FAQs

Q: Can this DCPMM be used alone without DRAM?
A: In Memory Mode, DCPMM is paired with DRAM acting as cache; App Direct requires DRAM present and OS/application support.

Q: What processors are required?
A: Use supported Intel Xeon Scalable processors and corresponding BIOS/firmware that enable Optane PMem.

Q: Can I mix different DCPMM capacities?
A: Mixing capacities is possible if platform population and interleave rules are followed; consult the server’s memory guidelines.

Q: Is data persistent across power cycles in App Direct?
A: Yes. In App Direct mode, data is persistent across reboots and power loss.
