Lenovo ThinkSystem SR630 V3 Server

Ultra-Dense 1U Server Lenovo ThinkSystem SR630 V3 for Virtualization and Cloud

Lenovo ThinkSystem SR630 V3 is a flagship 2-socket enterprise-class server in an ultra-dense 1U rack form factor. The platform is a high-density alternative to the SR650 V3, optimized for space efficiency in modern data centers. The server is ideally suited for IT infrastructures with high requirements for compute power per rack unit: large-scale virtualization, cloud computing, hyperconverged infrastructure (HCI), databases, and transactional workloads (OLTP). Despite its compact 1U size, the server is built on a high-speed PCIe Gen 5.0 bus, supports DDR5 memory, and modern processors with built-in AI accelerators.

Thanks to its modular AnyBay architecture and support for the latest EDSFF drives, the SR630 V3 achieves extreme storage density and maximum IOPS in a single rack unit — critical for modern data centers where every rack unit counts.

Use Cases

The Lenovo ThinkSystem SR630 V3 is the optimal solution for organizations requiring:

• Large-scale virtualization (VMware vSphere, Microsoft Hyper-V, KVM)
• Cloud computing and private clouds
• Hyperconverged infrastructure (HCI: Nutanix, VMware vSAN)
• Databases and transactional workloads (OLTP)
• Entry-level AI inference and media stream acceleration
• Web infrastructure and high-density compute clusters
• Workloads requiring maximum compute power per rack unit

Compute Subsystem

The server supports two 4th Gen Intel Xeon Scalable (Sapphire Rapids) or 5th Gen Intel Xeon Scalable (Emerald Rapids) processors with TDP up to 350 W per socket. The architecture delivers up to 120 cores and 240 threads in a single rack unit. Built-in Intel hardware accelerators (AMX, DSA, QAT, DLB, IAA) are supported, speeding up AI inference, encryption, compression, and data streaming workloads.

Memory

The server provides 32 DIMM slots (16 per socket). It supports high-speed TruDDR5 ECC RDIMM memory at speeds up to 5600 MT/s. Maximum memory capacity is 4 TB (with standard 128 GB modules) or up to 8 TB (using specialized 256 GB 3DS RDIMM modules). This memory capacity allows consolidating workloads onto a single 1U server that previously required larger platforms.

Drive Bay Configuration

The modular AnyBay architecture provides flexible front-panel configurations for hot-swap drives:

• Up to 10 × 2.5″ (SFF) SAS/SATA/NVMe SSDs
• Up to 4 × 3.5″ (LFF) SAS/SATA (HDD/SSD) drives for cost-effective, high-capacity local storage
• Up to 16 × EDSFF (E1.S / E3.S) NVMe PCIe Gen5 drives for extreme density and maximum IOPS
• OS Boot: internal dual-drive M.2 module with hardware RAID 1 mirroring, or up to two hot-swap 7mm rear drives

The AnyBay configuration allows mixing NVMe, SAS, and SATA in the same bays, adapting the server to changing workload profiles without chassis replacement.

Graphics Accelerators (GPU)

Thanks to its dense 1U layout, the server supports up to 3 compact single-wide GPUs (up to 75 W, such as NVIDIA L4) for entry-level AI inference and media stream acceleration. This makes the SR630 V3 suitable for video analytics, transcoding, and inference workloads without moving to larger platforms.

Expansion Slots

Depending on the riser card configuration, the server provides up to 3 PCIe slots, of which up to two are PCIe Gen5 x16. Additionally, a dedicated OCP 3.0 Gen5 slot is provided for network cards (up to 100/200 GbE) without consuming standard expansion lanes. This allows simultaneous installation of GPU accelerators, RAID controllers, and high-speed network adapters.

Reliability, Security, and Management

• Remote Management. Monitoring, diagnostics, and deployment are handled by the embedded Lenovo XClarity Controller 2 (XCC2) service processor with an intuitive web interface and Redfish REST API support. Integration with XClarity Administrator and the XClarity One cloud platform simplifies server fleet management.
• Power and Cooling. The server is equipped with two redundant hot-swap power supplies rated at 750 W, 1100 W, 1800 W, or 2400 W with Platinum/Titanium certification. Cooling is provided by 7 compact hot-swappable fans with N+1 redundancy. When installing processors with TDP > 165 W, Performance fans are used.
• Hardware Security. The ThinkShield suite provides physical and firmware-level security: TPM 2.0 crypto chip, Platform Firmware Resiliency (PFR) firmware control and recovery compliant with NIST SP 800-193, and a chassis intrusion sensor.
