Used Dell PowerEdge R620 Technical Specifications
The refurbished Dell R620 delivers outstanding value for organizations seeking powerful, compact servers. Designed for dense rack deployments, this 1U server balances compute performance, memory capacity, and I/O scalability.
Form Factor & Platform
The used Dell R620 server features a 1U rackmount chassis, ideal for space-constrained environments that require high compute density. Its short-depth form factor ensures compatibility with standard data center racks and airflow configurations. The system supports three PCIe Gen3 slots and includes a dedicated PERC slot, enabling efficient expansion without sacrificing performance or layout integrity.
Processor Options
Each refurbished PowerEdge R620 server supports up to two Intel Xeon E5-2600 v1 or v2 processors, delivering up to 24 physical cores per system. This flexibility allows IT professionals to scale compute resources to meet application requirements, whether for virtualization clusters, middleware hosting, or parallel-processing workloads. E5 CPUs remain highly capable for many enterprise tasks in 2025.
Memory & DIMM Slot Layout
With 24 DIMM slots available, the used Dell PowerEdge R620 can be configured with up to 768GB of DDR3 RDIMM or LRDIMM, operating at speeds up to 1866 MT/s. This high memory ceiling enables smooth operation for hypervisor platforms, large in-memory databases, and scientific modeling. Dual-channel architecture ensures balanced performance across all memory banks.
Drive Bays & Internal Storage Options
Storage is flexible across multiple chassis configurations. The R620 supports 4x 3.5", 8x 2.5", or 10x 2.5" SAS, SATA, or SSD drives. Max storage capacities range from 8TB with HDDs to 38.4TB using high-density SSDs. Combined with Express Flash support and hardware RAID, the used PowerEdge R620 is well-suited for both high-speed storage and cold archival layers.

How to Choose the Right Used Dell R620 Build
Choosing the best configuration for a refurbished Dell R620 involves understanding workload types, I/O requirements, power constraints, and system redundancy strategies.
Sizing CPU & RAM for Your Workload
For environments requiring virtualization, database processing, or middleware deployment, it’s critical to match the right CPU core count with sufficient memory. A dual-CPU configuration with 128–256GB RAM is common in virtualized clusters, while single-CPU builds may suit lighter infrastructure roles. The used Dell R620 server scales well to support mixed-use workloads without overprovisioning.
Network Throughput – Onboard vs Add-On NICs
The R620 includes embedded NICs for standard Ethernet connectivity, but higher-bandwidth needs can be met with PCIe NICs, ranging from 10GbE to 40GbE. This enables flexible network design, especially in environments that use iSCSI, NAS, or software-defined networking.
Power, Cooling & Rack Depth Considerations for 1U Servers
As a 1U server, the R620 offers excellent airflow management and power efficiency. It supports redundant, hot-swappable power supplies and is optimized for standard data center rack depths. When planning deployments, consider PDU compatibility, airflow direction, and BTU output to maintain optimal thermal profiles - particularly in high-density server rooms.
Planning Spares & Redundancy Around the R620 Platform
Operational resilience depends on planning for redundancy. With a refurbished PowerEdge R620, redundancy can include dual PSUs, mirrored storage, and spare parts inventory. Alta helps you plan for fault-tolerance by offering matching spares, ensuring minimal downtime in mission-critical environments.
