IBM ESEU 571GB 10K RPM SAS SFF-2 Disk Drive 4K Block - 4224

The IBM ESEU 571GB 10K RPM SAS SFF-2 Disk Drive (4K block / 4224 sector) is a high-performance enterprise SAS hard disk drive optimized for IBM i workloads on Power Systems servers. This 2.5-inch SFF-2 drive delivers 10,000 RPM rotational speed for low-latency random I/O, 571 GB raw capacity, 12 Gb/s SAS connectivity, and native 4K/4224-byte sector format, making it ideal for transactional, database, ERP, and mixed-workload IBM i applications requiring high throughput and compatibility with legacy 528-byte sector expectations.

Product Description

The IBM ESEU (feature code ESEU, part number typically 00E9935 or related variant, CCIN often 59D2 or similar) is a 2.5-inch Small Form Factor (SFF-2) SAS hard disk drive designed specifically for IBM Power Systems running IBM i (iSeries/AS/400). It operates at 10,000 RPM for superior random read/write performance, with a 571 GB native capacity and 12 Gb/s SAS interface for high-bandwidth attachment to integrated controllers or SAS adapters. The drive uses a standard SFF-2 hot-plug carrier compatible with internal Power Systems bays and EXP24S/EXP24SX expansion drawers. It supports IBM i native attachment (no VIOS required in many configurations), OS mirroring, RAID 0/1/5/6/10 via the host controller, and end-to-end data protection (T10 DIF/DIX). The 4K/4224-byte sector format ensures compatibility with IBM i's advanced sector size support while maintaining backward compatibility with traditional 528-byte expectations. This drive is qualified for mission-critical IBM i environments on Power8, Power9, and select Power10 systems, offering proven reliability, power-loss protection circuitry, and firmware alignment with AIX/IBM i releases.

Compatibility

The IBM ESEU 571GB 10K RPM SAS SFF-2 Disk Drive is compatible with:

Power Systems Models:
- Power8: S814 (8286-41A), S822/S824 (8284-22A), E870/E880 (9119-MME/MHE), and others
- Power9: S914 (9009-41A/41G), S922 (9009-22A/22G), S924 (9009-42A), E950/E980, and related models
- Power10: Select scale-out models with SAS support (internal bays or EXP24SX/EXP24S drawers)
Operating Systems: IBM i 7.1+ (native SAS support, 7.4+ recommended for 4K/4224 optimizations), AIX 7.1+, Linux (RHEL/SUSE/Ubuntu), VIOS
Attachment: Integrated SAS controllers/backplanes (#EJ0x, #EJ1x series) or external EXP24S/EXP24SX drawers (#5887/ESLS)
RAID Support: Managed by host server (integrated RAID or VIOS)
Limitations: Not compatible with NVMe backplanes; 12 Gb/s SAS requires compatible adapters/controllers; SFF-2 carrier may require specific backplane support (not all Power10 use SFF-2)

Verify exact backplane requirements, firmware levels, and IBM i TR levels via IBM Sales Manual or resources for your specific Power Systems model.
