Targeted for enterprise servers requiring data persistence, this NVDIMM-N DDR4 module merges DRAM speed with NAND flash backup to safeguard in-flight data during power loss. Its registered ECC architecture and single-rank x4 configuration deliver exceptionally low-latency, error-corrected performance, making it ideal for mission-critical database caching and virtualization workloads where both uptime and data integrity are non-negotiable.
1. NVDIMM architecture turns system memory into persistent storage, ensuring in-flight transactional data survives power loss for always-on enterprise databases and write-intensive caching layers.
2. ECC protection continuously detects and corrects single-bit memory errors, eliminating silent data corruption that can compromise long-running analytics and virtualized workloads in the data center.
3. Registered signal buffering stabilizes high-density memory configurations, allowing multiple DIMMs per channel to scale capacity without sacrificing signal integrity for large-scale virtualization hosts.
4. The modest 8 GB capacity suits lightweight persistent memory pools or dedicated caching slices, offering a cost-effective building block for tiered storage acceleration in hyperconverged infrastructure.
5. Single Rank x4 organization delivers consistent, lower-latency access patterns under sequential workloads, helping maintain predictable performance for latency-sensitive financial or database applications.
The MTA18ASF1G72PF1Z-2G1Y11AAIG, an 8GB DDR4 NVDIMM, eliminates the volatility barrier for enterprise servers. Its NVDIMM architecture, ECC error correction, registered buffering, and 1.2V efficiency directly address your critical pain points. In a virtualized cluster, an unexpected power loss typically corrupts in-flight VM states. The NVDIMM’s non-volatile persistence lets those states survive and recover instantly, eliminating lengthy checkpoint replay. Meanwhile, ECC protects hypervisor memory from silent bit-flips that would crash VMs. The registered buffer ensures stable signaling when you populate all DIMM slots for maximum VM density, avoiding command-address timing failures. For in-memory databases like Redis, the NVDIMM acts as a persistent write buffer. Transactions committed to DRAM are secured against power failure with microsecond latency, eliminating the performance penalty of disk-based journaling. ECC guards against corruption of critical financial or analytical data. The 1.2V operation cuts power draw and heat in dense rack deployments, lowering your long-term opex.
General Virtualization
For general virtualization hosts, this 8 GB DDR4-2133 Registered ECC NVDIMM should be deployed in balanced quantities to maximize memory channels. Populate six or eight identical modules across all memory channels for a typical dual-socket server, delivering 48–64 GB total capacity per node—ideal for light to moderate VM density. Always install modules in matched sets per memory controller to maintain interleaved performance and ECC protection.
In-Memory Database
In-memory database workloads demand low latency and high resilience, making NVDIMMs particularly valuable for write-ahead logs and persistent cache tiers. Deploy multiple 8 GB modules, populating all channels symmetrically—12 or 16 modules to reach 96–128 GB—to sustain high throughput for Redis or SAP HANA instances. Pairing NVDIMM with traditional DRAM in the same server preserves data durability without sacrificing access speed.
High-Performance Computing
HPC clusters benefit from the module’s single-rank x4 organization and CL15 latency, offering consistent memory bandwidth under parallel workloads. Configure dual-socket nodes with 8 or 16 identical 8 GB Registered ECC DIMMs (64–128 GB per node) to feed many-core processors without bottlenecking memory bandwidth. For memory-intensive simulations, uniformly fill all memory channels to maximize aggregate throughput and keep inter-node communication efficient.
Rigorously tested, compatible with Dell PowerEdge R740, R640, R940, HPE ProLiant DL380 Gen10, and similar servers.
Q: Can I mix this MTA18ASF1G72PF1Z-2G1Y11AAIG with other memory modules of different brands or speeds?
A: Mixing ECC Registered DIMMs of different brands or speeds is not recommended. It may cause instability, post failures, or reduced reliability. All installed modules should match specifications for guaranteed compatibility.
Q: Is this memory compatible with my server platform, such as Intel Xeon or AMD EPYC?
A: This DDR4-2133 ECC Registered NVDIMM is compatible with select Intel Xeon E5-2600 v3/v4 and certain AMD EPYC platforms. Verify NVDIMM support on your motherboard’s qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board’s manual. Typically, populate identical DIMMs per channel starting with slots farthest from the CPU. Balance capacity across memory channels for optimal performance and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This server-grade ECC Registered NVDIMM adheres strictly to JEDEC standards for maximum reliability. Overclocking and XMP profiles are not supported; it operates at the fixed 2133 MT/s speed.
Q: What warranty and typical failure rate can I expect?
A: The module includes a 1-year warranty. As an enterprise-class NVDIMM, it undergoes rigorous qualification and exhibits a very low annualized failure rate when operated within specified environmental conditions.
