IBM ES1G Enterprise 3.2 TB SSD PCIe4 NVMe U.2 module for AIX/Linux

The IBM ES1G Enterprise 3.2 TB SSD PCIe4 NVMe U.2 module for AIX/Linux (CCIN 59B9, part number 01LU968) is a high-performance, enterprise-class NVMe solid-state drive optimized for AIX and Linux workloads on IBM Power Systems servers. This 3.2 TB U.2 (2.5-inch) PCIe Gen4 x4 NVMe SSD delivers ultra-low latency, massive IOPS, and high endurance in a hot-plug U.2 form factor, making it ideal for boot drives, large-scale database acceleration, virtualization, high-concurrency ERP, analytics, AI inference, and mixed-use enterprise applications requiring substantial capacity and fast internal flash storage.

Product Description

The IBM ES1G (feature code ES1G, CCIN 59B9, part number 01LU968) is an enterprise 3.2 TB NVMe U.2 SSD module designed for direct attachment in Power Systems servers supporting PCIe Gen4 U.2 bays (primarily Power10 and select Power9 G-models with U.2 backplanes). It provides 3.2 TB of enterprise-grade NAND flash storage with PCIe Gen4 x4 interface for high-bandwidth, sub-100 μs latency access. The drive supports native AIX and Linux attachment (no VIOS required in many configurations), software RAID/mirroring via AIX LVM or Linux mdadm, and advanced features including power-loss protection capacitors, end-to-end data protection (T10 DIF/DIX), and high endurance for mixed-read/write operations. It is fully qualified for mission-critical AIX and Linux deployments on Power10 (e.g., S1022/S1024) and Power9 models with U.2 support, offering dramatically higher IOPS and throughput than SAS SSDs while maintaining enterprise reliability and firmware alignment.

Features

3.2 TB enterprise-class usable capacity in U.2 (2.5-inch) form factor.
PCIe Gen4 x4 NVMe interface for high-bandwidth, ultra-low-latency performance.
High endurance (typically 1–3 DWPD over 5 years, mixed workload).
Power-loss protection circuitry to safeguard data during power events.
Hot-plug U.2 carrier for zero-downtime maintenance in supported bays.
Native AIX/Linux support with sector format compatibility (512e/4Kn).
Advanced error correction, wear-leveling, and T10 DIF/DIX end-to-end protection.
LED status indicators for activity, fault, and health.
Full IBM qualification for Power10/Power9 U.2 backplanes.
