Intel On Demand feature licensing
Intel On Demand is a licensing offering from Lenovo for certain 4th Gen and 5th Gen Intel Xeon Scalable processors that implements software-defined silicon (SDSi) features. The licenses allow customers to activate the embedded accelerators and to increase the SGX Enclave size in specific processor models as their workload and business needs change.
The available upgrades are the following:
- Up to 4x QuickAssist Technology (Intel QAT) accelerators
- Up to 4x Intel Dynamic Load Balancer (Intel DLB) accelerators
- Up to 4x Intel Data Streaming Accelerator (Intel DSA) accelerators
- Up to 4x Intel In-Memory Analytics Accelerator (Intel IAA) accelerators
- 512GB SGX Enclave, an encrypted memory space for use by Intel Software Guard Extensions (SGX)
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.
One-processor configurations
The SR650 V3 can be used with only one processor installed. Most core functions of the server (including the XClarity Controller) are connected to processor 1 as shown in the System architecture section.

Thermal requirements for processors
For thermal requirements for processors, see the Thermal Rules section in the Information Center for the SR650 V3:
https://pubs.lenovo.com/sr650-v3/thermal_rules
Lenovo Processor Neptune Core Module - Open-loop liquid cooling
The SR650 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 23% (up to 9.9KW per rack) are possible, based on 18x SR650 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 7. 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.
| Part number | Feature code | Description |
|---|---|---|
| CTO only | BXBC* | ThinkSystem V3 1U/2U Neptune Processor Direct Water Cooling Solution |
* In DCSC, this feature code is listed in the Processor tab
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.
- All processor SKUs are supported
- Either one or two CPUs are supported
- All front drive bay configurations are supported
- Slot 6 is not available for adapters - the water loop is routed through the space otherwise occupied by slot 6
- Rear drive bays are supported
- 7mm drive bays are supported only in slot 3
- M.2 adapters are supported based on the configurations in the Storage configurations section
- Standard fans can be configured in most configurations
- The use of a cable management arm (CMA) is not supported
For more information, see the Thermal Rules page:

UEFI operating modes
The SR650 V3 offers preset operating modes that affect energy consumption and performance. These modes are a collection of predefined low-level UEFI settings that simplify the task of tuning the server to suit your business and workload requirements.
The following table lists the feature codes that allow you to specify the mode you wish to preset in the factory for CTO orders.
UK and EU customers: For compliance with the ERP Lot9 regulation, you should select feature BFYE. For some systems, you may not be able to make a selection, in which case, it will be automatically derived by the configurator.
The preset modes for the SR650 V3 are as follows:
- Maximum Performance Mode (feature BFYB): Achieves maximum performance but with higher power consumption and lower energy efficiency.
- Minimal Power Mode (feature BFYC): Minimize the absolute power consumption of the system.
- Efficiency Favoring Power Savings Mode (feature BFYD): Maximize the performance/watt efficiency with a bias towards power savings. This is the favored mode for SPECpower benchmark testing, for example.
- Efficiency Favoring Performance Mode (feature BFYE): Maximize the performance/watt efficiency with a bias towards performance. This is the favored mode for Energy Star certification, for example.
For details about these preset modes, and all other performance and power efficiency UEFI settings offered in the SR650 V3, see the paper "Tuning UEFI Settings for Performance and Energy Efficiency on Intel Xeon Scalable Processor-Based ThinkSystem Servers", available from https://lenovopress.lenovo.com/lp1477.
Memory options
The SR650 V3 uses Lenovo TruDDR5 memory operating at up to 5600 MHz. The server supports up to 32 DIMMs with 2 processors. The processors have 8 memory channels and support 2 DIMMs per channel (DPC). The server supports up to 8TB of memory using 32x 256GB 3DS RDIMMs and two processors.
With 5th Gen Intel Xeon processors, DIMMs operate at the following speeds, up to the memory bus speed of the processor selected. See the Processor features section for specifics.
- 1 DIMM per channel (DPC) using RDIMMs: Up to 5600 MHz
- 1 DPC using 3DS RDIMMs: Up to 5200 MHz
- 2 DPC using RDIMMs or 3DS RDIMMs: Up to 4400 MHz
- 2 DPC using Performance+ RDIMMs: Up to 4800 MHz
With 4th Gen Intel Xeon processors, DIMMs operate at the following speeds, up to the memory bus speed of the processor selected:
- 1 DPC: Up to 4800 MHz
- 2 DPC: Up to 4400 MHz
Lenovo TruDDR5 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 TruDDR5 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.
