NVMe FlashCore Storage Module (Gen 5)

IBM FlashSystem NVMe FlashCore Module Gen 5 (FCM5)

The current IBM NVMe FlashCore Module generation, cataloged in 6.6 TB, 13.2 TB, 26.4 TB, and 52.8 TB usable capacities across the FlashSystem 5600, 7600, and 9600, plus a 105.6 TB capacity exclusive to the FlashSystem 9600.

Storage Systems Vendor: IBM

Program Overview

FlashCore Module Gen 5 (FCM5) is a physical break from the four generations before it. FCM1 through FCM4 all share the same U.2 NVMe drive form factor, which is why an older FlashSystem could sometimes be upgraded from one of those generations to the next. FCM5 moved to the EDSFF form factor introduced with the FlashSystem 5600, 7600, and 9600 refresh, so it is not a drop-in upgrade for any earlier FlashSystem model, including a fully current FCM4 array.

Buyers should treat an FCM5 order as tied to a specific current-generation platform purchase or expansion, not a media refresh on existing hardware. IBM pairs FCM5 with embedded ransomware-detection telemetry and quantum-safe encryption carried over from FCM4, plus the new 105.6 TB capacity point exclusive to the FlashSystem 9600.

Best Fit

Best fit for buyers purchasing or expanding a current-generation FlashSystem 5600, 7600, or 9600 array. Not applicable to any earlier FlashSystem model regardless of firmware level, since the drive bay itself changed form factor.

What this program helps with

  • 6.6 TB usable capacity -- Feature Code ADSJ -- FlashSystem 5600, 7600, and 9600
  • 13.2 TB usable capacity -- FlashSystem 5600, 7600, and 9600 -- confirm current feature code with an IBM configurator or reseller quote
  • 26.4 TB usable capacity -- Feature Code ADSL -- FlashSystem 5600, 7600, and 9600
  • 52.8 TB usable capacity -- Feature Code ADSM -- FlashSystem 5600, 7600, and 9600
  • 105.6 TB usable capacity -- Feature Code ADSN -- FlashSystem 9600 exclusively

What to vet before shortlist

  • Confirm the target array is a FlashSystem 5600, 7600, or 9600 before quoting FCM5; it is not installable in a FlashSystem 9500, 7300, 5300, or any older U.2-bay model
  • Use the feature code to validate the order path with an IBM configurator or reseller quote; exact numeric part numbers should be confirmed directly rather than assumed from capacity alone
  • The 105.6 TB capacity point is exclusive to the FlashSystem 9600 and is not cataloged for the 5600 or 7600
