Keep critical data available after a reboot and expand memory capacity without forcing every workload onto premium DRAM. This 128 GB Intel Optane Persistent Memory module is designed for Cisco UCS environments that need more addressable memory for analytics, virtualization, and large application caches. Operating at 2,666 MHz, it supports demanding server workloads where capacity matters as much as speed. Persistent memory changes the economics of scaling. Instead of paying DRAM prices for every gigabyte, you can place more working data closer to the CPU while preserving state across power loss or maintenance cycles. That makes it a strong fit for environments that need faster recovery, larger memory footprints, and more predictable performance under load. For infrastructure teams, the value is not just capacity. It is the ability to keep high-value data resident, reduce restart penalties, and support memory-intensive services with a more efficient tier of server memory. In Cisco UCS deployments, this module is a practical way to extend platform capability without redesigning the entire stack.