The following table lists the 5600 MHz memory options that are currently supported by the SR650 V3. These DIMMs are only supported with 5th Gen Intel Xeon processors, except the four specific 5th Gen processors listed in the memory rules below.
The following table lists the 4800 MHz memory options that are currently supported by the SR650 V3. These DIMMs are only supported with 4th Gen Intel Xeon processors plus four specific 5th Gen processors as listed in the memory rules below.
9x4 RDIMMs (also known as EC4 RDIMMs) are a new lower-cost DDR5 memory option supported in ThinkSystem V3 servers. 9x4 DIMMs offer the same performance as standard RDIMMs (known as 10x4 or EC8 modules), however they support lower fault-tolerance characteristics. Standard RDIMMs and 3DS RDIMMs support two 40-bit subchannels (that is, a total of 80 bits), whereas 9x4 RDIMMs support two 36-bit subchannels (a total of 72 bits). The extra bits in the subchannels allow standard RDIMMs and 3DS RDIMMs to support Single Device Data Correction (SDDC), however 9x4 RDIMMs do not support SDDC. Note, however, that all DDR5 DIMMs, including 9x4 RDIMMs, support Bounded Fault correction, which enables the server to correct most common types of DRAM failures.
For more information on DDR5 memory, see the Lenovo Press paper, Introduction to DDR5 Memory, available from https://lenovopress.com/lp1618.
The following rules apply when selecting the memory configuration:
- 4800 MHz memory is only supported with 4th Gen Intel Xeon Scalable processors. 5600 MHz memory is only supported with 5th Gen Intel Xeon Scalable processors, with only four exceptions as listed below.

- Ensure the memory installed is at least the same speed as the memory bus of the selected processor.
- Populate all 8 memory channels.
The following memory protection technologies are supported:
- ECC detection/correction
- Bounded Fault detection/correction
- SDDC (for 10x4-based memory DIMMs; look for "x4" in the DIMM description)
- ADDDC (for 10x4-based memory DIMMs, not supported with 9x4 DIMMs)
- Memory mirroring
See the Lenovo Press article "RAS Features of the Lenovo ThinkSystem Intel Servers" for more information about memory RAS features: https://lenovopress.lenovo.com/lp1711-ras-features-of-the-lenovo-thinksystem-intel-servers
If memory channel mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per processor), and both DIMMs in the pair 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 SR650 V3 server supports Intel Optane Persistent Memory 300 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.
Key workloads:
- Hybrid cloud, IaaS, and Virtualization: Increased VM density
- In-memory databases and data services: Higher capacity/larger databases, data reliability/quick recovery, memory performance
- AI/Analytics: Faster real-time analytics and Machine Learning Analytics
- Fast storage solutions: Increased storage capacity and 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:
- Only App Direct Mode is supported; Memory Mode and Mixed Mode are not supported
- All PMem modules operate at a maximum speed of 4400 MHz; any installed RDIMMs will also run at this maximum speed
- PMem is supported only with 10x4 RDIMMs and 3DS RDIMMs; PMem is not supported with 9x4 RDIMMs
- All installed PMem modules must be the same size; Mixing PMem modules of different capacities is not supported
- Maximum 8 PMem modules per processor (install 1 in each memory channel).
- For each memory channel with both a PMem module and a memory DIMM installed, the PMem module is installed in channel slot 1 (DIMM1, closer to the processor) and the DIMM is installed in channel slot 0 (DIMM0)
- To maximize performance, balance all memory channels
- Both interleaved and non-interleaved modes are supported
- Memory mirroring is only supported on the RDIMMs; Memory mirroring is not supported on the PMem modules
Internal storage
The SR650 V3 has three drive bay zones and supports up to 20x 3.5-inch or 40x 2.5-inch hot-swap drive bays or a combination of drive bays, depending on the selected chassis and backplane configuration. The server also supports configurations without any drive bays if desired.
The three drive bay zones are as follows:
- Front:
- Up to 12x 3.5-inch hot-swap bays, or
- Up to 24x 2.5-inch hot-swap bays
- Middle:
- 4x 3.5-inch hot-swap bays, or
- 8x 2.5-inch hot-swap bays
- Rear:
- Up to 4x 3.5-inch hot-swap bays, or
- Up to 8x 2.5-inch hot-swap bays
- Also supports 2x 7mm hot-swap drives bays
All drives are hot-swap and are accessible from the front, from the rear, or from drive bays that are located in the middle of the server (accessible when you remove the top cover of the server).
The server also supports one or two M.2 drives, installed in an M.2 adapter internal to the server.
In this section:
NVMe drive support
The SR650 V3 supports NVMe drives to maximize storage performance.
