Product Description
IBM ESB8 387GB Enterprise SAS 4k SFF-3 SSD for AIX/Linux
The IBM ESB8 387GB Enterprise SAS 4k SFF-3 SSD for AIX/Linux is a high-performance enterprise solid-state drive optimized for read-intensive and mixed-use workloads on IBM Power Systems running AIX and Linux. This 2.5-inch SFF-3 SSD delivers 387 GB usable capacity, 12 Gb/s SAS connectivity, 4K sector format, and high endurance, making it ideal for database, virtualization, ERP, analytics, and general-purpose enterprise applications requiring low latency and high IOPS.
Product Description
The IBM ESB8 (feature code ESB8, part number typically 00E9892 or related variant, CCIN often 5B10 or similar) is a 2.5-inch Small Form Factor (SFF-3) SAS solid-state drive designed for IBM Power Systems servers. It provides 387 GB of enterprise-class flash storage with a 12 Gb/s SAS interface (dual-port) and native 4K sector format, ensuring optimal performance and compatibility with AIX and Linux environments. The drive uses a standard hot-plug SFF-3 carrier compatible with internal Power Systems bays. It supports RAID 0/1/5/6/10 via the host server's integrated controller or VIOS, with advanced features including power-loss protection capacitors, end-to-end data protection (T10 DIF/DIX), and high endurance for sustained write-intensive operations. This SSD is qualified for mission-critical AIX and Linux workloads on Power8 and Power9 systems, offering significant IOPS and latency improvements over traditional HDDs while maintaining full backward compatibility with 6 Gb/s SAS infrastructure.
Features
- 387 GB enterprise-class capacity in 2.5-inch SFF-3 form factor.
- 12 Gb/s SAS interface (backward compatible with 6 Gb/s SAS).
- 4K (4096-byte) native sector format for optimal AIX/Linux performance.
- High endurance for mixed-use workloads (typically 1–3 DWPD over 5 years).
- Power-loss protection circuitry to safeguard data during unexpected power events.
- Hot-plug SFF-3 carrier for zero-downtime maintenance.
- Full RAID support (0/1/5/6/10) via attached Power Systems controller or VIOS.
- Advanced error correction, wear-leveling, and T10 DIF/DIX end-to-end protection.
- LED status indicators on carrier for activity and fault conditions.
