    • Drives for FlashSystem 5300 Expansion

    Drives for FlashSystem 5300 Expansions

    The IBM FlashSystem 5300 expansion enclosures support a variety of SAS-based drives, including nearline HDDs (7.2K RPM), enterprise HDDs (10K RPM), and high-performance SAS flash SSDs. These drives are compatible with the 4662-12G (LFF), 4662-24G (SFF), and 4662-92G (HD LFF) expansion models, enabling tiered storage for capacity optimization. Drives are dual-port, hot-swappable, and can be intermixed within an enclosure if they share the same form factor and technology class. Formatted primarily in DRAID 6 for reliability and faster rebuilds, these options allow scaling to petabyte levels with hybrid flash and disk configurations. Specific drive feature codes and capacities align with those supported on similar FlashSystem models (e.g., 7300 expansions), configured at order time via IBM options.

    Key Features

    • SAS 12 Gbps interface for high throughput and reliability.
    • Mix of nearline HDDs for cost-effective bulk storage, enterprise HDDs for balanced performance, and SAS SSDs for faster access tiers.
    • Model-specific support: 12G for LFF nearline-focused, 24G for SFF mixed options, 92G for high-density hybrid tiers.
    • Intermixing of compatible drives within the same enclosure (same form factor and class).
    • Hot-swappable and dual-port design for high availability.
    • Optimized for IBM Storage Virtualize tiering (Easy Tier) and data services.
