Dell PowerEdge R7725xd
What Is the Dell PowerEdge R7725xd?
The R7725xd is the storage-optimized (“xd” — extreme density) dual-CPU member of Dell’s 17th-generation PowerEdge family on AMD’s EPYC 9005 “Turin” (Zen 5) platform. Two SP5 processors provide 24 DDR5 channels and, with the Turin-Dense parts, up to 192 cores per socket for a system maximum of 384 cores — ample compute to drive storage software, data services and east-west replication rather than to host accelerators. Dell launched the R7725xd in 2025 alongside the general-purpose R7725 and the 1U R6715/R6725, succeeding the 16th-generation storage line.
The 2U chassis is built around flash: 24 front 2.5″ U.2 PCIe Gen5 NVMe bays or 40 front E3.S/E3.L PCIe Gen5 NVMe bays, up to five PCIe Gen5 x16 slots and one OCP 3.0 connection for high-speed storage networking. Two design decisions define the xd: there is no internal GPU support and no internal hardware RAID controller. Every drive is presented directly to the operating system or hypervisor — the passthrough, JBOD-style topology that Ceph, vSAN, ZFS and object-storage platforms expect. iDRAC10 management and Quick Sync 2 wireless provisioning are included. It is a current platform: parts, firmware and warranty support are all first-line.
Condition: new or graded refurbished, with the condition grade stated per unit on every quote line. Read what New Old Stock means and our 3-year warranty terms.
Why Choose the R7725xd for All-Flash Storage?
The R7725xd is not a general-purpose server with extra disks — it is engineered around the storage path. Choose it when the workload is flash throughput and data services rather than accelerator compute:
- 24 Gen5 NVMe drives in 2U. Twenty-four U.2 or up to forty E3.S/E3.L hot-pluggable PCIe Gen5 NVMe devices in a single dual-socket node give Ceph, vSAN and object storage tens of high-IOPS, low-latency failure domains without SAS expanders or a hardware RAID layer.
- Passthrough by design, no internal RAID. With no internal RAID controller in the data path, every NVMe device is visible and manageable directly by your software-defined storage stack — replica placement, erasure coding and rebuilds stay under cluster control, and there is no proprietary RAID volume to migrate or troubleshoot.
- Dual Turin bandwidth behind the disks. Up to 384 Zen 5 cores, 24 DDR5-6400 channels and one OCP 3.0 connection feed the checksum, compression, encryption and replication work that all-flash clusters demand, including 100/200/400 GbE storage fabrics.
If you need GPUs, hardware RAID or a wider mix of drive formats, the general-purpose R7725 supports up to 40 E3.S bays, internal accelerators and PERC H965i/H975i controllers. Choose the R7725xd for software-defined, distributed and hyperconverged storage where disks pass through untouched.
Where the R7725xd Fits
All-flash software-defined storage
Twenty-four Gen5 NVMe drives in passthrough make a dense Ceph, ZFS or Storage Spaces Direct node with every device exposed directly to the storage daemons.
HCI & vSAN clusters
Dual Turin CPUs, 24 DDR5-6400 DIMMs and 24 flash devices run vSAN and hyperconverged clusters that need local NVMe capacity and storage-policy control rather than hardware RAID.
Distributed & object storage, data lakes
OCP 3.0 high-speed networking and 24 U.2 or 40 E3.S hot-pluggable NVMe bays suit object stores, distributed file systems and data-lake nodes built on replication or erasure coding.
High-density NVMe storage nodes
Proxmox VE, backup-to-flash targets and private-cloud storage tiers get maximum flash density per 2U rack unit with iDRAC10 fleet management and Quick Sync 2 provisioning.

R7725xd Specifications in Detail
Processor. Two AMD EPYC 9005 Series (Turin / Turin-Dense) in SP5 sockets, up to 192 cores per socket and 384 cores in total. On an xd node the dual CPUs run storage software, data services and tenant VMs side by side; the exact SKU, core count, frequency and cTDP are built to your workload and confirmed on the order and inspection report.
Memory. 24 × DDR5 RDIMM across 24 channels (12 per socket) at 6400 MT/s, up to 3 TB*. Multi-unit orders ship with matched, identical DIMM layouts for uniform clusters.
Storage. The front of the chassis offers either 24 × 2.5″ U.2 PCIe Gen5 NVMe bays or 40 × E3.S / E3.L PCIe Gen5 NVMe bays — an all-flash, Gen5 end-to-end configuration. The chassis is front-only for data drives: there are no rear drive bays on the R7725xd. There is no hardware RAID layer: the node feeds raw NVMe devices directly to distributed storage software.
Expansion & GPUs. Up to five PCIe Gen5 x16 slots plus one OCP 3.0 connection provide the lanes for storage fabrics and adapters. Internal GPUs are not supported on the R7725xd — if your workload needs accelerators, the general-purpose R7725 is the correct 17G platform.
Controllers & management. The R7725xd ships without an internal RAID controller; drives operate passthrough-style and redundancy — replication or erasure coding — is delivered by Ceph, vSAN, ZFS or the chosen SDS stack. iDRAC10 provides remote lifecycle management and telemetry; Quick Sync 2 enables wireless rack-side provisioning and inventory.
R7725xd vs R7725 and R7625xd
The three names are easy to confuse. The R7725xd and the R7725 are both 17th-gen Turin servers in the same 2U family — but the xd is a purpose-built all-flash storage node (no GPU, no internal RAID), while the R7725 is the flexible general-purpose flagship. The R7625xd is the previous 16th-generation storage-focused dual-socket 2U model on EPYC 9004 (Genoa/Zen 4).