- Up to 36 NVMe drives in a 2.5-inch drive configuration, without oversubscription (that is, each x4 drive has a dedicated x4 (4 lanes) connection to the processor, either direct to the processor or via a retimer adapter)
- Up to 24 installed in front bays
- Up to 28 installed in the front and rear bays
- Up to 32 installed in front and mid bays
- Up to 36 installed in front, mid and rear bays
- Up to 8 NVMe drives in a 3.5-inch drive configuration, without oversubscription
- All installed in mid bays
Riser 3 support: The use of the onboard NVMe ports is mutually exclusive with Riser 3, as these use the same PCIe connectors. See the System architecture section.
The specifics of these configurations are covered in the Storage configurations section. The tables in those sections indicate the number of NVMe drives in each configuration.
In addition, the SR650 V3 supports two 7mm NVMe drives for use as boot drives. These two drives optionally support RAID via Intel VROC.
The RAID 940-8i and RAID 940-16i adapters also support NVMe through a feature named Tri-Mode support (or Trimode support). This feature enables the use of NVMe U.3 drives at the same time as SAS and SATA drives. Tri-Mode requires an AnyBay backplane. Cabling of the controller to the backplanes is the same as with SAS/SATA drives, and the NVMe drives are connected via a PCIe x1 link to the controller.
NVMe drives connected using Tri-Mode support provide better performance than SAS or SATA drives: A SATA SSD has a data rate of 6Gbps, a SAS SSD has a data rate of 12Gbps, whereas an NVMe U.3 Gen 4 SSD with a PCIe x1 link will have a data rate of 16Gbps. NVMe drives typically also have lower latency and higher IOPS compared to SAS and SATA drives. Tri-Mode is supported with U.3 NVMe drives and requires an AnyBay backplane.
Tri-Mode requires U.3 drives: Only NVMe drives with a U.3 interface are supported. U.2 drives are not supported. See the Internal drive options section for the U.3 drives supported by the server.
Front drive bays
The front drive bay zone supports the following configurations:
- 8x or 12x 3.5-inch drive bays (all hot-swap)
- 8x, 16x or 24x 2.5-inch drive bays (all hot-swap)
- 4x 2.5-inch drive bays (all hot-swap) with support for front PCIe slots
- No backplanes and no drives (supports field upgrades)
The specific combinations that are supported in the SR650 V3 are shown in the following figures. The feature codes listed are the backplane feature codes when ordering CTO and correspond to the feature codes listed in the table below the figure. Note that NVMe and AnyBay backplanes may be available either PCIe Gen4 (G4) or PCIe Gen5 (G5) as listed in the figures.
Figure 9. SR650 V3 front drive bay configurations - 3.5-inch drive bays
Figure 10. SR650 V3 front drive bay configurations - 2.5-inch drive bays, all the same drive type
Figure 11. SR650 V3 front drive bay configurations - 2.5-inch drive bays, combinations
Figure 12. SR650 V3 front drive bay configurations - 2.5-inch drive bays with front PCIe slots
The backplanes used to provide these drive bays are listed in the following table.
Field upgrades: All front backplanes are available as part numbers for field upgrades along with require cable option kits, as described in the Field upgrades section below.
* Backplane has an onboard SAS expander that provides connectivity to front SAS/SATA drive bays using only an 8-port controller, plus support for 4x rear drives in a separate backplane (order the rear backplane separately). See below for additional information and requirements.
The use of front drive bays has the following configuration rules:
- The SR650 V3 also supports configurations without any drive bays, allowing for drive bay upgrades as described in the field upgrades section.
- Most backplanes require connections to controllers that provides enough ports to connect each drive (eg 8 ports for an 8-bay backplane). The only exceptions to that are the backplanes with built-in SAS expanders - these backplanes require a fewer number of controller ports to connect to the front drives, and also include a connection to up to 4x rear drive bays. Connections to mid-chassis backplanes or to 8x rear drive bays require additional controller ports. Supported connections are as follows:
- For the ThinkSystem 2U 12x3.5" SAS/SATA with Rear 4-Bay Expander Backplane, feature BQ2S:
- 12x3.5" front drives only: requires a single 8i controller
- 12x3.5” + 4x3.5” (Rear): requires a single 8i controller, 8i to front+rear
- 12x3.5” + 4x3.5” (Mid): requires 16i controller - 8i to front, 8i to middle
- 12x3.5” + 4x3.5” (Mid) + 4x3.5” (Rear): requires 16i controller, 8i to front+rear, 8i to middle
- For the ThinkSystem 2U 24x2.5" SAS/SATA with Rear 4-Bay Expander Backplane, feature BQ2T:
- 24x2.5” front drives only: requires a single 8i controller
- 24x2.5” + 4x2.5” (Rear): requires a single 8i controller, 8i to front+rear
- 24x2.5” + 8x2.5” (Mid): requires 16i controller - 8i to front, 8i to middle
- 24x2.5” + 8x2.5” (Mid) + 8x2.5” (Rear): requires 32i controller - 8i to front, 8i to middle, 8i to rear
For specifics configurations, see the Storage configurations section.
