Secure Boot Policy When Secure Boot policy is set to Standard, the BIOS uses the system manufacturer’s key

and certificates to authenticate pre-boot images. When Secure Boot policy is set to Custom, the BIOS uses the user-defined key and certificates. Secure Boot policy is set to Standard by default.

Secure Boot Mode Configures how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).

If the current mode is set to Deployed Mode, the available options are User Mode and

Deployed Mode. If the current mode is set to User Mode, the available options are User Mode, Audit Mode, and Deployed Mode.

Table 33. Secure Boot Mode

Options Descriptions

User Mode

Deployed Mode

In User Mode, PK must be installed, and BIOS performs signature verification on programmatic attempts to update policy objects.

The BIOS allows unauthenticated programmatic transitions between modes.

Deployed Mode is the most secure mode. In Deployed Mode, PK must be installed and the BIOS performs signature verification on programmatic attempts to update policy objects.

Deployed Mode restricts the programmatic mode transitions.

Audit Mode

34 Pre-operating system management applications

In Audit mode, PK is not present. The BIOS does not authenticate programmatic updates to the policy objects, and transitions between modes. The BIOS performs a signature verification on pre-boot images and logs the results in the image Execution Information Table, but executes the images whether they pass or fail verification.

System memory

System memory guidelines

The PowerEdge R6525 system supports DDR4 registered DIMMs (RDIMMs) and Load Reduced DIMM (LRDIMMs). System memory holds the instructions that are started by the processor.

Your system memory is organized into eight channels per processor (two memory sockets per channel),16 memory sockets per processor and 32 memory sockets per system.

General memory module installation guidelines

To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory. If your system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during memory configuration, or operate with reduced memory. This section provides information on the memory population rules and about the nonuniform memory access (NUMA) for single or dual processor system.

The memory bus may operate at speeds of 3200 MT/s, 2933 MT/s, or 2666 MT/s depending on the following factors:

• System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])

• Maximum supported DIMM speed of the processors

• Maximum supported speed of the DIMMs

NOTE: MT/s indicates DIMM speed in MegaTransfers per second.

The system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset architectural configuration. The following are the recommended guidelines for installing memory modules:

• All DIMMs must be DDR4.

• Mixing of memory module capacities in a system is not supported.

• If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s).

• Populate memory module sockets only if a processor is installed.

• For dual-processor systems, sockets A1 to A16 and sockets B1 to B16 are available.

• In Optimizer Mode, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory performance.

Table 40. Memory population rules

Processor Configuration Memory population Memory population

Single processor Optimizer (Independent

channel) population order

Dual processor (Start with processor1. Processor 1 and processor 2 population should match)

• Populate all the sockets with white release tabs first, followed by the black release tabs.

• In a dual-processor configuration, the memory configuration for each processor must be identical.

For example, if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.

• Unbalanced or odd memory configuration results in a performance loss and system may not identify the memory modules being installed, so always populate memory channels identically with identical electrical specification DIMMs for best performance.

• Minimum recommended configuration is to populate four identical electrical specifications memory modules per processor. AMD recommends limiting processors in that system to 32 cores or less.

• Populate eight identical electrical specification memory modules per processor (one DIMM per channel) at a time to maximize performance.

Non-uniform memory access (NUMA)

Non-uniform memory access (NUMA) is a memory design used in multi-processing, where the memory access time depends on the memory location relative to the processor. In NUMA, a processor can access its own local memory faster than the non-local memory.

NUMA nodes per socket (NPS)

NUMA nodes per socket (NPS) is a new feature added that allows you to configure the memory NUMA domains per socket. The configuration can consist of one whole domain (NPS1), two domains (NPS2), or four domains (NPS4). In the case of a two-socket platform, an additional NPS profile is available to have whole system memory to be mapped as single NUMA domain (NPS0).

