Topics in this section:

• CTO models
• Base feature codes
• Preconfigured models

CTO models

ThinkSystem SR630 V3 models can be configured by using the Lenovo Data Center Solution Configurator (DCSC).

Configure-to-order (CTO) models are used to create models with factory-integrated server customizations. For CTO models, two types of base CTO models are available for the SR630 V3 as listed in the columns in the following table:

• General purpose base CTO models are for general business (non-HPC) and is selectable by choosing General Purpose mode in DCSC.
• AI and HPC base models are intended for Artificial Intelligence (AI) and High Performance Computing (HPC) configurations and solutions are enabled using the AI & HPC Hardware - ThinkSystem Hardware mode in DCSC. These configurations, along with Lenovo EveryScale Solutions, can also be built using System x and Cluster Solutions Configurator (x-config). Tip: Some HPC and AI models are not listed in DCSC and can only be configured in x-config.

Preconfigured server models may also be available for the SR630 V3, however these are region-specific; that is, each region may define their own server models, and not all server models are available in every region.

The following table lists the base CTO models of the ThinkSystem SR630 V3 server.

Base feature codes

Models of the SR630 V3 are defined based on whether the server has 2.5-inch drive bays at the front (called the 10x 2.5" chassis or simply the 2.5-inch chassis) or whether it has 3.5-inch drive bays at the front (called the 3.5-inch chassis). For models, the feature codes for these chassis bases are as listed in the following table.

Preconfigured models

The following tables list the available preconfigured models, grouped by region.

• Models for Asia Pacific region
• Models for Australia and New Zealand
• Models for Brazil
• Models for EMEA region
• Models for India
• Models for Japan
• Models for Latin American countries (except Brazil)
• Models for USA and Canada

Refer to the Specifications section for information about standard features of the server.

The SR630 V3 supports processors in the 4th Gen Intel Xeon Scalable Processor family. The server supports one or two processors.

Topics in this section:

• Processor options
• Processor features
• Intel On Demand feature licensing
• One-processor configurations
• Thermal requirements by processor
• Lenovo Neptune Liquid to Air Module - Closed-loop liquid cooling
• Lenovo Processor Neptune Core Module - Open-loop liquid cooling
• UEFI operating modes

Configuration notes:

• Processor options include a heatsink but do not include a system fan

• Intel Dynamic Load Balancer (Intel DLB)

  Improve the system performance related to handling network data on multi-core Intel Xeon Scalable processors. Intel Dynamic Load Balancer (Intel DLB) enables the efficient distribution of network processing across multiple CPU cores/threads and dynamically distributes network data across multiple CPU cores for processing as the system load varies. Intel DLB also restores the order of networking data packets processed simultaneously on CPU cores.

• Intel Data Streaming Accelerator (Intel DSA)

  Drive high performance for storage, networking, and data-intensive workloads by improving streaming data movement and transformation operations. Intel Data Streaming Accelerator (Intel DSA) is designed to offload the most common data movement tasks that cause overhead in data center-scale deployments. Intel DSA helps speed up data movement across the CPU, memory, and caches, as well as all attached memory, storage, and network devices.

• Intel In-Memory Analytics Accelerator (Intel IAA)

  Run database and analytics workloads faster, with potentially greater power efficiency. Intel In-Memory Analytics Accelerator (Intel IAA) increases query throughput and decreases the memory footprint for in-memory database and big data analytics workloads. Intel IAA is ideal for in-memory databases, open source databases and data stores like RocksDB, Redis, Cassandra, and MySQL.

• Intel Advanced Matrix Extensions (Intel AMX)

  Intel Advanced Matrix Extensions (Intel AMX) is a built-in accelerator in all Silver, Gold, and Platinum processors that significantly improves deep learning training and inference. With Intel AMX, you can fine-tune deep learning models or train small to medium models in just minutes. Intel AMX offers discrete accelerator performance without added hardware and complexity.

The processors also support a separate and encrypted memory space, known as the SGX Enclave, for use by Intel Software Guard Extensions (SGX). The size of the SGX Enclave supported varies by processor model. Intel SGX offers hardware-based memory encryption that isolates specific application code and data in memory. It allows user-level code to allocate private regions of memory (enclaves) which are designed to be protected from processes running at higher privilege levels.

The following table summarizes the key features of all supported 5th Gen processors in the SR630 V3.

The following table summarizes the key features of all supported 4th Gen processors in the SR630 V3.

See the Processor features section for a brief description of each accelerator and the SGX Enclave.

The following table lists the ordering information for the licenses. Accelerator licenses are bundled together based on the suitable workloads each would benefit with the additional accelerators.

Licenses can be activated in the factory (CTO orders) using feature codes, or as field upgrades using the option part numbers. With the field upgrades, they allow customers to only activate the accelerators or to increase the SGX Enclave size when their applications can best take advantage of them.

Intel On Demand is licensed on individual processors. For servers with two processors, customers will need a license for each processor and the licenses of the two processors must match. If customers add a second processor as a field upgrade, then you must ensure that the Intel On Demand licenses match the first processor.

Each license enables a certain quantity of embedded accelerators - the total number of accelerators available after activation is listed in the table. For example, Intel On Demand Communications & Storage Suite 4 (4L47A89451), once applied to the server, will result in a total of 4x QAT, 4x DLB and 4x DSA accelerators to be enabled the processor. The number of IAA accelerators is unchanged in this example.

