Memory RAS Configuration

Memory RAS Configuration

This topic describes how to configure a memory module on the Memory RAS Configuration screen.

On the Memory RAS Configuration screen, you can configure a memory module, including enabling the memory module, setting a mask, and configuring interleaved memory.

Table 4-22 describes the parameters for the IvyBridge platform. Figure 4-23 shows the Memory RAS Configuration screen.

Figure 4-23 Memory RAS Configuration screen

Table 4-22 Parameters on the Memory RAS Configuration screen

Parameter

Description

Default Value

Memory Thermal Throttling

Indicates whether to enable the function for adjusting memory temperature. The options are as follows:

  • Enable
  • Disable

Enable

NUMA

Non-Uniform Memory Acccess (NUMA) is an optimized memory access technology for OSs. It allows a processor to access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors).

Value:

  • ON (1-way): enables NUMA and allows memory to be interleaved and mapped in the unit of the memory space.
  • ON (2-way): enables NUMA and allows memory to be interleaved and mapped in the unit of 64 MB.
  • OFF (4-Way): disables NUMA and allows memory to be interleaved across two CPUs.
  • OFF (8-Way): disables NUMA and allows memory to be interleaved across four CPUs.

ON (2-way)

Memory Migration

Indicates whether to enable the memory migration function. The options are as follows:

  • Enable
  • Disable
NOTE:

If Memory Migration is enabled, the Migration Spare MC0 and Migration Spare MC1 parameters are displayed. However, the specific parameters displayed vary depending on the server model:

  • For an RH5885H V3 server, Spare Riser1 to Spare Riser8 are displayed under Migration Spare.
  • For an RH8100 V3 server:
  • Single-system mode: Board 1 to Board 16 are displayed under Migration Spare.
  • Dual-system mode: Board 1 to Board 8 are displayed under Migration Spare for system A, and Board 9 to Board 16 are displayed for system B.

Disable

Device Tagging

Indicates whether to enable the Single Device Data Correction (SDDC) function. The options are as follows:

  • Enable: If the number of correctable errors on a rank exceeds the upper limit, invalid data chips are replaced with error checking and correcting (ECC) chips. As a result, the memory loses the ability to correct ECC single-bit errors and can only detect errors.
  • Disable

Enable

DDDC Support

Indicates whether to enable the Double Device Data Correction (DDDC) function. The options are as follows:

  • Enable: DDDC supports only x4-chip DIMMs in lockstep mode. Memory chip replacement can be performed twice when a DIMM error occurs.
  • Disable
NOTE:

DDDC Wirekill and DDDC Wirekill Threshold are displayed only when DDDC Support is set to Enable.

Disable

Memory Rank Sparing

Configures memory rank sparing. In the Rank Sparing mode, one rank is used as the standby rank for other ranks in the same channel. The standby rank is reserved and does not serve as the system memory. The memory of the standby rank must be greater than or equal to that of all other ranks in the same channel. After memory rank sparing is enabled, the memory of the standby rank is not included in the calculation of the total available capacity.

The options for the RH8100 V3 server are as follows:

  • Auto: indicates that the system automatically uses rank 0 of each channel as the spare rank.
  • Manu: indicates that memory rank sparing is enabled and that you can manually set the spare rank of each channel.
  • Disable: indicates that memory rank sparing is disabled.
NOTE:
  • When Memory Rank Sparing is set to Manu:
  • MemRiser1 Spare to MemRiser16 Spare are displayed in single-system mode.
  • MemRiser1 Spare to MemRiser8 Spare are displayed for system A in dual-system mode.
  • MemRiser9 Spare to MemRiser16 Spare are displayed for system B in dual-system mode.
  • Socket 0 Branch 0 Spare Dimm to Socket 3 Branch 1 Spare Dimm are unavailable for the RH8100 V3 server.

The options for other servers are as follows:

  • Enable
  • Disable
NOTE:

Socket 0 Branch 0 Spare Dimm to Socket 3 Branch 1 Spare Dimm are displayed only when Memory Rank Sparing is set to Enable.

Disable

MemRiser1 Spare (available only for the RH8100 V3 server)

Indicates whether to enable the rank sparing function for memory riser 1 (Socket0 Branch0). The options are as follows:

  • Enable
  • Disable

The parameters MemRiser2 Spare to MemRiser16 Spare have similar meanings to MemRiser1 Spare.

The parameters MemRiser1 CH0 Spare Rank to MemRiser1 CH3 Spare Rank are displayed only when MemRiser1 Spare is set to Enable. This rule also applies to MemRiser2 Spare to MemRiser16 Spare.

Disable

MemRiser1 CH0 Spare Rank (available only for the RH8100 V3 server)

Spare rank for MemRiser1 CH0. The options are as follows:

  • Auto: indicates that the system automatically uses the largest rank as the spare rank.
  • Rank0
  • Rank1
  • Rank2
  • Rank3
  • Rank4
  • Rank5
  • Rank6
  • Rank7

Auto

Spare Error/Memory Correctable Threshold

Spare error threshold.

RH8100 V3: 20

Other servers: 32767

Memory Mirroring

Indicates whether to enable memory mirroring. After memory mirroring is enabled, memory can be backups of each other.

The options for the RH8100 V3 server are as follows:

  • Auto: indicates that the system automatically enables mirroring for all memory risers.
  • Manu: indicates that memory mirroring is enabled and that you can manually specify whether to enable mirroring for each memory riser.
  • Disable: indicates that memory mirroring is disabled.
NOTE:
  • When Memory Mirroring is set to Manu:
  • Memory Mirroring MemRiser1 to Memory Mirroring MemRiser16 are displayed in single-system mode.
  • Memory Mirroring MemRiser1 to Memory Mirroring MemRiser8 are displayed for system A in dual-system mode.
  • Memory Mirroring MemRiser9 to Memory Mirroring MemRiser16 are displayed for system B in dual-system mode.
  • Memory Mirroring SCK0 MC0 to Memory Mirroring SCK3 MC1 are unavailable for the RH8100 V3 server.

The options for other servers are as follows:

  • Enable: One node has four double data rate (DDR) channels, in which ch0 and ch2 are used as the images for each other, and ch1 and ch3 are used as the images for each other. That is, two channels are backups of each other. If an error occurs in either of the two channels used as the images for each other, data is read and written using the other channel.
  • Disable
NOTE:

If this parameter is set to Enable, Memory Mirroring SCK0 MC0 to Memory Mirroring SCK3 MC1 are displayed.

Disable

Memory Mirroring MemBoard1 (available only for the RH8100 V3 server)
