  • Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating system vendors to better use the hardware for virtualization workloads.
  • Intel Advanced Vector Extensions 512 (AVX-512) enable acceleration of enterprise-class workloads, such as databases and enterprise resource planning.
  • Each processor has 6 memory channels with up 2 two DIMMs per channel running at up to 2666 MHz. 
  • Up to 3 TB of memory capacity using 128 GB 3DS RDIMMs (requires a processor with an "M" suffix)
  • Optional support for high-performance PCIe-attached NVMe Flash Storage solid-state drives (SSDs) can significantly improve I/O performance.
  • Embedded 4-port 10Gb Intel adapter built into the system board is based on the Intel Ethernet Connection X722 network controller.
  • With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon processor Scalable family. This integration helps to dramatically reduce I/O latency and increase overall system performance.
  • Support for high-bandwidth I/O adapters; up to two in each SN550 server.
  • Support for 40 Gb Ethernet, 16 Gb Fibre Channel, and FDR InfiniBand.
  • High-speed USB 3.0 port for connectivity to external devices.

Availability and serviceability

The SN550 provides the following features to simplify serviceability and increase system up-time:

  • 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), memory mirroring, and memory rank sparing for redundancy in the event of a non-correctable memory failure.
  • Tool-less cover removal provides easy access to upgrades and serviceable parts, such as CPU, memory, and adapter cards.
  • The Dual M.2 Boot Adapter supports RAID-1 which enables two installed M.2 drives to be configured as a redundant pair.
  • Hot-swap drives support integrated RAID-1 redundancy for data protection and greater system up-time.
  • Solid-state drives (SSDs), which offer significantly better reliability than mechanical HDDs for greater uptime. 
  • The power source independent light path diagnostics functionality provides individual LEDs that lead the technician to failed (or failing) components, which simplifies servicing, speeds up problem resolution, and helps improve system availability.
  • The built-in XClarity Controller continuously monitors system parameters, triggers alerts, and performs recovery actions in case of failures to minimize downtime.
  • Proactive Platform Alerts (including PFA and SMART alerts): Processors, voltage regulators, memory, internal storage (SAS/SATA HDDs and SSDs, NVMe SSDs, flash storage adapters), RAID controllers, and server ambient and sub-component temperatures. Alerts can be surfaced through the system XClarity Controller to managers such as Lenovo XClarity Administrator, VMware vCenter, and Microsoft System Center. These proactive alerts let you take appropriate actions in advance of possible failure, thereby increasing server uptime and application availability.
  • Built-in diagnostics in UEFI with Lenovo XClarity Provisioning Manager that supports the collection of service data to USB key drive or remote CIFS share folder for troubleshooting and reduced service time.
  • Auto-restart in the event of a momentary loss of AC power (based on power policy setting in the XClarity Controller service processor). 
  • Support for the XClarity Administrator Mobile app running on a supported smartphone and connected to the server through the service-enabled USB port, enables additional local systems management functions.
  • Three-year customer replaceable unit and on-site limited warranty; next business day 9x5. Optional service upgrades are available.

Manageability and security

The following powerful systems management features simplify the local and remote management of the SN550:

  • Support for Lenovo XClarity Administrator, providing auto-discovery, inventory tracking, monitoring, policy-based firmware updates, address pool management, configuration patterns and operating system installation.
  • The server includes an XClarity Controller (XCC) to monitor server availability and perform remote management. XCC Enterprise is supported as standard, which enables remote KVM, mounting of remote media files (ISO and IMG image files), boot capture, and power capping.
  • UEFI-based Lenovo XClarity Provisioning Manager, accessible from F1 during boot, provides system inventory information, graphical UEFI Setup, platform update function, RAID Setup wizard, operating system installation function, and diagnostic functions
  • Integrated Trusted Platform Module (TPM) 2.0 support enables advanced cryptographic functionality, such as digital signatures and remote attestation.
  • Supports Secure Boot to ensure only a digitally signed operating system can be used. Supported with HDDs and SSDs as well as M.2 SSD.
  • Support for Lenovo XClarity Energy Manager which captures real-time power and temperature data from the server and provides automated controls to lower energy costs.
  • Industry-standard Advanced Encryption Standard (AES) NI support for faster, stronger encryption.
  • Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system.
  • Intel Trusted Execution Technology provides enhanced security through hardware-based resistance to malicious software attacks, which allows an application to run in its own isolated space that is protected from all other software that is running on a system.

