One-processor configurations

The SN550 V2 can be used with only one processor installed. Core functions of the server (including the XClarity Controller) are connected to processor 1 as shown in the System architecture section.

With only one processor, the server has the following capabilities:

  • 8 memory DIMMs for a 1TB maximum
  • I/O expansion slot 1 is available
  • 2x 2.5-inch drive support, SAS/SATA or NVMe/SATA

The following functions are not supported with only 1 processor installed:

  • I/O expansion slot 2
  • Use of EDSFF drives

Thermal restrictions by processor

Processors with a high TDP value or high thermal profile require a lower ambient temperature. See the Supported environment section for details.

Processor restriction by power supply

For existing Flex System customers where the SN550 V2 will be installed in an existing Flex System Enterprise Chassis, if you configure the SN550 V2 to have processors with a TDP of 135W or larger, then check which power supplies are installed in the chassis. If the chassis has Delta power supplies, then the processors will be capped at 125W due to an issue with the Delta power supplies. To prevent this from happening, replace the power supplies with Artesyn power supplies.

For new Flex System customers, if your order includes a new Enterprise Chassis, then the correct power supplies will already be configured so no further action is needed.

Memory options

The SN550 V2 uses Lenovo TruDDR4 memory and supports 8 DIMMs per processor or 16 DIMMs with two processors installed. Each processor has eight memory channels with one DIMM per channel. With 128 GB 3DS RDIMMs installed, the SN550 V2 supports a total of 2 TB of system memory.

The SN550 V2 also supports Intel Optane Persistent Memory 200 Series, as described in the Persistent Memory section.

Memory operates at up to 3200 MHz, depending on the processor model selected. If the processor selected has a lower memory bus speed, then all DIMMs will operate at that lower speed.

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.

4X77A08636 BA62 ThinkSystem 128GB TruDDR4 3200 MHz (2S2Rx4 1.2V) 3DS RDIMM 16 (8 per processor)

The following rules apply when selecting the memory configuration:

  • In the SN550 V2, the following DIMM quantities are supported per processor: 1, 2, 4, 6, and 8. Other quantities per processor are not supported.
  • The server supports RDIMMs and 3DS RDIMMs; UDIMMs and LRDIMMs are not supported
  • Mixing RDIMMs and 3DS RDIMMs is not supported
  • Mixing x4 and x8 DIMMs is supported

For best performance, consider the following:

  • Populate memory DIMMs in quantities of 8 per processor, so that all memory channels are used.
  • 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

Note: Memory sparing is not supported

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. Memory rank sparing is not supported.

Persistent Memory

The SN550 V2 server supports Intel Optane Persistent Memory 200 Series, a new class of memory and storage technology explicitly architected for data center usage. Persistent memory is an innovative technology that delivers a unique combination of affordable large memory capacity and persistence (non-volatility). It offers significantly lower latency than fetching data from SSDs, even NVMe SSDs, and offers higher capacities than system memory.

Persistent memory technology can help boost the performance of data-intensive applications such as in-memory analytics, databases, content delivery networks, and high performance computing (HPC), as well as deliver consistent service levels at scale with higher virtual machine and container density. 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 supported persistent memory modules.

The following are the requirements when installing persistent memory (PMem) modules when installed in a two-socket server with third-generation Intel Xeon Scalable processors ("Ice Lake" processors):

  • App Direct Mode and Memory Mode are supported. Mixed Mode is not supported.
  • All PMem modules operate at 3200 MHz when the installed processor runs the memory bus at 3200 MHz.
  • All installed PMem modules must be the same size. Mixing PMem modules of different capacities is not supported.
  • Maximum 4 PMem modules per processor.
  • Both interleaved and non-interleaved modes are supported.
  • Memory mirroring is not supported with PMem modules installed

Intel VROC onboard SATA and NVMe RAID

Intel VROC (Virtual RAID on CPU) is a feature of the Intel processor that enables RAID support. There are two separate functions of VROC:

  • Intel VROC SATA RAID, formerly known as Intel RSTe
  • Intel VROC NVMe RAID

VROC SATA RAID (RSTe) is available and supported with all SATA drives, both SATA SSDs and SATA HDDs. If offers a 6 Gb/s connection to each drive and on the SN550 V2 implements RAID levels 0, 1, 5, and 10.

VROC NVMe RAID offers RAID support for any NVMe drives directly connected to the ports on the server's system board or via adapters such as NVMe retimers or NVMe switch adapters. On the SN550 V2, it implements RAID levels 0, 1, 5, and 10.

Performance tip: For best performance with VROC NVMe RAID, the drives in an array should all be connected to the same processor. Spanning processors is supported however performance will be unpredictable and should be evaluated based on your workload.

By default, VROC NVMe RAID support is limited to use with only Intel-branded NVMe drives (feature B9X7). If you wish to enable RAID support for non-Intel NVMe SSDs, select the VROC Premium license using the ordering information in the following table. VROC Premium is fulfilled as a Feature on Demand (FoD) license and is activated via the XCC management processor user interface.

