A cloud hosting provider in Dubai was looking to upgrade its data center backbone to 100G speeds without breaking the budget or overcomplicating the setup. Their core routers had spare QSFP28 capacity, but the existing 10G infrastructure was becoming a clear bottleneck for east-west traffic between racks.

ALFA TECH’s Solution
We introduced the MikroTik CRS504-4XQ-IN—a small but powerful 100G aggregation switch built for high-speed, low-latency environments:

4x 100G QSFP28 Ports – Ideal for short and long-distance 100G backbone connections.

Marvell Prestera Switch Chip – Delivers reliable, hardware-accelerated switching performance.

Dedicated Management Port – Easy out-of-band access for remote configuration.

Multiple Power Options – Includes PoE-in, DC jack, 2-pin terminal, and dual hot-swappable PSU support.

Compact & Silent – Fits neatly in tight network spaces with efficient passive cooling.

Customer Satisfaction
With the CRS504-4XQ-IN, the hosting provider achieved a seamless upgrade to 100G backhaul between their core routers and rack switches. The unit’s compact size and power flexibility simplified deployment in their high-density racks, while the switch's reliability and cost-efficiency ensured fast ROI. They’re now prepared for future bandwidth expansion—without changing their network architecture.