Energy efficiency

The SN550 offers the following energy-efficiency features to save energy, reduce operational costs, increase energy availability, and contribute to a green environment:

  • The component-sharing design of the Flex System chassis provides ultimate power and cooling savings.
  • The Intel Xeon Processor Scalable Family of processors offer significantly better performance than previous generations of processors, while fitting into the same TDP limits.
  • Intel Intelligent Power Capability powers individual processor elements on and off as needed, which reduces power draw.
  • Solid state drives (SSDs) use as much as 80% less power than traditional spinning 2.5-inch HDDs.
  • The SN550 uses hexagonal ventilation holes, which can be grouped more densely than round holes providing more efficient airflow through the system.

Chassis support

The SN550 server is supported in the Flex System chassis as listed in the following table.

Table 14. Chassis support

Chassis models Description Supports SN550 
8721-HC1 based:
8721-A1x, LRx, DCx
8721-K1G, E1Y, E2Y

Note: CMM2 firmware should be 1.6.1 or later to support ThinkSystem compute nodes

Up to 14 SN550 servers can be installed in the chassis; however, the actual number that can be installed in a chassis depends on the following factors:

  • TDP power rating for the processors that are installed in the SN550
  • Number of power supplies that are installed in the chassis
  • Capacity of the installed power supplies (2100 W or 2500 W)
  • Chassis power redundancy policy that is used (N+1 or N+N)

The following table provides guidelines about what number of SN550 servers can be installed. For more information, use Lenovo Capacity Planner, which is found at the following web page:
https://datacentersupport.lenovo.com/us/en/products/solutions-and-software/software/lenovo-capacity-planner/solutions/ht504651

The following color coding was used In the table:

  • Green = No restriction on the number of SN550 servers that can be installed
  • Yellow = Some bays must be left empty in the chassis

Memory options

The SN550 uses Lenovo TruDDR4 memory operating at speeds up to 2666 MHz. All DIMMs can operate at a speed of 2666 MHz, both at 1 DIMM per channel and 2 DIMMs per channel. However, if the processor selected has a lower memory bus speed (eg 2400 MHz), then all DIMMs will operate at that lower speed.

TruDDR4 Memory uses the highest quality components that are sourced from Tier 1 DRAM suppliers and only memory that meets the strict requirements of Lenovo is selected. It is compatibility tested and tuned on every ThinkSystem server to maximize performance and reliability. TruDDR4 Memory has a unique signature that is programmed into the DIMM that enables ThinkSystem servers to verify whether the memory that is installed is qualified and supported by Lenovo.

From a service and support standpoint, Lenovo TruDDR4 memory automatically assumes the Lenovo system warranty and Lenovo provides service and support worldwide.

The following table lists the memory options that are available for the SN550 server.

The following rules apply when selecting the memory configuration:

  • The server supports RDIMMs, LRDIMMs and 3DS RDIMMs. UDIMMs are not supported.
  • Mixing RDIMMs and LRDIMMs is not supported.
  • Mixing 3DS RDIMMs with either RDIMMs or LRDIMMs is not supported
  • Mixing x4 and x8 DIMMs is supported.
  • For best performance, populate memory DIMMs in quantities of 6 or 12 per processor, so that all memory channels are used.
  • A configuration of more than 768 GB of memory per processor requires processor(s) with an "M" suffix

For best performance, consider the following:

  • Populate memory DIMMs in quantities of 6 or 12 per processor, so that all memory channels are used.
  • When mixing 16 GB and 32 GB DIMMs in the same configuration, use 16GB 2Rx8 DIMMs instead of 16 GB 1Rx4 DIMMs for better performance.
  • Populate memory channels so they all have the same total memory capacity
  • Ensure all memory controllers on a processor socket have the same DIMM configuration.
  • All processor sockets on the same physical server should have the same DIMM configuration.

The following memory protection technologies are supported:

  • ECC
  • SDDC (for x4-based memory DIMMs; look for "x4" in the DIMM description)
  • ADDDC (for x4-based memory DIMMs; Gold and Platinum processors only)
  • Memory channel mirroring
  • Memory rank sparing

If memory channel mirroring is used, then DIMMs must be installed in pairs or sets of three (minimum of one pair or set of three per processor), and all DIMMs in the pair or set of three must be identical in type and size. 50% of the installed capacity is available to the operating system.

