NVMe U.2 Internal Storage for Power 11
Direct NVMe U.2 storage bays built into every Power11 chassis, scaling from 12.8 TB raw on the S1112 up to 244.8 TB raw on the S1124 and L1124.
Every current Power 11 model uses direct NVMe U.2 drive bays for internal storage, a generational step up in density and throughput from the SAS/SATA drive bays common on older Power hardware.
Internal NVMe capacity by model
Maximum internal NVMe storage by model
| Model | Max Raw Capacity | Mirrored (IBM i typical) |
|---|---|---|
| S1112 | 12.8 TB | 6.4 TB |
| S1122 | 122.4 TB (or 51.2 TB config) | ~25.6-61.2 TB |
| S1124 | 244.8 TB (or 102.4 TB config) | ~51.2-122.4 TB |
| L1122 | 122.4 TB (or 51.2 TB config) | ~25.6-61.2 TB |
| L1124 | 244.8 TB (or 102.4 TB config) | ~51.2-122.4 TB |
| E1150 | 153 TB per node | Varies by RAID/mirror policy |
| E1180 | 102.4 TB per node | Varies by RAID/mirror policy |

Frequently Asked
What storage options does Power 11 support?
Every current Power 11 model uses direct NVMe U.2 internal storage bays, from 12.8 TB raw on the S1112 up to 244.8 TB raw on the S1124 and L1124. Additional NVMe capacity can be added via the external NED24 expansion drawer, and further PCIe-attached SAN or tape connectivity is added through the Gen4 I/O expansion drawer.
Does an IBM FlashCore Module go in Power 11's NED24 expansion drawer?
No. The NED24 drawer takes standard direct-attached NVMe drives, not FlashCore Modules. FlashCore Modules are housed inside external IBM FlashSystem or Storage Virtualize based arrays and reach a Power 11 partition over Fibre Channel SAN through a supported host adapter, not through the NED24 drawer or internal NVMe U.2 bays.