Table 16. VROC upgrade
Part number Feature code Description
4L47A39164 B96G Intel VROC (VMD NVMe RAID) Premium

VROC Premium is only needed for non-Intel NVMe drives in a RAID configuration. You do not need the VROC Premium license upgrade under any of the following conditions:

  • If you have SATA drives connected to the onboard SATA ports, you do not need VROC Premium
  • If you have Intel NVMe drives connected to the onboard NVMe ports, you do not need VROC Premium
  • If you have non-Intel NVMe drives connected to the onboard NVMe ports, but you don’t want RAID support, you do not need VROC Premium

Virtualization support: When implementing VROC RAID (SATA or NVMe), the onboard SATA and NVMe ports do not support virtualization hypervisors such as VMware ESXi, Linux KVM, Xen, and Microsoft Hyper-V. Virtualization is supported on the SATA ports only in AHCI (non-RAID) mode.

Internal drive options

The following tables list the hard disk drive and solid-state drive options for the internal disk storage of the server.

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.

Existing Flex System customers: If you configure the  SN550 V2 to have processors with a TDP of 135W or larger, then check which power supplies are installed in your existing Flex System Enterprise Chassis. If the chassis has Delta power supplies, then the processors will be capped at 125W due to an issue with the Delta power supplies. To prevent this from happening, replace the power supplies with Artesyn power supplies. All new Enterprise Chassis orders will already have the correct power supplies configured so no further action is needed.

For a discussion about quantities of servers supported based on the number of power supplies installed, see the Chassis support section.

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.

Lenovo ThinkShield - Platform Firmware Resiliency

Lenovo’s ThinkShield Security is a transparent and comprehensive approach to security that extends to all dimensions of our data center products: from development, to supply chain, and through the entire product lifecycle.

The ThinkSystem SN550 V2 offers Platform Firmware Resiliency (PFR) hardware Root of Trust (RoT) which is NIST SP800-193 compliant. This offering further enhances key platform subsystem protections against unauthorized firmware updates and corruption, to restore firmware to an integral state, and to closely monitor firmware for possible compromise from cyber attacks.

PFR operates upon the following server components:

  • UEFI image – the low level server firmware that connects the operating system to the server hardware
  • XCC image – the management “engine” software that controls and reports on the server status separate from the server operating system
  • FPGA image – the code that runs the server’s lowest level hardware controller on the motherboard

The Lenovo Platform Root of Trust Hardware performs the following three main functions:

  • Detection – Measures the firmware and updates for authenticity
  • Recovery – Recovers a corrupted image to a known-safe image
  • Protection – Monitors the system to ensure the known-good firmware is not maliciously written

These enhanced protection capabilities are implemented using a dedicated, discrete security processor whose implementation has been rigorously validated by leading third-party security firms. Security evaluation results and design details are available for customer review – providing unprecedented transparency and assurance.

Intel Transparent Supply Chain

Add a layer of protection in your data center and have peace of mind that the server hardware you bring into it is safe authentic and with documented, testable, and provable origin.

Lenovo has one of the world’s best supply chains, as ranked by Gartner Group, backed by extensive and mature supply chain security programs that exceed industry norms and US Government standards. Now we are the first Tier 1 manufacturer to offer Intel® Transparent Supply Chain in partnership with Intel, offering you an unprecedented degree of supply chain transparency and assurance.

  • Health Check

    Having a trusted partner who can perform regular and detailed health checks is central to maintaining efficiency and ensuring that your systems and business are always running at their best. Health Check supports Lenovo-branded server, storage, and networking devices, as well as select Lenovo-supported products from other vendors that are sold by Lenovo or a Lenovo-Authorized Reseller.

Examples of region-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 spare parts.

  • Assessment Services

    An Assessment helps solve your IT challenges through an onsite, multi-day session with a Lenovo technology expert. We perform a tools-based assessment which provides a comprehensive and thorough review of a company's environment and technology systems. In addition to the technology based functional requirements, the consultant also discusses and records the non-functional business requirements, challenges, and constraints. Assessments help organizations like yours, no matter how large or small, get a better return on your IT investment and overcome challenges in the ever-changing technology landscape.

  • Design Services

    Professional Services consultants perform infrastructure design and implementation planning to support your strategy. The high-level architectures provided by the assessment service are turned into low level designs and wiring diagrams, which are reviewed and approved prior to implementation. The implementation plan will demonstrate an outcome-based proposal to provide business capabilities through infrastructure with a risk-mitigated project plan.

  • Basic Hardware Installation

    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.

  • Deployment Services

    When investing in new IT infrastructures, you need to ensure your business will see quick time to value with little to no disruption. Lenovo deployments are designed by development and engineering teams who know our Products & Solutions better than anyone else, and our technicians own the process from delivery to completion. Lenovo will conduct remote preparation and planning, configure & integrate systems, validate systems, verify and update appliance firmware, train on administrative tasks, and provide post-deployment documentation. Customer’s IT teams leverage our skills to enable IT staff to transform with higher level roles and tasks.

  • Integration, Migration, and Expansion Services

    Move existing physical & virtual workloads easily, or determine technical requirements to support increased workloads while maximizing performance. Includes tuning, validation, and documenting ongoing run processes. Leverage migration assessment planning documents to perform necessary migrations.