In the processors, each physical processor package contains multiple processor cores that are grouped together into core complexes and core complex dies. A core complex (CCX) consists of maximum four processor cores and an L3 cache memory. A core complex die (CCD) contains two CCXs. The physical processor package contains maximum eight core CCDs. A max CCD x CCX x Core processor will have 64 cores. The BIOS setup allows for the selection of an NPS profile based on down core profile and by processor SKU.

Optimizer (Independent channel) population order

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16

NOTE: If the system configuration does not support an NPS profile, the options are not displayed until the configuration

changes.

NOTE: If there is a memory training failure, configuration change, or processor swap that no longer supports a specific

NPS profile, an error message is displayed at the end of POST and logged in the LifeCycle Controller.

Interleaving option

Based on the NPSx selection, the AMD Platform Security Processor (PSP) firmware selects the corresponding preferred memory interleaving. If the memory configuration does not allow the preferred option (Example: a channel is not populated or one or more DIMMs on a channel does not initialize or train properly), the pre-BIOS firmware selects the corresponding alternate memory interleaving option.

Table 42. Interleaving Options Based on NPSx

NPSx options - Dual processor

NPSx Preferred Alternate

4 2-channel None

2 4-channel 2-channel

1 8-channel 4-channel, 2-channel

0 16-channel (dual processor) 2-channel

NOTE: In a dual processor system both sockets have to be in the same interleaving mode if both sockets have memory

populated.

Two channel interleaving (per quadrant) - NPS4 and fallback for NPS2/1/0

• This interleaves two channels in each quadrant.

• Does not require the memory to be equal on both channels of a quadrant. Any non-symmetrical DIMM is stacked on top.

• Any quadrant where one of the two channels is not populated is not interleaved.

• There is no alternate, as all configurations can be mapped into this mode.

Four channel interleaving (per half-socket) - NPS2

• This interleaves the four channels on the left or right half of a socket. As an alternative option from NPS1 only, the four channels {CS A, B, C, D} may be interleaved.

• Requires all four channels to be populated with equal size memory.

• There is no requirement that the two halves have equal size memory with respect to each other.

• The system has support for one half to have no memory.

• In a dual processor system:

• There is no requirement that both sockets have the same number of halves populated.

• There is no requirement that each of the four halves has the same amount of memory with respect to each other.

• The system allows for one of the sockets to have no memory.

Eight channel interleaving (per socket) - NPS1

• This interleaves eight channels in a socket.

NOTE:

populated as NPS2.

{CS A, B, C, D} and {CS E, F, G, H} is only recommended as a memory population if all eight channels are

72 Installing and removing system components

NOTE: It is recommended that all channels must be populated (CS A, B, C, D, E, F, G, H) for NPS1, but NPS1 does

support a 4 channel configuration of (CS C, D, G, H) but does not have optimal performance.

• Requires all populated channels in a socket to have equal size memory.

• In a dual processor system:

• There is no requirements for both sockets to have equal size memory.

• If both sockets have memory the interleaving mode must be the same for both sockets.

• The system allows for one of the sockets to have no memory.

• Single processor system creates a single NUMA node for the system, the SRAT and SLIT table are not required.

Socket interleaving (dual processor only) - NPS0

• This interleaves all 16 channels (eight per socket) in a dual processor system.

• Requires all channels in the system to be populated with equal size memory.

• Creates a single NUMA node for the system, the SRAT and SLIT table are not required.

CCX/Last-Level Cache (LLC) as NUMA domains

In addition to selecting the number of NUMA domains via NPS option, the processor allows for making memory per CCX as NUMA domain. In the processor each CCD has a maximum of two CCXs with each CCX having a shared last-level cache (LLC, or L3 cache) for all cores. The CCX as NUMA domain option allows for each LLC to be configured as a NUMA domain so that for certain workloads pinning execution to a single NUMA domain can be done.

The total amount of memory for each default NUMA node is divided by the number of CCXs within each CCD and distributed equally to each new per-CCX. The max number of NUMA domains generated will based on how many CCD and CCX are fused for that processor SKU.
