Description

256GB persistent memory module at 3200 MT/s using a DDR4 DIMM interface to provide large, byte-addressable capacity with persistence for data-intensive workloads. Ideal for in-memory databases, analytics, and VM density, it supports App Direct for persistent namespaces and Memory Mode to expand volatile memory working sets. Requires compatible server platform, BIOS provisioning, and OS support for persistent memory.

Features

- High-capacity 256GB persistent memory DIMM
- 3200 MT/s data rate for higher bandwidth configurations
- Supports both persistent and volatile expansion modes
- Complements DRAM to scale memory footprints efficiently
- Ideal for database, analytics, and virtualization workloads
- Enterprise visibility for configuration and health monitoring

FAQs

Q: Will this operate at full 3200 MT/s in any server?
A: Only if the server platform, CPU generation, and firmware support 3200 MT/s PMem. Otherwise, it may clock down to a supported speed.

Q: What file systems support PMem with DAX?
A: Linux XFS and ext4 support DAX; Windows Server offers DAX-capable NTFS/ReFS features in specific versions. Verify OS version and guidance.

Q: How do I verify health and endurance?
A: Use server management and OS tools (e.g., ipmctl) to view health, utilization, temperature, and media endurance metrics.

Q: Do I need identical capacities per channel?
A: Yes, symmetric population across channels and sockets is generally required for supported modes and optimal performance.