If memory rank sparing is used, then a minimum of one quad-rank DIMM or two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need to be identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The largest rank in the channel will be automatically selected as the spare rank. The amount of memory available to the operating system depends on the number, capacity and rank counts of the DIMMs installed.

Internal storage

The SN550 server has two 2.5-inch hot-swap drive bays that are accessible from the front of the blade server (see Figure 2). Depending on server configuration and installed backplane, these bays connect to either the included 6 Gbps SATA controller, optional Lenovo RAID controllers or directly to PCIe lanes for NVMe drives.

In addition, the SN550 can also support one or two M.2 form factor SSD drives on a separate adapter. The following table lists the supported M.2 adapters (enablement kits). For more information, see the ThinkSystem M.2 Drives and M.2 Adapters product guide: https://lenovopress.com/lp0769

Virtualization support: The integrated SATA controller can be used with virtualization hypervisors, including VMware ESXi, Linux KVM, Xen, and Microsoft Hyper-V. However, support is limited to AHCI (non-RAID) mode. RSTe mode is not supported with virtualization hypervisors.

SED encryption key management with ISKLM

The server supports FIPS 140-2 self-encrypting drives (SEDs) as listed in the Internal drive options section. To effectively manage a large deployment of these drives in Lenovo servers, IBM Security Key Lifecycle Manager (SKLM) offers a centralized key management solution. A Lenovo Feature on Demand (FoD) upgrade is used to enable this SKLM support in the management processor of the server.

The following table lists the part numbers and feature codes for the upgrades.

Internal tape drives

The server does not support an internal tape drive. However, it can be attached to external tape drives by using Fibre Channel connectivity.

Optical drives

The server does not support an internal optical drive option, however, you can connect an external USB optical drive. See https://datacentersupport.lenovo.com/us/en/solutions/pd011281 for information about available external optical drives from Lenovo. Alternatively, use the remote media feature of the XClarity Controller and the Chassis Management Module.

Embedded 10Gb Network Adapter

The SN550 includes an embedded 4-port 10Gb Intel controller built into the system board. As listed in the Models section, some SN550 models include the Fabric Connector needed to connect the embedded controller to the midplane of the Flex System chassis. For models that do not include the Fabric Connector, it can be ordered and installed in the field. Ordering information is listed in the following table.

Table 29. Fabric Connector ordering information
Part number Feature code Description
7M27A03927 AUYN Lenovo ThinkSystem Server Fabric Connector

The location of the fabric connector is shown below.

SN550 fabric connector
Figure 6. Location of fabric connector in SN550 server

Tip: To provide connectivity for all 4 adapter ports, make sure the associated chassis I/O module has adequate internal switch ports.

The Adapter to I/O bay correspondence table shows how the 4 ports of the embedded controller connect through the Fabric Connector to the corresponding switch ports. The Fabric Connector can be removed, if required, to allow the installation of an I/O adapter on I/O connector 1.

The embedded 10Gb controller is based on the Intel Ethernet Connection X722 network controller which is part of the Intel C624 "Lewisburg" PCH chipset of the SN550 and other Lenovo ThinkSystem servers.

The Intel X722 controller is optimized for data center, cloud, and mobile applications and includes the following features:

