Memory

Slots
16 DIMM (8 per processor, 1 DIMM per channel)
Max
2 TB using 16 × 128 GB 3DS RDIMM
Type
Lenovo TruDDR4 RDIMM/3DS RDIMM, up to 3200 MHz
Persistent memory
Up to 8 × Intel Optane PMem 200 Series modules (4 per processor), installed alongside system-memory DIMMs
Protection
ECC, SDDC (x4 DIMMs), ADDDC/RBS (x4 DIMMs, requires Gold or Platinum CPU), memory mirroring

Storage

Bays
2 × 2.5" hot-swap SAS/SATA/NVMe, or 6 × EDSFF E1.S hot-swap NVMe (requires both processors installed)
Controllers
Onboard SATA (Intel VROC SATA RAID); onboard NVMe (Intel VROC NVMe RAID); optional RAID 530-4i (cacheless) or RAID 930-4i (2 GB flash-backed cache) for SAS/SATA, both RAID 0/1
M.2
1–2 M.2 SATA and/or NVMe drives via M.2 RAID Enablement Kit (SATA-only, NVMe-only, or SATA/NVMe with VROC)
Max capacity
61.44 TB using 2 × 30.72 TB 2.5" SAS/SATA SSD; 30.72 TB using 2 × 15.36 TB 2.5" NVMe SSD; 4.8 TB using 2 × 2.4 TB 2.5" HDD; 46.08 TB using 6 × 7.68 TB EDSFF NVMe SSD

Expansion

I/O slots
2 × 216-pin high-density I/O expansion connector, each PCIe 4.0 x16 host interface
Note
No integrated Ethernet controller and no Fabric Connector support — a network or Fibre Channel mezzanine adapter is required in each I/O slot to reach the chassis switch bays

Networking

10 GbE
Flex System CN4052S 2-port and CN4054S 4-port Virtual Fabric Adapters (standard and Advanced)
