Product Description
IBM 9009 ESNQ 571GB 15K RPM SAS SFF-2 4k Block Cached Disk Drive
The IBM ESNQ 571GB 15K RPM SAS SFF-2 4K Block Cached Disk Drive 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 15,000 RPM rotational speed for ultra-low-latency random I/O, 571 GB raw capacity, 12 Gb/s SAS connectivity, and native 4K/4224-byte sector format with integrated cache, making it ideal for high-transactional, database, ERP, and performance-critical IBM i applications requiring maximum IOPS and compatibility with modern 4K sector standards.
Product Description
The IBM ESNQ (feature code ESNQ, CCIN 5B47, part number 01LU584 or related variant) 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 15,000 RPM for exceptional 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 includes an integrated cache to optimize I/O performance under heavy workloads and 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/4096-byte sector format aligns with modern IBM i storage optimizations while ensuring compatibility with legacy environments. This drive is qualified for mission-critical IBM i environments on Power8, Power9, and select Power10 systems, offering superior reliability, power-loss protection circuitry, and firmware integration with AIX/IBM i releases.

Compatibility
The IBM ESNQ 571GB 15K 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 7.2+ (native SAS support, 7.4+ recommended for 4K optimizations), AIX 7.1+, Linux (RHEL/SUSE/Ubuntu), VIOS
- Attachment: Integrated SAS controllers/backplanes (#EJ0x, #EJ1x series) or external EXP24S/EXP24SX drawers (#5887/ESLS)
