DIMM/Rank Sparing

Currently, I have blades B200M3 with 16GB (Qty: 12)==192GB total – populated with factory default setting.

  • •1. DIMM Sparing:-- What is usable memory and how many module will be used as spare?
  • •2. Rank Sparing:- What is usable memory and how many module will be used as spare?
  • •3. When I choose DIMM/Rank Sparing and applied it to service profile, OS Windows 2012 is still reporting full capacity—192GB. Why DIMM and Rank sparing is not reserving any spare RAM?

  • Thanks

DIMM/Rank Sparing

Hi Hetal ,

After some investigation about this feature, I want to inform you that the memory sparing is not supported in UCS blade servers.

Recommended to use memory mirroring instead.

Re: DIMM/Rank Sparing

Hi David,

I want to ask that, Is Online Spare Memory support in UCS M460 M4?

Thanks,