The following table lists the 5th Gen processors that support Intel on Demand. The table shows the default accelerators and default SGX Enclave size, and it shows (with green highlight) what the total new accelerators and SGX Enclave would be once the Intel On Demand features have been activated.

The following table lists the 4th Gen processors that support Intel on Demand. The table shows the default accelerators and default SGX Enclave size, and it shows (with green highlight) what the total new accelerators and SGX Enclave would be once the Intel On Demand features have been activated.

Configuration rules:

• Not all processors support Intel On Demand upgrades - see the table for those that do not support Intel On Demand
• Upgrades can be performed in the factory (feature codes) or in the field (part numbers) but not both, and only one time
• Upgrades cannot be removed once activated
• SGX Enclave upgrades are independent of the accelerator upgrades; install either or both as desired
• For processors that support more than one upgrade, all upgrades must be performed at the same time
• Only one of each type of upgrade can be applied to a processor (eg 2x BX9A is not supported; 4x BX9B is not supported)
• The following processors support two accelerator upgrades, Intel On Demand Analytics Suite 4 (4L47A89452) and Intel On Demand Communications & Storage Suite 4 (4L47A89451); the table(s) above shows the accelerators based on both upgrades being applied.
  • Intel Xeon Platinum 8460Y+
  • Intel Xeon Platinum 8480+
  • Intel Xeon Platinum 8568Y+
  • Intel Xeon Platinum 8592+
• The number of accelerators listed for each upgrade is the number of accelerators that will be active one the upgrade is complete (ie the total number, not the number to be added)
• If a server has two processors, then two feature codes must be selected, one for each processor. The upgrades on the two processors must be identical.
• If a one-processor server with Intel On Demand features activated on it has a 2nd processor added as a field upgrade, the 2nd processor must also have the same features activated by purchasing the appropriate part numbers.

For additional thermal requirements for processors, see the Thermal Rules section in the Lenovo Docs site for the SR630 V3:
https://pubs.lenovo.com/sr630-v3/thermal_rules

The SR630 V3 supports four different processor cooling solutions, depending on the configuration, as listed in the following table.

The selection of the heatsink will be automatically derived by the configurator and depends on the processor and other components selected. Use the tables in the Lenovo Docs site to determine the requirements for each heatsink:
https://pubs.lenovo.com/sr630-v3/thermal_rules

Lenovo Neptune Liquid to Air Module - Closed-loop liquid cooling

The Lenovo Neptune Liquid to Air (L2A) Module is a closed-loop liquid-cooled processor heatsink, and is primarily used for processors with a TDP of more than 300W. Without the closed-loop heatsink, the use of processors > 300W TDP requires that only 4x front 2.5-inch drive bays be configured. The use of the closed-loop heatsink allows for 10x SAS/SATA or NVMe drives bays.

The following figure shows the placement of the components in the closed-loop liquid-cooled solution. Cold plates are mounted on top of each processor and these are connected via aluminum tubes to a radiator that is placed in front of the system fans. The tubes contain a mixture of water and ethylene glycol (EGW). The liquid is actively pumped through the pipes in a closed loop to remove the heat from the processors.

Figure 7. SR630 V3 with Neptune Liquid to Air Module

The Neptune Liquid to Air Module is only available in CTO orders, not as a field upgrade. Ordering information is listed in the following table.

The closed-loop liquid-cooled heatsink has the following requirements:

• Either one or two CPUs are supported
• One of the following 2.5-inch front drive bay configurations:
  • 10x 2.5'' SAS/SATA
  • 10x 2.5'' NVMe
  • 6x SAS/SATA + 2x AnyBay + 2x NVMe
  • 6x SAS/SATA + 4x AnyBay
  • 8x 2.5'' SAS/SATA
  • 8x 2.5'' U.2 drives with one processor
• 3.5-inch and EDSFF front drive bays are not supported

Lenovo Processor Neptune Core Module - Open-loop liquid cooling

The SR630 V3 also supports advanced direct-water cooling (DWC) capability with the Lenovo Processor Neptune Core Module. This module implements a liquid cooling solution where heat from the processors is removed from the rack and the data center using an open loop and coolant distrubution units.

With the Processor Neptune Core Module, all heat generated by the processors is removed from the server using water. This means that the server fans and data center air conditioning units only need to remove the heat generated by the other components. This results in lower air conditioning costs and it enables the use of slower fans which results in lower overall power consumption.

Typical power saving of 26% (up to 17.2KW per rack) are possible, based on 35x SR630 V3 servers in a rack (DC level PUE weighted) at 30°C ambient temperature. Power savings are configuration dependent.

The following figure shows the Lenovo Processor Neptune Core Module.

Figure 8. Lenovo Processor Neptune Core Module

The Processor Neptune Core Module also includes a leak detection module which can detect a leakage of more than 0.5ml (about 10 drops) along the length of the tube and then issue an event to the XClarity Controller. XCC will then post an error to the System Event Log and enable further actions. Once the liquid evaporates, a further event is issue to XCC.

The Processor Neptune Core Module is only available in CTO orders, not as a field upgrade. Ordering information is listed in the following table.

Configuration notes:

• The Processor Neptune Core Module requires water infrastructure be available in the rack cabinet and data center, as described in the Water infrastructure section.
