Why R660 Fleets Are Moving to the R670

The R660 was the 1U workhorse of the Xeon Scalable 4th-generation era. The R770’s 1U sibling, the PowerEdge R670, replaces it with the Intel Xeon 6 платформа – and the differences are not a refresh, they are a generation change: DDR5 at 6400 MT/s instead of 5600, EDSFF E3.S NVMe bays instead of 2.5-inch cages, the DC-MHS service architecture, and integrated 88-lane PCIe Gen5 per CPU.

This guide walks the migration from an R660-class fleet to the R670 using the official Dell technical-guide data, so the decision is spec-for-spec before a single quote is issued.

Full Specifications

Parameter Deep-Dive

сеть

Two OCP NIC 3.0 slots sit on the front (cold-aisle front-I/O build) or the rear (rear-I/O build), with card options spanning 1GbE BASE-T through 100GbE/400GbE. A dedicated iDRAC management port is always present, and the DC-SCM carries the management fabric on the DC-MHS architecture – no dedicated PERC on the front, keeping the airflow open for drives.

Front Panel and I/O

The right control panel carries the power button with LED, USB 2.0 Тип-С, system ID button, ambient temperature sensor, host status LED and system health indicator. Front-I/O builds add optional USB 2.0, Mini-DisplayPort and DB9 serial on the cold aisle; rear-I/O builds put 2x USB 3.1 and VGA at the back.

Riser and PCIe Gen5

Each Xeon 6 CPU integrates 88 PCIe 5.0 переулки (UPI at 16/20/24 GT/s), feeding up to 3×16 Gen5 slots via the risers. Accelerator support tops out at 3x 75W single-width cards; the CXL 2.0 memory-pooling path is available on P-core SKUs for scale-up memory tiers.

RAID and Boot

Boot is handled by the БОСС-Н1 DC-MHS – аппаратный RAID 1 across 2x M.2 NVMe (480/960 ГБ) – or an M.2 interposer on the same DC-MHS slot. External storage attaches via H965e/HBA355e; the front PERC slot is intentionally omitted to maximize E3.S airflow and capacity.

Безопасность

PowerEdge platform security applies at the silicon level: UEFI Secure Boot, доверенный платформенный модуль 2.0, a silicon root of trust, and signed firmware verified on every update path. The DC-SCM adds physical isolation of the management plane from the compute board – a server that can be serviced without exposing management credentials.

Управление

iDRAC with Lifecycle Controller, iDRAC Прямой (USB), and the iDRAC RESTful API with Redfish cover out-of-band management, virtual media, telemetry and automation – SNMP and the full OpenManage Enterprise stack are supported for fleet monitoring.

Операционные системы

Certified across VMware ESXi 8, Сервер Microsoft Windows 2022/2025, Ред Хэт Энтерпрайз Линукс 9, SUSE Linux корпоративный сервер 15, и Убунту 22.04/24.04 LTS.

Workload Profile: Where the 1U Xeon 6 Fits

The R670 targets four workload families, and each one stresses a different part of the spec:

• Cloud-native microservices: 144 E-core SKUs give the highest core density per 1U for horizontally scaled container fleets – the E-core design trades single-thread speed for massive parallelism at low power.
• Виртуализация: 32 DIMMs at 6400 MT/s plus 3×16 Gen5 I/O handle dense VM consolidation; the P-core variants carry the single-thread workloads comfortably.
• HPC and analytics: 88 PCIe 5.0 lanes per CPU feed InfiniBand/400GbE and NVMe tiers without oversubscription.
• Software-defined storage: the 20x E3.S front bay (1.2 PB flash per node) turns the 1U into an all-NVMe SDS brick – pair with Ceph/VSAN-class software for a 4U-equivalent density story.

Where the R670 Sits in the Xeon 6 Line

If the workload fits one socket and 16 Диммс, а 470 рэндов saves money; if it needs accelerators beyond 3x 75W, the R770 takes over. The R670 is the middle – the most common 1U enterprise decision point in 2026.

Configuration Advice Before You Quote

• Память: для 6400 MT/s full-speed operation, populate 1 DIMM per channel first (16 slots at 1DPC); 2DPC fills 32 slots but drops to the platform’s 2DPC speed – match density vs speed to the workload.
• E3.S media: start with Gen4 E3.S drives for the flash tier today; the Gen5 bays accept them at full Gen4 speed and leave headroom for later media upgrades.
• Boot: order the BOSS-N1 DC-MHS 960GB pair – two M.2 in hardware RAID 1 keeps boot independent of the data bays.
• блок питания: 1100W Platinum covers most builds at the 50-60% efficiency sweet spot; step to 1500W Titanium for max memory plus 20-drive configs, or DC PSUs for telco/HVDC sites.
• ввод/вывод: choose front-I/O vs rear-I/O at quote time – it changes the OCP card location and cable management, and the bezel option is front-I/O dependent.

Migration Path: R660 to R670 in Four Steps

• 1. Inventory workloads. R670 keeps the 1U density footprint – same rack slots, same rail kit class, lower weight (20.42 kg vs 22.51 кг).
• 2. Re-plan storage. E3.S Gen5 bays change media selection: budget Gen4 E3.S drives for immediate need, keep the 20-bay option open for Gen5 flash later.
• 3. Re-certify boot. BOSS-N1 DC-MHS is the same RAID-1 M.2 model – clone the boot strategy, order the 960GB variant for larger baselines.
• 4. Stagger cutover. Move the least critical 1U tier first (cloud-native / web front ends), validate telemetry through iDRAC Redfish, then scale the fleet.

Часто задаваемые вопросы о покупке

• R670 or R660? R670 for new 1U capacity on Xeon 6 (6400 МТ/с, Е3.С, Gen5, DC-MHS); R660 remains valid for legacy-fleet consistency at lower acquisition cost.
• Front I/O or rear I/O? Front I/O suits cold-aisle hot-swap service; rear I/O keeps ports away from the cold aisle for security-tight environments.
• What PSU do I need? 800/1100W Platinum for standard builds; 1500W Titanium for max-DIMM/max-drive configs; DC options (-48В постоянного тока, 240VDC/277VAC) for telco and HVDC racks.
• Can it take GPUs? Up to 3x 75W single-width accelerators – this is a density/compute 1U, not a GPU server; for accelerators see the R770 or XE9680.
• Гарантия и поддержка? Прямые цены с завода, 3-год гарантии, глобальная доставка, free configuration consultation.
• Is the R670 liquid-cooled capable? Да – the technical guide lists optional Direct Liquid Cooling (DLC) for required CPU SKUs, useful in high-density racks where 1U air cooling budget is tight.
• Can I mix E3.S and 2.5-inch bays? Нет – the bay options are mutually exclusive per backplane order. Pick the E3.S 20-bay build for all-flash density or the 2.5-inch universal build for SAS/SATA flexibility.
• What is the DC-SCM exactly? The Data Center Secured Control Module is the DC-MHS management board carrying iDRAC, the dedicated management Ethernet, and M-PESTI sideband – it is removable and common across the Xeon 6 PowerEdge family, simplifying spare-parts logistics.
