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:

Memory capacity of processors

Second-generation Xeon Scalable processors are limited to the amount of memory they can address, as follows:

  • Processors with an L suffix (eg 8280L): Up to 4.5 TB per processor
  • Processors with an M suffix (eg 8280M): Up to 2 TB per processor
  • All other processors: Up to 1 TB per processor

The calculation of the total memory per processor includes both the system memory DIMMs and the Persistent Memory DCPMMs installed in the server.

For example:

  • A configuration using 12x 64GB DIMMs per processor is a total of 768 GB, which means that neither an M nor an L processor is required
  • A configuration using 6x 32GB DIMMs + 6x 256GB DCPMMs is a total of 1.69 TB which means an M processor is required (an L processor may also be used)
  • A configuration using 6x 64GB DIMMs + 6x 512GB DCPMMs is a total of 3.375 TB which means an L processor is required

Memory options

The SN550 with second-generation Intel Xeon Scalable processors uses Lenovo TruDDR4 memory operating at up to 2933 MHz. The server supports 12 DIMMs per processor, which corresponds to 24 DIMMs with two processors installed. Each processor has six memory channels with two DIMMs per channel.

The SN550 with second-generation Intel Xeon Scalable processors also supports Intel Optane DC Persistent Memory, as described in the Persistent Memory section.

With second-generation processors, the server supports these memory DIMMs:

  • 2666 MHz DIMMs, that operate at 2666 MHz both at 1 DIMM per channel and 2 DIMMs per channel
  • 2933 MHz DIMMs, that operate at 2933 MHz at 1 DIMM per channel, and at 2666 MHz at 2 DIMMs per channel

Note that if the processor selected has a lower memory bus speed (eg 2133 MHz or 2400 MHz), then all DIMMs will operate at lower sppeed, even if the DIMMs are rated for 2666 MHz or 2933 MHz. See the Processor features section for details.

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

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

2666 MHz DIMMs
7X77A01302 AUNB ThinkSystem 16GB TruDDR4 2666 MHz (1Rx4 1.2V) RDIMM 24 (12 per processor)

The following rules apply when selecting the memory configuration:

  • The server supports RDIMMs, LRDIMMs and 3DS RDIMMs. UDIMMs are not supported.
  • Mixing RDIMMs, LRDIMMs or 3DS RDIMMs is not supported.
  • Mixing x4 and x8 DIMMs is supported.
  • Mixing of 2666 MHz and 2933 MHz is supported, however, all installed memory will operate at the lowest speed.

For best performance, consider the following:

  • Ensure the memory installed is at least the same speed as the memory bus of the selected processor.
  • 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)
  • Memory 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 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.

Persistent Memory

The SN550 server supports Intel Optane DC Persistent Memory, a new class of memory and storage technology explicitly architected for data center usage. Persistent Memory offers significantly lower latency than fetching data from SSDs, even NVMe SSDs, and offers higher capacities than system memory.

Using Lenovo ThinkSystem servers running applications that are tuned for Intel Optane DC Persistent Memory will result in lower data latency compared to solid-state drive technology. When data is stored closer to the processor on nonvolatile media, applications can see significant overall improvement in performance. 

The following table lists the ordering information for the DC Persistent Memory modules (DCPMMs).

Description Maximum
supported
4ZC7A15110 B4LV ThinkSystem 128GB TruDDR4 2666MHz (1.2V) Intel Optane DC Persistent Memory 12 (6 per processor)
4ZC7A15111 B4LW ThinkSystem 256GB TruDDR4 2666MHz (1.2V) Intel Optane DC Persistent Memory 12 (6 per processor)
4ZC7A15112 B4LX ThinkSystem 512GB TruDDR4 2666MHz (1.2V) Intel Optane DC Persistent Memory 12 (6 per processor)

The following are the requirements when installing DCPMMs:

  • Only second-generation Intel Xeon Scalable Family processors support DCPMMs. First generation Xeon Scalable processors are not supported.
  • Only the Platinum level, Gold level, and the Silver 4215 processor models support DCPMMs. All other Silver and all Bronze level processors do not support DCPMMs. See the Processor features section for details.
  • Only Memory Mode is supported for all SN550 configurations. App Direct Mode and Mixed Mode are only supported under Special Bid conditions.
  • All installed DCPMMs must be the same size. Mixing DCPMMs of different capacities is not supported
  • Maximum 6 DCPMMs per processor (install 1 in each memory channel)
  • Minimum 2 TruDDR4 DIMMs per processor (1 per memory controller)
  • For Memory Mode, minimum 2 DCPMMs per processor (install 1 per memory controller)
  • With Memory Mode, the ratio of memory to DCPMMs must be between 1:16 and 1:4, but the recommended ratio is 1:4 for the best performance. For example, 6x 16GB DIMMs + 2x 256GB DCPMMs is a ratio of 1:5.33.
  • For each memory channel with both a DCPMM and a TruDDR4 DIMM installed, the DCPMM is installed in channel slot 1 (closest) and the DIMM is installed in channel slot 0
  • To maximize performance, balance all memory channels
  • Memory mirroring is not supported in DCPMM Memory Mode.
  • Memory sparing is not supported with DCPMMs installed

App Direct Mode and Mixed Mode are only supported under Special Bid conditions. Under Special Bid conditions, the following are the requirements:

  • For App Direct Mode, mimimum 1 DCPMM installed in the server (any processor)
  • When Mixed Mode is used, the ratio of memory to DCPMMs must be between 1:16 and 1:4, but the recommended ratio is 1:4 for the best performance. For example, 6x 16GB DIMMs + 2x 256GB DCPMMs is a ratio of 1:5.33. This ratio requirement does not apply to App Direct mode.
  • In configurations with DCPMMs installed, memory mirroring is supported, with two restrictions:
    • Mirroring is only enabled on the DRAM DIMMs installed in the server; The DCPMMs themselves do not support mirroring.
    • Only App Direct mode is supported. Memory mirroring cannot be enabled when DCPMMs are in Memory Mode or Mixed Mode.

DCPMMs offer the following memory protection technologies:

  • ECC
  • SDDC
  • DDDC
  • Patrol scrubbing
  • Demand scrubbing

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.

Supported drives are listed in the Internal drive options section. 

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.

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.