  • VXLAN/NVGRE Hardware Offloads: These stateless offloads preserve application performance for overlay networks. With these offloads, it is possible to distribute network traffic across CPU cores. At the same time, the controller offloads LSO, GSO, and checksum from the host software, which reduces CPU overhead.
  • Low latency: Intel Ethernet Flow Director delivers hardware-based application steering and Intel Data Direct I/O makes the processor cache the primary destination and source of I/O data rather than main memory.
  • Virtualization performance: With Intel Virtualization Technology (VT), the controller delivers outstanding I/O performance in virtualized server environments. The controller reduces I/O bottlenecks by providing intelligent offloads for networking traffic per virtual machine (VM), which enables near-line rate speeds for small packets and supports almost an unlimited amount of isolated traffic flows so that you can scale your cloud environment.
  • Next-generation VMDq: The controller supports up to 128 VMDq VMs and offers enhanced Quality of Service (QoS) by providing weighted round-robin servicing for the Tx data. The controller offloads the data-sorting functionality from the hypervisor to the network silicon, which improves data throughput and CPU usage.
  • SR-IOV implementation: Provides an implementation of the PCI-SIG standard for I/O Virtualization. The physical configuration of each port is divided into multiple virtual ports. Each virtual port is assigned to an individual VM directly by bypassing the virtual switch in the Hypervisor, which results in near-native performance.
  • iWarp RDMA support implements kernel bypass and direct data placement and allows for more efficient high-speed networking by eliminating queues and network related interrupts
  • VM load balancing: Provides traffic load balancing (Tx and Rx) across VMs that are bound to the team interface. It also provides fault tolerance if a switch, port, or cable fails or is disconnected.
  • Auto-detect (PnP) feature for the LOM adapters, enabling you to change speed (eg from a 1Gb LOM to 10 Gb LOM) and the network interface will automatically reconfigure during the boot process.

Note: The onboard Ethernet controller does not support 10 Mb or 100 Mb Ethernet connections.

I/O expansion options

The SN550 has two I/O expansion connectors for attaching I/O adapter cards. The I/O expansion connectors use a high-density, 216-pin PCIe connection. Installing I/O adapter cards allows the server to connect with switch modules in the chassis. Each slot has a PCI Express 3.0 x16 host interface and both slots support the same form-factor adapters.  If the SN550 has a Fabric Connector in adapter slot 1, it must be removed first to use that slot for an optional I/O adapter.

The following figure shows the location of the I/O expansion connectors.


Figure 7. Location of the I/O adapter slots in the ThinkSystem SN550 server

A compatible switch or pass-through module must be installed in the corresponding I/O bays in the chassis, as indicated in the following table. Installing two switches means that all ports of the adapter are enabled, which improves performance and network availability.

Light Path Diagnostics

The SN550 includes light path diagnostics. If an environmental condition exceeds a threshold or if a system component fails, XCC lights LEDs inside the server to help you diagnose the problem and find the failing part.

For quick problem determination when you are physically at the server, the server offers the following three-step guided path:

  • Illuminate the fault LED on the front panel. 
  • Identify the fault in the light path diagnostics panel, as shown in the following figure.
  • If a DIMM is faulty, the LED next to it is illuminated.

The SN550 light path diagnostics panel is inside the server near the front panel, as shown in the following figure.


Figure 10. Location of SN550 light path diagnostics panel

To illuminate the light path diagnostics LEDs, power off the server, slide it out of the chassis, and press and hold the power button. The power button doubles as the light path diagnostics reminder button when the server is removed from the chassis.

The meanings of the LEDs in the light path diagnostics panel are listed in the following table.

Warranty options

The ThinkSystem SN550 (machine type 7X16) has a 3-year warranty.

The standard warranty terms are customer-replaceable unit (CRU) and onsite (for field-replaceable units FRUs, only) with standard call center support during normal business hours and 9x5 Next Business Day Parts Delivered.

Some countries might have different warranty terms and conditions than the standard warranty. This is due to local business practices or laws in the specific country. Local service teams can assist in explaining country-specific terms when needed. Examples of country-specific warranty terms are second or longer business day parts delivery or parts-only base warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will dispatch a service technician to the customer site to perform the replacement. Onsite labor under base warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units (FRUs). Parts that are determined to be customer-replaceable units (CRUs) do not include onsite labor under base warranty.

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spares parts.

Also available are Lenovo Services warranty maintenance upgrades and post-warranty maintenance agreements, with a well-defined scope of services, including service hours, response time, term of service, and service agreement terms and conditions.

Lenovo warranty service upgrade offerings are country-specific. Not all warranty service upgrades are available in every country. For information about Lenovo warranty service upgrade offerings that are available in your country or area, refer to the following resources:

In general, the following Lenovo warranty service upgrades are available:

  • Basic Hardware Installation Services

    Lenovo experts can seamlessly manage the physical installation of your server, storage, or networking hardware. Working at a time convenient for you (business hours or off shift), the technician will unpack and inspect the systems on your site, install options, mount in a rack cabinet, connect to power and network, check and update firmware to the latest levels, verify operation, and dispose of the packaging, allowing your team to focus on other priorities.
