Description

256GB Intel Optane DC Persistent Memory module for UCS C890 M5 enables large, affordable memory pools and persistence for fast restart of in-memory datasets. Operates in Memory Mode to expand volatile memory capacity or App Direct Mode for byte-addressable persistent storage alongside DRAM. Requires compatible CPUs/BIOS and proper population with DRAM. Ideal for databases, analytics, and in-memory caching tiers.

Features

- Large 256GB module to scale memory capacity cost-effectively
- Persistent storage for rapid restart of in-memory datasets (App Direct)
- Flexible operation with Memory Mode or App Direct Mode
- Enterprise reliability and security features for data integrity
- Optimized for UCS C890 M5 PMem architecture

FAQs

Q: Does this replace DRAM?
A: No. It complements DRAM. In Memory Mode it extends volatile memory; in App Direct Mode it provides persistent memory alongside DRAM.

Q: What do I need for compatibility?
A: You need a PMem-capable CPU/BIOS on the UCS C890 M5 and an OS/application stack that supports Intel Optane DC Persistent Memory.

Q: Can I mix different PMem capacities?
A: Follow platform guidelines; symmetric capacity per memory controller/channel is recommended for best performance.

Q: Is the data persistent after a reboot?
A: Yes, in App Direct Mode data persists through reboots and power cycles. In Memory Mode, contents are volatile.

Q: Do I need special drivers?
A: Most modern OSes include PMem support, but consult your OS and application documentation and the server HCL for required drivers and versions.
