Processors
The SR250 supports one processor from the Intel product family formerly known by the codename “Coffee Lake-S Refresh”. This includes processors from the Intel Xeon E, Core i3, Pentium Gold, and Celeron G families. The server supports the processors that are listed in the following table.

Integrated graphics and management: Xeon processors with a G suffix include integrated graphics, however, this functionality is not used in the SR250. Instead, graphics support is provided by XClarity Controller (XCC), or by an GPU add-in card. Similarly system management of the SR250 is handled by XCC and as a result, the AMT management processor is disabled.

Memory
The SR250 server supports up to 4 TruDDR4 memory UDIMMs with ECC protection. The processor has two memory channels with two DIMMs per channel. Lenovo TruDDR4 memory uses the highest-quality components sourced from Tier 1 DRAM suppliers and only memory that meets strict requirements is selected. It is compatibility tested and tuned on every ThinkSystem server to maximize performance and reliability. TruDDR4 memory has a unique signature programmed into the DIMM, which enables Lenovo servers to verify whether the memory installed is qualified and supported. Lenovo qualified and supported TruDDR4 memory is covered by Lenovo warranty, and service and support provided worldwide.
The following rules apply when selecting the memory configuration:

The server supports memory configurations with 1, 2, 3, or 4 UDIMMs.
Mixing UDIMMs of different capacity is not supported.
All DIMMs in the server operate at the same speed up to 2666 MHz, which is determined by the maximum memory speed supported by the specific processor (see Processors for details).
Note: Maximum memory speed can be achieved when Max performance mode is enabled in UEFI.
The server supports up to 128 GB of memory.
Note: 32 GB UDIMMs are supported only with the Intel Xeon E Series processors; Core i3, Pentium Gold, and Celeron G Series processors do not support 32 GB UDIMMs.

Some regions might have different warranty terms and conditions than the standard warranty. This is due to local business practices or laws in the specific region. Local service teams can assist in explaining regionspecific terms when needed. 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. Partsonly 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. Lenovo support services are region-specific. Not all support services are available in every region. For information about Lenovo support services that are available in a specific region, refer to the following resources:

Services

Lenovo Services is a dedicated partner to customer success. Lenovo’s goal for customers is to reduce capitaloutlays, mitigate IT risks, and accelerate time to productivity.
Here is a more in-depth look at what Lenovo can do for their customers:

Asset Recovery Services
Asset Recovery Services (ARS) helps customers recover the maximum value from their end-of-life equipment in a cost-effective and secure way. On top of simplifying the transition from old to new equipment, ARS mitigates environmental and data security risks associated with data center equipment disposal. Lenovo ARS is a cash-back solution for equipment based on its remaining market value, yielding maximum value from aging assets and lowering total cost of ownership for customers. For more information, see the ARS page, http://lenovopress.com/lp1266.
Assessment Services
An assessment helps solve customer IT challenges through an onsite, multi-day session with a Lenovo technology expert. Lenovo performs 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, no matter how large or
small, get a better return on their IT investment and overcome challenges in the ever-changing
technology landscape.
Design Services
Professional Services consultants perform infrastructure design and implementation planning to support customer’s 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 customer’s server, storage, or networking hardware. Working at a time convenient for the customer (business hours or off shift), the technician will unpack and inspect the systems on customer 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 customers to focus on other priorities.
Deployment Services
When investing in new IT infrastructures, customers need to ensure that their business will see quick time to value with little to no disruption. Lenovo deployments are designed by development and engineering teams who know Lenovo products and solutions better than anyone else, and Lenovo technicians own the process from delivery to completion. Lenovo will conduct remote preparation and planning, configure and integrate systems, validate systems, verify and update appliance firmware, train on administrative tasks, and provide post- deployment documentation. Customer’s IT teams leverage Lenovo skills to enable IT staff to transform with higher level roles and tasks.
Integration, Migration, and Expansion Services
Integration, Migration, and Expansion Services allow to move existing physical and virtual workloads easily, or to determine technical requirements to support increased workloads while maximizing performance. These services include tuning, validation, and documenting ongoing run processes, and they leverage migration assessment planning documents to perform necessary migrations.

Some service options may not be available in every region. For more information about Lenovo service offerings that are available in a specific region, contact a local Lenovo sales representative or business partner.
