IBM 283GB 15,000 RPM SAS 6Gb/s Enterprise Hard Drive

Model: ST9300653SS | IBM PN: 74Y6497 | Feature Code: 1953 | 283GB Capacity | 15K RPM

The IBM 74Y6497 is a high-performance mission-critical drive based on the Seagate Savvio 15K.3 platform. Much like the 00E8681 mentioned earlier, this drive is specifically tailored for IBM Power Systems (AIX, IBM i, and Linux on Power). It features a unique 283GB capacity, which is the result of specialized 528-byte sector formatting. This formatting is essential for IBM i environments, providing the extra space needed for hardware-level data tags and parity checking.

📊 Technical Specifications

  • Capacity: 💾 283 GB (Formatted for IBM Power/i)

  • Interface: ⚡ SAS 6Gb/s (Dual Port)

  • Spindle Speed: 🏎️ 15,000 RPM

  • Cache: 🧠 64 MB

  • Form Factor: 📏 2.5-inch SFF (15mm)

  • Sector Format: 💾 528-byte sectors

  • Average Latency: ⏱️ 2.0 ms

  • Sustained Transfer Rate: 🏎️ 202 MB/s

✅ Product Overview

  • Optimized for IBM i & AIX: This drive (Feature Code 1953) is a standard for Power7 and Power8 environments. The 528-byte sectoring allows the system to perform advanced error detection and correction that standard 512-byte drives cannot handle.

  • Peak Mechanical Speed: With a 15,000 RPM rotation speed, this drive offers the lowest possible latency for a mechanical disk, ensuring that high-transaction workloads aren't slowed down by disk "seek" times.

  • Dual-Port SAS Pathing: Supports full path redundancy. In professional IBM Power configurations, this allows two different SAS adapters to access the drive, ensuring no single point of failure for the storage path.

📦 Compatibility & Use Case

  • Target Systems: Specifically for IBM Power Systems (S814, S822, S824, 720, 740, 750) and EXP24S (#5887) or EXP24SX (#ESR1) expansion drawers.

  • Carrier Type: Usually found in the SFF-1 or SFF-2 tray. Verify which tray style your specific Power server or expansion drawer requires.

  • Ideal Workloads: Transactional databases (DB2), mission-critical system partitions (LPARs), and high-speed temporary storage (SWAP/TEMP) for AIX and IBM i.

⚠️ Critical Compatibility Note: This is a 528-byte formatted SAS drive. It is not compatible with standard Windows, Linux (x86), or Mac computers. It will only be recognized by specialized IBM Power Systems controllers. Attempting to use this in a consumer PC will result in the drive not being recognized.

The IBM 74Y6497 is a specialized performance workhorse, delivering the high IOPS and extreme data integrity required by enterprise-level IBM Power environments.
