  • 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 1.5 TB of memory capacity using 64 GB LRDIMMs (support coming later for 128GB DIMMs and up to 3TB capacity with certain processors).
  • 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.
  • New 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.

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 and LRDIMMs. UDIMMs are not supported.
  • Mixing RDIMMs and 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.

The following memory protection technologies are supported:

  • ECC
  • SDDC (for x4-based memory DIMMs; look for "x4" in the DIMM description)
  • 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.  Storage backplanes, RAID and M.2 upgrades are listed below.  

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.

M.2 drives

The server supports an adapter that provides two M.2 form-factor SATA drives for use as an operating system boot solution. The drives are configured by default as a RAID-1 mirrored pair for redundancy.

The M.2 drives install into an M.2 adapter which in turn is installed in a dedicated slot on the system board. See the internal view of the server in the Components and connectors section for the location of the M.2 slot.

The M.2 adapter supported is the Dual M.2 Boot Adapter, which supports one or two M.2 drives; available as ThinkSystem M.2 with Mirroring Enablement Kit, 7Y37A01093 (note that the SIngle M.2 adapter is not supported, but a single M.2 drive in the Dual M.2 Adapter is supported).

The Dual M.2 Boot Adapter with one 128GB M.2 drive partially inserted is shown in the following figure. The second M.2 drive is installed on the other side of the adapter.

http://www3.lenovo.com/us/en/data-center/solutions/alliances/vmware/#tab-VMware-tab-main-2 

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 adapter built into the system board. Each SN550 model that uses the embedded Intel adapter also has the Fabric Connector installed in I/O connector 1 to provide connectivity to the Flex system chassis midplane. The feature code for the Fabric Connector is AUYN. Figure 3 shows the location of the Fabric Connector.

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 adapter 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.

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 6. 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.

Power supplies

Power to the blade server is derived from the power supplies that are installed in the chassis. There are no server options regarding power supplies.

System Management

The server contains an integrated service processor, XClarity Controller (XCC), which provides advanced service-processor control, monitoring, and alerting functions. The XCC is based on the Pilot4 XE401 baseboard management controller (BMC) using a dual-core ARM Cortex A9 service processor.

Local management

As shown in Figure 2, the SN550 front panel includes a USB port, status indicators, a button to enable management via the USB port and a console breakout cable port. The breakout cable supplied with the chassis provides serial, video and a USB port for connecting a local console. The USB ports on the breakout cable support keyboard and mouse; storage devices are not supported.

System status with XClarity Mobile

The Lenovo XClarity Mobile (LXCM) app now includes a tethering function where you can connect your Android or iOS device to the server via USB to see the status of the server.

The steps to connect the mobile device are as follows:

  1. Enable USB Management on the server, by pressing and holding for 3 seconds the dedicated USB management button on the front of the server.
  2. Connect the mobile device via a USB cable to the server's USB port with the management symbol 
  3. In iOS or Android settings, enable Personal Hotspot or USB Tethering
  4. Launch the Lenovo XClarity Mobile app

Once connected you can see the following information:

  • Server status including error logs (read only, no login required)
  • Server management functions (XClarity login credentials required)

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 9. 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.

Table 29. Light path diagnostic panel LEDs

LED Meaning
LIGHT PATH The light path diagnostics panel is operational.
SYSTEM  BOARD A system board error is detected.
NMI A non-maskable interrupt (NMI) occurred.
CPU MISMATCH The processors are mismatched.
TEMP An over-temperature condition occurred that was critical enough to shut down the server.
MEMORY A memory fault occurred. The corresponding DIMM error LEDs on the system board are also lit.
STORAGE BP 1 A hard disk drive backplane error has occurred.
M.2  A M.2 error has occurred.

The front of the server also houses an information pull-out tab. See Figure 2 for the location. A label on the tab shows the network information (MAC address and other data) to remotely access XClarity Controller.

Remote management

Lenovo XClarity Controller (XCC) is an all-new embedded management engine common in every ThinkSystem server. 

There are two ways to access the management processor:

  • Command-line interface. To access the CLI interface, use SSH to log in to the management processor.

  • Web-based interface. To access the web-based interface, point your browser to the IP address for the management processor. The new intuitive interface includes at-a-glance visualizations and simple access to common system actions.  The dashboard is shown in the following figure.

Lenovo XClarity Administrator is a centralized resource management solution designed to reduce complexity, speed response, and enhance the availability of Lenovo systems and solutions.

Lenovo XClarity Administrator provides agent-free hardware management for ThinkSystem servers, in addition to ThinkServer, System x, and Flex System servers. The administration dashboard is based on HTML 5 and allows fast location of resources so tasks can be run quickly.

Because Lenovo XClarity Administrator does not require any agent software to be installed on the managed endpoints, there are no CPU cycles spent on agent execution, and no memory is used, which means that up to 1GB of RAM and 1 - 2% CPU usage is saved, compared to a typical managed system where an agent is required.

Lenovo XClarity Administrator provides full management function to ThinkSystem servers, including the following:

  • Discovery
  • Inventory
  • Monitoring and alerting
  • Call home
  • Centralized user management
  • Cryptography modes, server certificates, and encapsulation
  • Configuration patterns
  • Operating system deployment
  • Firmware updates
