FAQs

Q: What does the “L” suffix provide?
A: Large-memory support, enabling up to 4.5 TB per socket when combined with Intel Optane DC Persistent Memory.

Q: Is standard DDR4 memory also supported?
A: Yes, it supports ECC RDIMM/LRDIMM DDR4-2933 alongside Optane DC Persistent Memory.

Q: Do I need a specific platform to reach 4.5 TB per socket?
A: Yes. Your server must support Optane DC PMem and large-memory configurations; check platform documentation.

Q: Are there performance impacts when using PMem?
A: PMem offers higher capacity with different latency characteristics than DRAM; optimal performance depends on App Direct/Memory modes and workload.

Q: Is this suitable for in-memory databases?
A: Yes, the large-memory capability is ideal for SAP HANA and similar in-memory analytics workloads.
