About Our Used Cisco UCS C240 M6 Servers

For IT managers, MSPs, resellers, and data center architects seeking high-density, enterprise-class hardware without premium OEM pricing, our used Cisco UCS C240 M6 collection offers top performance, durability, and scalability.

Professionally refurbished by Alta Technologies in supported, climate-controlled, working environments just like yours, each used UCS C240 M6 server undergoes Alta’s multi-point inspection process, component testing, and full validation.

With a global reputation built over 30 years, Alta ensures you get a refurbished C240 M6 that meets the demanding needs of virtualization, AI/ML, large-scale storage, or HPC workloads, while delivering significant cost savings compared to new.

5 Reasons to Choose a Used Cisco UCS C240 M6 Server

3rd Gen Intel Xeon CPUs for High-Performance Workloads

The Cisco UCS C240 M6 supports one or two 3rd Generation Intel Xeon Scalable processors, up to 40 cores per socket, providing strong compute capabilities for demanding tasks. Whether you’re running container orchestration, large-database clusters, or parallel compute jobs, the raw processing power gives you room to scale. Using a refurbished C240 M6 provides the same CPU architecture as an OEM-new model at a fraction of the cost.

Up to 12 TB Memory with Intel Optane Support

Memory configurations for the used UCS C240 M6 reach up to 12 TB when combining DDR4 RDIMMs and Intel Optane persistent memory modules. This allows memory-intensive applications, such as in-memory databases, real-time analytics, or virtualization with high VM density, to operate smoothly. Alta ensures each used C240 M6 rack server has fully tested memory modules and persistent memory where applicable.

Up to 28 Drive Bays with NVMe Capability

With the used Cisco UCS C240 M6 server, you can choose from multiple storage backplanes: up to 28 small-form-factor (SFF) SAS/SATA or NVMe bays in SFF models, or large-form-factor (LFF) front drives with optional rear SFF/NVMe bays in LFF configurations. NVMe support for hot-plug, front, and rear drive positions gives you ultra-low latency for cache, database, or high I/O workloads. Alta stock includes variants configured for more storage vs I/O as needed.

2U Form Factor Ideal for Dense Server Deployments

This model’s 2U form factor strikes a balance between space efficiency and thermal performance. In rack-dense environments, using used UCS C240 M6 units lets you stack high compute, memory, and storage density without sacrificing cooling or serviceability. Front IO, well-designed airflow, and redundant power options (1050 W up through 2300 W) make it versatile for both colocation and private data centers

PCIe 4.0 Expansion for Future-Proofing

Every refurbished C240 M6 server supports PCIe Gen 4.0 expansion cards via riser slots, as well as a dedicated modular LAN-on-motherboard (mLOM) slot for high-speed networking. Whether you need GPU acceleration, additional NVMe drives, or high-throughput NICs, the expansion architecture gives you the flexibility to customize for future upgrades. Alta ensures all PCIe slots are tested with loaded risers to verify stability.
