The R750XA-BASE is a 2U dual-socket server built for the 3rd Gen Intel Xeon Scalable (Ice Lake) processor family. This form factor and socket combination sits at the core of most modern data-centre refresh conversations: you get sufficient density for rack-constrained environments while retaining the thermal headroom and upgrade flexibility that mission-critical infrastructure demands. Dell engineered the R750xa to handle workloads ranging from virtualisation and database consolidation through to GPU-accelerated AI training and high-performance computing, making it one of the most versatile platforms in the current generation.

Memory capacity is where the R750xa distinguishes itself in its segment. The platform supports up to 32 DIMM slots and can accommodate 8 TB of total addressable memory when Intel Optane persistent memory (PMem 200 series) is deployed alongside DDR4, or 4 TB using DDR4 3200 MT/s RDIMM, LRDIMM, and 3DS RDIMM configurations alone. For infrastructure architects planning large-scale virtualisation, in-memory databases, or analytics workloads, this memory envelope eliminates the need to shard across multiple nodes for many use cases. The flexibility to mix memory types within a single chassis is equally valuable: you can tier your memory hierarchy, placing hot working sets in DDR4 and persistent datasets in PMem without requiring separate hardware.

GPU support on the Dell R750xa accommodates up to four double-width PCIe graphics accelerators—NVIDIA A30, A100, or H100 PCIe, or AMD Instinct devices—backed by three PCIe 4.0 x16 slots plus additional riser card options. Storage infrastructure includes 24 drive bays for 2.5-inch NVMe, SAS, or SATA drives, plus two rear-mounted 2.5-inch slots, all controlled via Dell's PERC H755 12 Gb SAS RAID controller (with HBA355i or PERC H345 alternatives available). Boot is handled by the BOSS-S2 M.2 card, which mirrors two NVMe or SATA drives for subsecond failover in production environments. An AI infrastructure team evaluating this platform will find the PCIe lanes and GPU thermal design work immediately familiar; a storage architect will appreciate the per-drive fault domains and controller redundancy options; a virtualisation administrator will recognise the memory and processor scaling as directly proportional to VM density.

Networking flexibility is integral to the R750xa's role in modern data centres. The platform ships with four 1 GbE Broadcom LOM interfaces as standard, but OCP 3.0 mezzanine slots support 25 GbE and 100 GbE network cards—Mellanox ConnectX-6 or Broadcom 57414 options are common. This matters for organisations transitioning away from legacy 1 GbE infrastructure or consolidating multiple physical servers into fewer, larger nodes that require fat-pipe uplinks. Power delivery scales from dual 800W Titanium supplies in entry configurations through 1400W and 2400W redundant PSUs for GPU-heavy or peak-utilisation scenarios, keeping the 2U form factor thermally manageable even under sustained load. Dell's iDRAC9 Enterprise or Datacenter management interface, combined with OpenManage Enterprise and Redfish API access, ensures that provisioning, monitoring, and remediation integrate cleanly into existing toolchains—whether you are running Kubernetes clusters, vSphere estates, or bare-metal HPC environments.

The R750xa part number R750XA-BASE qualifies for all current-generation Red Hat Enterprise Linux (RHEL 8/9), SUSE Linux Enterprise Server 15, Ubuntu 20.04/22.04, Windows Server 2019/2022, and VMware vSphere 7/8 certification paths. Security posture includes iDRAC9 Secure Boot, cryptographically signed firmware, Silicon Root of Trust, and TPM 2.0 compliance—requirements that are now table-stakes for enterprises in regulated sectors or those managing multi-tenant cloud infrastructures. At roughly 27.2 kg fully loaded and spanning 3.44 by 48.24 by 71.12 cm (height by width by depth), the R750xa occupies a single 2U slice in your rack, leaving room for switch fabric, power distribution, and monitoring equipment on the remaining U's in a standard 42U cabinet.

GPU, Memory, and Storage Tier Positioning

• Dual 3rd Gen Intel Xeon Scalable sockets with up to 40 cores per processor (80 total), paired with 32 DIMM slots supporting 8 TB memory (with Intel PMem) for memory-bound virtualisation, analytics, and database consolidation
• Four double-width PCIe GPU slots enabling NVIDIA A30/A100/H100 or AMD Instinct accelerators, ideal for machine learning training, inference, and HPC applications requiring sub-microsecond fabric latency
• 24 x 2.5-inch hot-plug drive bays with PERC H755 12 Gb SAS RAID controller and BOSS-S2 mirrored M.2 boot option, supporting mixed NVMe/SAS/SATA tier strategies without multi-chassis sprawl
• OCP 3.0 25 GbE / 100 GbE network mezzanine support alongside four embedded 1 GbE ports, addressing both legacy brownfield infrastructure and next-generation fabric consolidation
• Redundant hot-plug Titanium-rated power supplies (800W/1400W/2400W options) and GPU-optimized cooling pathways, reducing operational MTTR and thermal cycling stress in 24/7 data-centre environments
• iDRAC9 Enterprise Secure Boot, Silicon Root of Trust, and Redfish API for inventory, patching, and incident response automation across heterogeneous multi-vendor estates
