Dell PowerEdge R4715 and R5715 function as a unified configurable server matrix, covering two chassis styles, four AMD EPYC 9005 Series CPUs, diverse storage options, and a full Dell management and support ecosystem. Tailored for SMBs and channel partners, the platform allows infrastructure deployment to be precisely aligned with actual workload demands. Both models launched in March 2026; this guide analyzes their combined workload performance and configuration value, rather than evaluating each server independently.
Flexible hypervisor support is a core advantage for modern SMB IT environments. The two servers are compatible with mainstream virtualization platforms including VMware ESXi, Microsoft Hyper-V, Proxmox VE and Linux KVM distributions, delivering consistent deployment and management across hypervisor choices. This adaptability benefits SMBs running multiple virtualization stacks and eliminates single-platform lock-in, prompting multi-hypervisor testing in this review.
Dell Ecosystem Advantages for SMBs & Channel Partners
While server silicon specifications are critical, operational usability determines long-term value for lean SMB IT teams and value-added resellers (VARs). Dell’s mature 17th-gen PowerEdge ecosystem delivers unified tooling, robust security and reliable supply chain support that greatly reduces operational overhead.
The unified iDRAC10 and OpenManage Enterprise management plane applies to all 17th-gen PowerEdge devices. SMBs can expand their server fleet with other PowerEdge models without learning new management tools, while VARs can uniformly manage all customer server infrastructure. The platform supports remote console access, firmware updates, hardware health monitoring and Redfish API automation, minimizing on-site maintenance and partner intervention frequency.
Standard enterprise-grade security includes silicon root of trust, signed firmware, component verification and FIPS-certified TPM 2.0. Global ProSupport and ProDeploy services, alongside predictable large-scale supply chain lead times, help partners avoid delivery delays and stabilize project delivery, forming a key competitive edge for SMB-oriented deployments.
R4715 & R5715 Overview
The R4715 is a 1U single-socket server optimized for high compute density. It supports 24 DDR5 RDIMMs, three PCIe Gen5 slots, and flexible storage configurations including 2.5/3.5-inch SAS/SATA and 8-bay U.2 NVMe, ideal for rack-dense deployments prioritizing compute over drive quantity.
The R5715 is a 2U single-socket model focused on storage capacity and I/O expandability. It shares the same 24 DDR5 memory support and four CPU options as the R4715, adding a fourth PCIe Gen5 slot. It supports 12×3.5-inch or 16×2.5-inch drive bays, reaching up to 288TB raw storage with 3.5-inch HDDs.
Both servers adopt air cooling, integrate iDRAC10, and support 800W/1100W Platinum/Titanium power supplies. They exclude GPU, DPU and Fibre Channel support, positioning them as right-sized SMB platforms rather than fully expandable high-end servers. Dell’s product tiering enables seamless upgrades to higher-spec R6715/R7715 models for users needing more cores or accelerators, with consistent management and support workflows.

Four AMD EPYC 9005 CPU Options
Dell’s four Zen 5 CPU SKUs cover all mainstream SMB workloads without redundant specifications, sharing identical platform memory and PCIe capabilities to eliminate configuration restrictions. Core count selection directly reduces recurring per-core licensing costs for Windows Server, databases and virtualization platforms.

The 32-core 9335 delivers maximum compute flexibility; the 24-core 9255 offers optimal price-performance for database workloads; the 16-core 9135 matches Windows Server’s minimum licensing core requirement; the 8-core 9015 is a low-cost, low-power option for storage-centric workloads.
Performance Testing
Test platform: Both servers equipped with 384GB DDR5 and BOSS RAID1 boot storage. R4715 used 8×1.92TB Samsung PM9D3a NVMe SSDs (RAID10); R5715 used 12×20TB HDDs (RAID6), tested with EPYC 9015.
Database Workload (HammerDB MariaDB TPC-C)
R4715 flash storage delivers smooth CPU performance scaling across all four processors. The 8-core 9015 hit 480,818 NOPM (CPU-intensive) and 296,105 NOPM (I/O-intensive). The 16-core 9135 saw a major performance jump to 737,445 / 493,093 NOPM. The 24-core 9255 broke 1 million NOPM (1,017,429 CPU / 740,574 I/O), while the 32-core 9335 topped out at 1,133,714 / 910,321 NOPM with no storage bottlenecks.
R5715 HDD configuration with 9015 peaked at 484,715 NOPM (CPU-intensive) and 308,012 NOPM (I/O-intensive). Spinning disk performance scaled well under moderate concurrency but saturated quickly with heavy concurrent database loads.
Windows Server Shared Storage (FIO Benchmark)
The two storage tiers show massive performance gaps. R5715’s RAID6 HDD array delivers solid sequential throughput (3.7GB/s write / 2.2GB/s read) for file serving and bulk storage, but suffers high latency and low random IOPS. R4715’s all-flash configuration achieves 56GB/s+ reads and 26GB/s+ writes, with 4K random IOPS exceeding 4 million and sub-millisecond latency, perfectly suited for multi-user file shares and VM workloads.
Proxmox Backup Server Deployment
R5715 with 8-core 9015 and high-capacity HDDs is ideal for virtualized backup targets. Tested with Proxmox Backup Server 4.2.0, backup/restore performance was limited by baseline 1GbE networking. Upgradable OCP network cards support 10GbE/25GbE, enabling drastically higher throughput for large-scale backup workloads.
Conclusion
Dell R4715 and R5715 form a well-structured SMB server matrix with clear functional differentiation: R4715 for high-density all-flash compute workloads, R5715 for high-capacity bulk storage scenarios. The four CPU options precisely match diverse SMB workloads, avoiding over-provisioning and reducing hardware and licensing costs.
Backed by Dell’s unified management, comprehensive security, global support and stable supply chain, the platforms lower operational difficulty for lean IT teams and channel partners. Designed for workload right-sizing and infrastructure consolidation, the R4715/R5715 series delivers outstanding targeted value for small and medium business deployments.