- For the ThinkSystem 2U 12x3.5" SAS/SATA with Rear 4-Bay Expander Backplane, feature BQ2S:
- If you are building a server configuration that includes the ThinkSystem 2U 24x2.5" SAS/SATA with Rear 4-Bay Expander Backplane (feature BQ2T) and the order also includes a rack cabinet, then you can configure at most 6 drives to be installed in the factory. The remaining drives must be ordered separately using the option part numbers for the drives. This requirement does not apply if the order does not include a rack cabinet. The requirement is due to the shock/vibration limits of the 24x 2.5-inch backplane.
- If 3.5-inch front drive bays are used, an internal (CFF) RAID adapter or HBA is not supported as the adapter and bays occupy the same physical space
- Any 8x 2.5-inch and 16x 2.5-inch drive configuration (SAS/SATA, AnyBay, or NVMe) can optionally be configured for use with the Integrated Diagnostics Panel as described in the Local management section. 3.5-inch drive configurations do not support the Integrated Diagnostics Panel. With the Integrated Diagnostics Display, 8-bay configurations can be upgrade to 16 bays, however 16-bay configurations cannot be upgrade to 24 bays.
Mid drive bays
The SR650 V3 supports hot-swap drives installed in the middle of the server chassis. The drive bays are accessible by removing the top lid of the server and levering the mid drive chassis up at the front.
The following configurations are supported:
- 4x 3.5-inch hot-swap SAS/SATA drive bays
- 8x 2.5-inch hot-swap SAS/SATA drive bays
- 8x 2.5-inch hot-swap NVMe drive bays
The drive bays in the open position are shown in the following figure.
M.2 support: When mid drive bays are configured, the M.2 adapter is installed on the mid drive bay mechanical as shown in the images.
Figure 13. Mid-chassis drive bays
The backplanes used to provide these drive bays are listed in the following table.
‡ 2.5-inch drive backplanes for the mid-chassis area must be installed in pairs. NVMe and SAS/SATA cannot be mixed.
Field upgrades: Backplanes are available as part numbers for field upgrades along with require cable option kits, as described in the Field upgrades section below.
The use of drive bays in the mid-chassis area has the following configuration rules:
- All processors are supported. Higher TDP processors will require the performance heatsinks.
- Full-length adapter cards are not supported
- GPUs (including low profile GPUs such as the NVIDIA A2) are not supported
- The use of mid drive bays requires Riser 1 be installed, since power for the mid bay backplanes comes from Riser 1
Rear drive bays
The SR650 V3 supports hot-swap drives installed at the rear of the server chassis. Supported configurations are as follows:
- 3.5-inch hot-swap drives
- 2x SAS/SATA drive bays
- 4x SAS/SATA drive bays
- 2.5-inch hot-swap drives
- 4x SAS/SATA drive bays
- 4x NVMe Gen5 drive bays
- 4x AnyBay Gen5 drive bays
- 8x SAS/SATA drive bays
The configurations are shown in the following figure.
Figure 14. Rear 2.5-inch and 3.5-inch drive bay configurations
The backplanes used to provide these drive bays are listed in the following table.
7mm drives: The SR650 V3 supports two 7mm drives. See the 7mm drives section for details.
Field upgrades: Backplanes are available as part numbers for field upgrades along with require cable option kits, as described in the Field upgrades section below.
The use of rear drive bays has the following configuration rules:
- The use of rear bays restricts the number of slots and the choice of risers that are supported. See the I/O expansion section for details.
- The use of rear drive bays may require that Riser 1 or Riser 2 be installed, since power for the rear backplane comes from that riser.
- Configurations with 4x 2.5-inch rear drive bays are not supported with 7mm drive bays, as they use the same power connector
Storage configurations
This section describes the various combinations of front and rear drives that the server supports, as well as M.2 support.
Tip: These tables are based on Config Matrix V4.9 in TRD V3.51
In this section:
- Overview of configurations - 3.5-inch front drive bays
- Overview of configurations - 2.5-inch front drives supporting rear slots (no front PCIe slots)
