, requires VIOS), AIX, Linux (including Red Hat OpenShift).
• Virtualization: PowerVM Enterprise Edition; supports multiple IBM i partitions alongside AIX/Linux.
• Expansion: PCIe I/O drawers; SAS/NVMe expansion drawers for additional storage/slots.
• Environments: Suited for enterprise consolidation, data centers, hybrid cloud; integrates with Power Private Cloud models.
• Security: Transparent memory encryption, hardware-accelerated features, quantum-safe readiness.
• No intermixing with incompatible older generations.
