Product Description
The IBM ESBK 1.55TB Enterprise SAS 4k SFF-3 SSD (Feature Code: ESBK) is a high-performance 2.5-inch solid-state drive designed for IBM Power Systems running IBM i. With a 6 Gbps SAS interface, 1.55TB capacity formatted with 4224-byte sectors, and CCIN 5B45, it features a 256MB DRAM cache and eMLC4 technology for 10 drive writes per day (DWPD). The drive uses a Gen-3 carrier tray for SFF-3 SAS bays in system units but is incompatible with EXP24S Gen2 drawers due to carrier differences. It delivers reliable, high-speed storage for virtualization and data-intensive applications, with error correction for robust performance. The ESBK is optimized for Power9 servers like 9009-41A and supports demanding workloads like ERP and databases. This SSD offers a cost-effective solution for upgrading system units, enhancing scalability in challenging environments, ensuring efficiency and data integrity.

Compatibility
The IBM ESBK 1.55TB Enterprise SAS 4k SFF-3 SSD (ESBK) is compatible with IBM Power Systems running IBM i, providing high-performance storage for system units. It supports SFF-3 SAS bays in Power9 servers, such as 9009-41A, 9009-42A, 9119-MME, and 9040-MR9, but is incompatible with EXP24S Gen2 drawers due to carrier differences. The drive, with CCIN 5B45, uses 4224-byte sectors for IBM i and requires compatible SAS controllers (e.g., EJ0L, EJ14) for connectivity. It cannot be mixed in arrays with drives of different sector sizes. The ESBK is optimized for virtualization and data-intensive applications, ensuring reliable performance for workloads like ERP and databases in demanding environments:
- Power9: 9009-41A, 9009-42A, 9119-MME, 9040-MR9 for IBM i.
- Requires EJ0L or EJ14 SAS controllers with SFF-3 bays.
- Supports 4224-byte sectors for IBM i system compatibility.
Note: Incompatible with EXP24S Gen2 drawers; requires matching sector sizes.
