IBM AHSG 19.2TB NVMe FlashCore Module 4 – FCM4

The IBM AHSG 19.2TB FlashCore Module 4 is an enterprise NVMe storage option for supported IBM FlashSystem 9500 4666-AH8 4983-AH8 and 4666-UH8 configurations. The IBM AHSG 19.2TB FlashCore Module 4 combines flash capacity, hardware compression, encryption and computational-storage capabilities in a 2.5-inch form factor for IBM FS9500 FlashSystem. The IBM 19.2TB FlashCore Module 4 FCM4 may also have IBM AHSG ADSG and AGSG feature codes, and may have 03NK830 03LG010 and 03LG015 part numbers depending on the IBM FlashSystem model the FCM4 was ordered for.

The IBM AHSG 19.2TB FlashCore Module 4 FCM4 is designed for supported control-enclosure NVMe bays, FCM4 provides a capacity expansion and replacement option for eligible IBM FlashSystems. The IBM AHSG 19.2TB FlashCore Module 4 FCM4 has computational-storage functions that supports IBM’s ransomware threat-detection capabilities when the array, firmware and system software meet the IBM's FlasySystem requirements.

Use the Email Price feature to request IBM AHSG 03NK830 pricing, ask questions or confirm compatibility with your IBM FlashsSystem model and configuration. All product sales include warranty, support and optional professional services may be purchased installation and configuration assistance. You should provide your IBM FlashSystem machine type and model, existing drive label and required quantity for a quotation covering replacement modules, expansion requirements or maintenance spares. The IBM 19.2TB FlashCore Module 4 FCM4 may also have IBM ADSG and AGSG feature codes and may have 03LG010 and 03LG015 part numbers depending on the IBM FlashSystem model the FCM4 was ordered for.

IBM AHSG FCM4 Features and Benefits

• 19.2TB module capacity: a high-capacity FlashCore option for supported enterprise storage configurations.
• PCIe Gen 4 NVMe: storage connectivity designed for supported IBM NVMe control enclosures.
• Hardware compression: data compression takes place within the module, helping reduce physical storage consumption for compressible workloads.
• Integrated encryption: FlashCore encryption capability works within the system’s encryption and key-management configuration.
• Computational storage: module-level processing collects statistics used by supported IBM threat-detection functions.
• Supported FCM3 upgrade paths: FCM4 can provide replacement or expansion capacity where IBM permits the combination.

Technical Specifications

Corresponding IBM FlashSystem Feature Codes

IBM uses different ordering feature codes for the 19.2TB FCM4 capacity option across its storage platforms. The matrix below identifies those platform-specific references. A matching capacity and generation do not, by themselves, establish that every carrier assembly or service revision is interchangeable.

Hardware Compression and Effective Capacity

IBM publishes a 57.6TB effective-capacity figure for the 19.2TB FCM4 capacity point. This corresponds to a 3:1 compression assumption. Compression savings depend on the stored data: already-compressed media, encrypted data and other low-compressibility workloads may achieve substantially less reduction. Effective capacity is not additional physical flash or guaranteed application-usable space. RAID protection, rebuild capacity, metadata and the storage configuration must also be considered when sizing an installation.

Replacing or Expanding an FCM3 Installation

IBM FlashSystems allow a fourth-generation modules FCM4 to be intermixed with third-generation modules FCM3 in supported arrays. In that arrangement, the FCM4 operates with FCM3-equivalent functionality. An all-FCM4 RAID array is required for IBM FCM4 specific functions. Consequently, replacing one failed module with FCM4 does not by itself convert an existing FCM3 array into a fully enabled fourth-generation array. Plan the array layout and software requirements around the intended capacity and functionality.

FCM4 Ransomware Threat-Detection Requirements

IBM FCM4 collects statistics that help supported IBM software identify suspicious changes in workload behaviour. This capability depends on the complete storage configuration, rather than the drive alone.

• Use a qualifying array composed entirely of FCM4 modules.
• IBM’s published introduction requirements include Storage Virtualize 8.6.3 or later and compatible FCM4 firmware.
• Confirm current software, firmware, analytics-service and entitlement requirements for the installation.
• Maintain suitable backup and recovery arrangements alongside threat detection.
