ThinkSystem SD550 V3

The Lenovo ThinkSystem SD550 V3 is a two-socket server in a 2U2N multi-node form factor. Combining the efficiency and density of blades with the value and simplicity of rack-based servers, the SD550 V3 delivers a cost-efficient scale-out platform that is thermally designed to deliver maximum performance in the smallest footprint. The solution consists of a 2U ThinkSystem D3 Chassis containing two front-access SD550 V3 servers (nodes). Each node incorporates two 5th Gen Intel Xeon Scalable processors.

The SD550 V3 is well suited for workloads including cloud computing, hyperconverged infrastructure, and energy-efficient transactional processing.

The Lenovo ThinkSystem SD550 V3 server supports one or two 5th Gen Intel Xeon Scalable processors, plus support for the latest low-profile GPUs, and fast networking and storage. Two SD550 V3 servers can be installed in the D3 Chassis, and each server has its own fans to ensure proper cooling for installed components, and its own networking to ensure maximum performance.

The front-accessible design optimized for best-in-class thermal capabilities provides a dense, flexible solution with a low TCO. The half-wide, dual-socket server is designed for data centers that require high performance but are constrained by floor space.

The ThinkSystem D3 Chassis is an efficient, 2U rack mount enclosure with no built-in networking or switching capabilities; therefore, it requires no enclosure-level management. Sensibly designed to provide shared, high-efficiency power for housed servers, the D3 Chassis is designed to scale with your business needs.

Scalability and performance

The SD550 V3 server offers numerous features to boost performance, improve scalability, and reduce costs:

• Each SD550 V3 server supports up to two 5th Gen Intel Xeon Scalable processors, 16 TruDDR5 DIMMs, two PCIe x16 slots plus an OCP 3.0 slot for high-speed I/O, and up to six 2.5-inch drive bays, all in a half-wide 2U form factor.
• Up to two SD550 V3 servers are installed in the D3 Chassis, occupying only 2U of rack space. It is a dense and scalable offering.
• Supports one or two 5th Gen Intel Xeon Processor Scalable processors
• TDP ratings of up to 350W
• Up to 64 cores
• Core speeds of up to 3.9 GHz
• Support for DDR5 memory DIMMs to maximize the performance of the memory subsystem. Each node supports the following:
• Up to 16 DDR5 memory DIMMs, 8 DIMMs per processor
• 8 memory channels per processor (1 DIMM per channel)
• Supports 1 DIMM per channel operating at 5600 MHz
• Using 128GB 3DS RDIMMs, the server supports up to 2TB of system memory
• Each SD550 V3 server supports up to six 2.5-inch hot-swap drives supporting SATA or NVMe SSDs using onboard controllers. For configurations with two processors, the server also supports a RAID adapter with SAS or SATA drive support. NVMe drives can have a PCIe 5.0 x4 interface which maximizes I/O performance in terms of throughput, bandwidth, and latency.
• Supports two M.2 SATA or NVMe drives for convenient operating system boot or OS-based storage functions. Optional RAID-1 redundancy using Intel VROC RAID.
• The server has a dedicated industry-standard OCP 3.0 slot, with a PCIe 5.0 x16 interface, supporting a variety of Ethernet network adapters. A simple-swap mechanism with a thumbscrew and pull-tab enables tool-less installation and removal of the adapter. The adapter supports shared BMC network sideband connectivity (NC-SI) to enable out-of-band systems management.
• Up to two PCIe x16 full-height half-length (FHHL) slots (1x PCIe 5.0, 1x PCIe 4.0) with two processors installed. With one processor, the server supports up to one PCIe 5.0 x16 slot.
• The server offers PCI Express 5.0 I/O expansion capabilities that doubles the theoretical maximum bandwidth of PCIe 4.0 (32GT/s in each direction for PCIe Gen 5, compared to 16 GT/s with PCIe Gen 4 and 8 GT/s with PCIe Gen 3). A PCIe 5.0 x16 slot provides 128 GB/s bandwidth, enough to support a dual-port 200GbE network connection.

Availability and serviceability

The SD550 V3 server and the D3 Chassis provide many features to simplify serviceability and increase system uptime:

• Designed to run 24 hours a day, 7 days a week
• The server offers Single Device Data Correction (SDDC, also known as Chipkill), Adaptive Double-Device Data Correction (ADDDC, also known as Redundant Bit Steering or RBS), and memory mirroring for redundancy in the event of a non-correctable memory failure.
• The server offers hot-swap drives, supporting RAID-1 redundancy (using Intel VROC) for data protection and greater system uptime.
• The server supports two M.2 drives with support for RAID-1 (using Intel VROC)
