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
