Dell PowerEdge R6515 1U Rack Server

The Dell PowerEdge R6515 is a 15th Generation single-socket 1U rack server powered by AMD EPYC 7002/7003 (Rome/Milan) processors with up to 64 cores in a single socket. It delivers dual-socket-class core counts at single-socket licensing costs, making it the most cost-effective option for per-core software licensing models used by VMware, Oracle, and SQL Server.

Enterasource offers the R6515 in multiple chassis configurations including 10x2.5-inch SFF and 4x3.5-inch LFF. Each server is built to order, tested through our multi-point hardware diagnostic process, and backed by a 2-year Enterasource warranty.

With 128 PCIe Gen 4 lanes from a single EPYC socket, 16 DDR4 DIMM slots supporting up to 2 TB of memory, and iDRAC9 management, the R6515 provides high-density compute for virtualization, cloud-native applications, and HPC workloads where single-socket licensing savings are a priority.

Dell R6515 vs R650 — AMD Single-Socket vs Intel Dual-Socket 1U

Feature	R6515 (AMD 1S)	R650 (Intel 2S)
Sockets	1	2
Max Cores	64	80
PCIe Lanes	128 Gen 4	128 Gen 4 (64/CPU)

Power Consumption	Lower	Higher

Choose the R6515 when single-socket licensing savings outweigh the need for 80 cores and 32 DIMM slots. AMD EPYC provides 128 PCIe Gen 4 lanes from one socket — matching Intel total across two sockets. Choose the R650 when you need more than 64 cores, 32 DIMM slots, or Intel Optane PMem.

Frequently Asked Questions

What processor does the Dell R6515 use?

The R6515 uses a single AMD EPYC 7002 (Rome) or 7003 (Milan) processor with up to 64 cores and 128 threads.

What generation is the Dell R6515?

The Dell PowerEdge R6515 is a 15th Generation (15G) server. The predecessor is the R6415 (14G); the successor is the R6615 (16G, AMD EPYC 9004 with up to 128 cores).

Why choose the R6515 over a dual-socket Intel server?

The R6515 delivers 64 cores from a single socket, reducing per-core software licensing costs for VMware, Oracle, SQL Server, and other per-socket or per-core licensed software. AMD EPYC also provides 128 PCIe Gen 4 lanes from one socket, matching Intel dual-socket total.

Is the Dell R6515 a good Proxmox VE host?

Yes, and the licensing math is better than on any dual-socket alternative. Proxmox VE is licensed per physical CPU socket with no per-core, per-VM or per-user fees, so a single-socket R6515 running a 64-core EPYC 7002 or 7003 needs exactly one subscription — the same 64 cores split across two Intel sockets would need two. On the hardware side, AMD EPYC exposes AMD-V and AMD-Vi (IOMMU) as standard on PowerEdge, so KVM/QEMU virtualization and clean PCIe passthrough both work out of the box, and 128 Gen 4 lanes from a single socket mean an NVMe pool, 25 GbE networking and a passthrough GPU can coexist without contending across a socket interconnect. Sixteen DIMM slots take up to 1 TB of RDIMM or 2 TB of LRDIMM, which is ample for a dense single-node PVE host or a ZFS pool with a large ARC. Enterasource is an authorized Proxmox reseller: VE, Proxmox Backup Server and support are quoted with the server.

How much does a refurbished Dell R6515 cost?

Pricing depends on processor, memory, and storage configuration. Enterasource builds every R6515 to order with a 2-year warranty and free ground shipping to the lower 48 states.
