    Memory Mirroring and RAS, page 30 • Modern processors are designed to support several generations of memory technology. Cisco's Extended Memory Technology allows us to replace high-density DIMMs with multiple lower-density DIMMs in a way that is transparent to the processor and to applications. In some configurations, we are emulating DIMMs that are not available, such as making four 8-GB DIMMs appear to be a single 32-GB DIMM.

  • Page 24: Supported Dimms

    Two DIMMs, each 8 GB dual-rank DDR3-1333 MHz Low Voltage PC3-10600 1. 4 GB single Rank low voltage DIMMs require Cisco UCS Manager version 1.4(1) or later, and the related BIOS package. Low voltage DIMMs require Cisco UCS Manager version 1.2(1) or later, and the related BIOS package.

  • Page 25: Low-Voltage Dimm Considerations

    The two low-voltage DIMMs within a DIMM pair must have the identical manufacturer, type, speed, • and size. Cisco provides spare DIMMs for this product in matched pair kits. • Low-voltage DIMM pairs and standard-voltage DIMM pairs can be mixed in the same server. Note that this causes the system BIOS to default to standard-voltage operation (Performance Mode).
