The following table compares the features of the supported third-generation Intel Xeon processors.

* L3 cache is 1.5 MB per core or larger. Processors with a larger L3 cache per core are marked with an *

One-processor configurations

The SR650 V2 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 V2:
https://thinksystem.lenovofiles.com/help/topic/SR650V2/thermal_rules.html?cp=4_11_7_2_1

The SR650 V2 uses Lenovo TruDDR4 memory and supports 16 DIMMs per processor or 32 DIMMs with two processors installed. Each processor has eight memory channels with two DIMMs per channel. With 128 GB 3DS RDIMMs installed, the SR650 V2 supports a total of 4 TB of system memory.

The SR650 V2 also supports Intel Optane Persistent Memory 200 Series, as described in the Persistent Memory section.

Memory operates at up to 3200 MHz at two DIMMs per channel, depending on the memory DIMMs and 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.

For best performance, consider the following:

• Populate memory DIMMs in quantities of 8 or 16 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.

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.

The SR650 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 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 not supported with PMem modules installed

For details, including App Direct Mode and Memory Mode configuration requirements, see the Intel Optane Persistent Memory 200 Series product guide, https://lenovopress.com/LP1380

The SR650 V2 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.

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
• Front drive bays
• Mid drive bays
• Rear drive bays
• Supported drive bay combinations
• Controller selections
• Field upgrades
• RAID flash power module (supercap) support
• M.2 drives
• 7mm drives
• SED encryption key management

NVMe drive support

The SR650 V2 supports NVMe drives to maximize storage performance.

• Up to 24 NVMe drives without oversubscription (that is, each x4 drive has a dedicated x4 (4 lanes) connection to the processor)
  • All installed in front bays
  • 12 drives connected to onboard NVMe ports, 12 connected to 3 retimer cards installed in PCIe x16 slots
• Up to 32 NVMe drives with a 2:1 oversubscription (that is, eight x4 drives share a x16 connection via an NVMe switch, and the switch manages the connections to maximize performance of all drives)
  • 24 NVMe drives in the front bays
  • 8 NVMe drives in the mid bays
  • All drives connected to 4 NVMe switch adapters (3 front, 1 mid)
• Up to 12 NVMe drives in a 3.5-inch drive configuration
  • All installed in front bays
  • All drives connected on onboard NVMe ports

The specifics of these configurations are covered in the Supported drive bay combinations and Controller selections sections.

The tables in those sections indicate the number of NVMe drives in each configuration plus the subscription ratio. The subscription ratio is the number of PCIe lanes from the processor compared to the number of lanes to the drives. A ratio of 1:1 means all drives get the full number of lanes they need to maximize drive performance (currently 4 lanes per drive). A ratio of 1:2 means each drive only gets the half the bandwidth from the processor. NVMe drives connected to a RAID adapter with Tri-Mode support have a 1:4 effective ratio, since they only have a 1-lane connection to the RAID adapter.

In addition, the SR650 V2 supports two 7mm NVMe drives for use as boot drives. These two drives are connected via separate RAID controller connected to a single PCIe 3.0 x2 host interface. See the 7mm drives section for details.

Tri-Mode support

These configurations are shown in the following figure. 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.

Figure 7. SR650 V2 front drive bay configurations

The backplanes used to provide these drive bays are listed in the following table.

The use of front drive bays has the following configuration rules:

• If 3.5-inch front drive bays are used, an internal 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, NVMe) can optionally be configured for use with the Integrated Diagnostics Panel. 3.5-inch drive configurations do not support the Integrated Diagnostics Panel.

Mid drive bays

The SR650 V2 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.

Figure 8. 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.

The use of drive bays in the mid-chassis area has the following configuration rules:

• Processors with TDP > 205W are not supported
• Full-length adapter cards are not supported
• GPUs (including low profile GPUs such as the T4) are not supported
• Riser 1 and Riser 2 are required, since power for the mid bay backplanes comes from Riser 2, and Riser 2 requires Riser 1 be configured
• 2 CPUs are required, since the second processor is required for Riser 2.

The backplanes used to provide these drive bays are listed in the following table.

The use of rear drive bays has the following configuration rules:

• Processors with TDP > 205W are not supported
• Riser 3 is not supported since the rear drive bays occupy the space of this riser.
• The use of rear drive 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 requires Riser 1 be installed, since power for the rear backplane comes from Riser 1
• The 7mm rear drive kit is supported installed in either slot 3 or slot 6 but not both at the same time.
• The 7mm drive enclosure is connected to an onboard port and cannot be connected to any installed RAID adapter or HBA.
