Bottom Line

The SR630 from Lenovo offers plenty of memory and storage capacity, along with versatile configurations. It also comes with enterprise-class RAS features. With world record benchmark scores for 1-processor rack server performance for compute-intensive applications (on two key benchmarks), it offers plenty of bang for the buck.

That makes this rack server ideal for single-threaded compute-intensive applications, such as High Frequency Trading (HFT), and other financial industry workloads. All that comes at a premium price, making it more suitable for large enterprise users, as well as SMEs with demanding applications.

This Lenovo is at a similar price range to the IBM Power S922 included in this guide. The IBM model wins on memory while the Lenovo machine provides far more storage.

Product Description:

The Lenovo ThinkSystem SR630 is a 2-socket 1U rack server suitable for a wide range of workloads for small businesses and large enterprises. It offers reliability, management, security, performance, and the flexibility for future growth. The SR630 server is designed to handle databases, virtualization, cloud computing, infrastructure security, systems management, collaboration/email, streaming media, web serving, High Performance Computing (HPC), and other workloads.

Featuring the Intel Xeon Processor Scalable Family, it delivers scalable performance and storage capacity. It supports up to two processors, up to 3 TB of 2666 MHz TruDDR4 memory, up to 12x 2.5-inch or 4x 3.5-inch drive bays with an extensive choice of NVMe PCIe SSDs, SAS/SATA SSDs, and SAS/SATA HDDs. The company also provides flexible I/O expansion options with the LOM slot, the dedicated storage controller slot, and up to 3x PCIe slots.

The SR630 server features an AnyBay design that allows a choice of drive interface types in the same drive bay: SAS drives, SATA drives, or U.2 NVMe PCIe drives. Onboard NVMe PCIe ports allow direct connections to the U.2 NVMe PCIe SSDs, which frees up I/O slots and helps lower NVMe solution acquisition costs. It is designed to meet ASHRAE A4 standards in select configurations, which enable users to lower energy costs, while still maintaining reliability.
