https://lenovopress. com/lp1161-thinksystem-sr655-server#syst ems-management Introduction The Lenovo ThinkSystem SR655 is a 1-socket 2U server that features the new AMD EPYC 7002 Rome family of processors. With up to 64 cores per processor and support for the new PCIe 4.0 standard for I/O, the SR655 offers the ultimate in single-socket server performance. With up to 128 PCIe lanes, the server is ideal for workloads that can take advantage of GPU processing and high-performance NVMe drives. Suggested uses: AI Inference, VDI, OLTP, Analytics, software-defined storage Figure 1. Lenovo ThinkSystem SR655 Did you know? By using a high-performance server with only one processor installed, you can take advantage of lower software costs when the software licensing is using a per-socket model. The SR655 has been designed to take advantage of the features of the EPYC 7002 Rome processors, such as the full performance of 225W 64-core processors, support for 3200 MHz memory and PCIe Gen 4.0 support. Competitive servers that are based on the older EPYC 7001 Naples designs may not be able to offer these performance features. Key features Combining performance and flexibility, the SR655 server is a great choice for enterprises of all sizes. The server offers a broad selection of drive and slot configurations and offers high performance features that industries such as finance, healthcare and telco need. Outstanding reliability, availability, and serviceability (RAS) and high-efficiency design can improve your business environment and can help save operational costs. Scalability and performance The SR655 offers numerous features to boost performance, improve scalability and reduce costs: Supports the new AMD EPYC 7002 family of processors Supports processors with up to 64 cores and 128 threads, core speeds of up to 3.2 GHz, and TDP ratings of up to 225W. Support for up to 16 TruDDR4 memory DIMMs, with 8 memory channels and 2 DIMMs per channel. With 1 DIMM installed per channel (8 DIMMs total), memory operates at up to 3200 MHz. With 2 DIMMs per channel (16 DIMMs total), memory operating at up to 2933 MHz. Using 64GB DIMMs, the server supports up to 1TB of system memory. Supports 3 double-width GPUs up to 300W each, or 6 single-width GPUs up to 75W each. A 6:1 ratio of GPUs to CPUs means substantial processing power is available with just one CPU. Supports up to 32x 2.5-inch hot-swap drive bays, by using combinations of front-accessible (up to 24 bays), mid-accessible (up to 8), and rear-accessible (up to 4) drive bays. Supports 3.5-inch drive bays for lower-cost high-capacity storage. 2.5-inch and 3.5-inch drive bays can be mixed in several combinations. Supports 16x SATA drives using the onboard SATA controller (no additional adapter needed), enabling lower cost, high capacity storage solution for cold storage workloads. Supports up to 16x NVMe drives without oversubscription of PCIe lanes (1:1 connectivity), or up to 32x NVMe drives with a 2:1 oversubscription. Planned support of up to 28x NVMe drives without oversubscription. The use of NVMe drives maximizes drive I/O performance, in terms of throughput, bandwidth, and latency. Supports high-speed RAID controllers from Broadcom providing 12 Gb SAS connectivity to the drive backplanes. A variety of RAID adapters are available, with cache and support for up to 24 drives on a single controller. Supports M. 2 drives for convenient operating system boot functions or data storage. Available M. 2 adapters support either one M. 2 drive or two M. 2 drives in a RAID 1 configuration for performance and reliability. The server has a dedicated industry-standard OCP 3.0 small form factor (SFF) slot, with a PCIe 4.0 x16 interface, supporting a variety of Ethernet network adapters. Simple-swap mechanism with thumbscrews and pull-tab enables tool-less installation and removal of the adapter. Supports shared BMC network sideband connectivity to enable out-of-band systems management. The server offers PCI Express 4.0 I/O expansion capabilities that doubles the theoretical maximum bandwidth of PCIe 3.0 (16GT/s in each direction for PCIe 4.0, compared to 8 GT/s with PCIe 3.0). A PCIe 4.0 x16 slot provides 64 GB/s bandwidth, enough to support a 400GbE network connection. A total of up to 9 PCIe 4.0 slots (8 with rear access, 1 internal for a RAID adapter) plus a slot dedicated to the OCP adapter. Availability and serviceability The SR655 provides many features to simplify serviceability and increase system uptime: The server uses ECC memory and supports memory RAS features including Single Device Data Correction (SDDC, also known as Chipkill), Patrol/Demand Scrubbing, DRAM Address Command Parity with Replay, and DRAM Uncorrected ECC Error Retry. The server offers hot-swap drives, supporting RAID redundancy for data protection and greater system uptime. The M. 2 SATA RAID Boot Adapter supports RAID-1 which enables two installed M. 2 drives to be configured as a redundant pair. The server has up to two hot-swap redundant power supplies and six hot-swap redundant fans to provide availability for business-critical applications. The power-source-independent light path diagnostics uses LEDs to lead the technician to failed (or failing) components, which simplifies servicing, speeds up problem resolution, and helps improve system availability. Solid-state drives (SSDs) offer more reliability than traditional mechanical HDDs for greater uptime. The built-in ASPEED AST2500 baseboard management controller (BMC) continuously monitors system parameters, triggers alerts, and performs recovery actions in case of failures to minimize downtime. Proactive Platform Alerts: Voltage regulators, memory, fans, power supplies, server ambient and subcomponent temperatures. Alerts can be surfaced through the BMC to managers such as Lenovo XClarity Administrator. These proactive alerts let you take appropriate actions in advance of possible failure, thereby increasing server uptime and application availability. Web-based ThinkSystem System Manager (TSM) provides remote access to the BMC for remote management. Lenovo XClarity Provisioning Manager Lite (LXPM Lite) tool can be used to install an operating system on the server and perform system diagnostics. Three-year or one-year customer-replaceable unit and onsite limited warranty, 9 x 5 next business day. Optional service upgrades are available. Manageability and security Systems management features simplify local and remote management of the SR655: Supports Lenovo XClarity Provisioning Manager Lite (LXPM Lite) for system setup and firmware upgrades. An integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup, configuration, and updates, and simplifies error handling. Support for industry standard management protocols, IPMI 2.0, SNMP 3.0, Redfish REST API, serial console via IPMI An integrated hardware Trusted Platform Module (TPM) supporting TPM 2.0 enables advanced cryptographic functionality, such as digital signatures and remote attestation. Administrator and power-on passwords help protect from unauthorized access to the server. Support for Lenovo XClarity Energy Manager, which captures real-time power and temperature data from the server and integrates with Redfish-based applications to provide automated controls to lower energy costs. Supports AMD Secure Root-of-Trust, Secure Run and Secure Move features to minimize potential attacks and protect data as the OS is booted, as applications are run and as applications are migrated from server to server. Supports Secure Boot to ensure only a digitally signed operating system can be used. Industry-standard Advanced Encryption Standard (AES) NI support for faster, stronger encryption. Energy efficiency The SR655 offers the following energy-efficiency features to save energy, reduce operational costs, and increase energy availability: Energy-efficient planar components help lower operational costs. High-efficiency power supplies with 80 PLUS Platinum and Titanium certifications Low-voltage 1.2 V DDR4 memory offers energy savings compared to 1.35 V and 1.5 V DDR3 DIMMs. Solid-state drives (SSDs) consume as much as 80% less power than traditional spinning 2.5-inch HDDs. The server uses hexagonal ventilation holes, which can be grouped more densely than round holes, providing more efficient airflow through the system and thus keeping your system cooler. Optional Lenovo XClarity Energy Manager provides power and thermal monitoring to help achieve lower heat output and reduced cooling needs.
