Description

Optimize your critical business workloads with this performance-tuned Lenovo ThinkSystem SR650 configuration. Designed for applications that demand high clock speeds, this server features dual Intel Xeon Gold 6136 processors. Unlike standard processors that prioritize core count over speed, the Gold 6136 offers a high base frequency of 3.0GHz across 12 cores per socket. This makes it an exceptional High Frequency Server solution, ideal for per-core licensed software like Oracle or Microsoft SQL Server, where maximizing performance per licensed core reduces overall operational costs.

Supporting this high-speed compute engine is a substantial 512GB RAM Server memory configuration. Using robust DDR4-2666 ECC LRDIMMs, the system provides the bandwidth and capacity necessary to handle large in-memory datasets and dense virtualization environments without bottlenecks. The storage tier utilizes four 1.8TB SAS Storage Server drives (10K RPM), offering a reliable and cost-effective solution for data persistence. This storage is managed by the ThinkSystem RAID 730-8i controller, which includes 2GB of flash cache and SuperCap backup protection to ensure data integrity during power interruptions.

For connectivity, this unit is built to integrate seamlessly into modern enterprise storage networks. It includes a QLogic QLE2742 Dual-Port 32Gb Fibre Channel HBA, enabling ultra-low latency connections to high-performance Storage Area Networks (SAN). This is complemented by a powerful Ethernet setup featuring two Intel X710-DA2 adapters, providing four 10GbE SFP+ ports for fast VM migration and data traffic, alongside a standard 1Gb RJ45 adapter for management. The inclusion of four SFP+ SR transceivers means the networking is ready to deploy immediately.

Reliability is paramount in this enterprise-grade hardware. The chassis is powered by dual 1100W redundant hot-swap power supplies, ensuring sufficient headroom for the high-wattage 145W processors and peripheral cards. When you Buy Lenovo SR650, you receive a complete package including rack rails for easy installation into standard data center racks. This Enterprise Database Server offers the perfect balance of compute speed, memory density, and I/O flexibility to drive your business forward.

Key Features

  • High Clock Speed: 2x Intel Xeon Gold 6136 processors (3.0GHz Base, 12 Cores/24 Threads each) optimized for single-thread performance.
  • Large Memory Capacity: 512GB of DDR4-2666 ECC LRDIMM memory for memory-intensive applications.
  • SAN Connectivity: QLogic QLE2742 Dual-Port 32Gb Fibre Channel HBA for high-speed external storage access.
  • Robust Networking: 4x 10GbE SFP+ ports (via 2x Intel X710-DA2) and 1x 1Gb RJ45 management port.
  • Data Protection: RAID 730-8i adapter with 2GB Flash and SuperCap backup.
  • Reliable Storage: 4x 1.8TB 10K SAS HDDs for consistent enterprise performance.
  • Redundant Power: Dual 1100W Hot-Swap PSUs to support high-performance components.
  • Deployment Ready: Includes 4x SFP+ SR transceivers and rack mounting rails.

Compatibility

The Lenovo ThinkSystem SR650 supports a wide array of enterprise software. It is certified for Microsoft Windows Server 2016, 2019, and 2022, making it a stable platform for Windows-based applications. It also fully supports VMware vSphere 6.5 through 8.0, allowing for seamless integration into virtualized clusters. The QLogic 32Gb FC HBA is compatible with major storage array vendors such as NetApp, Dell EMC PowerStore, and HPE Primera, and supports auto-negotiation to 16Gb and 8Gb speeds for legacy SAN switches.

Usage Scenarios

This server is specifically tailored for High-Performance Database Hosting. The Intel Xeon Gold 6136 processors running at 3.0GHz significantly reduce query response times for databases like SQL Server and Oracle. Since these databases are often licensed by core count, having fewer, faster cores provides better performance value per license dollar compared to high-core-count, low-frequency CPUs.

As a SAN-Attached Virtualization Node, the system excels in environments using shared storage. The 32Gb Fibre Channel connection allows virtual machines to access data on an external All-Flash Array with near-native speeds. The 512GB of RAM allows for high consolidation ratios, letting you run many VMs on a single host without memory contention.

The configuration is also suitable for Financial Trading Platforms. In High-Frequency Trading (HFT), every millisecond counts. The high base clock of the CPU combined with the low-latency 10GbE networking ensures that trade execution instructions are processed and transmitted with minimal delay.

Finally, it serves as a robust Exchange or Email Server. The internal 1.8TB 10K SAS drives provide ample local storage for mail stores and logs, while the RAID controller with battery backup ensures that no transaction logs are lost in the event of a facility power failure.

Frequently Asked Questions

Q: Why choose the Gold 6136 over a Gold 6140?
A: The Intel Xeon Gold 6136 has fewer cores (12 vs 18) but a significantly higher base clock speed (3.0GHz vs 2.3GHz). This makes the 6136 better suited for applications that rely on single-thread performance or have per-core licensing costs, whereas the 6140 is better for general virtualization density.

Q: What are LRDIMMs and why are they used here?
A: LRDIMM stands for Load Reduced Dual Inline Memory Module. They are used in this 512GB RAM Server configuration to reduce the electrical load on the memory bus, allowing the system to support higher capacities and speeds with stable performance compared to standard RDIMMs.

Q: Can I use SATA drives with this RAID controller?
A: Yes, the RAID 730-8i controller supports both SAS and SATA drives. However, you cannot mix SAS and SATA drives within the same specific RAID array (virtual disk), though they can coexist in the same server chassis.

Q: Do I need a specific switch for the 32Gb Fibre Channel card?
A: To utilize the full 32Gb speed, you need a 32Gb FC switch (such as a Brocade G620). However, the card is backward compatible and will work with 16Gb or 8Gb FC switches at those respective speeds.