R7625xd details vary by chassis backplane and controller configuration; the model name is given for generation comparison only and exact build options are confirmed per order.
R7725xd vs R7725: the xd gives up the general-purpose extras on purpose — no internal GPU, no PERC RAID, and a fixed 24-bay U.2 or 40-bay E3.S all-flash front (versus up to 40 E3.S on the R7725) — in exchange for a clean passthrough storage topology. Pick the xd when Ceph, vSAN or an object store owns disk redundancy; pick the R7725 when you want one platform to cover databases, virtualization and accelerators.
R7725xd vs R7625xd: stepping up from 16G brings Zen 5 Turin compute (up to 384 cores), DDR5-6400, end-to-end PCIe Gen5 NVMe, iDRAC10 and the longest current support runway — a meaningful jump for storage clusters that run for five or more years.

Frequently Asked Questions
What is the Dell PowerEdge R7725xd?
The Dell PowerEdge R7725xd is Dell’s 17th-generation dual-socket 2U storage-dense (xd) all-flash server on two AMD EPYC 9005 “Turin” (Zen 5) CPUs, launched in 2025. It supports up to 192 cores per socket and 384 cores in total, 24 DDR5-6400 DIMMs up to 3 TB*, 24 front 2.5″ U.2 PCIe Gen5 NVMe or 40 front E3.S/E3.L Gen5 NVMe drives, up to five PCIe Gen5 x16 slots and one OCP 3.0 connection. It has no internal GPU support and no internal RAID controller, and is designed for Ceph, vSAN, Proxmox and object storage. We supply it new or graded refurbished, with the condition grade stated per unit on every quote line; new units ship factory-sealed with a 3-year warranty.
What is the difference between the R7725xd and the R7725?
Both are 17th-gen dual-socket 2U Turin servers, but they have different jobs. The R7725 is the general-purpose flagship: up to 40 E3.S Gen5 drives, up to 6 TB of memory, up to two double-width plus six single-width GPUs and PERC H965i/H975i hardware RAID. The R7725xd is a purpose-built all-flash storage node: 24 front U.2 or E3.S Gen5 NVMe bays, up to 3 TB* memory, no internal GPU and no internal RAID controller, so drives pass straight through to software-defined storage. Choose the xd for Ceph, vSAN and object storage; choose the R7725 for mixed virtualization, databases and accelerator workloads.
Does the R7725xd support GPUs?
No. The R7725xd does not support internal GPUs — the chassis and riser design are dedicated to the 24-bay all-flash storage layout. Its up to five PCIe Gen5 x16 slots and one OCP 3.0 connection are intended for storage adapters and high-speed networking rather than accelerators. If you need internal GPUs in a 17th-gen dual-socket 2U Turin platform, the general-purpose R7725 supports up to two double-width plus six single-width cards.
Does the R7725xd include a hardware RAID controller?
No. The R7725xd ships without an internal RAID controller by design. NVMe drives are presented in passthrough / JBOD style directly to the operating system or hypervisor, and redundancy is delivered by the software-defined storage layer — for example Ceph replication or erasure coding, vSAN storage policies, or ZFS mirrors/RAID-Z. This avoids a proprietary RAID volume in the data path and is the standard topology for distributed all-flash clusters.
What storage does the R7725xd support — how many NVMe drives?
The front of the chassis is offered in two all-flash layouts: 24 × 2.5″ U.2 PCIe Gen5 NVMe bays, or 40 × E3.S / E3.L PCIe Gen5 NVMe bays — a maximum of 40 front Gen5 NVMe devices. There are no rear drive bays: all data drives sit in the front all-flash rows. All front drives are PCIe Gen5 NVMe; the node is not built for spinning media or hardware RAID arrays.
R7725xd vs R7625xd — is the 17th-generation upgrade worth it?
The R7625xd is the 16th-generation storage-focused dual-socket 2U server on EPYC 9004 (Genoa/Zen 4). The R7725xd moves to Zen 5 Turin with up to 192 cores per socket and 384 cores in total, DDR5-6400 across 24 channels, PCIe Gen5 NVMe from end to end (24 U.2 or 40 E3.S/E3.L drives), the passthrough SDS topology and iDRAC10 with Quick Sync 2. For new all-flash clusters, the R7725xd gives the current platform, Gen5 flash bandwidth and the longest support runway; exact R7625xd options vary by configuration.
Is the R7725xd new, what is the warranty and how do I order?
The R7725xd we supply is new or graded refurbished, current production, with the condition grade stated per unit on every quote line; new units ship factory-sealed with a 3-year warranty. Each build is assembled, BIOS/iDRAC/firmware-baselined and stress-tested across CPU, memory and all 24 NVMe bays before dispatch, and ships with an inspection report. Send your target configuration (CPU SKU and cores, RAM, U.2 or E3.S backplane, networking, quantity), destination and incoterm and we reply within one business day with a configured build, firm channel price and lead time. Full terms are on the warranty page.
