16GB DDR4-2666 ECC RDIMM for Cisco - UCS-MR-X16G2RS-H

Upgrade Cisco UCS environments with the reliability and performance of 16GB DDR4-2666 ECC RDIMM memory from Axiom Networking. This module is engineered for enterprise servers and switches that demand data integrity, continuous operation, and easy compatibility with Cisco hardware. Optimized for virtualization, databases, and dense consolidation, it delivers consistent latency and strong throughput under heavy workloads. Built to complement Cisco UCS ecosystems, this memory module is designed to deliver business-critical reliability while simplifying procurement and deployment for IT teams.

• High-capacity reliability for dense workloads: This 16GB DDR4 memory module provides ample headroom for virtualization, large databases, and memory-intensive applications. With ECC (Error-Correcting Code) protection, it detects and corrects single-bit errors on the fly, reducing the risk of data corruption and system crashes. In a Cisco UCS deployment, where uptime is paramount, ECC memory translates into fewer maintenance windows and more predictable performance across virtual machines and containers.
• DDR4-2666 speed for fast data access: Operating at 2666 MT/s, this RDIMM delivers higher bandwidth and improved memory throughput, enabling faster application response times and smoother multi-tasking in virtualized environments. The higher data transfer rate helps accelerates workloads such as in-memory databases, real-time analytics, and large-scale virtualization, delivering a responsive experience even under peak demand.
• ECC RDIMM for Cisco-grade reliability: Engineered for mission-critical Cisco systems, ECC RDIMM provides robust data integrity with error detection and correction. This helps prevent silent data corruption and minimizes bug-prone memory faults, supporting stable operation in 24/7 data-center workloads and mission-critical Cisco UCS platforms that require consistent performance and predictable behavior.
• Designed for Cisco UCS and Cisco switches: Validated to work with Cisco UCS servers and compatible Cisco networking equipment, this module offers plug-and-play installation, streamlined procurement, and predictable performance across your Cisco infrastructure. By choosing memory tested for Cisco environments, IT teams can reduce compatibility concerns and accelerate deployment timelines while maintaining Cisco-supported warranties and service coverage.
• Efficient operation and long-term durability: DDR4 memory typically runs at a low voltage (1.2V), delivering energy-efficient performance while maintaining robust thermal margins. The module’s design emphasizes reliability in data-center conditions, with components chosen to withstand continuous operation, vibration, and temperature variations that accompany dense Cisco deployments.
