Description

Empower your enterprise infrastructure with the robust and versatile Lenovo ThinkSystem SR650. This specific configuration is engineered for environments that demand high clock speeds and reliability. At the core are dual Intel Xeon Platinum 8268 processors. These are top-tier Cascade Lake CPUs, each offering 24 cores and a high base frequency of 2.9GHz with a 205W TDP. With 48 physical cores and 96 threads combined, this server delivers exceptional throughput for mission-critical applications that benefit from both high core counts and fast single-thread performance.

To support memory-intensive workloads, this unit is outfitted as a 768GB RAM Server. The massive memory footprint allows you to run large in-memory databases or host a high density of virtual machines without paging to disk. For storage, the system balances capacity and cost-efficiency with four 1.8TB 10K SAS HDD drives. These enterprise-grade spinning disks provide reliable mass storage for data archiving, backup targets, or transactional databases where the cost-per-GB of SSDs is prohibitive. Data integrity is further assured by the RAID 730-8i controller, which features 2GB of flash-backed cache and a SuperCap, protecting your write cache in the event of a power loss.

Connectivity is a major strength of this configuration. It features a QLogic QLE2742 Dual-Port 32Gb Fibre Channel HBA, enabling ultra-low latency connections to external storage arrays (SAN). This is complemented by a robust Ethernet networking setup consisting of two Intel X710-DA2 adapters, providing a total of four 10GbE SFP+ ports for high-speed data traffic, plus a standard 1Gb RJ45 adapter for management. This diverse I/O capability makes the server a central hub for complex network topologies.

Reliability extends to the power architecture, with dual 1100W redundant hot-swap power supplies ensuring the high-performance CPUs receive stable power even during a circuit failure. When you Buy Lenovo SR650, you are investing in a 2U Rackmount Server known for its serviceability and thermal design. Included rack rails and SFP+ transceivers make deployment straightforward, allowing IT teams to integrate this powerhouse into their data center with minimal setup time.

Key Features

  • High-Frequency Compute: 2x Intel Xeon Platinum 8268 CPUs (2.9GHz Base, 24 Cores/48 Threads each) for peak performance.
  • Massive Memory Capacity: 768GB DDR4-2933 ECC RDIMM ensures smooth multitasking and virtualization.
  • Reliable Storage: 4x 1.8TB 10K SAS HDDs offer significant capacity with enterprise reliability.
  • Advanced RAID: RAID 730-8i with 2GB Flash and SuperCap backup protects data during power failures.
  • SAN Ready: QLogic Dual-Port 32Gb Fibre Channel HBA for high-speed external storage connectivity.
  • Robust Networking: 4x 10GbE SFP+ ports (via 2x Intel X710-DA2) plus 1Gb RJ45 management port.
  • Power Redundancy: Dual 1100W Hot-Swap PSUs handle high-wattage components safely.
  • Complete Kit: Includes Rack Rails and 4x SFP+ SR Transceivers.

Configuration

Component Specification

Compatibility

The Lenovo ThinkSystem SR650 is a versatile platform compatible with industry-standard operating systems such as Windows Server 2019/2022, Red Hat Enterprise Linux (RHEL) 7/8/9, and SUSE Linux Enterprise Server. It is also fully certified for virtualization platforms like VMware vSphere 7.0 and 8.0. The QLogic 32Gb FC HBA is backward compatible with 16Gb and 8Gb SAN infrastructures. The chassis supports standard 2.5-inch SAS and SATA drives, allowing for future expansion or replacement with SSDs if performance needs change.

Usage Scenarios

This server is an excellent choice as an Enterprise Database Server. The Intel Xeon Platinum 8268 processors provide high clock speeds which directly benefit licensing costs and query execution times in databases like Oracle or SQL Server. The 1.8TB 10K SAS drives provide a cost-effective storage tier for massive transactional logs or data warehouses that do not require the expense of all-flash arrays.

For organizations utilizing a Storage Area Network (SAN), this unit serves as a powerful SAN-Attached Compute Node. The 32Gb Fibre Channel HBA allows the server to boot from or access shared storage on an external array with minimal latency. This makes it ideal for clustered environments where data must remain accessible even if the compute hardware is serviced.

The system is also configured for High-Density Virtualization. With 768GB of RAM and 48 physical cores, it can host a significant number of virtual machines. The inclusion of redundant 10GbE uplinks ensures that network traffic from these VMs is not bottlenecked, while the SuperCap-backed RAID controller ensures that VM data in transit is safe during power anomalies.

Lastly, this configuration is suitable for Big Data Analytics where memory capacity is key. The 768GB RAM Server capacity allows for large datasets to be loaded into memory for processing by applications like Apache Spark, while the SAS HDDs provide local scratch space for intermediate results.

Frequently Asked Questions

Q: What is the benefit of the SuperCap on the RAID controller?
A: The RAID 730-8i adapter includes a 2GB Flash cache. The SuperCap (Super Capacitor) provides temporary power to write the contents of this cache to non-volatile flash memory in the event of a sudden power loss. This prevents data corruption and ensures that unwritten data is saved and written to disk once power is restored.

Q: Why use 10K SAS HDDs instead of SSDs?
A: 10K SAS HDD drives offer a balance between performance and cost. While slower than SSDs, they provide reliable enterprise performance at a much lower cost per gigabyte, making them ideal for bulk storage, backup targets, or applications where maximum IOPS are not the primary constraint.

Q: Can I upgrade the networking speed later?
A: Yes, the Lenovo SR650 features multiple PCIe slots. You can replace the existing 10GbE cards with 25GbE or even 100GbE adapters in the future. Similarly, the Fibre Channel card can be swapped or removed if your storage infrastructure changes.

Q: Is the 1100W PSU necessary?
A: Yes. The Intel Xeon Platinum 8268 processors consume up to 205W each. When combined with nearly 1TB of RAM, PCIe cards, and spinning hard drives, the power draw is substantial. The 1100W PSUs ensure the system remains stable under full load and provide the necessary redundancy.
