Memory mirroring:
■
If you select the Memory RAS option, be aware that it is available only with an even
number of memory channels. For example, if you select six DIMMs and select
Reliability/Availability/Serviceability (RAS), mirroring will go into effect on only two
channels with two DIMMS per channel (you cannot implement RAS on three channels). In
this case, two DIMMS would go unused.
For more information regarding memory, see
Cisco UCS B200 M2 Blade Server
You can mix dual voltage DIMMs (operate at either 1.5 V or 1.35 V) and single voltage
DIMMs (operate at only 1.5 V).
Dual-voltage DIMMs can be operated in either of these modes:
• Power Saving Mode at a maximum speed of 1066 MHz
• Performance Mode at a maximum speed of 1333 MHz
If you mix both types of DIMMs in your configuration, the server forces all DIMMs to
operate in Performance Mode.
NOTE: For memory mirroring, DIMM pairing across buses must be identical.
If you only have two DIMMs, they need to be the same PID because you have
one DIMM on each of two buses.
If you have four DIMMs in a 2-CPU system, for example, you can have two
4-GB and two 8-GB DIMMs. One 4-GB/8-GB DIMM pair would located on
Channel A of CPU 1, and one 4-GB/8-GB DIMM pair would be located on
Channel D of CPU 2.
If you have four DIMMs in a 1-CPU system, for example, you can have two
4-GB and two 8-GB DIMMs. One 4-GB/8-GB DIMM pair would located on
Channel A of CPU 1, and one 4-GB/8-GB DIMM pair would be located on
Channel B of CPU 1.
