IBM 4.8 TB NVMe FlashCore Module 4 for FlashSystem 5200 (4662-AGSE)

4662-AGSE is the feature code AGSE of machine type 4662 for a 4.8 TB NVMe FlashCore Module 4, the fourth generation of IBM FlashCore Module, for the IBM FlashSystem 5200 control enclosure. The control enclosure takes up to 12 NVMe 2.5-inch drives, and the 4.8 TB FCM4 is the smallest of the FCM4 sizes.

IBM FlashCore Modules combine IBM MicroLatency technology, flash management and reliability in a 2.5-inch SFF NVMe drive with built-in, performance-neutral hardware compression and encryption. FCM4 introduced 176-layer QLC NAND, enhanced FPGA acceleration, improved compression efficiency and lower latency for compressed workloads. Hardware-assisted compression on FCM3, FCM4 and FCM5 reaches ratios of up to 3:1, depending on the workload.

A FlashCore Module array needs at least six drives, uses DRAID 6 (recommended) or DRAID 5, and every module in an array must have the same capacity. FCM3 and FCM4 can share an array, but the FCM4 modules then behave as FCM3 without the enhanced ransomware detection; the full ransomware detection needs every drive to be FCM4 and IBM Storage Virtualize code 8.6.3 or later. FCM2 cannot share an array with FCM3 or FCM4.

Other FCM4 codes in the same FlashSystem 5200 drive table are AGSF at 9.6 TB, AGSG at 19.2 TB and AGSH at 38.4 TB, and the FCM3 codes AGSA to AGSD cover 4.8, 9.6, 19.2 and 38.4 TB.
