Lenovo-ThinkSystem SR850 V2

Description

The Lenovo ThinkSystem SR850 V2 is a scalable enterprise server designed for organizations that need significantly more processing and memory capacity than a conventional two-socket platform can provide.

Its 2U, four-socket architecture allows the system to start with two processors and scale to four, providing a practical “pay-as-you-grow” approach for expanding enterprise infrastructure. Lenovo positions the SR850 V2 for high-volume network transaction processing, business applications, server consolidation, databases, virtualization, and growing data-center workloads.

High-Performance Intel Xeon Processing

The SR850 V2 supports 3rd Generation Intel Xeon Scalable processors, with configurations supporting two or four CPUs and processors of up to 250W TDP.

Its four-socket architecture provides substantial compute scalability for:

• Enterprise virtualization
• Large databases
• Cloud computing
• Server consolidation
• High-volume transaction processing
• Business applications
• Analytics
• Enterprise infrastructure

High-Capacity DDR4 Memory

The SR850 V2 provides up to 48 DIMM slots and supports up to 12TB of TruDDR4 memory using supported RDIMM and 3DS RDIMM configurations.

Memory speeds reach up to 3200 MT/s, and the platform also supports Intel Optane Persistent Memory 200 Series.

This large memory capacity makes the server particularly suitable for:

• Large virtual-machine environments
• In-memory databases
• Data analytics
• Enterprise applications
• Memory-intensive workloads
• High-volume transaction processing

Flexible Enterprise Storage

The SR850 V2 supports up to 24 × 2.5-inch storage drives, with support for SAS, SATA, and NVMe configurations.

It can support up to 24 NVMe drives, although the maximum direct-connect NVMe configuration depends on the selected backplane and configuration. Two 7mm drive bays can also be used for boot storage.

This makes the server suitable for both high-capacity storage and performance-sensitive applications.

RAID and Storage Controllers

The platform supports Lenovo ThinkSystem RAID and HBA adapters for enterprise storage configurations.

Supported controllers include RAID and HBA options capable of providing RAID levels such as:

• RAID 0
• RAID 1
• RAID 10

The exact RAID capabilities depend on the installed controller and storage configuration.

PCIe Expansion

The SR850 V2 supports up to eight PCIe expansion positions, with additional expansion depending on the number of installed processors.

Expansion can be used for:

• High-speed Ethernet adapters
• Fibre Channel adapters
• RAID controllers
• Storage adapters
• GPU accelerators
• Specialized PCIe devices

Some PCIe slots require four processors, making the four-socket configuration particularly valuable when maximum I/O expansion is required.

High-Speed Networking

The SR850 V2 includes a dedicated management Ethernet connection and supports an OCP 3.0 Ethernet adapter.

Supported OCP networking options include:

• 1GbE
• 10GbE
• 25GbE
• 50GbE

This provides flexibility for enterprise LAN, virtualization, storage, and high-speed data-center networking.

Enterprise Management

The SR850 V2 incorporates the Lenovo XClarity Controller (XCC) for integrated server monitoring and management.

XCC provides capabilities such as:

• Hardware monitoring
• Remote management
• Remote KVM
• Remote storage/media access
• Diagnostics
• System inventory
• Firmware management
• Hardware alerts

Lenovo also supports Redfish-based management for integration with modern infrastructure-management platforms.

High Availability and Reliability

The SR850 V2 is designed for continuous enterprise operation and incorporates multiple reliability features, including:

• Redundant fans
• Hot-swappable storage
• Redundant power supplies
• Predictive Failure Analysis
• Light Path Diagnostics
• TPM 2.0
• Enterprise RAID support

The system uses six internal dual-rotor fans with N+1 redundancy.

Redundant Power

The server supports up to two hot-swap power supplies with N+1 redundancy.

Available options include 750W, 1100W, 1800W, 2400W, and 2600W power supplies depending on configuration, with Platinum and Titanium efficiency options available.

Compact 2U Enterprise Design

Despite its four-socket architecture, the SR850 V2 uses a 2U rack form factor, allowing substantial computing capacity to be deployed without consuming the rack space of a larger 4U system.

The chassis measures approximately 86.5 mm high × 482 mm wide × 880.2 mm deep, with a maximum configuration weight of approximately 40 kg.

Ideal Applications

The Lenovo ThinkSystem SR850 V2 is ideal for:

• Enterprise virtualization
• Database servers
• Cloud infrastructure
• Server consolidation
• High-volume transaction processing
• Enterprise applications
• Business-critical workloads
• Data analytics
• Large memory applications
• Data-center infrastructure

Key Specifications

Configuration Note

The SR850 V2 is highly configurable, so the actual CPU models, RAM, storage drives, RAID controller, networking adapters, and power supplies can vary significantly between individual units.
