Frequently Asked Questions
What are the primary performance specifications of the HPE 815101-B21 memory module? +
The HPE 815101-B21 is a 64GB LRDIMM (Load Reduced DIMM) operating at a speed of 2666MT/s (PC4-2666V). With a 4Rx4 rank configuration, this module is optimized to provide high-density memory capacity while maintaining stable performance in demanding enterprise computing environments, helping to reduce memory bottlenecks in multi-socket server configurations.
Is the HPE 815101-B21 64GB LRDIMM compatible with my existing HPE ProLiant Gen10 servers? +
This Smart Memory kit is specifically designed for compatibility with HPE ProLiant Gen10 servers that support DDR4 LRDIMM technology. To ensure complete system stability, verify your server's technical documentation to confirm that the platform supports 64GB capacity modules and the specific PC4-2666V speed requirements for your CPU generation.
Why does this module feature Smart Memory technology? +
HPE Smart Memory is engineered to work exclusively with HPE ProLiant Gen10 servers. It allows for the authentication of memory via the server's firmware, ensuring that the hardware meets HPE's rigorous performance and reliability standards. This integration enables advanced error detection and optimization features, providing a more reliable memory subsystem compared to generic, unverified third-party modules.
What is the physical configuration of the 4Rx4 rank on this 64GB module? +
The 4Rx4 rank configuration signifies that the module uses four ranks of x4 DRAM chips. This architecture is critical for LRDIMMs, as it utilizes a memory buffer to isolate the electrical load from the memory controller. This design allows for higher capacity and faster speeds in large-memory configurations by reducing the stress on the server's memory bus.
Can I mix this HPE 815101-B21 module with different capacity DIMMs in the same server? +
Mixing different capacities or memory types is generally discouraged as it can lead to reduced performance or system instability. Best practice for HPE server deployment is to populate channels with identical modules to maintain balanced memory interleaving and optimal performance. For specific configurations, always consult your server’s QuickSpecs for the supported DIMM population rules and population order.
How does the LRDIMM architecture differ from standard RDIMM for this 64GB module? +
Unlike Registered DIMMs (RDIMMs), the 815101-B21 LRDIMM uses an isolation memory buffer to reduce the electrical load on the memory bus. This buffer allows the server to support a higher total amount of memory by minimizing the signal interference that typically occurs with high-density modules, making it the preferred choice for memory-intensive applications like virtualization and large-scale databases.
Does the HPE 815101-B21 support ECC error correction? +
Yes, this server memory module supports Error Correction Code (ECC) technology. ECC is an essential feature for enterprise-grade server environments, as it automatically detects and corrects single-bit memory errors, preventing data corruption and unexpected system crashes. This level of reliability is mandatory for mission-critical workloads requiring maximum uptime and data integrity.
What are the ideal deployment scenarios for utilizing 64GB LRDIMM modules? +
The 64GB capacity is ideal for memory-hungry workloads, including large-scale virtualization, high-performance computing (HPC), and heavy database management. By utilizing these high-capacity modules, you can maximize the total memory footprint of your HPE ProLiant servers, enabling the consolidation of more virtual machines per physical host and supporting complex in-memory processing tasks with high efficiency.
