IBM 8284 21A S812 iSeries Power 8 Servers

IBM 8284-21A S812 Power8 System

The IBM Power S812 (8284-21A) is a compact 2U rack-mount server from the POWER8 family, optimized for IBM i workloads in small to medium business environments. This single-socket system features a 4-core POWER8 processor (typically EPX0 or EPX5 feature code), delivering solid CPW performance for reliable enterprise applications with low space and power requirements. It includes 32 GB DDR3 memory (scalable up to 512 GB), 600 GB SAS HDD (2 × 300 GB 15K RPM SFF-3 drives) with RAID support, a 2-port 10/1 GbE BaseT RJ45 Ethernet adapter, DVD-RAM drive, and all necessary components for rack deployment. The server runs natively on IBM i (no VIOS required in lower-tier configs), supports PowerVM virtualization (limited by tier), and is ideal for cost-effective IBM i hosting, light virtualization, or departmental workloads.

Key Features

  • Processor: 4-core POWER8 (single socket; EPX0 / EPX5 typical at 4.0–4.15 GHz).
  • Performance: Approximately 38,000–45,000 CPW (P10 tier; interactive capacity varies by config).
  • Memory: 32 GB DDR3 base (scalable to 512 GB with 16 DIMM slots).
  • Storage: 600 GB (2 × 300 GB 15K RPM SAS SFF-3) with RAID-5/6/10 support.
  • Connectivity: 2-port 10/1 GbE BaseT RJ45 Ethernet adapter.
  • Media: DVD-RAM drive included.
  • Form Factor: 2U rack-mount (compact, space-efficient).
  • Software: Native IBM i support (7.1–7.4); PowerVM virtualization available.
  • Reliability: Redundant hot-swap power/cooling options, EnergyScale efficiency.

This 2U configuration is tailored for space-constrained data centers or branch offices running IBM i with moderate workloads. It supports memory and storage expansions but has fewer PCIe slots than 2U/4U models.

Compatibilities

The IBM Power S812 8284-21A is compatible with:

  • IBM i operating system (7.1–7.4; native execution).
  • PowerVM for virtualization (limited in lower tiers).
  • IBM Power Systems storage and peripherals via SAS/SFF-3 bays and PCIe Gen3.
  • Ethernet networks and standard adapters for connectivity.
  • Backward compatibility with IBM i applications and data from prior Power generations.
  • Enterprise workloads in small to medium setups, with support for data-intensive tasks on AIX/Linux as well.

Depend on this compact POWER8 server for efficient, space-saving IBM i performance in rack environments with proven reliability.
