    • IBM Storage FlashSystem 9500

    IBM Storage FlashSystem 9500

    The IBM FlashSystem 9500 (models 4666-AH8 / 4983-AH8) is a high-end, enterprise-grade all-flash NVMe storage system in a 4U rack-mounted control enclosure. It features dual active-active node canisters with powerful processing, massive cache, and support for up to 48 NVMe drives (including IBM FlashCore Modules with hardware compression and encryption). Powered by IBM Storage Virtualize software, it delivers extreme performance, inline data reduction (compression, deduplication), AI-powered threat detection, cyber resilience features, and scalability through clustering and expansion. Ideal for mission-critical workloads requiring unrivaled throughput, low latency, and high availability with NVMe-oF support.

    Key Features

    • 4U high-density control enclosure with up to 48 NVMe flash drive slots for massive raw capacity.
    • Dual node canisters, each with two 24-core processors and up to 1.5 TB memory per node (3 TB total per enclosure).
    • IBM FlashCore Modules (third-generation) with performance-neutral hardware compression, encryption, and MicroLatency technology.
    • Support for industry-standard NVMe drives and optional Storage Class Memory for tiering.
    • Versatile connectivity: onboard Ethernet, optional 32/64 Gb Fibre Channel, 25/100 Gb Ethernet for iSCSI/NVMe/TCP/RDMA.
    • Advanced cybersecurity: inline ransomware detection, Safeguarded Copy, multifactor authentication, and rapid recovery.
    • Scale-out clustering (up to 32 systems in a grid) and scale-up with SAS expansion enclosures.
    • IBM Storage Virtualize for thin provisioning, Easy Tier, snapshots, replication (including 3-site HyperSwap), and transparent cloud tiering.

    Technical Specifications

    • Form Factor: 4U rack-mounted control enclosure.
    • Processors: 4 x 24-core processors (two per node canister).
    • Cache/Memory: Up to 3 TB total (1.5 TB per node; configurable options from 1 TB to 3 TB).
    • Drive Slots: Up to 48 x 2.5-inch NVMe-capable flash drives.
    • Maximum Raw Capacity: Up to 922 TB raw per enclosure (with FCM); higher effective with 3:1+ compression/deduplication.
    • Interfaces: Onboard Ethernet; up to 48 PCIe slots across enclosure for FC (32/64 Gb), Ethernet (10/25/100 Gb), SAS host/expansion.
    • Connectivity Protocols: NVMe-oF over FC, NVMe/TCP, iSCSI, FCP-SCSI.
    • Power: Redundant hot-swappable power supplies and fans with battery backup.
    • Performance: Extreme throughput and IOPS optimized for demanding enterprise workloads (specific metrics vary by config; consult IBM for benchmarks).

    Available Configurations

    Base models:

    • 4666-AH8: IBM FlashSystem 9500 SFF NVMe Control Enclosure (standard).
    • 4983-AH8: IBM FlashSystem 9500 SFF NVMe Control Enclosure (with Expert Care / licensed code variant).
    • 4666-UH8: Utility model (Capacity on Demand billing via Storage Insights).

    Supports IBM FlashCore Modules (FCM) and industry-standard NVMe drives (similar to other FlashSystem series; specific FCM capacities include 4.8 TB, 9.6 TB, 19.2 TB, 38.4 TB variants with hardware acceleration). Expansion enclosures: SAS-based SFF/LFF/HD models (e.g., compatible with 12G, 24G, 92G patterns from related systems). Drives and I/O adapters configured via IBM feature codes at order time.

    Compatibility

    • Host Interfaces: NVMe-oF on FC/TCP, iSCSI, FCP; supports switched fabric and multipathing.
    • Expansion: SAS enclosures (requires SAS adapter feature codes); up to multiple chains per control enclosure.
    • Software: IBM Storage Virtualize 8.5+ (8.6+ for 4983 models) for virtualization, tiering, data reduction, replication, and security features.
    • Environments: Integrates with VMware, Microsoft Hyper-V, Red Hat OpenShift, Kubernetes, and other platforms via block protocols.
    • Clustering: Federate up to 32 independent systems into a grid for scale-out performance and capacity.
    • No intermixing with older/non-compatible machine types.
