Memory rank sparing
The memory rank sparing feature disables the failed memory from the system configuration and activates a
rank sparing DIMM to replace the failed active DIMM.
You can enable rank sparing memory in the Setup utility, select System Settings ➙ Memory . For more
information, see “Using the Setup utility” on page 145. When you use the memory rank sparing feature,
consider the following information:
• The memory rank sparing feature is supported on server models with an Intel Xeon™ E5-2600 series
microprocessor.
• The maximum available memory is reduced when memory rank sparing mode is enabled.
The following diagram lists the DIMM connectors on each memory channel.
Figure 187. Connectors on each memory channel
Follow the installation sequence for rank sparing mode:
• Install at least one quad-rank DIMM in a channel.
• Install at least two single-rank or dual-rank DIMMs in a channel.
