MEM-2900-512U1GB Use Case
High-Performance Branch Office Routing Upgrade
In a multi-site enterprise, network admins install the MEM-2900-512U1GB-UPG to double the Cisco 2901/2921’s DRAM from 512 MB to 1 GB. This upgrade delivers up to 45% faster throughput under heavy web and file-transfer loads, ensuring consistent application performance and reduced packet loss across branch offices.
Optimized VPN and Security Appliance Throughput
A managed service provider deploys the 1 GB DRAM kit on Cisco 2901 routers to support hundreds of IPsec VPN tunnels at remote sites. The extra memory enables up to 2× higher encryption session capacity, reducing CPU contention and delivering stable, low-latency connections for secure telework and B2B traffic.
Reliable VoIP and Video Conferencing Operations
An educational institution upgrades its campus routers with MEM-2900-512U1GB-UPG to handle concurrent VoIP calls and HD video streams. The expanded DRAM buffer minimizes jitter and call drops, guaranteeing clear audio/video quality and uninterrupted distance learning sessions during peak hours.
