Refurbished Dell PowerEdge R720 Dual Intel Xeon E5-2640 2.50GHz Server – Enterprise-Grade Diskless Configuration
Power your data centre with the Dell PowerEdge R720, a certified refurbished dual-socket 2U rackmount server featuring dual Intel Xeon E5-2640 processors (2.50GHz, 6-core), 256GB DDR3 DIMM memory, 3 x Intel Ethernet I350 1Gb network adapters, and dual redundant 750W hot-plug power supplies. This is a diskless configuration—shipped without internal hard drives, no RAID controller, and no backplane—with a 3.5-inch large-form-factor (LFF) chassis designed to support up to 8 x 3.5-inch hot-plug drives for maximum storage capacity and flexibility. This enterprise-class server delivers exceptional performance and scalability whilst offering outstanding value through refurbished technology that has been rigorously tested and verified by Reboot IT.
Why Choose the PowerEdge R720?
The Dell PowerEdge R720 is engineered for organisations requiring a highly scalable, feature-rich server platform that handles complex workloads with ease. Setting the standard for feature flexibility in enterprise computing, this 2U rackmount solution combines powerful processing capabilities with exceptional memory capacity—256GB RAM provides exceptional headroom for virtualisation, in-memory databases, and data-intensive applications. The diskless configuration offers unparalleled flexibility, enabling deployment in network-storage environments, SAN/NAS infrastructures, and cloud-ready architectures where centralised storage management is preferred over local drives.
Practical Applications
The PowerEdge R720 diskless configuration excels across a wide range of enterprise scenarios:
-
Virtualised Environments with Centralised Storage: Leverage VMware ESXi with network boot (PXE) to host hundreds of virtual machines utilising SAN or NAS-based storage for maximum flexibility and simplified management
-
Hyper-Converged Infrastructure: Deploy as a compute node in HCI solutions where storage is managed separately or through software-defined platforms
-
Scalable Database Clusters: Host in-memory database systems (SAP HANA, Oracle RAC) with external SAN connectivity for enterprise-grade reliability and failover capability
-
Virtual Desktop Infrastructure (VDI) at Scale: Support thousands of concurrent virtual desktops with network-based boot and profile delivery
-
Cloud-Ready Computing: Perfect for containerised workloads, Kubernetes clusters, and cloud-native deployments where persistent storage is external
Key Features & Benefits
-
Dual Intel Xeon E5-2640 Processors: 12 cores of processing power (6-core per socket) with Turbo Boost technology and 15MB cache per processor for exceptional multitasking and throughput
-
Exceptional Memory Capacity: 256GB DDR3 DIMM included; purpose-built for memory-intensive enterprise applications and large-scale virtualisation

Cosmetic Grading: Excellent vs Good
Our Excellent grade servers show minimal signs of use, with only light cosmetic wear that's barely noticeable and indicates the unit has been well-maintained. Good grade units remain fully functional but display more visible cosmetic wear, such as light scratches or scuffs on the chassis, whilst maintaining identical performance specifications. Both grades are fully tested and verified—the grade reflects cosmetic condition only, not functionality.

Refurbished Computers - Cosmetic Grading Guide
Our supplier's refurbished hardware is typically graded either "Excellent" or "Good", however, some legacy products were graded under a letter grading system (A, B, C). Please find the definitions for each grade below and contact us if you're uncertain of a device's grade.
Used Smartphone / Refurbished Mobile Phones
"Excellent" Grade
Devices in this category appear like new, with very minor wear. Expect light or fine scratches on the screen that are shallow enough not to catch on a fingernail. The edge around the glass is virtually flawless, save for possible light scratching around the power port. The back plate may show light/fine scratches, including on the Apple logo, with any discoloration being minimal.
"Good" Grade
These devices are characterized by being fully tested and functional even if they have body scratches, minor paint chips, or a small hairline crack on the screen. Screens are free from dead pixels but may exhibit slight scratching from moderate use.
Refurbished Desktops, Laptops and Monitors
"Excellent" Grade - Laptops
Reserved for units that show barely any signs of previous use, these laptops may exhibit very minor scuffing or abrasions, associated only with minimal standard use. The keyboards show light wear, and importantly, the screens are pristine, free from any scratches, cracks, chips, dead pixels, dark spots, discoloration, or blemishes.
"Excellent" Grade - Desktops
Desktop PCs in the "Excellent" grade category are free from deep scratches, cracks, paint chips, or any broken/missing pieces, ensuring a sleek and almost-new aesthetic.
"Excellent" Grade - Monitors
"Excellent" grade is reserved for units that show evidence of very little to no previous use. Any wear on an "Excellent" Display, including housing/frame and/or external surfaces (i.e. Frame) is associated with standard minimal use. "Excellent" units may have minor scuffing and / or minor abrasions on plastics with from standard light previous use."Excellent" Displays will feature no scratches, cracks, chips, dead pixels, dark spots, discoloration or blemishes. Units will only feature the standard minimal wear and tear that is associated with a used unit.
"Good" Grade - Laptops
"Good" laptops may feature one or several small dings or dents on covers and / or small paint chips on the surface or small hairline cracks in the bezel. Laptop screens may feature uneven light diffusion in screen and may feature subtle blemishes. "Good" Laptops will not feature cracks screens but may feature slight scratching, dead pixels or white spots on the screen.
"Good" Grade - Desktops
