The Dell PowerEdge R660 is a 1U dual-socket rack server engineered for demanding enterprise workloads like dense database analytics and high-density virtualization. Configuration includes 32 DIMM slots, 3 PCIe slots, 1 OCP slot, and 1 LOM, with 3 available chassis options supporting SAS, SATA, and NVMe drives — details on each storage configuration are outlined below.
| Chassis | Supported Configurations |
|---|---|
| No Drive Chassis | Zero drives (no backplane) |
| 8SFF |
|
| 10SFF + Optional Rear 2SFF Drive |
|
| NOTE: The Rear drive option is only shown in the 10SFF. | |
| Form Factor | Type | Speed | Rotational Speed | Capacities |

| 2.5" | SAS | 24 Gb | SSD | 1.92 TB, 1.6 TB, 800 GB, 3.84 TB, 960 GB, 7.68 TB |
| 2.5" | SATA | 6 Gb | SSD | 1.92 TB, 480 GB, 960 GB, 3.84 TB |
| 2.5" | NVMe | Gen4 | SSD | 1.6 TB, 3.2 TB, 6.4 TB, 1.92 TB, 3.84 TB, 15.63 TB, 7.68 TB, 800 GB, 400 GB |
| 2.5" | DC NVMe | Gen4 | SSD | 3.84 TB, 960 GB |
| 2.5" | SAS | 12 Gb | 10 K | 600 GB, 1.2 TB, 2.4 TB |
Processor | 4th / 5th Generation Intel Xeon Scalable
Configurations support up to two 4th or 5th Generation Intel Xeon Scalable processors, offering up to 56 cores each with optional Intel® QuickAssist Technology. The 8470Q and 6458Q models require liquid cooling exclusively, and processor mixing isn't recommended — if one socket uses a liquid-cooled processor, the second must match.
- Faster UPI with up to four Intel Ultra Path Interconnect (Intel UPI) at up to 16 GT/s, increasing multi socket bandwidth
- More, faster I/O with PCI Express 5 and up to 80 lanes (per socket)
- Enhanced Memory Performance with DDR5 support and memory speed up to 4800 MT/s in one DIMM per channel (1DPC) and 4400 MT/s in two DIMM per channel (2DPC)
- New built-in accelerators for data analytics, networking, storage, crypto, and data compression
The Dell PowerEdge R660 supports Liquid Cooling and Air Cooling options.
The Dell PowerEdge R660 supports either four sets of Standard cooling fans or four sets of High-Performance Gold cooling fans, with the choice determined by processor TDP.
Installing rear drives in the 10SFF chassis requires Gold fans.
A processor exceeding 185W TDP requires the Direct Liquid Cooling module to be installed.
Refer to the R660 installation manual for further cooling details.
Several cooling shrouds apply to specific configurations on this system — a CPU shroud is required for all air-cooled builds, and a PCH shroud is needed when no riser is installed.
An air-cooled build with a 2x 2.5" rear-drive configuration requires the rear drive shroud.
Installing an A2 GPU requires a blank on the R1P riser to maintain proper airflow.
32 DDR5 DIMM slots support up to 8TB of RDIMM capacity, with speeds reaching 4800 MT/s (or 5600 MT/s with 5th Gen CPUs) — registered ECC DDR5 DIMMs only.
| DIMM type | Rank | Capacity | DIMM rated voltage and speed | Operating Speed | |
|---|---|---|---|---|---|
| 1 DIMM per channel (DPC) | 2 DIMMs per channel (DPC) | ||||
| RDIMM | 1 R | 16 GB | DDR5 (1.1 V), 4800 MT/s | 4800 MT/s | 4400 MT/s |
| 2 R | 32 GB, 64 GB | DDR5 (1.1 V), 4800 MT/s | 4800 MT/s | 4400 MT/s | |
| 4 R | 128 GB | DDR5 (1.1 V), 4800 MT/s | 4800 MT/s | 4400 MT/s | |
| 8 R | 256 GB | DDR5 (1.1 V), 4800 MT/s | 4800 MT/s | 4400 MT/s | |
NOTE: Permanently removing a memory module on a processor with TDP ≥250W requires installing a memory module blank, following a process similar to standard DIMM installation.
The Dell PowerEdge R660 supports up to two NIC ports via the embedded LOM card and up to four ports through the OCP card, with the option to install either card independently or both together.
A no-riser configuration is available on the PowerEdge R660; in this setup, the PCH air shroud must be installed to maintain correct airflow.

The server's 3 rear PCIe slots can each be filled with a single-wide 75W GPU. Installing an A2 GPU calls for a dedicated air shroud, along with an A2 blank on the R1P riser when using a full-height riser configuration — note that only risers labeled with a "P" support GPU installation.
Dell's fPERC solution stands out in the RAID controller lineup by delivering a base RAID hardware controller that doesn't consume a PCIe slot, thanks to its compact form factor and high-density connector to the base planar.
The 16G PERC controller lineup builds substantially on the 15G family, carrying forward the Value and Value Performance tiers. New to 16G is the Avenger-based Premium Performance tier, a high-end option designed to boost IOPS and enhance SSD performance.

The BOSS-N1 offers 2x hot-swappable M.2 NVMe SSDs with hardware RAID, supporting single-drive RAID 0 or dual-drive RAID 1.
The BOSS card isn't supported under all thermal conditions; when it's not installed, a BOSS blank must take its place.
