Dell PowerEdge R7625 Rack Server | Configurable

There are a few chassis options.

• Up to 8x 3.5" SAS4/SATA (HDD/SSD)
• Up to 12x 3.5" SAS/SATA (HDD/SSD)
• Up to 8x 2.5" SAS/SATA/NVMe (HDD/SSD)
• Up to 16x 2.5" SAS/SATA/NVMe (HDD/SSD)
• Up to 24x 2.5" SAS/SATA/NVMe (HDD/SSD)
• Up to 8x EDSFF E3.S NVMe Gen5
• Up to 16x EDSFF E3.S NVMe Gen5
• Up to 32x EDSFF E3.S NVMe Gen5

Rear drive support is limited to two configurations: 12 LFF and 24 SFF drive bays. When rear drive bays are installed, GPU support is not available, and some PCIe slots will be occupied as a result.

• Up to 2x 2.5" SAS4/SATA/NVMe (HDD/SSD)
• Up to 4x 2.5" SAS4/SATA/NVMe (HDD/SSD)

The Dell PowerEdge R7625 rack server supports up to two 4th Generation AMD EPYC 9004 Series processors, with up to 128 cores per processor for enterprise-grade performance. Enhanced processing efficiency comes from 32MB of L3 cache per core, while integrated I/O supports up to 128 PCIe Gen5 lanes on Dell platforms (AMD supports up to 160 I/O lanes in 2P configurations) — making this high-performance server solution ideal for HPC workloads.

The Dell PowerEdge R7625 offers two cooling options for its AMD processors: air cooling or Direct Liquid Cooling (DLC). Air-cooled configurations support up to six high-performance Silver or Gold hot-plug fans. GPU configurations require Gold fans paired with an L-Type heat sink, as the Standard heat sink is too tall for GPU clearance.

Optional Direct Liquid Cooling (DLC) is required for certain CPU SKUs and configurations on the Dell PowerEdge R7625. Systems with DLC installed and a 12-bay chassis require Gold fans, and any processor with a 400W TDP must use DLC for proper thermal management. DIMM type and chassis configuration should be verified before installing DLC, as not all systems support it. Refer to the technical manual and Thermal Restriction Matrix for complete rules, limitations, and configuration guidance.

The Dell PowerEdge R7625 supports up to 24 DIMMs (12 per socket), with up to 6TB of total memory and speeds up to 4800 MT/s.

The Dell PowerEdge R7625 supports registered DIMMs (RDIMMs), which use a buffer to reduce memory loading and enable greater density — allowing the platform to reach its maximum memory capacity. Unbuffered DIMMs (UDIMMs) are not supported.

• Supports registered ECC DDR5 DIMMs only
• DDR4 DIMM memory is not supported.
• Memory DIMM slots are not hot-pluggable.
• Do not mix DIMM module types within a memory channel
• All must be RDIMM or 3DS RDIMM module types with same ECC configuration.
• Do not mix x4 and x8 DIMMs with a memory channel.

The Dell PowerEdge R7625 supports up to two 10/100/1000 Mbps Network Interface Controller (NIC) ports, available via the embedded LAN on Motherboard (LOM) and integrated Open Compute Project (OCP) cards.

• LOM: 2x 10GbE
• OCP: 4x 25GbE

The Dell PowerEdge R7625 rack server supports up to eight PCIe slots, including six full-height or two low-profile riser slots, with up to six x16 slots available. With more than 13 PCIe expansion riser configurations, businesses can find the right setup for their specific workload. Installing rear drives will occupy some of these PCIe slots.

The Dell PowerEdge R7625 supports up to two double-wide 300W GPUs or six single-wide 75W accelerators, with High-Performance Gold fans required across all GPU configurations. GPU support is not available on 12x3.5" configurations or systems with a rear drive module installed. Rear drive support is limited to two options: the 12 LFF and 24 SFF chassis configurations.

• Slot 1: 1 x8 Gen5 or 1 x8 Gen4 Full height, Half-length
• Slot 2: 1 x8/1 x16 Gen5 or 1 x8 Gen4 Full height, Half-length or 1 x16 Gen5 Full height Full length
• Slot 3: 1 x16 Gen4 Low profile, Half-length
• Slot 4: 1 x8 Gen4 Full height, Half-length
• Slot 5: 1 x8 Gen4 Full height, Half-length or 1 x16 Gen4 Full height, Full length
• Slot 6: 1 x16 Gen4 Low profile, Half-length
• Slot 7: 1 x8/1 x16 Gen5 or 1 x8 Gen4 Full height, Half-length or 1 x16 Gen5 Full height, Full length
• Slot 8: 1 x8 Gen5 or 1 x8 Gen4 Full height, Half-length

Dell's RAID controller lineup includes the fPERC solution, which delivers a base RAID hardware controller without consuming a PCIe slot — using a small form factor and high-density connector to the base planar. Refer to the cabling guides in the manuals below for setup details.

The system supports a hot-swappable boot device (BOSS-N1), which holds 2x M.2 NVMe SSD cards.

The system also includes a slot for an internal USB stick for boot purposes. For more detailed information on boot options, refer to the manual below.
