Second-generation Xeon Scalable processors are limited to the amount of memory they can address, as follows:
- Processors with an L suffix (eg 8260L): Up to 4.5 TB per processor
- Processors with an M suffix (eg 8260M): Up to 2 TB per processor
- All other processors: Up to 1 TB per processor
The calculation of the total memory per processor includes both the system memory DIMMs and the Persistent Memory DCPMMs installed in the server.
For example:
- A configuration using 12x 64GB DIMMs per processor is a total of 768 GB, which means that neither an M nor an L processor is required
- A configuration using 12x 128GB DIMMs per processor is a total of 1.5 TB, which means that an M processor is required
- A configuration using 6x 32GB DIMMs + 6x 256GB DCPMMs is a total of 1.69 TB which means an M processor is required (an L processor may also be used)
- A configuration using 6x 128GB DIMMs + 6x 512GB DCPMMs is a total of 3.75 TB which means an L processor is required
