With 2.5-inch drive bays, mid (internal) bays and rear drives are mutually exclusive. See Supported drive bay combinations for details. Mid bays are hot-swap drive bays and are accessible by removing the top cover of the server. 4x 3.5-inch front drive bays can be configured as AnyBay supporting SAS, SATA or NVMe. 2.5-inch drive bays can be configured as NVMe, supporting 28x NVMe drives with direct connections (no oversubscription), or 32x NVMe drives with 2:1 oversubscription.
Maximum internal storage
All NVMe: 184.32 TB using 24x 6.4 TB NVMe (front) + 8x 3.84TB NVMe SSDs (mid)
All SSDs: 245.76 TB using 32x 7.68TB SSDs (24x front, 8x mid)
All HDDs: 280 TB using 20x 14TB 3.5-inch HDDs (12x front, 4x mid, 4x rear)
Mix of SSDs/HDDs supported but not in the same array

Storage controller

Optical drive bays No internal optical drive.
Tape drive bays No internal backup drive.
Network interfaces Dedicated OCP 3.0 SFF slot with PCIe 4.0 x16 host interface. Supports a variety of 2-port and 4-port adapters with 1GbE, 10GbE and 25GbE network connectivity. One port can optionally be shared with the ASPEED management processor for Wake-on-LAN and NC-SI support.

PCI Expansion slots
A total of up to 9 PCIe 4.0 slots (8 with rear access, 1 internal for a RAID adapter) plus a slot dedicated to the OCP adapter. Slot availability is based on riser selection.
Slot length is dependent on the use of a mid-chassis drive cage: If the mid drive cage is present then slots are half-length; if the mid drive cage is not present, then slots are full-length.
Riser 1: Slots 1, 2 and 3 – all FHHL or FHFL (16 or 32 lanes)
Option 1*: 1=x16, 2=x8, 3=x8
Option 2*: 1=x16, 2=x16 (no slot 3)
Option 3: 3=x16 (no slot 1 or slot 2)
Option 4: 1=x16 (no slot 2 or slot 3)
Riser 2: Slots 4, 5, and 6 – slot size varies (32 lanes)
Option 1: 4=x16, 5=x8, 6=x8
Option 2: 4=x16, 5=x16 (no slot 6)
Option 3: 6=x16 (no slot 4 or slot 5)
Riser 3: Slots 7 and 8 – both FHHL or FHFL (16 or 32 lanes)
Option 1*: 7=x8, 8=x8
Option 2*: 7=x16, 8=x16
Slot 9: Internal PCIe 4.0 x8 low-profile slot for internal drive controller
* The use of 32 lanes with Riser 1 or the use of Riser 3 imposes restrictions on the use of the onboard SATA controller or the use of the M.2 Module or both. See the I/O expansion section for details.
